Troubleshooting Problems With BMW Keys Prior to the i8 and 7 Series BMW keys were pretty clunky black plastic rectangles that needed to be put into the ignition slot to unlock the car and start it The digital keys changed everything However can it be hacked Do you have to use a keyfob that is not genuine to enable Comfort Access on your BMW Keyless entry If you have been driving in a BMW car for a while you are likely to be familiar with remote start and keyless entry These features are easy to use and can help to make driving safer If you have the appropriate apps installed on your smartphone you can lock and unlock your vehicle at home These key fobs arent without flaws just like all new technologies For instance many BMW owners wonder if their key fob can be hacked BMWs are designed with security in mind so theyre almost impossible to hack The system is based on transmitting a unique identifier to your key fob which is then verified to unlock the car This means that third parties cannot copy your fob or use an amplifier to access your vehicle Another issue that people ask is whether or not the BMW fob sleeps If the fob isnt used for a set period of time it will go to sleep This helps save battery power and prevents the car from opening without permission However the key fob will function in the ignition when it is pressed again In addition to the keyless entry the BMW key fob is also able to lock and unlock the car or turn on the automatic transmission in cars with manual shifters The BMW key fob can also control some of the cars comfort features including seat mirror and steering wheel adjustments It can also save personal settings like radio presets and seat position and permit owners to unlock their BMW through the MyBMW app on their mobile phones The BMW key fob can be used to unlock the trunk or activate the push button starter on certain models To do this simply press the button at the bottom of the fob until it tinks Then insert the key into the trunk opener and pull it back to unlock the trunk The BMW key fob also controls the climate control of the vehicle as well as the media system Electronic immobilizer The engine immobilizer is an essential safety feature that helps to prevent car theft by ensuring that only the correct key is used to start the vehicle It does this by ensuring that the keys code matches the one stored on the computer The engine will only begin when the codes are identical This system has been in operation for more than 20 years and has been able to decrease the theft of vehicles Its also a great method to prevent hotwiring which is the practice of bypassing the ignition switch by connecting wires between the ignition coil and the fuel pump relay The immobilizer is a part of a key fob or key that has a transponder The chip transmits a passcode from the key fob or key to the immobilizer unit of the car that is integrated into the PCM or BCM instrument cluster smart junction boxes or other modules The immobilizer device then validates the passcode and allows the engine to start if it is valid Modern keys and transponder chip utilize cryptographic algorithms to ensure that codes are sent only once and only by authorized key fobs or keys These cryptographic algorithms were developed to be hard to decode by hackers This technology is protected against remote key replication which is a frequent occurrence when cars are stolen If the immobilizer cannot recognize the code on the key or fob it will sound an alarm It will also disable the ignition coil or injectors dependent on the type of engine used in your vehicle The engine will start for a short period of time before it will shut down The Key Lab is 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 get around the immobilizer These methods include using a computer to break the algorithm 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 This can be done using a tool calledtransponder reader or transponder reader that is available on the internet for purchase These tools are not a reliable method of defeating the immobilizer but they may assist in certain situations Replace the battery If your BMW key fob isnt working as well as it used to and youre in need of an upgrade to the battery Its simple to replace the battery in your BMW and
