Key Fob Replacement NYC — Programmed On-Site, Same Day
A dead or lost fob does not require a dealership appointment. Sunny Locksmith supplies, programs, and repairs key fobs at the curb across Manhattan, Brooklyn, and Queens — the same mobile setup we used this May in Bushwick to cut and program a full car key replacement on-site at Wyckoff Ave & Myrtle Ave (photos on our recent jobs page). Licensed NYC #2096389-DCA. Call (917) 495-1990.
First: Is the Fob Actually Dead?
A good chunk of "replace my fob" calls end up costing the client almost nothing, because the fob is not dead — the battery is, or the buttons wore out, or the shell cracked and the board inside is fine. We check before we sell you anything. Battery swaps and shell replacements take minutes; we move your existing electronics and cut the new shell's emergency blade to match your doors. If the board itself is fried, then it is a real replacement, and we do that on the spot too.
Replacing and Programming Fobs
Standard Remote Fobs
For remote-entry fobs we supply the fob, program it to your car through the OBD diagnostic port, and test lock, unlock, trunk, and panic before we leave. Domestic, European, and Asian brands. If you found a cheap fob online, we can usually program that too — with the honest warning that aftermarket boards fail more often than OEM ones.
Smart Proximity Fobs and Push-to-Start
Proximity fobs — the kind that stay in your pocket — carry the immobilizer chip, so programming them means pairing with the car's computer, not just the door remotes. We use the same class of diagnostic equipment dealers use. If you have lost every fob, that is an all-keys-lost job and still doable at the curb; see smart key replacement.
Erasing Lost and Stolen Fobs
When we program a replacement for a lost or stolen fob, we erase the old one from the vehicle's memory. Skipping this step means whoever holds your old fob can still unlock — and possibly start — your car. It takes minutes during programming and we do it by default, not as an add-on.
Fob Problems That Are Not Fob Problems
Fob works from two feet away but not twenty: weak battery or interference, rarely the fob. Car does not start but the fob unlocks the doors: often the ignition or the immobilizer antenna, not the fob — see ignition repair. Buttons work intermittently after a rainstorm or a washing machine ride: the board is corroding, and moving your key data to a new fob now is much cheaper than an all-keys-lost call after it dies completely.
Why On-Site Beats the Dealer for Fobs
Dealers typically order fobs rather than stocking them and want the car at their lot for programming. We carry common fobs in the van and program at your curb, your office garage, or wherever the car is parked — the same visit you called about. For spares: a second programmed fob made today is the best insurance in this business, because fob prices roughly double the moment you have zero working ones.

Frequently Asked Questions
Can you program a fob I bought online?
Usually yes, if it is the right part number for your vehicle — we verify compatibility before programming. Fair warning from experience: aftermarket boards fail more often than OEM. If yours cannot be programmed, we carry OEM-grade fobs on the van and quote before touching anything.
My fob stopped working suddenly — do I need a new one?
Maybe not. Dead batteries, worn buttons, and cracked shells account for a large share of "dead" fobs, and those are minutes-cheap fixes. We test the fob first and tell you what it actually needs; plenty of fob calls end with a battery and a working remote.
Do you handle push-to-start proximity fobs?
Yes — supply, programming, and all-keys-lost recovery for proximity systems, done at the car through the diagnostic port. We test lock, unlock, trunk, and engine start before leaving. Domestic, European, and Asian brands covered.
Should I get a spare fob programmed?
Emphatically yes. With one working fob, adding a spare is quick and moderately priced. With zero working fobs, the same result becomes an all-keys-lost procedure at roughly double the cost. A spare made today is the best money you will spend on this car.
