These local details help confirm coverage and speed up dispatch accuracy.
Rekeying runs $95 to $300+ based on how many cylinders you have and how they're keyed. A single front door lock is the low end.
If you want every exterior lock, including a side or garage entry, keyed to one shared key, that's more cylinders and more labor, but it means one key for the whole house instead of a ring full of them. The technician quotes the exact number before scheduling, once they know your door count and current setup.
Sea Cliff's streets are hilly and narrow, laid out for a 19th-century summer resort, not modern parking. When you call, tell the dispatcher your street and whether there's a driveway or you're relying on street parking, that's passed to the technician so they can plan the approach before they arrive.
Typical arrival is 15 to 30 minutes from the call.
After you call (516) 636-1712, a local dispatcher takes your job and number, and the nearest available technician calls you back within a few minutes to quote the price. Have your address, the number of doors or locks you want rekeyed, and whether you want them all keyed alike ready for that call, it lets the technician quote accurately instead of estimating.
On original hardware, mentioning that upfront also helps them bring the right pins for older cylinder types.
