20 Fun Details About BMW Keys
Troubleshooting Problems With BMW Keys
Prior to the i8 and 7 Series, BMW keys were quite clunky black plastic rectangles that needed to be placed into the ignition slot to unlock and start the car. The digital key changed everything.
But can it be hacked? Do you have to use a keyfob which is not genuine to activate Comfort Access on your BMW?
Keyless entry
If you've owned a BMW for any length of time you're probably familiar with keyless entry and remote start. These features make driving more convenient, and they also make you safer. You can lock and unlock your vehicle from the convenience of your home, when you have the right apps on your phone. However, just like any other new technology keys have certain quirks that can be confusing.
For example, some BMW owners wonder if their key fob can be hacked. BMWs are designed with security in mind, so they're nearly impossible to hack. The system is based on sending a distinct identification signal from your fob to your car, which is confirmed and permitted to unlock. This means that unauthorized parties can't clone your fob or use a signal amplifier to gain access to your vehicle.
The BMW fob is typically put to sleep. If the fob doesn't get pressed for a certain period of time it will go into sleep. This helps save battery power and stops the car from opening without permission. The key fob can be used to open the ignition by pressing it once more.
In addition to the keyless entry, the BMW key fob can also lock and unlock the car, or enable the automatic transmission on cars with manual shifters. The BMW key fob also controls comfort functions like steering wheel, seat and mirror adjustments. It can also save personal settings like presets for radio, seat position and many other functions.
BMW key fobs can also be used to unlock a trunk or activate a push-button starter on some models. Press the button on the bottom of the fob until you hear it sound. Then, insert replacement key for bmw into the trunk opener and pull it down to unlock the trunk. The BMW key fob also controls the vehicle's climate control as well as media system.
Electronic immobilizer
The engine immobilizer, a security feature, prevents car thefts by ensuring only the correct keys can be used to start the car. It does this by verifying that the key's code matches the one stored on the computer. If the codes are compatible the codes, the engine will be allowed to start. This system has been around for more than 20 years, and it has greatly reduced the number of stolen vehicles. It's also a good 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 key that contains the transponder chip. The chip transmits a passcode to the immobilizer system of the car which is embedded in the PCM, BCM, instrument cluster, smart junction box, or another module. The immobilizer unit verifies the code and permits engine to start if it is verified that the passcode is valid.
Modern transponder chips and keys employ a cryptographic algorithm to ensure that the code is only transmitted once and only by the authorized key fob or key. These cryptographic algorithms were designed to be difficult to decode by hackers. This technology protects against remote key replication, which is a frequent occurrence when cars are stolen.
It will sound an alert when it is unable to recognize the code on the key or key fob. It will also shut down the ignition coil, or injectors dependent on the type of engine that is in your vehicle. The engine will turn on for a few seconds, and then shut down and it will be impossible to drive the vehicle away.
An immobilizer is a great safety feature, and it has helped to reduce theft of vehicles by preventing hot-wiring. However, it is not foolproof and a number of thieves have devised ways to get around the immobilizer. These methods involve using a computer to break the algorithm. This can be accomplished by using a special program.
A device can be used to alter the code of the key or the transponder chip. You can accomplish this by purchasing a "transponder-reader" on the internet. These devices aren't an effective way of getting rid of the immobilizer, but they may assist in certain situations.
