Reliable Lost Your Car Keys

A mobile locksmith saves you the trip. For lost your car keys, the technician arrives with key blanks, cutting machines and dealer-level programming tools, explains what needs doing, and gives you the price before touching anything.

Quick Advice

  • Note where you are parked — a cross street or landmark helps us find you fast.
  • Have the year, make and model ready — it speeds up the quote.
  • Keep your ID and registration handy; we verify ownership before every job.

Built on Experience Since 2001

  • Local technicians who know Long Island roads and neighborhoods
  • Usually cheaper and faster than the dealer
  • Dealer-level programming equipment in every van
  • Weekends and holidays included, at the price we quote
  • Most makes and models covered, from basic keys to smart keys

Your Visit, Step by Step

  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. We answer any questions before the technician heads off.

Services Included

Depending on what you need, we handle:

  • Remote functions paired: lock, unlock, trunk and panic
  • The lost key erased from the car's memory where supported, so it can't start the car if someone finds it
  • Transponder chip or smart key programmed to your car's immobilizer so it actually starts
  • A new key originated from the VIN or by decoding your door lock — no original needed
  • A spare made at the same visit for much less than a second emergency call
  • Night, weekend and holiday calls, with the quote always given first

Across Long Island and Queens

Based in Hewlett, we cover Nassau County, much of Suffolk County and Queens. Check your town on our service area page.

What Affects the Price

Every job is quoted before a technician sets off — the price you hear is the price you pay. It depends on:

  • 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
  • The type of key: basic transponder, remote-head, flip key or push-to-start smart key
  • Whether you want spare keys made at the same visit

Ask for a quote any time at (516) 750-0433, day or night.
