The Security Risk of Lost Keys
Losing your keys is more than just an inconvenience — it is a potential security risk. If your keys are lost rather than simply misplaced, anyone who finds them could potentially use them to gain entry to your home, car or office. This is why we always recommend changing your locks or having them re-keyed any time keys are lost or stolen. The cost of re-keying is far less than the cost of a break-in.
When to Re-Key vs Replace Your Locks
Re-keying involves changing the internal pins of your existing lock so that your old keys no longer work, but the lock hardware itself stays in place. It is faster and less expensive than a full lock replacement and is ideal when the lock itself is in good condition. Full lock replacement is recommended when the lock is worn, damaged, or you want to upgrade to a higher-security model.
- Re-keying — from $50 per lock, ideal for when keys are lost or stolen
- Lock replacement — from $150, best when hardware is worn or you want an upgrade
- New keys cut — from $5.50 per key when a spare copy is all you need
