How to Bypass a Transponder Key

135

A transponder key emits a unique radio frequency that lets your ignition know that the proper key has been inserted into the car. This adds a layer of security to your car and deters hot wiring. Most transponder keys are electronically coded with a secure frequency specific to your car, meaning that they usually can be programmed only by an automotive locksmith or your dealership. More often than not, this makes them expensive to replace. If you would like to bypass your transponder key every time you start your vehicle or are installing a remote starter, consider bypassing the ignition security.

Step 1

Take your transponder key and place the plastic head in a pair of pliers. Gently grasp the pliers and work off the key head.
