The transponder or chipped keys come with an RFID (Radio Frequency Identification) chip inside the head of the key. The word transponder is made up of two words- transmitter and responder. This unique technology was introduced in 1995. Ever since it penetrated the market, the demand has increased tremendously because almost all the new cars have a transponder key.
The success of the transponder key technology made it to be adopted by home security system manufacturers. So what exactly are transponders and how do they operate?
Every operation of the transponder is based on the RFID (in the head of the key) which transmits a low-level signal from the key to the receiver in the car. Each transponder key is programmed with a unique serial number matching up to the digital serial number in the car. The car only unlocks when it identifies the correct serial number.
Literally, it is impossible to hot-wire or open cars with transponder keys. This is because the transponder and the receiver use RFID technology for all communication making it difficult for the engine to start without the correct key.
All transponder keys have one thing in common, a chip inside them. Manufacturers just make different kinds and sizes and so there are many options available now.
