Licensed Locksmith — over 20 years experience, 2001–2026

Trusted in Nassau County since 2001 for transponder key programming — we bring the tools to your car.

Looking for transponder key programming? Car Key Locksmith handles transponder key programming — programming the chip inside your key so the car's immobilizer recognizes it and lets the engine start — anywhere in Nassau County, Long Island and Queens, 24 hours a day. Call (516) 750-0433 any time — a real person answers, day or night.

Toyota, Lexus, Honda and GM laser cut keys are cut on site, then programmed and tested with you. Below you will find what is included, how the visit works and what affects the price. Next door in Hicksville, Mill Neck and Inwood? The same technicians cover you.

Rooted in Nassau County

Car Key Locksmith is a local business, not a national call center. Since 2001 we have answered our own phones, quoted our own jobs and sent our own technicians.

Plenty has changed in the trade since 2001 — new keys, new locks, new technology. We have kept up with all of it, so you get current equipment and current know-how.

A Few Pointers

  • Stay with the vehicle if it is safe to do so.
  • Keep your ID and registration handy; we verify ownership before every job.
  • If a key breaks in the lock, leave the piece in and call us rather than digging at it.

Step by Step

Here is what happens, start to finish:

  1. Call (516) 750-0433 with the year, make and model and what is happening when you turn the key.
  2. We quote the job and confirm we carry the right transponder.
  3. On site we cut the key and program its chip to your car's immobilizer.
  4. We start the car with every key and test the remote functions before leaving.

Domestic, Asian and European Makes

From older basic metal keys to the latest push-to-start smart keys, we cut and program keys for Infiniti, Acura, Volkswagen, Volvo, Dodge and GMC and more. See our Toyota, Chrysler, Dodge, Jeep & Ram and Land Rover & Jaguar pages for brand details.

Frequently Asked Questions

I lost my car keys and have no spare. Can you help?

Yes. With your ID and the registration or title, we make a new key from the VIN and program it to the car — no original needed.

Do you work weekends and holidays?

Yes. We work every day of the year, and the price is always quoted before we come out. Call (516) 750-0433.

Do you repair ignitions?

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

Are your technicians licensed and insured?

Yes. We are a licensed locksmith in New York State, every technician is insured, and we verify ownership before every job.

Why does my car crank but not start with a new key?

The blade turns the ignition, but the transponder chip hasn't been programmed to the immobilizer. Programming the chip fixes it.

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.

Can any key be programmed to my car?

Only a transponder of the right type for your make and model. We carry the common types and can confirm before we come out.

What should I have ready when I call?

Your location, the year, make and model, and your ID with the registration or title for when the technician arrives.

Day or Night, We Answer

Our mobile technicians are available 24/7 for lockouts, lost keys and key fob programming.
