15 Reasons Not To Ignore BMW Keys
Troubleshooting Problems With BMW Keys
BMW keys used to be large, black plastic rectangles. They were put into the ignition to turn on and unlock the car. The digital key changed everything.

For instance, many BMW owners wonder if their key fobs are hackable. BMWs are designed with security in mind, so they're almost impossible to hack.

The BMW fob is usually put to sleep. If the fob doesn't get pressed for a specific period of time it will go to sleep. This is a way to conserve battery power, and stops the car from opening uninvited. However, the key fob can work in the ignition if it's again pressed.
The BMW key fob as well as keyless entry, can lock and unlock a car or turn on automatic transmissions for cars that have manual shifting.

Electronic immobilizer
The engine immobilizer is a crucial safety feature that helps to prevent car theft by ensuring that only the right key is used to start the vehicle. This is accomplished by using the code on the car key to the one stored in computer. The engine will only be able to start if the codes match. This system has been around for more than 20 years, and it has drastically reduced vehicle theft rates. It is also a reliable method 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 part a key fob, or key with a 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 or smart junction boxes or other modules. The immobilizer device validates the code and allows the engine to start if the passcode is valid.
Modern transponder chips and keys use a cryptographic algorithm to ensure that the code is only transmitted once and only to the authorized key fob or key. These cryptographic algorithms were developed to be difficult to decode by hackers. This technology is protected against remote key replication, which is common when cars are taken.

Immobilizers are a fantastic security device that has helped reduce vehicle thefts by blocking hot wiring. However, it is not foolproof and a number of thieves have devised ways to defeat the immobilizer. These methods include using a computer to break the algorithm. This can be accomplished using a program that is specifically designed for this purpose.
Another method involves using an instrument to alter the code on the transponder chip or key. You can accomplish this by purchasing a "transponder-reader" online. These tools don't perform every time however, they can be useful in some cases.
