Keyless entry
If you've been driving a BMW for some time, you're no stranger to keyless entry and remote start. These features make your drive more enjoyable, and also make you safer. If you have the appropriate apps installed on your smartphone you can lock and unlock your car from your home. But just like every new technology keys have certain quirks that can be confusing.
Some BMW owners wonder, for example, if their key fobs can be compromised. BMWs were designed with security in mind and are therefore nearly impossible to hack. The system is based on sending an identifying signal unique to your key fob which is then verified to unlock the vehicle. This means that other parties cannot copy your fob or use a signal amplifier to access your vehicle.
The BMW fob is often put to sleep. The fob will go into sleep if it's not operated for a predetermined amount of time. This is to conserve battery power and also prevent the car from opening when it shouldn't. The key fob can be used in the ignition by pressing it once more.
In addition to keyless entry, the BMW key fob can also lock and unlock the car, or turn on the automatic transmission in cars with manual shifters. The BMW key fob will also control some of the car's features for comfort like seat, mirror, and adjustments to the steering wheel.

Electronic immobilizer
The engine immobilizer is a crucial security feature that helps protect against theft of cars by ensuring that only the right key is used to start the car. It does this by verifying that the code on the key matches that stored in the computer. The engine will only be able to start if the codes match. This system has been in operation for more than 20 years, and it has drastically reduced the number of stolen vehicles. It is also an effective way to stop hotwiring. Hotwiring is the act of bypassing ignition switches by connecting wires from the ignition coil to the fuel pump relay.
The immobilizer is a component of the key fob or key that has the transponder chip. The chip transmits a passcode from the key fob or key to the immobilizer unit of the vehicle that is integrated into the PCM (or BCM), instrument cluster or smart junction boxes or other modules. The immobilizer device then validates the passcode and allows the engine to start if it is right.
Modern transponder chips and keys employ a cryptographic algorithm to ensure that the code is only transmitted once and only to the authorized key fob or key. These cryptographic algorithms are designed to be difficult for hackers to crack. This technology guards against remote key replication which is a frequent occurrence when cars are stolen.
If the immobilizer is unable to recognize the code on the key fob or the key, it will sound an alarm. It can also disable the ignition coils, fuel pumps or injectors based on the type of engine that is installed in your vehicle. The engine will be turned on for a few seconds and then die and it will be impossible to drive the vehicle away.
Immobilizers are an excellent security device that has reduced vehicle thefts by blocking hot wiring. However, it's not foolproof, and a lot of thieves have come up with ways to thwart the immobilizer. These methods include the use of a computer to decode the algorithm. This can be done by using a special program.
Another option is to use a device to change the code on the transponder chip or key. This can be done by using a tool called"transponder reader" or "transponder reader," that is available online for purchase. These devices aren't an effective way of getting rid of the immobilizer, but they may assist in certain situations.
