Business security depends on much more than fitting a lock to the front door. Offices, warehouses, retail units, workshops, clinics and shared commercial buildings often have several entrances, internal rooms and staff access points to manage. Without a clear system, keys can be copied, misplaced or passed between people without an accurate record.
Poor key control can leave a business exposed even when its doors and locks appear secure. A former employee may still have a key, a contractor may forget to return one or an unrecorded copy may remain in circulation for years. If nobody knows how many keys exist or who holds them, it becomes difficult to manage access properly.
At Tyne Tees Locks, we help businesses across Newcastle review their locks, identify access risks and put practical security measures in place. We work with organisations of different sizes and understand that every premises has its own layout, staff structure and security requirements.
Improving key control does not always mean replacing every lock or installing a complicated access system. In many cases, the most effective improvements come from better records, clearer responsibilities and a planned approach to issuing, collecting and storing keys.
What Is Key Control?
Key control is the process of managing who can access a property, which areas they can enter and how physical keys are issued, tracked and returned.
A good key control system should allow a business to answer several important questions:
- How many keys exist?
- Which doors does each key open?
- Who currently holds each key?
- When was it issued?
- Has it been returned?
- Are spare keys stored securely?
- Who is authorised to order replacements?
- What happens if a key is lost?
- Can keys be copied without permission?
If a business cannot answer these questions, access is not being managed effectively.
The aim of key control is not to make daily work more difficult. It is to make sure the right people can enter the right areas without giving unnecessary access to everyone.
Why Key Control Matters for Newcastle Businesses
A commercial building may contain valuable stock, customer information, tools, equipment, cash, medication or confidential documents. Even a small premises can have several areas that need different levels of protection.
An office employee may need access to the main entrance and their department but not the server room. A warehouse worker may need access to loading areas but not management offices. A cleaner may need temporary access outside normal working hours without being able to enter every secure room.
When the same key opens every door, or keys are shared freely, the business loses control over who can enter sensitive areas.
This creates several risks:
- Theft or unauthorised access
- Difficulty investigating security incidents
- Former staff retaining access
- Lost keys affecting several doors
- Confidential information being exposed
- Insurance concerns
- Delays during emergencies
- Disruption when locks fail
- Disputes over who had access
Working with experienced commercial locksmiths can help a business identify where access is too broad and where stronger controls may be needed.
Start With a Full Key Audit
The first step is to understand the current situation.
A key audit involves identifying every external and internal door, the type of lock fitted and the keys currently in use. This should include main entrances, rear doors, fire exit access points, stockrooms, offices, cupboards, gates, shutters and plant rooms.
The audit should record:
- Each door and its location
- The type of lock or cylinder
- The key reference
- How many copies are known to exist
- Who holds each copy
- Whether the lock is working correctly
- Whether the door closes and aligns properly
- Whether access should be restricted
- Whether keys can be copied freely
Many businesses discover during an audit that more keys exist than expected. Some may have been cut by previous managers, staff or contractors without being added to any record.
Where the number of keys cannot be confirmed, changing or rekeying affected locks may be the safest way to regain control.
Create a Key Register
A key register provides a clear record of every key issued by the business.
This can be maintained digitally or on paper, depending on the size of the organisation. The important point is that it remains accurate and is updated whenever a key changes hands.
A useful key register may include:
- A unique key number
- The door or access group it operates
- The name of the holder
- Their job role or company
- The date of issue
- Their signature
- The expected return date
- The actual return date
- Details of any loss or damage
- Approval for any replacement
Keys should not be handed to employees informally without recording the issue. Even trusted staff may forget who received a key several months later.
The register should also include spare keys. A spare kept in an unlocked desk drawer is still part of the access system and needs to be controlled.
Assign Responsibility for Keys
One person or a small authorised team should be responsible for key management.
This does not mean they need to hold every key. It means they control the records, approve new issues and make sure returned keys are checked.
Without clear responsibility, several managers may cut or distribute keys independently. This can result in duplicates being issued without anyone seeing the full picture.
The person responsible should:
- Keep the key register updated
- Store spare keys securely
- Approve replacement keys
- Review access when roles change
- Collect keys from departing staff
- Record temporary contractor access
- Respond to lost key reports
- Arrange lock changes when needed
Larger organisations may assign this responsibility to facilities management, security or operations. Smaller businesses may place it with a director or office manager.
Limit Access According to Job Role
Employees should only receive the access they need to perform their work.
Giving every staff member a key to every area may feel convenient, but it weakens control and increases the impact of a lost key.
A role-based approach may include:
- General staff access to entrances and shared areas
- Department managers accessing offices within their section
- Finance staff accessing cash or record rooms
- Maintenance staff accessing plant and service areas
- Senior managers holding wider access
- Cleaners receiving limited or time-specific access
A commercial locksmith in Newcastle can help plan a lock arrangement that reflects these different access needs.
This may involve separate locks, keyed-alike groups or a master key system. The right option depends on the number of doors, the building layout and how staff move through the premises.
Review Access When Staff Roles Change
Key permissions should not remain fixed when an employee changes job role.
A person moving from one department to another may no longer need access to their previous area. A promotion may require broader access, while a change in duties may reduce it.
The key register should be reviewed when:
- An employee changes department
- A manager takes on new responsibilities
- A contractor begins or finishes work
- A temporary worker leaves
- A business restructures
- Staff move between sites
- A new restricted area is created
Old keys should be returned before new ones are issued where possible.
This reduces the number of active keys and prevents access from accumulating over time.
Collect Keys Immediately When Staff Leave
Departing employees should return all company keys as part of the leaving process.
This should be treated with the same importance as returning laptops, identification cards and other business property.
The business should confirm:
- Which keys were issued
- Whether all copies have been returned
- Whether the employee had permission to copy them
- Whether any keys were lost during employment
- Whether access was shared with anyone else
If a key is not returned, the risk should be assessed promptly.
The business should consider which doors the key opens, whether it is labelled and whether the former employee could identify the premises. If the key provides access to important or sensitive areas, changing the affected lock may be advisable.
Where one key opens several doors, the impact can be greater. This is why restricted access and well-designed key hierarchies are valuable.
Manage Contractors and Temporary Access
Contractors, cleaners, delivery teams and maintenance workers may need access to business premises, often outside normal working hours.
Temporary access should be managed just as carefully as employee access.
Businesses should avoid handing contractors a main master key unless there is a clear need. A limited key that opens only the required areas is usually more appropriate.
A temporary key process should record:
- The contractor’s name
- Their company
- The reason for access
- The key issued
- The date and time of issue
- The expected return time
- The person authorising access
- Confirmation that the key was returned
Where possible, a member of staff should supervise access to highly sensitive areas.
If contractors require regular entry, the business should review whether a dedicated key group or separate lock would provide better control.
Store Spare Keys Securely
Spare keys should not be kept in obvious or unsecured locations.
Common but unsuitable storage places include:
- Desk drawers
- Reception cupboards
- Shelves near the entrance
- Unlocked cabinets
- Labelled hooks in public areas
- Plant pots or boxes outside
- Shared staff rooms
Keys should be stored in a locked cabinet or safe that is accessible only to authorised people.
Labels should use coded references rather than full addresses or clear room names where practical. If a key cabinet is stolen or accessed, obvious labels can make misuse easier.
The cabinet itself should be fixed securely rather than left portable.
Businesses with many keys may benefit from a cabinet that includes numbered hooks, issue records or controlled access.
Have a Clear Lost Key Procedure
Every employee should know what to do if a key is lost.
Delays in reporting can increase the security risk. Staff may feel embarrassed or worry about being blamed, but the business needs the information quickly to decide what action is required.
A lost key procedure should include:
- Reporting the loss immediately
- Confirming which key is missing
- Recording where and when it was last seen
- Establishing whether it was labelled
- Checking whether it could be linked to the premises
- Reviewing which doors it opens
- Deciding whether locks need changing
- Updating the key register
- Issuing a replacement only with approval
Not every lost key requires an immediate full lock change. The decision depends on the level of risk.
A key lost inside a secure staff area may present less concern than one lost with an address label in a public place. A master key or key to a high-value storage room should be treated more seriously than a key to a low-risk internal cupboard.
Consider Restricted Key Systems
Some common keys can be copied easily without the business being informed.
Restricted key systems are designed to provide greater control over duplication. Replacement keys are generally supplied through an authorised process rather than copied at any standard key-cutting shop.
This can help a business keep a more accurate record of how many keys exist.
Restricted systems may be useful for:
- Offices with confidential information
- Schools
- Healthcare premises
- Property management companies
- Warehouses
- Retail businesses
- Multi-site organisations
- Buildings with frequent staff changes
A restricted system still needs good management. It should not replace a key register, secure storage or clear reporting procedures.
We can explain the available options and help businesses choose a system that is proportionate to their needs.
Use Master Key Systems Carefully
A master key system allows different keys to open different groups of doors while a higher-level key opens several or all locks.
This can make access easier to manage, particularly in buildings with many rooms or departments.
For example:
- An employee key opens the main entrance and one office
- A department key opens all rooms in that department
- A manager key opens several departments
- A site master key opens the full building
The benefit is that authorised users can carry fewer keys without giving every person unrestricted access.
However, master keys need strong control because losing one may affect several doors. The number of master copies should be kept low and every holder should be recorded.
Spare master keys should be stored securely and never labelled in a way that identifies the building.
Inspect Locks and Doors Regularly
Key control is only effective if the locks themselves work properly.
Commercial doors often receive heavy use. Handles, cylinders, hinges and locking mechanisms can wear over time.
Warning signs include:
- A stiff key
- A loose handle
- A door that needs pushing or pulling to lock
- Scraping against the frame
- A latch that does not engage
- A cylinder that feels loose
- Grinding or clicking sounds
- A lock that works only in certain weather
- A door that fails to close automatically
These problems should be addressed before the lock fails completely.
A worn or misaligned door can place pressure on a new lock, so replacing the cylinder alone may not solve the issue. We inspect the full door and locking action to identify the actual cause.
Planned maintenance can reduce emergency callouts and prevent staff being locked out or unable to secure the building.
Secure All External Access Points
The front entrance is not the only route into a commercial property.
Businesses should review:
- Rear doors
- Side entrances
- Loading bays
- Roller shutters
- Gates
- Roof access
- Shared corridors
- Basement doors
- Fire exit access from outside
- Windows
- Internal doors leading from communal areas
Less visible entrances are sometimes overlooked because staff use them less often. However, they may offer easier access if locks are old, damaged or poorly fitted.
External doors should close securely and should not be left propped open for convenience.
Delivery procedures should also be reviewed. Staff may leave rear doors open during loading, creating an opportunity for unauthorised entry.
Protect Sensitive Internal Areas
Not every security measure needs to focus on the building perimeter.
Internal rooms may require additional protection, including:
- Server rooms
- Finance offices
- Personnel record storage
- Medication cupboards
- Stockrooms
- Tool stores
- Cash offices
- Archives
- Plant rooms
- Management offices
Access to these areas should be limited to staff with a clear business need.
A separate lock can create an additional security layer even if someone gains access to the main building.
Businesses should also avoid leaving keys to restricted rooms nearby. A stockroom key hanging at reception provides little protection if anyone can take it.
Review Security After an Incident
Any attempted break-in, theft or unauthorised access should trigger a security review.
The review should consider:
- How entry was gained
- Whether a key was used
- Whether doors or locks were damaged
- Who had access at the time
- Whether key records are accurate
- Whether any keys are missing
- Whether CCTV or alarm systems were activated
- Whether access permissions are too broad
- Whether locks need replacing or upgrading
A damaged lock may continue to operate while no longer providing reliable security. It should be inspected professionally.
The incident may also reveal procedural weaknesses, such as staff sharing keys or leaving doors unsecured.
The aim should be to correct the cause rather than simply replace the damaged part.
Keep Insurance Requirements in Mind
Commercial insurance policies may include requirements relating to locks, shutters, alarms and building security.
Businesses should review their policy documents and confirm whether specific lock standards are required.
A lock that functions normally may not meet the insurer’s expectations. Equally, a suitable lock may not provide the expected protection if the door or frame is weak.
Businesses should keep records of security improvements, lock replacements and professional inspections. These may be useful when renewing a policy or responding to a claim.
We can inspect existing locks and explain the practical options, but insurance requirements should be confirmed directly with the provider.
Combine Physical Security With Staff Procedures
Locks are only one part of business security.
Staff behaviour can strengthen or weaken the protection provided by the building.
Employees should be encouraged to:
- Keep keys on their person
- Avoid lending keys to colleagues
- Report losses immediately
- Close and lock doors after use
- Challenge unknown visitors appropriately
- Avoid propping open secure doors
- Return temporary keys promptly
- Keep alarm codes confidential
- Report damaged locks and handles
- Follow opening and closing procedures
Training does not need to be complicated. Clear instructions during induction and occasional reminders can improve consistency.
Managers should also lead by example. A key control policy will not work if senior staff ignore it.
Review Opening and Closing Procedures
The start and end of the working day are important security points.
The person opening the premises should know:
- Which doors need unlocking
- Whether there are signs of forced entry
- How to disarm alarms
- Which areas should remain locked
- Who to contact if a lock is damaged
The closing procedure should include:
- Checking that staff and visitors have left
- Locking internal restricted areas
- Securing windows
- Checking loading and rear doors
- Confirming shutters and gates are closed
- Setting the alarm
- Recording any issue
- Making sure keys are not left behind
A checklist can reduce the risk of one entrance being overlooked.
Businesses with several closing staff should define who is responsible for each part of the building.
When Should Commercial Locks Be Changed?
Businesses should consider changing locks when:
- Keys are missing
- An employee leaves without returning them
- Unauthorised copies may exist
- The premises changes ownership
- A new tenant takes over a commercial unit
- A burglary or attempted break-in occurs
- The lock is worn or damaged
- Access permissions need restructuring
- The current system is difficult to manage
- Nobody knows how many keys exist
The work may involve replacing a complete lock, changing a cylinder or reconfiguring a wider system.
We assess the existing hardware before recommending the most appropriate option. Replacing every part is not always necessary, but security concerns should not be ignored.

Improve Your Business Security With Tyne Tees Locks
Strong building security starts with knowing who can enter, which areas they can access and how every key is controlled.
A clear key register, secure storage and prompt collection from departing staff can reduce many common risks. Businesses should also inspect locks regularly, restrict access according to job role and review their procedures whenever staff or premises change.
Where existing locks no longer support the way the business operates, a planned commercial system can provide better control and easier management.
We work with businesses across Newcastle to repair locks, update access arrangements and improve key security. Whether you manage one commercial unit or several sites, we can assess your current setup and recommend a practical way forward.
