What is a Transponder Key?
By definition, a transponder key is a device that transmits or accepts data from another device. Transponder keys use a miniature transponder which is embedded in the key head. When the key is inserted into the ignition, a radio frequency is transmitted to the key. This energizes the transponder which replies with an ID number. If the ID number is recognized by the onboard computer, the ignition and starting system is enabled.
This type of transponder key does not need a power source of their own. They operate in the frequency range area of 125 kHz. This means they are very limited in range and generally operate in the range of 1cm to 15 cm. Since this is a radio frequency it can penetrate materials that would make the transponder not directly visible, such as the plastic or rubber in the bow of a key.
Many later model vehicles feature keys that have keyless entry. These keys can be loaded with large amount of unique codes, which gives a vehicle another level of security and allows individuals to access their cars through keyless entry.
