Every time a tenant moves out, you lose track of how many keys exist to that unit. Former tenants, their friends, dog walkers and contractors may all have copies. Rekeying between tenants is the simplest way to start each lease clean.

Rekey or replace?

Rekeying changes the pins inside the existing cylinder so old keys stop working. The hardware stays on the door, so it is usually cheaper than new locks. Replace instead when the lock is worn, damaged or low quality.

A turnover checklist

• Collect every key the tenant was given, and note which are missing.
• Rekey all exterior doors, including back, side and garage entry doors.
• Rekey or reset mailbox locks and storage units if you control them.
• Change keypad and smart lock codes, and remove the old tenant from any app.
• Check that every deadbolt throws fully and the strike plates are secure.
• Record the new key numbers and how many copies you hand out.

Key everything alike

If you manage several doors, have them keyed alike so the tenant carries one key. For multiple units, a master key system lets each tenant open only their own door while you keep one key for all of them.

Check your local rules

Some cities and states require landlords to change or rekey locks between tenancies. Check the rules where your property is.
