Lock Change in Old Bethpage, NY

A basic single-cylinder swap sits at the low end of the $95 to $350+ range; the cost climbs with higher-security cylinders, matching multiple doors to one keyway, or replacing deadbolts alongside knob locks. Most Old Bethpage jobs are single-family homes, so it's common to price out front and back doors together in one visit, and rekeying to a shared keyway if you want one key for every lock.

Your technician gives you the exact number by phone once they know what's on your doors, before you agree to anything.

Old Bethpage is car-dependent with no LIRR station in the hamlet, so nearly every call here is a drive-up to a house off Round Swamp Road, Old Country Road, Bethpage-Sweet Hollow Road, or reachable via the Long Island Expressway. The dispatcher passes your job to whichever local technician is closest, and that tech calls you back within a few minutes to confirm the address and quote before heading over, landing most visits in the 15 to 30 minute window.

Know which doors need new locks and whether you want them keyed alike, since that changes both price and install time. If you have a preference for keyway type or brand, mention it on the callback so the technician arrives with the right hardware rather than making a second trip.

Someone should be home to let the technician in and confirm the work once it's done.
