Transponder key replacement covers vehicles that use an older-style chip key: the key is cut to open the doors and ignition, and a small transponder chip inside the plastic head is read by the immobilizer to allow the engine to start.
Who Needs This Service?
- Owners of vehicles with a chip built into the key's plastic head rather than a full smart fob
- Drivers whose transponder key was lost, stolen, or damaged
- Anyone told by a hardware store their car needs a chip key, not a plain cut
- Owners buying a used transponder-equipped vehicle with only one key
- Drivers whose key still turns the ignition but the chip has failed inside

- Identification of your vehicle's correct transponder chip type

What This Service Costs
Transponder keys cost more than a plain mechanical key because of the chip and the pairing step, and pricing shifts depending on which chip type your vehicle uses. Some are common and inexpensive, others are less common and cost more to source.
We identify the exact chip your car takes before quoting, so the price we give matches the part actually going into the key.
Cut Key Plus Chip, Two Jobs in One
A transponder key does two separate jobs. The cut portion is a mechanical match to your locks, letting you turn the ignition and open the doors. The chip inside the head is a completely separate radio component the immobilizer reads before it allows starting.
We handle both in the same visit: cut the blank to match your locks, then fit and program the correct transponder chip so the finished key does both jobs at once.
When the Chip Fails But the Key Still Cuts
Sometimes the mechanical cut of a key is fine but the internal chip has cracked or died, usually after years of use or being dropped repeatedly. In that case, only the chip side needs attention, and it's a quicker fix than starting from scratch.
If the key is lost entirely or badly worn, full replacement covering the cut and the chip is the more reliable path, since there's nothing usable left to build from.

Transponder chips vary by manufacturer and model year, so knowing which chip your car actually needs matters. We identify it before ordering or cutting anything, which avoids a mismatched key that won't start the car.
As with every vehicle job, we confirm you own the car or have a right to it first. It's a small step that keeps a bad actor from getting a working key to a car that isn't theirs.
