Lock Change in Great Neck Estates, NY

A single standard cylinder swap sits at the low end of $95 to $350+. Cost climbs with high-security cylinders, smart or electronic locks, multiple doors keyed alike, and older Tudor-style doors where the existing hardware is nonstandard and needs a compatible replacement rather than a straight swap.

Your technician confirms the exact number before starting, once they've seen the doors and lock types in person or over the phone.

Most of the village sits just off Middle Neck Road, which keeps arrival times in the 15 to 30 minute range once a technician is dispatched. Call the main line and a dispatcher logs the job and your number right away; the nearest available technician calls back within a few minutes to talk through which doors need new locks and quote a firm price before anyone heads over.

Have your keys or the current lock brand on hand if you know it, and decide ahead of time whether you want all doors keyed to a single key or kept separate, since that changes the cylinder count and the price. If it's a shared or multi-unit property, let the dispatcher know who has authority to approve the work when they take your call, so there's no delay once the technician is on site.
