Common questions
Rekey or replace?
Rekeying changes the inside pins so old keys stop working, and costs less than new locks. Replace if the lock is damaged or old.
When rekey?
After moving in, losing keys, or an ex-roommate or contractor had keys. It is a low-cost way to reset who has access.
Does it take long?
No. A locksmith rekeys most locks in 10 to 20 minutes each, so a whole house is usually done in about an hour.
