Security & Storage 21 May 2026 By Ashley Marshall

Quick Answer

You must then promptly contact your local police firearms licensing department to report the loss and seek their advice, as this constitutes a security breach. It is highly recommended to replace the cabinet lock or the entire cabinet to restore full security.

Losing your gun cabinet keys can be a worrying situation for any responsible certificate holder. Your primary concern should always be the secure storage of your firearms and ammunition to prevent unauthorised access. This guide outlines the immediate and follow-up steps you should take, aligning with the expectations of UK firearms law and licensing authorities.

Immediate Steps When Keys Are Lost

  1. Stop and Search Thoroughly: Before panicking, retrace your steps and conduct a thorough search of all likely places. It's surprising how often keys turn up in an overlooked pocket or under a cushion.
  2. Assess Security Risk: If the keys are lost in a public place, or you suspect they may have been stolen, the risk of unauthorised access is higher. Consider if the keys are identifiable to your cabinet or address. If there's any doubt about where they are, assume the worst and proceed with the following steps.

Securing Your Firearms

Your absolute priority is to ensure the firearms within the cabinet remain secure. If you have spare keys that are stored completely separately and securely (e.g., at another trusted location or with another authorised person, as discussed in our guide on Can You Share a Gun Cabinet in the UK? What Certificate Holders Need to Know), use them to access the cabinet.

If you do not have spare keys, or if your spares are also compromised, you face a dilemma. You cannot leave firearms unsecured. Options include:

Reporting to the Police

Even if you locate your keys, or if you had spare keys, the loss of keys for a firearm cabinet is a security incident that must be reported. Contact your local police firearms licensing department without delay. Do not wait. This is not just a recommendation; it's a critical part of your responsibility as a certificate holder. While the loss of keys isn't the same as a lost or stolen firearm, the principle of reporting potential security breaches is vital. For guidance on reporting other security incidents, you might find our guide on What Should You Do If Your Firearm or Shotgun Is Lost or Stolen in the UK? helpful for context.

When you contact them, be prepared to provide:

The police will advise you on the necessary steps, which may include replacing your cabinet or changing the lock. They may also arrange for an inspection, although routine visits are usually booked in advance as explained in Can the Police Inspect Your Gun Cabinet Without Warning in the UK?.

Replacement Keys and Cabinet Security

If your original keys are genuinely lost and unrecoverable, you have a few options to restore cabinet security:

Always ensure any new keys are stored securely and separately from any spare sets, in a location known only to you or authorised users.

Prevention is Key

To minimise the risk of losing your gun cabinet keys:

Practical Bottom Line

Losing your gun cabinet keys is a serious security incident. Your immediate actions-securing your firearms, reporting the loss to your local police force, and taking steps to re-establish full security-are paramount. Always consult your local police firearms licensing department for specific advice relevant to your certificate conditions and local policies. Staying proactive and transparent is key to maintaining your certificate and ensuring public safety.

Frequently Asked Questions

Do I have to report lost gun cabinet keys to the police?

Yes, absolutely. The loss of gun cabinet keys constitutes a security breach and must be reported to your local police firearms licensing department without delay. They will advise you on the necessary next steps to ensure the continued security of your firearms and compliance with your certificate conditions.

Can I just get a new lock for my cabinet if keys are lost?

In many cases, yes, replacing the lock on your existing gun cabinet is a viable and often recommended solution to restore security. Ensure the new lock meets appropriate security standards and is fitted professionally. You should still report the original key loss to the police beforehand.

What if I have spare gun cabinet keys?

If you have a spare set of keys, you can use them to access your cabinet and secure your firearms. However, the loss of your primary set still needs to be reported to the police firearms licensing department. You should also consider changing the lock or cabinet to remove any risk associated with the lost keys, as their whereabouts remain unknown.

How can I prevent losing my gun cabinet keys again?

To prevent future losses, always keep your keys in a designated, secure, and discreet location. Store any spare keys separately in a completely different, secure place. Avoid attaching any identifying tags to your keys and only carry them when absolutely necessary to access your cabinet.
