Lock Change & Key Duplication in Westchester County

Lock change service for homes and businesses

A lock change is the clean-slate option: the old hardware comes off, new locks go on, and only your keys work. It is the right call after moving into a new home, when a tenant or employee leaves on bad terms, after a break-in, or when a lock is simply worn out and grinding every time you turn the key.

I carry deadbolts, knob sets, and lever handles from trusted brands like Schlage, Kwikset, Yale, and Medeco on the van, so you choose the right hardware on the spot without a hardware store run. Every install includes aligning the new lock, anchoring the strike plate with long screws for kick resistance, and keying every exterior door alike if you want one key for the whole house. For a deeper dive into the residential side, see my residential lock change service; for storefronts and offices, start with commercial locks installation or commercial lock rekeying.

Key duplication near you, without the line

Searching for key duplication near me in Westchester usually ends at a big-box kiosk that cannot copy half the keys people actually carry. I do it differently: the van comes to you, and the duplicates are cut on professional equipment while you watch. House keys, office keys, mailbox and cabinet keys, and restricted profiles that kiosks refuse are all handled on site.

Car keys are their own world of transponder chips and remote fobs, and I cover those too: cutting and programming spares for many makes and models through my car key duplication service. And if you have no working key at all, do not worry, a key can usually be made from the lock itself. I explain how in can a locksmith make a key without the original?

• Full lock change with quality hardware brought to you

Frequently asked questions

Do you cut house keys on site?

Yes. The van carries blanks and cutting equipment for common residential and commercial keys, so duplicates are made at your door, at home or at your business, anywhere in Westchester County.

Can you make a key if I do not have the original?

Usually, yes. A key can often be made from the lock itself even when every copy is gone. For cars, I cut and program replacement keys and fobs on site for many makes and models.

Should I change my locks or just rekey them?

If the hardware is in good shape and you only need old keys to stop working, rekeying is faster and cheaper. If locks are worn, damaged, or you want an upgrade, a full lock change makes more sense. I will tell you honestly which one your doors need.

How fast can you get to me for a lock change or spare key?

Dispatch is from Elmsford in central Westchester, so most of the county is reached in 15 to 35 minutes during business hours. When you call, I confirm an ETA before heading out.

How much does a lock change or key duplication cost?

You get an upfront, flat-rate quote before any work begins, based on the number of locks or keys and the hardware involved. See my pricing page for typical rates.
