How Often Should a Business Change Its Locks and Access Codes?

Most businesses install good locks and access systems, then only think about them again when something goes wrong. The risk is that over time, keys and codes spread far beyond your current staff list. Former employees, contractors and even old cleaners may still have a way into your premises.

Reviewing and updating locks and access codes on a regular schedule is one of the simplest ways to reduce that risk.

Triggers that should always prompt a change

Some events should almost automatically trigger a lock or code change:

• An employee with keys or access codes leaves the business.
• Keys are lost, stolen or not returned.
• You experience a break in or attempted break in.
• You take over a new tenancy or expand into additional space.

In these situations, waiting “to see what happens” leaves your business exposed. A commercial locksmith can quickly rekey external doors, update restricted key systems and reprogram access control so that only current, authorised people can get in.

Setting a regular review cycle

Beyond those obvious triggers, it is wise to set a regular security review. Many businesses benefit from an annual lock and access audit, and higher risk sites may need checks every six months. During a review, your locksmith will look at:

• Who currently holds keys and what they can open.
• Which codes, cards or fobs are active in your system.
• The condition of locks, door hardware and access control units.

This structured approach turns security changes from a reactive emergency into a planned, budgeted activity. Over time, you can upgrade weaker points, retire old keys and improve record keeping so you always know who can open which doors.

How restricted key systems improve control

For many offices, warehouses and multi site businesses, restricted key systems are a smart upgrade. These systems use patented key profiles that can only be cut by authorised locksmiths, and only with written approval from the key holder. That means staff cannot quietly copy keys at a shopping centre kiosk.

A well designed restricted key system also gives you a clear hierarchy: grand master keys for owners or managers, sub masters for team leaders and individual keys for specific rooms or areas. When someone leaves, you can simply collect their key and know there are no unauthorised copies in circulation.

Managing access codes, cards and fobs

Electronic access systems need regular housekeeping too. Over time, it is easy to accumulate long lists of active PIN codes, cards and fobs. If you do not remove access promptly when people leave, you lose many of the benefits of the system.

Best practice is to:

• Assign unique codes or cards to each person, not shared ones.
• Remove or disable access on the day an employee or contractor finishes.
• Run periodic audits of active credentials against your HR or contractor list.
• Change shared codes (for example, alarm codes) at least annually or when staff changes.

A locksmith with access control expertise can help you set up these processes and provide training for your internal admin team.

Balancing security, convenience and cost

Changing locks and codes too often can frustrate staff and add unnecessary cost, while changing them too rarely increases risk. The right balance depends on your industry, the value of assets on site and how many people require access. For example, a shop with high value stock and casual staff turnover may need more frequent updates than a small professional office with long term employees.

Working with a locksmith who understands commercial environments lets you design a schedule that makes sense for your business. You get a clear plan instead of ad hoc decisions made under pressure after something has gone wrong.
