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. Because we are fully mobile, the work happens wherever your car is — at home, at work, in a parking lot or at the roadside.

We start by confirming you own the vehicle, then do the job with professional tools and test everything with you before we leave. If something else turns up — a worn ignition or a fob with a dead battery — we tell you and quote it before doing anything.

Not in Port Jefferson? We also serve Miller Place, East Setauket and Port Jefferson Station.

On the North Shore, cars spend their days in long private driveways, harbor and beach lots, and train station parking. In Port Jefferson we routinely make new keys right in the driveway, so the vehicle never has to be towed to a dealership, and we work on the premium European and Japanese models that dealers often take days to key.

A few things decide the final figure:

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

Ask for a quote any time at (516) 750-0433, day or night. We would rather give you an honest number on the phone than surprise you on arrival.

Our technicians can take care of:

• A new key originated from the VIN or by decoding your door lock — no original needed
• Cars, SUVs, vans and pickups — we come to all of them
• Remote functions paired: lock, unlock, trunk and panic
• Ownership checked with ID and registration, for your protection
• Transponder chip or smart key programmed to your car's immobilizer so it actually starts
• A spare made at the same visit for much less than a second emergency call
• The lost key erased from the car's memory where supported, so it can't start the car if someone finds it
