Troubleshooting Problems With BMW Keys Before the i8 and 7 Series, BMW keys were rather clunky black rectangles that needed to be inserted into the ignition slot to unlock and start the car. But that all changed when the digital key was introduced. But can it be hacked? You can use a keyfob that's not genuine to activate Comfort Access on your BMW? Keyless entry If you've been driving a BMW for some time, you're no stranger to keyless entry and remote start. These features are convenient and ensure that you're driving safely. If you have the appropriate apps installed on your phone you can lock and unlock your vehicle from the comfort of home. These key fobs aren't without their quirks, just like any other new technology. Some BMW owners wonder, for example, if their key fobs can be stolen. BMWs are designed with security in mind, which means they're almost impossible to hack. The system operates by sending an identifying signal unique to your key fob, which is then verified to unlock the vehicle. This means that third parties can't clone your fob or use an amplifier to gain access to your vehicle. The BMW fob is usually put to sleep. If the fob isn't pressed for a specific period of time it will go into sleep. This helps conserve battery power, and also stops the car from opening uninvited. The key fob is able to be used to open the ignition by pressing it again. The BMW key fob, in addition to keyless entry, can lock and unlock a vehicle or activate automatic transmission on cars with manual shifting. The BMW key fob also controls comfort functions like steering wheel, seat, and mirror adjustments. It also stores personal settings, including presets for the radio and seat position and permit owners to unlock their BMW using the MyBMW app on their smartphones. BMW key fobs can be used to unlock a trunk, or to trigger the push-button starter on certain models. To activate this feature, press the button at the bottom of the fob until it beeps. Insert the key into the trunk opening and pull it down to unlock the trunk. The BMW key fob can also control the climate control of the vehicle as well as the media system. Electronic immobilizer The engine immobilizer is a crucial safety feature that helps to protect against theft of cars by ensuring that only the right key is used to start the car. This is accomplished by checking the code on the car key to the one stored in computer. The engine will only begin only if the codes match. This system has been around for more than 20 years, and it has drastically reduced vehicle theft rates. It's also a good method to prevent hotwiring which is the act 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 a transponder chip. The chip transmits a passcode from the key fob or key to the immobilizer unit of the car and is integrated into the PCM (or BCM), instrument cluster and smart junction boxes or other modules. The immobilizer unit then verifies the passcode 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 by the authorized key fob or key. These cryptographic algorithms were designed to be difficult to crack by hackers. This technology also guards against remote key duplication, which is common in the instance of stolen vehicles. If the immobilizer does not recognize the code on the key or key fob, it will sound an alarm. 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 few seconds and then stop which makes it impossible to drive the vehicle away. Immobilizers are a fantastic security device that has helped reduce vehicle thefts through the prevention of hot wiring. However, it is not foolproof, and many thieves have come up with ways to thwart the immobilizer. This includes using a computer to break the algorithm. This can be done by using a special program. A device can be used to modify the code of the key or the transponder chip. This can be done using a tool called a "transponder reader" which is available online for purchase. These devices aren't a reliable method of defeating the immobilizer, but they can help in some cases.
