Quick answer
Yes. RC Locksmith Nassau County rekeys house and business locks in Oceanside, typically arriving in 15 to 30 minutes. We work with the hardware already on your doors, no replacement needed, and any old keys stop opening the locks the moment we finish. Pricing runs $95 to $300+ depending on how many cylinders you have and how you want them keyed. Call (516) 636-1712 for a price before anyone is scheduled.
Rekeying swaps the pins inside your existing lock cylinders so old keys, whether lost, stolen, or held by a past tenant or contractor, no longer open the door. The hardware itself stays put.
This works for a single door or a whole house keyed to one new key, and it's usually faster and cheaper than replacing locks outright.

These local details help confirm coverage and speed up dispatch accuracy.
Most rekey calls in Oceanside are homeowners who moved into a house with unknown key history, split-level and colonial houses often have a front door, side door, and garage entry that were never keyed alike. We can rekey all of them to a single new key in one visit, front door, back door, garage entry, whatever's on the house.
Price depends on the number of cylinders and whether you want them keyed alike or kept separate: $95 to $300+ covers the range from a single lock up to a full house set. If you're near the canals and have a dock-side entry or gate lock added on, mention it when the technician calls back so it's priced with everything else.
Dispatch sends the closest available technician, so a call from off Long Beach Road, Oceanside Road, Atlantic Avenue, Lawson Boulevard, or Weidner Avenue typically gets a tech on site in 15 to 30 minutes. The dispatcher who answers isn't the person who shows up, they log the job and your number, and the nearest tech calls you back within a few minutes with an actual price based on your lock count and setup before anything is scheduled.
If your address is easiest to find relative to a cross street or landmark, like the LIRR station area or a specific block off Long Beach Road, pass that along on the callback so the tech isn't guessing at the door.
Have all doors you want rekeyed unlocked and accessible, and know roughly how many exterior locks are involved, since that's what determines where in the $95 to $300+ range your job lands. If you want every lock on the same key, say so on the callback so the technician brings the right pin sets.
No need for old keys to be present, if they're lost that's exactly what rekeying solves. We're a local outfit that's been dispatching technicians around Nassau County since 2009, not a national number that resells your job to whoever's cheapest that day.
