Lock Change in Old Westbury, NY

A single exterior cylinder swap sits at the low end of the $95 to $350+ range, but Old Westbury properties frequently need more: matching keyways across a main house, guest house, and detached garage, upgrading to a higher-security cylinder, or re-keying everything to one master key after a purchase or tenant change. Tell the dispatcher how many doors and what type of locks you're dealing with when you call, since that's what determines whether the callback quote lands near the low or high end.

With no LIRR stop in the village and most homes set well back on one- to four-acre lots, the technician needs clear directions to find the right gate or driveway, not just the street address. When the callback comes, mention any keypad or intercom entry, gate codes, or which of several structures needs the lock changed.

The 15 to 30 minute response window assumes the technician can get to your door without circling a long private drive looking for the entrance.

Photos of the current lock or door hardware help the technician bring the right cylinders and avoid a second trip, especially if your locks are an older or less common keyway. Also have proof you own or lease the property on hand, since a locksmith installing new locks on a residence needs to confirm you have the right to authorize the work.

RC Locksmith Nassau County has dispatched local technicians to Nassau County jobs since 2009, so the person who calls you back knows the area and quotes a real price before scheduling, not a national call center reading from a script.
