A lot of individuals in Dallas are still puzzled about what a transponder key is and how it works. Simply put, these keys have a radio frequency transmitter inside of them. A device near the ignition switch of the vehicle has a receiver. The key transmits an extremely low-level signal that the vehicle can detect only when the key is in the switch. 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. Transponder keys have become a popular technology in cars all around the world. These keys are used to electronically sync to your engine, and once programmed, only a transponder key can be used to start your car. You can replace a lost or disabled transponder key yourself in just a few minutes by reprogramming it. The programming sequence is completed from the driver’s seat and will have your remote ready to use right away.
Acquire a new cut key from the dealership or the installer of your transponder transmitter system and have two previously programmed keys ready.
Insert the first programmed key into your car’s ignition and turn it to the “On” position.
Turn the key back “Off” and insert the second programmed key within five seconds.
Turn this second key “On” and the back “Off” and remove the key from the ignition.
Insert the new key within ten seconds, turn it “On” for one second, and then cycle it back “Off.”
Wait for the security light to turn on within the car, wait for the light to stay on for three seconds, and remove your key from the ignition to complete the process and have your replacement key ready to use.
If you want to use a remote starter, take your transponder key and place the plastic head in a pair of pliers. Gently grasp the pliers and work off the key head. If it will not slip off easily, grasp the metal end of the key with the flat surface of the other pliers, and gently pull in opposite directions until the head slips off. Do not pull with the pliers by grasping the key’s teeth; you will compromise the key’s ability to turn the tumblers in your ignition.
Place the key’s head near the ignition with the hot glue gun. Squeeze a quarter-sized dab on the underside of the steering column, as close to the ignition as you can get, and press the key head into the glue until it sets.
Test the ignition with the key to turn it over. The transponder’s proximity to the ignition will allow it to start without having a full transponder key in the ignition. Get an additional plain key cut if you want a spare.
