Broken key in the lock? First steps to take

Keep the fragment and stop forcing the lock

Put the piece in your hand somewhere safe. Do not push another key into the cylinder or try to glue the pieces together inside it. This can push the fragment further in or contaminate the mechanism.

If the door is already open, avoid closing it until you know you can secure it and get back through normally. Keep any alternative entrance available where it is safe to do so.

Tell the locksmith what happened before it broke

Was the key stiff for several days? Did the handle need lifting? Was the key bent or cracked? These observations help distinguish a damaged key from a lock or door problem. Extracting the fragment is only part of the job if the underlying cause remains.

Information to have ready

• Your suburb, address and whether you are locked out.
• Whether any fragment is visible at the front of the lock.
• The lock brand, if you can see it without dismantling anything.
• Whether an intact spare key is available.
• Any attempt already made to remove the fragment.

Will the whole lock need replacing?

Not necessarily. The outcome depends on the fragment, the condition of the cylinder and any damage. Ask the locksmith to explain extraction, testing and any additional repair or replacement before going ahead.

Once access is restored, have the lock checked with a sound key. Continuing to use a damaged or bent spare can leave you with the same problem again. If the door cannot be secured, phone for help rather than waiting for an email response.
