Check My DepositIllinois landlords can charge reasonable costs for unreturned keys, but the charge must be proportionate to the actual cost. Key duplication typically costs $2–$10 per key. Charging for a full rekeying system ($200–$400) because a tenant forgot to return one copy of a standard key is generally disproportionate — unless security was genuinely compromised. If you returned all keys but your landlord claims otherwise, the burden is on them to prove the keys were not returned. Normal wear on key fobs, garage openers, and similar items from regular use is not chargeable under Illinois law. Lock changes during tenancy are typically the landlord's cost to bear unless you caused the need for the change through negligence or breach of lease.
Return ALL keys at move-out and get a written receipt. Keep this receipt — it proves you returned keys and protects you from false key charges. If possible, photograph all returned keys before handing them over. A full rekeying charge for a single unreturned key is very likely disproportionate.

Check My Illinois Deposit (Free)Regardless of whether a key replacement and lock change charges deduction is valid, your Illinois landlord must provide a written itemized statement of all deductions within 30 days.

A vague entry like “key replacement and lock change charges: $X” without further detail is generally insufficient under 765 ILCS 710/1.

Questions
Your Illinois landlord has 45 days after your move-out date to return your security deposit along with an itemized statement of any deductions. This deadline is set by 765 ILCS 710/1.
If your landlord misses the 45-day deadline, you may be entitled to up to 3× the amount wrongfully withheld under 765 ILCS 710/1(c). The penalty applies when your landlord acted in bad faith.
No. Illinois law under 765 ILCS 710/1 explicitly prohibits landlords from deducting for normal wear and tear. This includes faded paint, minor scuffs, small nail holes, and carpet thinning from regular use. Deductions must be for actual damage beyond what normal living causes.
Key Replacement and Lock Change Charges deductions can be legitimate in some circumstances in Illinois, but must be specific, documented, and beyond normal wear and tear. Return ALL keys at move-out and get a written receipt. Keep this receipt — it proves you returned keys and protects you from false key charges. If possible, photograph all returned keys before handing them over. A full rekeying charge for a single unreturned key is very likely disproportionate.
First, check whether the deduction appeared in a proper itemized statement provided within 45 days of move-out. If it did, evaluate whether the charge reflects actual damage beyond normal wear. If the itemization was late or missing, the deduction may be invalid regardless of its merits under 765 ILCS 710/1. Use our free analysis tool to check your specific situation.
