How to Disable a Transponder Key

Transponder keys are a common convenience and safety feature used on vehicles around the world. These keys, also known as chip keys or ignition keys, are electronically synced to your engine. Once you have programmed it, you can only use a set key to start your car. While you can program the key directly from your driver's seat, you can also disable the keys in case you have lost one or do not wish to use the technology anymore.

Step 1 - Enter your car, and insert your key into the ignition.

Step 2 - Turn the key to "On," leave it there for 10 minutes and 30 seconds and then cycle it back "Off."

Step 3 - Repeat the previous step two more times, ending in the "Off" position after the third cycle. You can now enter the programming sequence with your key erased.

Remove the key from the ignition without turning the car on. This will close the programming sequence and leave your key disabled.
