Troubleshooting Problems With BMW Keys BMW keys used to be large black rectangles of plastic. They were put into the ignition to begin and unlock the car. The digital keys changed everything. But can it be hacked? Also, can you use a keyfob that isn't genuine to enable Comfort Access in your BMW? Keyless entry If you've owned a BMW for long enough you're familiar with keyless entry and remote start. These features are easy to use and help to make driving safer. If you've got the right apps installed on your smartphone you can lock and unlock your vehicle from the comfort of home. However, just like any other new technology key fobs, these key fobs come with some quirks that can get confusing. Some BMW owners are unsure whether, for instance, their key fobs can be stolen. BMWs were designed with security and therefore are nearly impossible to hack. The system operates by sending a unique identification signal from your fob to the car, which is then checked and then allowed to unlock. This means that a third-party cannot duplicate or use a signal amplifier to access your car. Another question that people have is whether or not the BMW fob will go to sleep. The fob will go into sleep if it's not operated for a predetermined amount of time. This is a way to conserve battery power, and stops the car from opening without permission. However, the key fob will still work when it is repeatedly pressed. The BMW key fob, in addition to keyless entry, can also lock and unlock a vehicle or turn on automatic transmissions for cars that have manual shifting. The BMW key fob will also be able to control certain aspects of the car's comfort features including mirror, seat, and steering wheel adjustments. It can also store personal settings like presets for radio, seat position and other functions. The BMW key fob can also be used to unlock the trunk, or activate the push button starter on some models. Press the button on the bottom of the fob until you hear it ring. Then, insert the key into the trunk opener and pull it down to unlock the trunk. The BMW key fob is also capable of controlling the car's media system and climate control. Electronic immobilizer The engine immobilizer is an essential security feature that helps protect against theft of cars by ensuring that only the correct key is used to start the vehicle. It does this by verifying that the key's code matches the one stored on the computer. The engine will only begin if the codes match. This system has been in operation for more than 20 years, and has significantly reduced vehicle theft rates. It is also a great way to prevent 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 of the key fob or key that has a 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 and smart junction boxes or other modules. The immobilizer unit checks the passcode and allows the engine to start if it is valid. Modern transponder chips and keys utilize cryptographic algorithms to ensure that codes are sent only once, and only by authorized keys or key fobs. These cryptographic algorithms were created to be hard to decode by hackers. This technology also guards against remote key duplication, which is a common situation of stolen cars. It will sound an alert in the event that it cannot recognize the code from the key or fob. It will also disable the ignition coil, or injectors depending on the type of engine used in your vehicle. The engine will turn on for a few seconds, and then stop, making it impossible to drive the car away. An immobilizer is a great safety feature, and it has reduced the risk of theft of vehicles by preventing hot-wiring. However, it is not foolproof, and a lot of thieves have come up with ways to get around the immobilizer. Some of these strategies include using a laptop to decode the cryptographic algorithm, which is possible using the use of a specific software program. A device can be used to modify the code of the key or the transponder chip. This can be done by using a tool called a “transponder reader,” which is available online for purchase. These tools do not work every time however they can be useful in certain instances.
