But is bmw key programmer to hack? Also, can you use a non-genuine keyfob to enable Comfort Access in your BMW?
Keyless entry

If you have been driving in a BMW car for some time, you are likely to be familiar with remote starting and keyless entry. These features make driving more convenient, and also keep you safer. You can lock and unlock your vehicle from the comfort of your home provided you have the appropriate apps on your smartphone. But, like all new technology key fobs, these key fobs come with certain quirks that can be confusing.
Some BMW owners are concerned about, for example, whether their key fob can be stolen. BMWs are designed with security in mind, which means they're nearly impossible to hack. The system is based on sending a distinct identifying signal from your key fob to your car, which is verified and allowed to unlock. This means that a third party cannot duplicate or use a signal amplifier to access your car.
The BMW fob is often put to sleep. If the fob doesn't get pressed for a certain amount of time, it will go to sleep. This can help conserve battery power and prevents the car from opening uninvited. However the key fob will function in the ignition when it's pressed again.
The BMW key fob, in addition to keyless entry, can also lock and unlock a car or enable automatic transmission on cars with manual shifting. The BMW key fob will also be able to control certain aspects of the car's features for comfort like mirror, seat and steering wheel adjustments. It can also save personal settings like presets for radio, seat position and many other functions.
The BMW key fob can also be used to unlock the trunk or to turn on a push button starter in some models. To activate this feature, press the button on the bottom of the fob until it sounds. Then, you can insert the key into the trunk opener and pull it down to unlock the trunk. The BMW key fob also has the capability of controlling the vehicle's media system and climate control.
Electronic immobilizer
The engine immobilizer, which is a security feature, helps to prevent car thefts by making sure that only the correct key is used to start the vehicle. It does this by ensuring that the code on the key matches the one stored on the computer. If the codes are compatible, the engine will be allowed to begin. This method has been in use for more than 20 years, and has significantly reduced vehicle theft rates. It's also a great way 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 part of the key fob, or a key with a transponder. The chip transmits a code to the car's immobilizer system which is embedded in the PCM, BCM, instrument cluster, smart junction box, or other module. The immobilizer unit then verifies the passcode and allows the engine to start if the passcode is right.
Modern transponder chips and keys utilize a cryptographic algorithm in order to ensure that the code is only transmitted once and only to the authorized key fob or key. These cryptographic algorithms were developed to be hard to decode by hackers. This technology also shields against remote key duplication, which is common in the case of stolen cars.
If the immobilizer does not recognize the code on the key fob or the key it will sound an alarm. It could also disable the fuel pumps, ignition coils or injectors, depending on the type of engine in your vehicle. The engine will begin to run for a few moments before it will shut down. It is impossible to drive away.
An immobilizer is an excellent safety feature, and it has reduced the risk of theft of vehicles by preventing hot-wiring. However, it is not foolproof, and many criminals have devised methods to get around the immobilizer. These methods include the use of a computer to decode the algorithm. This can be accomplished using a program that is specifically designed for this purpose.
Another method is to use a device to change the code of the transponder chip, or key. You can purchase a "transponder-reader" on the internet. These tools don't work every time however they can be useful in some cases.
