Troubleshooting Problems With BMW Keys
Prior to the i8 and 7 Series, BMW keys were rather clunky black rectangles that needed to be inserted into the ignition slot to unlock the car and start it. The digital key revolutionized everything.
But is it possible to hack? And can you use a non-authentic keyfob to activate Comfort Access in your BMW?
Keyless entry
If you've driven a BMW for some time you're familiar with remote start and keyless entry. These features make your drive more convenient, and also make you safer. You can also lock and unlock your car from the comfort of your home when you have the right apps installed on your smartphone. These key fobs aren't without flaws, just like all new technologies.
Some BMW owners are unsure, for example, if their key fobs can be stolen. BMWs are designed to be secure and are therefore virtually impossible to hack. The system is based on sending an identifying signal unique to your key fob, which is then verified to unlock the vehicle. This means that unauthorized parties can't clone your fob or use an amplifier to access your vehicle.
Another issue that people ask is whether or whether the BMW fob sleeps. The fob will go into sleep if it is not operated for a predetermined amount of time. This is done to conserve battery power and stop the car from opening when it shouldn't. The key fob can be used to open the ignition by pressing it again.
The BMW key fob is not only a keyless entry, can also lock and unlock a vehicle or turn on automatic transmissions for cars with manual shifting. The BMW key fob can also be used to control features of comfort, such as the seats, steering wheel, and mirror adjustments. It can also store personal settings, including radio presets and seat position, and allow owners to unlock their BMW using the MyBMW app on their smartphone.
The BMW key fob can also be used to unlock the trunk, or to activate a push button starter in some models. Press the button at the bottom of the fob until you hear it sound. Insert the key into the trunk opening and pull it down 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 is an essential safety feature that helps to prevent car theft by ensuring that only the right key is used to start the vehicle. It does this by verifying that the key's code is identical to that stored in the computer. The engine will only begin if the codes match. This system has been around for more than 20 years and has significantly reduced the number of stolen vehicles. It is also a good way 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 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 system of the car that is integrated into the PCM (or BCM), instrument cluster or smart junction boxes or other modules. The immobilizer device then validates the passcode and allows the engine to start if the passcode is correct.

Modern transponder chips and keys utilize cryptographic algorithms to ensure that codes are sent only once, and only through authorized keys or key fobs. These cryptographic algorithms were developed to be difficult to crack by hackers. This technology also guards against key duplicates that are remote, which is a common instance of stolen vehicles.
It will sound an alert when it is unable to recognize the code on the key or the key fob. It may also disable ignition coils, fuel pumps or injectors based on the type of engine in your vehicle. The engine will begin to run for a short period of time, then shut down. It's impossible to leave the vehicle.
Immobilizers are a great safety device that has helped reduce vehicle thefts by blocking hot wiring. It is not foolproof and many thieves have found ways to defeat it. Some of these methods include using a laptop to identify the cryptographic algorithm, which can be done with the use of a specific software program.
A device can be used to change the code of the key or transponder chip. This can be accomplished by using a device called a "transponder reader," that is available online for purchase. These devices aren't a reliable method of defeating the immobilizer, but they can help in some cases.
