What are Automotive Transponder Keys?
The biggest change to the automotive industry in recent times has been the introduction of the built in immobilise system on all cars manufactured since 1995 (late '94 in some cases). This involves placing a microchip in the head of the key, which is a miniature transmitter and receiver. There is an engine management system in the engine compartment that can recognise the signals transmitted from the key. If the correct signals are not detected the engine will not start.
How does the Microchip work?
An electronic chip with a permanent memory which contains an ELECTRONIC CODE. The transponder has an antenna with which it can interface with an external electronic control device.
Through the antenna the device emits a fixed frequency signal; the transponder receives the signal and then transmits its electronic code, by means of special frequency modulations, to the control device, which is able to process the code.
The transponder has no external input of power supply (passive system); it receives the energy necessary to work from the signal emitted by the external control device (inductive coupling between the control device antenna and that of the transponder).
We Can Program all fixed code transponders and some crypto transponders using Diagnostics Programing Equipment connected to your cars immobiliser computer

Immobiliser Technology
Immobiliser Technology is integrated with your automobiles Electronic Management System computer, via an aerial located in the proximity of the ignition switch. It detects a coded microchip housed in the ignition key, without the signature of the microchip being detected the automobile will not start. The microchip within the ignition key also uses passive technology and therefore there is no need to worry about batteries going flat or replacements like most automotive applications.
