Frequently Asked Questions

If you have lost your keys, we highly recommend rekeying your locks rather than just cutting a new key.

Rekeying changes the internal mechanism of the lock so that the old, lost keys will no longer work, ensuring that anyone who finds them cannot access your home.

This is a fast, secure, and cost-effective alternative to replacing the entire lock hardware.

The cost of cutting a standard house key is generally very affordable. While prices can vary slightly depending on the specific key blank, it is a low-cost service.

However, for specialised security keys or restricted keys that require authorisation, the cost may be slightly higher due to the unique blanks and security procedures involved.

We can only duplicate restricted or security keys if you are the authorised signatory for that specific key system.

Restricted keys are legally protected designs that prevent unauthorised copying, meaning you must provide proof of authority (usually a signature match) before we can cut a copy.

This system provides a much higher level of security for homes and businesses compared to standard keys.

Yes, our mobile locksmiths are equipped with specialised extraction tools to remove broken key fragments from locks without damaging the mechanism.

Please do not try to fish the piece out yourself with superglue or sharp objects, as this often pushes the fragment deeper or damages the lock, potentially requiring a more expensive replacement.

For a standard residential key, the cutting process is very fast and usually takes just a few minutes.

Our mobile vans are fully equipped with precision key-cutting machines, allowing us to cut and test duplicate keys for you immediately on-site.
