Moving in, roommate left, contractor had a copy, lost a key — any of these are solid reasons to rekey. It is one of the most practical steps you can take for home security in New York.
Rekeying keeps your existing locks but changes the pins inside each cylinder, so the old keys stop working and a fresh set takes over. Every cylinder in the home can be keyed to one new key — front door, deadbolt, and back door all on the same key. The hardware on the door stays exactly as it was.
Between tenants, a rekey is the standard turnover step — fast, documented, and far simpler than replacing hardware across a portfolio. We rekey multi-unit buildings across NYC with labeled key sets per unit and a master system for management, with invoices formatted for your records.
A stolen bag with keys and ID inside is the scenario that cannot wait — the keys and your address are together out there. Call us the same day: we rekey every affected cylinder, hand you fresh keys, and the old set becomes useless metal. It is one of the highest-value hours of locksmith work we do.
There is no schedule — there are events. Rekey when you move in, when a key is lost or stolen, when a roommate or relationship ends, when a contractor's access should end, and after any break-in attempt. Between those events, a well-made lock needs nothing but an occasional drop of lubricant.
We walk the home and count every keyed cylinder.
Pins swapped and cylinders rebuilt.
Every lock reinstalled and tested with the new keys.

Most NYC homes have 2–5 keyed cylinders, so a whole-house rekey typically takes under an hour on site.
For retiring old keys, yes — a rekeyed cylinder rejects every previous key completely. The only reason to change hardware instead is if the locks themselves are worn, damaged, or you want a security or style upgrade.
Yes. Without a working key we pick or shim the cylinder open first, then rekey it normally. It adds a small step but no new hardware is needed.
On events, not a schedule: moving in, lost or stolen keys, a departed roommate or contractor, or a break-in attempt. Outside those moments, a quality lock just needs occasional lubrication.
