Question 1

Does Illinois require a lock change between tenants?

Accepted Answer

Yes. Under 765 ILCS 705 §15, landlords must change or rekey locks on or before the day a new tenant moves in.

Question 2

What's the difference between rekeying and replacing?

Accepted Answer

Rekeying changes the internal pins so old keys no longer work — existing hardware stays. Replacement installs brand new locksets. Both satisfy the legal requirement.

Question 3

Can this be done during my standard turn?

Accepted Answer

Yes — lock service is scheduled as part of your turn. No separate appointment needed.

Question 4

What if my back door has a different lock configuration?

Accepted Answer

We'll assess on arrival and bill any additional cylinders at $35 each.

Illinois law requires it. We make it easy.

Every tenant turnover requires a lock change or rekey under Illinois law (765 ILCS 705 §15). ATP can handle it during your turn — no separate locksmith appointment, no extra coordination.
