A local technician typically reaches you in 15 to 30 minutes and quotes a firm price by phone before heading out. Pricing runs $145-$395+ depending on make, model, and key type. Call (516) 636-1712.

These local details help confirm coverage and speed up dispatch accuracy.
Transponder programming runs $145-$395+, and the spread comes down to your vehicle and key type: a basic chip key for an older sedan costs less than an all-keys-lost job on a newer model that needs a key cut and programmed from scratch, or a proximity/smart key. The dispatcher passes your make, model, and year to the technician, who calls back with a real number based on what your car actually needs before anything is scheduled.
Seaford is cut through east-west by Sunrise Highway (NY 27), and technicians use that plus Wantagh State Parkway and the Seaford-Oyster Bay Expressway to move quickly between the waterfront streets of Seaford Harbor, the Seaford Manor side, and the area around Seaford LIRR station. Typical arrival is 15 to 30 minutes from the call.
If you're at the station lot, a canal-front driveway, or anywhere parking is tight, mention it when the technician calls back so they know what to expect on arrival.
Have your car's make, model, and year on hand, along with your exact location (an address, cross street, or a landmark like the Tackapausha Preserve if you're not sure of the street). You'll also need to show proof of ownership, such as a registration or ID matching the vehicle, since a technician won't program a key to a car without it.
If you have a spare key already, mention that too, since it can change the job.
