Troubleshooting Problems With BMW Keys
Before the i8 and 7 Series, BMW keys were rather clunky black rectangles that had to be put into the ignition slot to unlock the car and start it. But all that changed when the digital key was introduced.
But is it possible to hack? Also, can you use a keyfob that isn't genuine to activate Comfort Access in your BMW?
Keyless entry
If you've owned a BMW for long enough you're probably familiar with keyless entry and remote start. These features make your drive more convenient, and also make you safer. You can even lock and unlock your car from the at-home comforts of your home if you've got the right apps on your smartphone. 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 about, for example, whether their key fobs can be stolen. BMWs were designed with security in mind and are therefore virtually impossible to hack. The system is based on sending a distinct identifying signal from your key fob to the car, which is checked and then allowed to unlock. This means that other parties cannot copy your fob or use a signal amplifier to access your vehicle.
The BMW fob is typically put to sleep. If the fob isn't used for a specific period of time, it will go to sleep. This is to help conserve battery power and also prevent the car from opening when it's not supposed. However the key fob will function in the ignition when it's again pressed.
In addition to the keyless entry, the BMW key fob is also able to lock and unlock the vehicle, or enable the automatic transmission of cars that have manual shifters. The BMW key fob also controls comfort functions like seats, steering wheel, and mirror adjustments. It can also save personal settings such as the radio presets, seat positions and many more functions.
BMW key fobs can also be used to unlock a trunk or activate a push-button starter on some models. Press the button at the bottom of the fob until you hear it beep. Then, you can 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 vehicle's media system and climate control.
Electronic immobilizer
The engine immobilizer, a safety feature, helps to prevent car thefts by ensuring only the correct keys can be used to start the vehicle. It does this by verifying that the key's code is identical to the one stored on the computer. The engine will only start only if the codes match. This method has been used for more than 20 years and has contributed in reducing vehicle theft. It's also a great 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 a key fob, or key with a transponder. The chip transmits a passcode from the key fob or key to the immobilizer system of the car and is integrated into the PCM (or BCM), instrument cluster or smart junction boxes or other modules. The immobilizer unit then verifies 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 only transmitted 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 a common case of stolen cars.
It will sound an alarm when it is unable to recognize the code on the key or the key fob. It will also shut down the ignition coil, or injectors, depending on the type of engine in your car. The engine will begin to run for a few moments, then shut down. It's impossible to drive away.
Immobilizers are an excellent security device that has reduced vehicle thefts by blocking hot wiring. However, it's not foolproof and a number of criminals have devised methods to get around 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.
A device can be used to change the code of the key or transponder chip. You can do this by purchasing the "transponder-reader" on the internet. These tools do not always work however they can be useful in certain instances.

A drained or faulty battery will also prevent the remote starter from working. This is a crucial security feature in a lot of automobiles, so you must replace the battery as quickly as possible. If you own a BMW that has the push button to start, you'll need to go to the dealership to connect the additional fobs and to program the new key.
