Quick answer
Yes. RC Locksmith Nassau County rekeys locks at homes and estate properties in Muttontown, with a technician typically reaching you in 15 to 30 minutes. Your existing hardware stays in place, only the internal pins change, so old keys stop working and new ones are cut on the spot. Pricing runs $95 to $300+ depending on how many cylinders you need rekeyed and whether you want them all set to one key. Call (516) 636-1712 for a quote before anyone is scheduled.
Rekeying resets the pins inside your existing locks so any old keys, whether from a past owner, a contractor, or a lost set, no longer open them. It costs less than swapping out hardware and takes one visit.

These local details help confirm coverage and speed up dispatch accuracy.
Muttontown properties tend to have more entry points than a typical house, main house doors, guest houses, garages, gates, sometimes barns or outbuildings on equestrian parcels, and each cylinder rekeyed adds to the job. The $95 to $300+ range reflects that: a single front door lock sits at the low end, while a full estate property with multiple structures and a request to have every lock take the same key sits higher.
Tell the callback technician how many doors and what kind of locks you have (standard cylinders, high-security, smart-lock cores) so the quote is accurate before they arrive, not adjusted on site.
Muttontown has no LIRR station and is fully car-dependent, and properties here often sit back from the road on large, gated, or wooded lots off NY 106, NY 25A, or Muttontown Road, unlike a tight village grid. When you call, the dispatcher takes your job and number and the nearest available technician calls back within a few minutes to quote a price; that callback is also when you should give them the actual entrance to use, since a long driveway or a gate code matters more here than a street address.
Expect a 15 to 30 minute arrival once the visit is scheduled.
Have a photo or the brand of your current lock cylinders ready if you can, it speeds up the phone quote, and decide in advance whether you want all doors keyed alike or kept separate, since that's a setup decision, not something to change mid-job. If any gate, keypad, or intercom controls access to the property, make sure it's set to let the technician in or have someone available to buzz them through.
Confirm the callback price before work starts; it's quoted before scheduling, not adjusted after arrival.
