Transponder Key Replacement

Every car key made since roughly the late 1990s has a transponder chip inside the plastic head, and the engine will not start unless the car's immobilizer recognizes that specific chip, which is why a $5 hardware-store copy of a modern car key turns the ignition but goes nowhere. SwiftLocksmith replaces lost, broken and stolen transponder keys on-site anywhere in NYC: we cut the new blade, then program the chip to your vehicle's immobilizer with professional diagnostic equipment, right at the curb.

The scenario we solve most is all keys lost. The situation where a dealership would have you tow the car and wait days for a key. We come to the car instead, originate a new key from the vehicle itself, and program it on the spot; in most cases you're driving the same day. We also program spare keys (dramatically cheaper than a dealer, and having a working spare is what makes a future all-keys-lost a non-event), replace snapped key blades while reusing your chip, and handle remote-head keys and fobs for most major brands. When you call, have your VIN and proof of ownership ready. We verify both before originating any car key, which protects you as the owner.

Transponder replacement typically runs $125 to $350 depending on the vehicle and key type, genuine transponder keys only, available daily from 8 AM to 8 PM. One honest limitation, stated up front: we do not currently service German or UK vehicles: BMW, Mercedes, Audi, Volkswagen, Mini and Land Rover use dealer-locked security architectures we've chosen not to work on rather than do a halfway job.
