There are many types and variations of anti-theft transponder/immobilizer systems on the market. The word Transponder Key Long Beach comes from the words transmitter and responder. Without going into detail on each type, let us generalize about how they work and what to look for. There can be two to four components. The majority of cars sold today have a key with a transponder in it, (radio frequency identification chip, RFID); an induction coil (antenna of sorts) around the ignition that communicates with the key; and a computer in the vehicle that receives communication from the antenna telling it the code from the key. These Magnetic Coupled Transponder systems are passive, thus do not have their own power, and the key must be in close proximity to the antenna to communicate at the 125 kHz frequency range.
If the computer recognizes the code from the key, it will send a signal allowing the car to start. Without the correct Transponder Key Long Beach (chip in the key), the car will be immobilized. Some keys manufactured today no longer have the mechanical key cut, they instead rely only on the transponder to activate the system and allow the vehicle to start. Most systems will immobilize the fuel, starter, or both, if the incorrect key or transponder is used. Older keys use the same code continually, which made it possible for suspects to use code grabbers to electronically capture the code and bypass or clone it. Many of today’s vehicles utilize what is referred to as a rolling code, which means that the code changes with each use of the key, making conventional code grabbing devices useless. Without the correct code, the car will not start. Rolling codes are also used with keyless entry devices on most models today.
