Mobile Locksmith Lost Car Keys Without the Wait

Every car is a little different, so we ask a few questions before we come out. That way the technician arrives with the right parts for making a brand-new working key when every key is gone — even with no spare and no original to copy, and the job is usually finished in one visit.

If you are closer to Woodbury, Great Neck and Port Washington, we come there too — same price, same service.

From Your Call to a Finished Job

  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.

The Price Comes First

We quote every job upfront on the phone, so you know the price before anyone is dispatched. What the price depends on:

  • 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
  • The make — some European systems take extra equipment and time

Compared with the dealer, most drivers save both money and time — and skip the tow.

Serving Nassau County & Queens

We work across Nassau County — Lawrence, Valley Stream, Glen Head and Westbury and many more — as well as much of Suffolk County and Queens. See the full service area.

Keys for Most Vehicles

We stock blanks, remotes and smart keys for Subaru, Audi, Volkswagen, Infiniti, Jaguar, Honda, Ford and Mazda. If your vehicle uses proximity fobs, remote-head keys, push-to-start smart keys, basic metal keys and transponder chip keys, we can usually make it on the spot. See our Toyota, Chrysler, Dodge, Jeep & Ram and Land Rover & Jaguar pages for brand details.
