Car Key Replacement Chislehurst Immobiliser Information
An immobiliser is an electronic security device fitted to a motor vehicle that prevents the engine from starting unless the correct transponder key or remote is present. This prevents the vehicle from being hot wired after entry has been achieved and helps to reduce motor vehicle theft.

Early models used a static code in the ignition key or Remote which was recognised by a receiver around the ignition lock this code is checked against the vehicle’s engine control unit ECU for a match. If the code was unrecognised the ECU will not allow fuel to flow and or ignition to take place.
Later models use rolling codes or advanced cryptography to defeat copying of the code from the key or ECU.
The small electronic circuit inside the key is activated by an electromagnetic field which induces current to flow inside the key body, which in turn broadcasts a unique binary code which is read by the cars ECU. When the ECU determines that the coded key is both current and valid, the ECU activates the fuel-injection sequence.
In some vehicles attempts to use an unauthorised or “non-sequenced” key cause the vehicle to activate a timed no-start condition and in some highly advanced systems, even use satellite or mobile phone communication to alert a security firm that an unauthorised attempt was made to code a key.
