But that all changed when the digital key came out. But can it be hacked? You can use a keyfob that's not authentic to activate Comfort Access on your BMW? Keyless entry If you've been driving a BMW car for a while, you are likely to have heard of remote start and keyless entry.

These key fobs aren't without their quirks, just like any other new technology. Some BMW owners are unsure whether, for instance, their key fob can be hacked. BMWs are designed with security in mind, so they're nearly impossible to hack. The system is based on sending a distinct identification signal from your key fob to your car, which is then verified and allowed to unlock. This means that a third party cannot duplicate or use a signal amplifier to gain access to your car. The BMW fob is typically put to sleep. The fob will go into sleep if it is not pressed for a set amount of time. This is done to conserve battery power and prevent the car from opening when it's not supposed. However the key fob can work in the ignition if it's repeatedly pressed. The BMW key fob, in addition to keyless entry, can also lock and unlock a vehicle or activate automatic transmission on vehicles that have manual shifting.

Electronic immobilizer The engine immobilizer is a crucial security feature that can help protect against theft of cars by ensuring that only the correct key is used to start the vehicle. This is accomplished by using the key's code to the one stored on the computer. If the codes match the computer, the engine is allowed to begin. This method has been used for over 20 years and has helped in reducing vehicle theft. It's also a good way to prevent hotwiring, which is the process of bypassing the ignition switch by connecting wires between the ignition coil and the fuel pump relay. The immobilizer is a part of the key fob or key that contains the transponder chip. The chip transmits a passcode from the key fob or key to the immobilizer system of the vehicle that is integrated into the PCM (or BCM), instrument cluster or smart junction boxes or other modules. The immobilizer unit verifies the code and permits engine to start if it is verified that the passcode is correct. Modern transponder chips and keys utilize a cryptographic algorithm in order to ensure that the code is only transmitted once and only to the authorized key fob or key. These cryptographic algorithms were designed to be difficult to crack by hackers. This technology guards against remote key replication which is a frequent occurrence when cars are taken. If the immobilizer cannot recognize the code on the key or key fob, it will sound an alarm. It could also disable the ignition coils, fuel pumps or injectors, depending on the engine type in your vehicle. The engine will run for a few moments, then shut down. It is impossible to drive away. Immobilizers are a fantastic security feature, and it has been a great help in reducing vehicle theft by preventing hot-wiring.

This can be done using a program that is specifically designed for this purpose. A device can be used to change the code of the key or transponder chip. You can do this by purchasing an "transponder-reader" on the internet. These aren't a reliable method of defeating the immobilizer, but they may assist in certain situations.
