Numerous vulnerabilities have been found in the immobilisers designed to protect modern cars from theft. Many vehicle immobilisers use the
Megamos chip, which has been proven to be crackable. The Megamos transponder is one of many different transponders found in today's immobiliser systems and also

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

Some immobiliser systems tend to remember the last key code for so long that they may even accept a non-transponder key even after the original key has been removed from the ignition for a few minutes.
