Professional Lost Car Key Replacement Open Now

People call us for lost car key replacement open now for all sorts of reasons — a lost key, a broken fob, a car that won't start. Whatever the reason, lost car key replacement means making a brand-new working key when every key is gone — even with no spare and no original to copy, done properly at your car.

Next door in Jericho and Kings Point? The same technicians cover you.

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.

Mobile Service, Island-Wide

We work across Nassau County — Baldwin, Old Westbury, Valley Stream, Syosset and Old Bethpage and many more — as well as much of Suffolk County and Queens. See the full service area.

Trusted Since 2001

From our base in Hewlett, NY, we have served Nassau County since 2001. Many of our customers found us in an emergency and kept our number for the next time.

Covered on Every Call

Here is what we do on site:

  • A new key originated from the VIN or by decoding your door lock — no original needed
  • Most makes and models, from basic metal keys to push-to-start smart keys
  • Night, weekend and holiday calls, with the quote always given first
  • Remote buttons paired — lock, unlock, trunk and panic
  • 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

More Ways We Can Help

While we are there, we can also help with:

  • 24 hour lockout service for cars, SUVs, trucks and vans, nights and weekends included
  • Laser cut key duplication — high-security sidewinder keys cut on our laser key machine
  • Toyota remote head repair and key fob shell replacement
  • Home and house lockouts too — we open front doors and change locks

Reasons to Call Us

  • Licensed, insured technicians you can trust
  • Dealer-level programming equipment in every van
  • Everything tested before we leave — doors, ignition, trunk and remote buttons
  • Most makes and models covered, from basic keys to smart keys
  • No high-pressure upsells — we quote only what you need

Helpful Tips

  • If a key breaks in the lock, leave the piece in and call us rather than digging at it.
  • Get a spare made while you still have a working key — it costs far less than an all-keys-lost call.
  • Replace key fob batteries every couple of years, before they fail.
  • Keep your ID and registration handy; we verify ownership before every job.

Getting a Quote

No two jobs are identical, which is why we quote each one on the phone first. The main factors:

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

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

Keys for Most Vehicles

Honda, Infiniti, Volvo, Chevrolet, Dodge, Lexus and BMW — these are the makes we see every week, and our vans are stocked for them. Key types include flip keys, push-to-start smart keys, basic metal keys, remote-head keys and proximity fobs. See our Toyota, Chrysler, Dodge, Jeep & Ram and Land Rover & Jaguar pages for brand details.

Frequently Asked Questions

How long does it take?

Most key replacements and programming jobs are finished within an hour of arrival. We tell you what to expect when you call.

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.

Can you do lost car key replacement open now on site?

Yes. We are fully mobile and come to your car, so there is no towing involved.

Which areas do you cover?

All of Nassau County, much of Suffolk County and Queens, including JFK Airport, Jones Beach, Resorts World Casino and UBS Arena.

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.

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.
