Need a new transponder chip key for your car? Our mobile auto locksmith team cuts and programs transponder keys on site in Fort Worth for most makes and models — same day, no tow, no dealer wait.
A transponder key is a car key with a small chip embedded in the plastic head. When you put the key in the ignition, the chip sends a unique digital code to the vehicle's immobilizer. The car only starts if the code matches what the immobilizer expects. This is what prevents a stolen or copied blade from being able to start a modern vehicle — and it's why a hardware-store key cut alone will turn the lock but not start the engine.
Almost every gas-powered car sold in the United States since the late 1990s uses a transponder key, a remote head transponder key, or a smart proximity fob. If your key has a thicker plastic head than an old-style metal key, it almost certainly contains a chip.
A transponder key has a small chip in the plastic head that sends a unique signal to your car's immobilizer. The vehicle only starts when the chip's code matches the one programmed into the car — that's what stops a copied blade from starting most modern cars.
Yes. A qualified mobile auto locksmith can cut and program transponder keys on site for most makes and models, including all-keys-lost situations.
A hardware-store cut may turn the lock or open the door, but it will not start a vehicle that uses a transponder system. The chip in the key has to be programmed to your specific car.
Cost depends on the vehicle make, model year, and key type. Standard transponder keys are usually less than smart proximity fobs. We share the relevant service details upfront before any work begins.
