Auto Locksmiths Perth can program transponder keys for many different makes and models of vehicles. Many people ask us what a transponder key is, as most customers don’t know that their car key most likely has one built in to the head of the key. A transponder is a microchip that disarms a vehicles immobiliser when the car key is inserted into the ignition. When the cars key is inserted into the ignition the car’s engine control unit sends a message or equation to be solved by the transponder in the key.
Even keys without integrated remotes need to be programmed to start the car, and some vehicles in Australia such as the Toyota Camry have been using transponders since 1996. If you would like to know more about transponder keys and if your car has one, find your make and model on our website or send us a message and we will get in contact with you.
They are used in aircraft to emit signals in response from signals from the ground. On a highway, a transponder is used on toll roads to collect data from the passing cars. The difference between these and the one found in your car is that the one in your car key is referred to to as a “passive transponder” meaning it doesn’t require a power supply to run. Because of this, they only emit a signal to a very small area usually 1cm to 10cm
Transponders have been mandatory in Australia since 2001, and immobilisers have been required by law since 1996. Reports have shown that these devices have led to up to a 40% drop in car thefts.
