Smart Key Replacement NYC — Push-to-Start Fobs
Push-to-start cars need proximity fobs paired with the immobilizer — a cut metal key alone will not start the engine. Sunny Locksmith supplies and programs smart keys at the curb across NYC, same mobile diagnostic setup as the May all-keys-lost job at Wyckoff Ave & Myrtle Ave in Bushwick. Licensed NYC #2096389-DCA. Call (917) 495-1990.

Smart Keys vs. Regular Remotes
A smart key lives in your pocket; the car detects it and lets you push a button to start. Inside the fob is a transponder chip the immobilizer must recognize — programming pairs that chip with your car's computer and syncs lock, unlock, and trunk functions. Dealer quotes often assume a tow; we do it where the car sits.
All Keys Lost — Still Doable
Zero working smart keys is the expensive scenario, but it is not a tow scenario. We pull what we need from the vehicle, program a new fob through the OBD port, and cut the emergency blade. That was the Bushwick job in May: no working key, driving the same visit. See car key replacement.
Adding a Spare Smart Key
With one working fob, a spare is moderate cost and one short visit. With no fobs, the same result costs roughly double — the economics argue hard for making the spare today.
Erasing Stolen Keys From Memory
When we replace a lost smart key, we delete the old one from the immobilizer so it cannot start the car even if someone finds it. Same for fob programming on remote-only systems. Ask any locksmith programming your car to confirm they erase — we do it by default.
When It Is Not the Smart Key
Car unlocks but will not start: could be immobilizer antenna, not the fob. Key turns but sticks: ignition repair territory. We triage honestly — see automotive locksmith for the full scope.

Frequently Asked Questions
Can you replace a smart key without towing to the dealer?
Yes — we program at the car through the diagnostic port. The Bushwick replacement in May was all-keys-lost, no tow, same-day drive home.
How much does a smart key replacement cost?
Depends on make, model, and year — exotic and luxury brands cost more. Call with those three details for a real phone quote, not a bait number.
Should I get a spare smart key now?
Yes. With one working fob, a spare is quick and moderate cost. With zero fobs, you pay the all-keys-lost premium — best money you will spend is a spare made today.
My smart key was stolen — will the old one still start the car?
It can, until someone erases it during programming. When we program your replacement we delete the stolen key from memory by default.
