Quick answer
Yes. RC Locksmith Nassau County rekeys existing locks in Lynbrook, typically arriving in 15 to 30 minutes. Your hardware stays in place, only the pins inside change, so old keys stop working while your doors keep their current look. Pricing runs $95 to $300+ depending on how many cylinders you need done and whether you want them all set to one key. Call (516) 636-1712 for a quote before scheduling.
Rekeying resets the pins inside your existing lock cylinders so any old keys, whether lost, stolen, or held by a former tenant or roommate, no longer open the door. The hardware itself does not change.
It costs less than replacing locks and works on most standard residential cylinders.

These local details help confirm coverage and speed up dispatch accuracy.
A single-cylinder rekey starts around $95. Cost climbs with the number of cylinders on the property and whether you want them all keyed alike so one key works on every door, front, side, garage entry.
Moving in after a previous owner or tenant, ending a roommate situation, or replacing a lost key without buying new locks are the most common reasons people call. The technician confirms the exact price by phone once you describe how many locks and what brand, before any work starts.
The dispatcher takes your job and number, and the nearest technician calls back within a few minutes with a price based on what you describe. Typical arrival in Lynbrook runs 15 to 30 minutes.
If you're near Five Corners or downtown along Atlantic Avenue, street parking can be tight during business hours, so having a spot or driveway access ready speeds things up. For homes off Merrick Road, Hempstead Avenue, or Peninsula Boulevard, a cross street or house number visible from the road helps the technician find you faster.
Have the keys you want to keep working set aside, and know roughly how many exterior locks need rekeying, front door, back door, garage. If you want all locks keyed to a single key, mention that when you call so the technician brings the right setup.
Confirm the price on the callback before the visit is scheduled. RC Locksmith has dispatched technicians across Nassau County since 2009, so the person coming to Lynbrook knows the area rather than reading off a script.
