Why lock changes matter
A lock does not last forever. Worn parts, lost keys and changes in who lives in your home all affect how safe a lock is. The good news is that changing a lock is quick and often inexpensive.
The seven signs
If any of these sound familiar, it is worth acting.
- You moved into a new home and do not know who has keys.
- You lost a key, or one was stolen.
- A tenant, worker or former flatmate still has a key.
- The lock sticks, jams or needs force to turn.
- The key is worn or bends in the lock.
- The lock or door looks damaged after a break-in attempt.
- Your lock is old and you want better security.
Repair or replace?
If the problem is a loose handle or a stiff latch, a repair may be enough. If keys are missing, or the lock is worn or damaged, a new lock is usually the better choice.
