Why Landlords Must Rekey Between Tenants
When a tenant moves out, you have no idea how many copies of the key are floating around. They might have given one to a friend, a contractor, or a family member. Even with the best intentions, keys get lost or forgotten.
Most state and local landlord-tenant laws require you to provide a secure premises at move-in. That means new tenants have a reasonable expectation that old tenants can't walk back in. Failing to rekey can expose you to liability if a break-in occurs and it's discovered you never changed the locks.
Beyond legal requirements, rekeying protects your investment. An unauthorized entry can lead to theft, property damage, or worse. A simple rekey between every tenancy is cheap insurance.
Rekey vs. Replace: Which Is Right for Your Rental?
Rekeying means a locksmith adjusts the internal pins inside the existing lock cylinder so the old keys no longer work. You keep the same hardware. It takes minutes per lock and costs a fraction of full replacement.
Rekey when:
- The lock hardware is in good working order
- You're on a standard turnover schedule and the locks are less than 5–7 years old
- You want to save money and avoid patching new holes in the door
Replace when:
- The lock is sticky, rusted, or the deadbolt doesn't fully extend
- You're upgrading security to ANSI/BHMA Grade 1 or Grade 2 deadbolts
- You're installing smart locks or keyless entry for property-management convenience
For most standard turnovers, rekeying is the fastest and most cost-effective choice. A mobile locksmith can rekey an entire unit—entry, deadbolt, and any keyed knobs—in one visit.
Legal & Lease Considerations
Check your state and local ordinances. Some jurisdictions explicitly require landlords to rekey or replace locks between tenants. Others require it only upon tenant request. Even if the law is silent, your lease should spell out the policy.
Include a clause that states locks will be rekeyed at turnover and that tenants must return all keys at move-out. This sets the expectation and gives you documentation if a dispute arises.
If a tenant requests a lock change mid-lease—often because of domestic violence, stalking, or lost keys—many states require you to comply within a set number of days and allow the tenant to deduct the cost from rent or seek reimbursement. Know your local rules and act quickly. A licensed, mobile locksmith can often respond the same day.
Your Tenant-Turnover Lock Checklist
Use this simple list every time a tenant moves out:
- Collect all keys. Count them against your move-in inventory. Document any missing keys in the move-out inspection report.
- Inspect every lock. Test the deadbolt throw, check for loose strike plates, and confirm the door closes and latches smoothly.
- Schedule the rekey before the new tenant moves in. Don't wait until the day of move-in. A mobile locksmith can come to your property on your timeline.
- Rekey the entry door, deadbolt, and any keyed interior doors. Don't forget garage side-doors, storage closets, or pool gates if they're part of the unit.
- Label and store one master set. Keep a labeled master key set in a secure location for emergencies. Never give out your only copy.
If you manage multiple units, ask your locksmith about master keying. A master-key system lets you open every unit with one key while each tenant has a unique key that opens only their door. It simplifies property management without sacrificing tenant privacy.
How Much Does It Cost to Rekey a Rental?
Rekeying a single-family rental typically costs far less than replacing all the locks. Expect to pay per lock cylinder, with volume discounts if you manage multiple properties or rekey several units at once.
At Half Off Locksmith, we quote flat-rate pricing up front before dispatch—no hidden trip fees, no surprises. Our mobile service comes to your property, so you don't have to remove doors or haul hardware to a shop. That saves you time and money on every turnover.
Compare that to full lock replacement, which includes new hardware, installation labor, and often patching old bolt holes. Rekeying keeps your costs predictable and your turnaround fast.
Smart Locks & Keyless Entry for Landlords
If you manage short-term rentals or want tighter access control, smart locks eliminate the rekey step entirely. You issue temporary codes to each tenant and delete them at move-out. No keys, no copies, no guesswork.
Before you buy, check the backset and bore dimensions of your existing doors. Most residential deadbolts use a 2⅜″ or 2¾″ backset and a standard 2⅛″ bore. Many smart locks are designed to fit these specs as direct replacements.
Smart locks also create audit trails—you can see exactly when a door was opened. For landlords juggling maintenance crews, inspections, and tenant access, that visibility is valuable. Just make sure your lease discloses any electronic monitoring in compliance with local privacy laws.
