All keys lost means you have no key at all, not even a spare, so the car has to be identified, a blank cut to match, and a new key programmed to the vehicle's immobilizer before it will start. That work happens at your car wherever it's parked in Oyster Bay.

Losing your only key is a different job from cutting a duplicate: we have to confirm the exact make, model, and year, cut a blank to match your ignition or door lock, and program that key to the car's immobilizer system from scratch, with no old key to clone from. That's why the range runs $195 to $495 or more.
Newer vehicles with proximity fobs or push-button start generally need more complex programming than older cars with a standard blade key, which is the main thing that moves the price up or down. The technician who calls you back will have your car's year and trim in mind and quote a real number before driving out, not a guess that changes once they arrive.
Oyster Bay's downtown sits in a tight grid along Main Street running toward the harbor, with South Street (NY Route 106), West Shore Road, and Berry Hill Road as the main ways in and out. Call (516) 636-1712 and a dispatcher takes your location and vehicle details, then the nearest technician calls you back within a few minutes to confirm the job and price before heading out, typically arriving in 15 to 30 minutes.
If you're parked near the LIRR station, the harbor, or a spot without a clear street address, mention a cross street or a visible landmark when you call back so the technician can find your car without circling the block.
Have your vehicle's registration or another form of proof that the car is yours on hand, since a locksmith needs to confirm ownership before cutting a key with no original to match against. Know where the car is parked, whether that's a driveway on one of Oyster Bay's older streets, a lot near the harbor, or a spot downtown, and be reachable at the number you called from so the technician can call ahead.
Once the technician arrives, cutting and programming the new key is done at the car itself, so there's no need to have it towed anywhere.
