Transponder Car Keys And How They Work

30 November 2017 Posted by admin Locksmith News

Transponder immobiliser systems were introduced to vehicles in Germany in about 1995. The rise of car theft and the market for cheap second hand parts led the decision to increase the difficulty in sourcing “hot” parts and cheap cars. The Japanese came on board early with their vehicles but did not go down the route of rolling code systems like Germany. Mitsubishi and Toyota were among the first to incorporate Transponder based immobilisers into models such as Lancer, Magna,Camry and Corolla.

There are two main types of chips used in car keys, as pictured here, there is a glass chip and there is a carbon chip. These chips are programmed with data or binary code that the cars ECU or BCM needs to receive before the car is allowed to start. The mechanism that is used to transfer this data from the chip to the immobiliser is called a reader, generally a copper coil that sits around the ignition lock. If the key is lost or the chip is damaged the process of resetting the system and making new transponder chips can be a costly and time consuming exercise.

As well as transponder chips many manufacturers are now incorporating pin codes as part of the cars security. This means that to communicate with the cars system in the event all working keys are lost or even to program spare keys, a four or 5 digit code may be required. A bit like getting money from the ATM, if you don’t have the pin code you won’t get money from your bank. There are many tools on the market now that allow a trained Automotive Locksmith to make new or replacement keys to 90% of vehicles on our roads today.
