Install or replace a lock on a home door

Replacing a lock in an existing opening can be a different job from fitting a deadbolt where there has never been one. The door material, existing cutouts and space on the frame matter. A photo of the inside, outside and door edge helps identify the setup.

If the old lock catches only when the door is shut, mention that before choosing a replacement. The fit between the bolt and the frame can affect how the new hardware works. For an apartment, share any building requirements for the finish or lock type.

Lock Change vs. Rekeying

A lock change makes sense when the hardware is damaged or when you need a different lock or deadbolt. If the existing lock works and your goal is to stop old keys from working, check whether it can be rekeyed. For a replacement quote, tell us whether you already have the new hardware and whether the current door has an opening that fits it.

NYC locksmith pricing guide
Can I add a deadbolt to my apartment door?

Ask building management whether you can add a lock and which hardware they allow. Then share photos of the door and frame so we can check where a deadbolt would fit.

Can I supply the new lock?

Tell us the model and share photos of your door before booking. Fit depends on the measurements and on the existing opening.

Can I use the same key as another door?

That depends on the cylinders and keyway. Mention the other door so we can discuss compatible hardware or rekeying.
