Locksmith After an Eviction in Buffalo, NY: A Landlord’s Guide to Changing the Locks the Right Way
You went through the notices, the court date, and the wait. The sheriff has finally executed the warrant and handed the unit back to you. Now there’s one job left before you can breathe: getting the locks changed so the person who just left — and anyone they ever gave a key to — can’t walk back in. This guide walks Buffalo-area landlords through when you can legally change the locks after an eviction, why it matters, what it costs, and how to get it done the same day. It also includes a reference table of 50+ police stations across our service area, because knowing your local department is part of protecting your property.
“The number one call we get from landlords comes on the same afternoon the sheriff hands them the keys. That’s exactly the right time to call — the property is legally yours again, and the last thing an old copy of that key should do is still open the door.” — Simon Goodman, owner, Defense Locksmith
First, the Law: When Can You Legally Change the Locks in New York?
This is the part landlords get wrong, and it’s an expensive mistake. In New York, you cannot change the locks, remove belongings, or shut off utilities to force a tenant out on your own. That’s called a “self-help” eviction, and it’s illegal statewide — even if the tenant stopped paying months ago. Changing the locks is the final step of a legal process, not a shortcut around it. Here is the order it has to happen in:
- Serve the proper written notice. The type and timeline depend on the situation — a demand for unpaid rent, or a notice ending the tenancy.
- File the eviction case (nonpayment or holdover) in the correct city, town, or village court.
- Attend the hearing. If the court rules in your favor, it issues a Judgment of Possession.
- The court issues a Warrant of Eviction.
- A sheriff, marshal, or constable executes the warrant after the required notice, physically restoring possession to you.
- The moment that officer hands the unit back, it is legally yours to secure.
- Call a locksmith and rekey or replace every exterior lock that day.
Do not change the locks before that warrant is executed. This article is general information for property owners, not legal advice — confirm your specific steps with a landlord-tenant attorney or your local court clerk.

Why Change the Locks the Same Day You Get Possession
Once the unit is legally yours, the clock matters. A departed tenant may have made copies, handed keys to a partner or family member, or simply never returned every key you issued. Rekeying closes all of that in one visit. Here’s what a same-day lock change protects you from:
- Former tenants (or their contacts) re-entering after they’ve been removed
- Unaccounted-for copies made at a hardware store during the tenancy
- Disputes over property left behind — a secured unit protects both sides
- A new tenant inheriting locks the last three tenants also had keys to
- Insurance and liability gaps while a unit sits empty and accessible
“Ninety percent of the time you don’t need new hardware — you need the cylinders rekeyed so every old key is dead. It’s faster, it’s cheaper, and it’s just as secure. Save the replacement budget for the doors that are actually damaged.” — Simon Goodman

Rekey, Replace, or Master Key? A Landlord’s Decision Table
Not every eviction calls for the same fix. Here’s how we help owners choose:
| Option | Best for | Turnaround | Relative cost | What it does |
|---|---|---|---|---|
| Rekey | Most turnovers; locks that still work fine | Same day | $ | Re-pins the existing cylinder so every old key stops working |
| Replace | Damaged, worn, forced, or low-grade locks | Same day | $$ | Brand-new hardware plus a fresh set of keys |
| Master Key System | Owners with multiple units or a whole building | Planned install, then minutes per turnover | $$$ up front, $ per turnover | One master key opens all; each unit stays unique |
| Smart / Keypad Lock | Frequent turnovers; no more handing out brass | Same day | $$ | Change a code between tenants instead of cutting keys |

How Our Eviction Lock-Change Service Works
We do this constantly for Buffalo-area landlords and property managers. The process is simple and fast:
- Call us with the property address and how many exterior doors need work.
- We arrive the same day — often within the hour for emergencies.
- We rekey or replace every exterior entry lock so all previous keys are void.
- You get a fresh set of keys, cut on the spot.
- Optional: we install a keypad or smart lock so your next turnover is a code change, not a key cut.
- Own several units? We can fold the property into a master key system so future turnovers take minutes.
“If you own more than a couple of units, stop buying a new lock every turnover. One master key system, and we rekey a unit in minutes the day it turns over. You hold one key, the tenant holds theirs, and nobody inherits the last tenant’s copies.” — Simon Goodman
Buffalo Metro Police Stations: A Property Owner’s Reference (50+)

Frequently Asked Questions
Can I change the locks myself before the sheriff removes the tenant?
No. In New York, changing the locks before the warrant of eviction is executed is an illegal self-help eviction and can expose you to real liability. Wait until the officer restores possession — then secure the unit immediately.
Is it cheaper to rekey or to replace the locks?
Rekeying is almost always cheaper and just as secure, as long as the existing locks are in good shape. We only recommend replacement when hardware is damaged, worn out, or too low-grade to trust.
How fast can you get to my rental?
Same day across the Buffalo metro, and our 24/7 emergency service is often on-site within the hour.
Do you handle commercial evictions too?
Yes. Our commercial locksmith team rekeys storefronts, offices, and multi-tenant buildings, including panic hardware and master systems.
Which towns do you cover?
All of Erie and Niagara counties, plus the Buffalo-side communities of Genesee and Orleans. See the full list on our service areas page.
