But, like all new technology key fobs, these key fobs come with certain quirks that can be confusing.
Some BMW owners are unsure, for example, if their key fob can be compromised. BMWs were designed with security in mind and are therefore nearly impossible to hack. The system works by transmitting a unique identifier to your key fob, which is then verified to unlock the car. This means that a third party cannot duplicate or use a signal amplifier to access your vehicle.
The BMW fob is often put to sleep. The fob will go to sleep if it is not operated for a predetermined amount of time. This is done to conserve battery power and stop the car from opening when it shouldn't. The key fob can still be used in the ignition by pressing it again.
In addition to keyless entry In addition to keyless entry, the BMW key fob can also lock and unlock the car or activate the automatic transmission on cars with manual shifters.

Electronic immobilizer
The engine immobilizer, a safety feature, helps to prevent car thefts by ensuring only the correct key can be used to start the vehicle. It does this by checking that the key's code matches the one stored on the computer. If the codes are compatible the computer, the engine is allowed to start. This system has been around for more than 20 years, and has significantly reduced the number of stolen vehicles. This system is also a great way to stop hotwiring. Hotwiring is the practice of bypassing ignition switches by connecting wires from the ignition coil to the fuel pump relay.
The immobilizer is part of a key fob or key with transponder. The chip transmits a passcode from the key fob or key to the immobilizer system in the car that is integrated into the PCM (or BCM), instrument cluster, smart junction boxes, or other modules. The immobilizer unit checks the passcode and allows the engine to start if it is correct.
Modern transponder chips and keys utilize a cryptographic algorithm in order to ensure that the code is only transmitted once and only by the authorized key fob or key. These cryptographic algorithms were designed to be difficult to crack by hackers. This technology also guards against key duplicates that are remote, which is a common case of stolen cars.
It will sound an alert if it does not recognize the code from the key or key fob. It can also disable the fuel pumps, ignition coils or injectors based on the type of engine in your vehicle. The engine will start for a short time and then stop. It is impossible to leave the vehicle.
Immobilizers are a great safety device that has helped reduce vehicle thefts by preventing hot wiring. However, it is not foolproof, and a lot of criminals have devised methods to defeat the immobilizer. These methods involve using a computer to break the algorithm. This can be done with a specific program.
Another option is to use an instrument to alter the code of the transponder chip or key. You can do this by purchasing the "transponder-reader" online. These tools do not work every time however they can be useful in certain instances.
