Check My DepositWisconsin 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 Wisconsin 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 Wisconsin Deposit (Free)Regardless of whether a key replacement and lock change charges deduction is valid, your Wisconsin landlord must provide a written itemized statement of all deductions within 21 days. Each line item must identify the specific charge and dollar amount. A vague entry like “key replacement and lock change charges: $X” without further detail is generally insufficient under Wis. Stat. §704.28. If the itemization was missing or untimely, the deduction may be invalid regardless of its merits.

Key Replacement and Lock Change Charges deductions can be legitimate in some circumstances in Wisconsin, 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.
