Reliable Lost Car Keys How To Replace

Car Key Locksmith has been cutting keys and opening cars in Nassau County since 2001. Lost Car Key Replacement — making a brand-new working key when every key is gone — even with no spare and no original to copy — is one of the most common calls we get, and our technicians handle it at your car, usually in a single visit.

Upfront Pricing

We quote every job upfront on the phone, so you know the price before anyone is dispatched. What the price depends on:

  • Whether the car needs its immobilizer module accessed to program an all-keys-lost key
  • The make — some European systems take extra equipment and time
  • Whether you want spare keys made at the same visit
  • The type of key: basic transponder, remote-head, flip key or push-to-start smart key

More Services

  • Honda laser cut keys and Acura keys cut and programmed
  • Commercial door lockouts for offices and storefronts
  • GM GDS2 dealer tool programming for late-model Chevrolet, GMC, Buick and Cadillac
  • Licensed locksmith in New York State, fully insured
  • Laser cut key duplication — high-security sidewinder keys cut on our laser key machine

Our Promise

  • Most makes and models covered, from basic keys to smart keys
  • Usually cheaper and faster than the dealer
  • Weekends and holidays included, at the price we quote
  • An arrival window on the first call, so you are not left guessing
  • Upfront pricing — you get the price before we dispatch, with no surprise fees on arrival
  • We come to you — no tow, no dealership appointment, no waiting days for parts

How Booking Works

Here is what happens, start to finish:

  1. Call (516) 750-0433 with your location, the year, make and model, and whether any key still exists.
  2. We quote the job and give you an arrival window.
  3. On site we verify ownership, then cut the new key and program it to the car.
  4. We erase the lost keys from the car's memory where possible and test everything with you.

Frequently Asked Questions

Will my lost key still start the car?

Not after we are done, where the car supports it: we erase lost keys from the immobilizer memory so only the keys you have will start it.

Can you make a spare key at the same visit?

Yes, and it is the best time to do it — a spare made now costs far less than an emergency replacement later.

Can you make a key if I have no spare at all?

Yes. With your ID and registration we originate a key from the VIN or by decoding the lock, then program it to your car — no original key needed.

Can you cut laser cut keys?

Yes. We cut laser cut (sidewinder) keys on site, including Honda, Acura, GM, Toyota and Lexus laser cut keys, and program them to the car.

Which areas do you cover?

All of Nassau County, much of Suffolk County and Queens, including JFK Airport, Jones Beach, Resorts World Casino and UBS Arena.

Do you repair ignitions?

Yes — ignition repair and replacement, including Honda and Acura ignitions that wear out and stop turning.

How much will it cost?

It depends on the vehicle and the key or lock involved. Call (516) 750-0433 with the year, make and model and we give you the exact price before we dispatch.

How long have you been in business?

Since 2001. Car Key Locksmith is based in Hewlett, NY, and has served drivers across Long Island and Queens for more than two decades.

Is it cheaper than the dealer?

Usually, yes — and there is no tow, no parts order and no waiting days for an appointment. We give you the price before we come out.

Ford FDRS and GM GDS2 programming for newer vehicles, right where you are parked.
