Modern automobiles employ rolling/changing security codes in an advanced electronic engine immobilizer system. This system, which has two levels of security, is found in BMW vehicles. a constant personal code and a second code that changes. The mechanism updates the second code and stores it in the key each time the key starts the engine. Every time the driver turns the ignition on, the immobilizer first reads the personal code. It then asks for the second rolling code.

Only when both of these codes are correct does the immobilizer unlock the engine by sending another coded signal to the engine management system. The engine will not start without it. Even if someone tries to short the ignition circuit in the absence of the second security code, the engine will not start. As a result, it stops car theft.

While engine immobilizers can deter auto theft, other thieves are even more determined. Thieves always manage to find a way to get past the security measures that are put in place. Many thieves keep up with the times when it comes to engine immobilizers and devise techniques to decipher the transponder codes and start vehicles, just like they did in the past.
