Lost Car Key Green Flag You Can Count On

When you call about lost car key green flag, a real person answers, asks a few quick questions and gives you a price. Then a technician heads to your car with key blanks, cutting machines and dealer-level programming tools.

Most jobs are finished within an hour of arrival.

We are just as busy in nearby Lawrence, Levittown and Bayville.

Lost Car Key Green Flag Pricing

A few things decide the final figure:

  • 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
  • Whether the car needs its immobilizer module accessed to program an all-keys-lost key

If anything changes once we see the job, we tell you before doing it.

Where Our Vans Go

Our coverage runs from Mineola, Old Westbury, Port Washington and East Meadow out across Long Island and into Queens. Not sure if we reach you? Call (516) 750-0433.

Services Included

Here is what we do on site:

  • Remote functions paired: lock, unlock, trunk and panic
  • A new key originated from the VIN or by decoding your door lock — no original needed
  • Ownership checked with ID and registration, for your protection
  • The lost key erased from the car's memory where supported, so it can't start the car if someone finds it

Step by Step

It usually takes just a few steps:

  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.
  5. If you need anything else later, the same number reaches us day or night.

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 offer lost car key green flag 24/7?

Yes. Our 24 Hour Emergency line is answered day and night, including holidays. Call (516) 750-0433.

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.

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.

Do I need to bring the car to you?

No. We are a mobile locksmith: the technician comes to your car at home, at work or at the roadside.

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.
