Locksmith Since 2001
Experience is what turns a long job into a quick one. Since 2001, our technicians have handled lost car key replacement for drivers all over Nassau County, and it shows in how smoothly the work goes.
Upfront Pricing
Here is what moves the price up or down:
- Whether the car needs its immobilizer module accessed to program an all-keys-lost key
- 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
Compared with the dealer, most drivers save both money and time — and skip the tow. Call (516) 750-0433 with your year, make and model for an exact quote. It is usually less than the dealer, and there is no tow to pay for.
What's Included
Our technicians can take care of:
- A new key originated from the VIN or by decoding your door lock — no original needed
- Transponder chip or smart key programmed to your car's immobilizer so it actually starts
- The lost key erased from the car's memory where supported, so it can't start the car if someone finds it
- Remote functions paired: lock, unlock, trunk and panic
- Ownership checked with ID and registration, for your protection
- A spare made at the same visit for much less than a second emergency call

Frequently Asked Questions
Do you have dealer programming tools?
Yes. We use dealer-level software, including Ford FDRS and GM GDS2, to program keys on newer Ford and GM vehicles that generic tools can't reach.
Do you work on all makes and models?
We carry keys and programming for most cars, SUVs, vans and pickups. Call with the year, make and model and we confirm right away.
Do you repair remote head keys?
Yes. Honda and Toyota remote head repair is one of our most common jobs — a new shell, buttons or blade often costs far less than a new key.
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.
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.
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.
