A transponder is a device that sends out signals to another device, often to verify its identification. A transponder key is a vehicle key that communicates with the car to confirm that the identification number of the key matches the number of the car. If they match, the car will start, if they don’t, the car does not start and sometimes immobilizes. Transponder keys help prevent car theft because the only ones who can start the car is the individual who is holding the key.
A chip is installed in the key that sends out radio signals to a receiver in the car when it is used – either to unlock the car or to start it. The transponder key has a unique serial number, built in by a transponder programmer, which the computer chip in the receiver verifies that it matches the car’s own serial number. Once it has confirmed a match, the receiver gives the “Go” signal to the car and allows it to start or unlock.
Transponder keys are hard to duplicate because in order to do so, one would also need to duplicate the transponder with the special 30 digit serial number that is hidden in the key. However, there are still many ways for thieves to steal a car so having a transponder key does not give the owner permission to be negligent in guarding their cars. Also, a blank transponder key can unlock cars. These blank keys have not been programmed yet and can adjust itself to a car’s unique code.
For people who have cars that use transponder keys, owners are advised to have duplicates. Misplacing car keys are very common and it’s almost impossible to unlock a car without its transponder key. These keys can be duplicated but it takes a long time to do so since it is a very unique key. Usually, only the vehicle dealers themselves can duplicate these keys. Keep in mind that there are some dealers who prefer not to give information to locksmiths. It is a good idea to have another person keep one of your keys or have another set of keys hidden in a safe place you have access to.
