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.

Out on the East End, the nearest dealership can be a long drive away and towing a car there costs time and money. We bring dealership-level key cutting and programming equipment to Peconic, which matters most for seasonal residents, beachgoers and anyone who discovers a missing key far from home.

Neighbors in Cutchogue, Southold and New Suffolk use us too — Peconic is right on our way.

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

• 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

Call (516) 750-0433 for an exact quote — it takes a minute. There are no hidden call-out fees: what we quote is what you pay.

• Everything tested before we leave — doors, ignition, trunk and remote buttons
• An arrival window on the first call, so you are not left guessing
• Usually cheaper and faster than the dealer
• Dealer-level programming equipment in every van
• Upfront pricing — you get the price before we dispatch, with no surprise fees on arrival

• Keys tested in the doors, ignition and trunk before we leave
• The lost key erased from the car's memory where supported, so it can't start the car if someone finds it
• Honest advice on repairing versus replacing
• Remote functions paired: lock, unlock, trunk and panic
• 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

Licensed, insured and local since 2001. Car Key Locksmith has grown by word of mouth among drivers who wanted honest prices and work done right the first time.

Decades of car key calls have taught us to come prepared. Before we set off, we ask the right questions, so the technician arrives with what the job needs.

• Replace key fob batteries every couple of years, before they fail.
• Test the remote buttons and the trunk with the technician before we leave.
• If a key breaks in the lock, leave the piece in and call us rather than digging at it.
