Lost Car Keys Insurance Cover From a Mobile Locksmith
Lost Car Key Replacement is handled by the same licensed technicians who have served Nassau County since 2001. They check ownership, do the work at your car, and leave only when everything works.
Drivers in Valley Stream and Glen Head have called us for years.
What's Included
What you can expect:
- The lost key erased from the car's memory where supported, so it can't start the car if someone finds it
- A new key originated from the VIN or by decoding your door lock — no original needed
- Remote functions paired: lock, unlock, trunk and panic
- A spare made at the same visit for much less than a second emergency call
- Transponder chip or smart key programmed to your car's immobilizer so it actually starts
- Ownership checked with ID and registration, for your protection

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.
Is it cheaper than the dealer?
Usually, yes — and faster, because there is no tow, no parts order and no appointment. You get the price before we come out.
Can you do lost car keys insurance cover on site?
Yes. We are fully mobile and come to your car, so there is no towing involved.

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