Emergency Lost Car Key Replacement Pricing
A few things decide the final figure:
- The type of key: basic transponder, remote-head, flip key or push-to-start smart key
- The make — some European systems take extra equipment and time
- Whether the car needs its immobilizer module accessed to program an all-keys-lost key
What We Do On Site
Typical work on these calls includes:
- 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
- Most makes and models, from basic metal keys to push-to-start smart keys
- Keys tested in the doors, ignition and trunk before we leave
- A new key originated from the VIN or by decoding your door lock — no original needed
- Cars, SUVs, vans and pickups — we come to all of them

Frequently Asked Questions
How fast can you get to me?
Most calls are reached within the hour. We give you an arrival window when you call.
What if I have lost every key and have no spare?
We can still make a new key. With your ID and the registration or title, we originate a key from the VIN or the locks and program it to the car.
Do you offer 24 hour lockout service?
Yes. Car lockouts and auto lockouts are handled 24 hours a day, every day of the year. Call (516) 750-0433.
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.
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.
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.
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.
