Troubleshooting Problems With BMW Keys BMW keys used to be large black rectangles of plastic. They were inserted into the ignition to turn on and unlock the car. The digital key changed everything. But can it be hacked? And can you use a keyfob that isn't genuine to enable Comfort Access in your BMW? Keyless entry If you have been driving in a BMW car for some time, you are probably familiar with remote starting and keyless entry. These features are convenient and also ensure that you're driving safely. If you've got the right apps on your smartphone, you can lock and unlock your car from the comfort of home. However, just like any other new technology key fobs, these key fobs come with certain quirks that can be confusing. For example, some BMW owners wonder if their key fob can be hacked. BMWs are designed with security in mind, which means they're almost impossible to hack. The system operates by sending a unique identification signal to your key fob which is then verified to unlock the car. This means that a third-party can't duplicate or use a signal amplifier to gain access to your vehicle. Another question that people have is whether or not the BMW fob sleeps. The fob will go into sleep if it is not operated for a predetermined amount of time. This is a way to save battery power and prevents the car from opening without permission. However the key fob will still work when it's pressed again. The BMW key fob is not only a keyless entry, is able to lock and unlock a car or activate automatic transmission on cars with manual shifting. The BMW key fob will also be able to control certain aspects of the vehicle's comfort functions including seat, mirror and adjustments to the steering wheel. It also stores personal settings, such as the presets for radios and seat positions and let owners unlock their BMW using the MyBMW app on their smartphone. BMW key fobs can also be used to unlock a trunk or to activate a push-button starter on some models. Press the button at the bottom of the fob until you hear it beep. Insert the key into the trunk opening, then pull it downward to unlock the trunk. The BMW key fob can also be used to control the vehicle's climate control as well as media system. Electronic immobilizer The engine immobilizer, which is a security feature, prevents car thefts by ensuring that only the correct keys can be used to start the vehicle. This is accomplished by comparing the code on the car's key with the one stored in a computer. The engine will only start only if the codes match. This system has been in use for more than 20 years and has been able to decrease the theft of vehicles. It is also a good method to avoid 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 part of the key fob or key that contains a transponder chip. The chip transmits a code to the car's immobilizer system which is embedded in the PCM, BCM, instrument cluster or smart junction box or any other module. The immobilizer unit checks the passcode and allows the engine to start if the passcode is right. Modern transponder chips and keys use a cryptographic algorithm to ensure that the code is transmitted only once and only to the authorized key fob or key. These algorithms are designed to be difficult for hackers to crack. This technology also shields against remote key duplication which is common in the situation of stolen cars. If the immobilizer cannot recognize the code on the key fob or the key it will sound an alarm. bmw 3 series key fob TheKeyLab will also disable the ignition coil, or injectors depending on the type of engine that is in your car. The engine will begin to run for a short period of time and then stop. It's impossible to drive away. Immobilizers are a fantastic security feature, and it has been a great help in reducing theft of vehicles by preventing hot-wiring. However, it is not foolproof, and a lot of thieves have come up with ways to thwart the immobilizer. Some of these methods include using a laptop to decode the cryptographic algorithm, which is possible using an application that is specifically designed for this purpose. Another method involves using an instrument to alter the code of the transponder chip, or key. You can accomplish this by purchasing an “transponder-reader” on the internet. These aren't an effective way of getting rid of the immobilizer, but they can assist in certain situations.
