Troubleshooting Problems With BMW Keys
Before the i8 and 7 Series, BMW keys were quite clunky black plastic rectangles that needed to be inserted into the ignition slot to unlock the car and start it. The digital key changed everything.
However, can it be hacked? Can you use a non-authentic keyfob to activate Comfort Access in your BMW?
Keyless entry
If you have been driving in a BMW car for long, you're probably familiar with keyless entry and remote starting. These features make driving more convenient, and also make you safer. You can even lock and unlock your car from the convenience of your home, if you've got the right apps on your phone. These key fobs are not without their quirks, just as with any new technology.
For example, some BMW owners wonder if their key fob can be hacked. BMWs were designed with security in mind and therefore are nearly impossible to hack. The system operates by sending an identifying signal unique to your key fob, which is then verified to unlock the car. This means that a third party can't duplicate or utilize a signal amplifier to access your vehicle.
Another question people are asked is whether or not the BMW fob goes to sleep. The fob will go to sleep if it is not pressed for a set amount of time. This helps conserve battery power, and also stops the car from opening without permission. The key fob can be used in the ignition by pressing it once more.
The BMW key fob, in addition to keyless entry, is able to lock and unlock a car or enable automatic transmission on cars that have manual shifting. The BMW key fob can also control some of the car's features for comfort, such as seat, mirror and steering wheel adjustments. It also stores personal settings, like radio presets and seat position and let owners unlock their BMW by using the MyBMW app on their smartphones.
BMW key fobs can also be used to unlock a trunk or activate the push-button start on certain models. To do this, press the button on the bottom of the fob until it sounds. Insert the key into the trunk opening, then pull it downward 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, a safety feature, prevents car thefts by ensuring only the correct keys can be used to start the car. This is done by comparing the key's code to the one stored in computer. If the codes match the computer, the engine is allowed to start. This system has been in operation for more than 20 years and it has drastically reduced the rate of vehicle theft. It is also a good method to avoid 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 a component of the key fob or key that contains the transponder chip. The chip sends a passcode to the immobilizer unit of the car which is embedded in the PCM, BCM, instrument cluster, smart junction box, or other module. The immobilizer unit verifies the code and allows the engine start if the passcode is correct.
Modern transponder chips and keys employ a cryptographic algorithm to ensure that codes are sent only once, and only through authorized keys or key fobs. These algorithms are designed to be difficult for hackers to break. This technology is protected against remote key replication, which is a frequent occurrence when cars are taken.
It will sound an alarm in the event that it cannot recognize the code on the key or key fob. It will also disable the fuel pump, ignition coil, or injectors, depending on the type of engine that is in your vehicle. The engine will be turned on for a few seconds and then die which makes it impossible to drive the car away.
An immobilizer is an excellent safety feature, and it has reduced the risk of theft of vehicles by preventing hot-wiring. However, it's not foolproof, and many criminals have devised methods 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 option is to use an instrument to alter the code of the transponder chip or key. You can do this by purchasing the "transponder-reader" online. These tools do not work every time, but can be helpful in certain instances.

For instance, if you are using the BMW Smart Key, it has a rechargeable battery that charges when inserted into the ignition. The battery isn't replaceable without cutting through the case.

Many BMW models from 2011 to 2017 use the sleek slant-shaped key battery, which is also known as a watch battery. The battery can be replaced by pressing an appropriate button close to the point where the key slides out of the case, and removing it. A small groove in the opening will show up and you can utilize a valet keys or screwdriver to rotate the groove clockwise in order to remove the cover.

You will usually be able to tell if the BMW key fob's battery is failing when you observe that the signal range of the device has diminished. Normally, you should be able to unlock your vehicle from approximately 30 to 60 feet. If you can't get closer than 20 feet then it's time to replace the battery.
A drained battery will also cause the remote starter to stop working. It's a safety feature that is found in many vehicles and it's crucial to replace the battery as quickly as you can. If you own a BMW with push button start, you'll need to visit the dealer to program the new key fob, and then sync additional fobs to the vehicle.
