Troubleshooting Problems With BMW Keys
BMW keys were large, black plastic rectangles. They were inserted into the ignition to start and unlock the car. The digital key revolutionized everything.
However, can it be hacked? Can you use a non-authentic keyfob to activate Comfort Access in your BMW?
Keyless entry
If you've had the privilege of driving in a BMW car for long, you're likely to be familiar with keyless entry and remote starting. These features make driving more enjoyable, and also make you safer. You can even lock and unlock your vehicle from the at-home comforts of your home provided you have the appropriate apps installed on your smartphone. But, like all new technology keys have certain flaws that can become confusing.
For instance, some BMW owners are concerned about whether their key fobs are hackable. BMWs are designed with security in mind, so they're virtually impossible to hack. The system operates by sending a unique identification signal from your fob to your car, which is verified and allowed to unlock. This means that other parties aren't able to copy your fob or use an amplifier to access your vehicle.
The BMW fob is often put to sleep. If the fob isn't pressed for a certain amount of time, it will go to sleep. This is a way to conserve battery power and stops the car from opening uninvited. However the key fob will still function in the ignition when it's again pressed.
The BMW key fob as well as keyless entry, is able to lock and unlock a vehicle or turn on automatic transmissions for cars that have manual shifting. The BMW key fob will also be able to control certain aspects of the vehicle's comfort functions including seat, mirror, and adjustments to the steering wheel. It also stores personal settings, including presets for the radio and seat position and let owners unlock their BMW through the MyBMW app on their smartphone.
BMW key fobs can be used to unlock a trunk or to activate the push-button starter on certain models. To activate this feature, press the button on the bottom of the fob until it sounds. Then, put the key into the trunk opener and pull it back 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 is an essential safety feature that helps to prevent car theft by ensuring that only the right key is used to start the car. It does this by verifying that the key's code matches the one stored in the computer. The engine will only begin if the codes match. This system has been in use for over 20 years and has contributed to decrease the theft of vehicles. This system is also an effective way to avoid hotwiring. Hotwiring is the process of bypassing ignition switches by connecting wires from the ignition coil to the fuel pump relay.
The immobilizer is a part of the key fob or key that contains a transponder chip. The chip sends a passcode to the immobilizer system of the car, which is built into the PCM, BCM, instrument cluster or smart junction box or another module. The immobilizer unit verifies the code and permits engine to start if the passcode is valid.
Modern transponder chips and keys employ a cryptographic algorithm to ensure that codes are sent only once, and only by authorized keys or key fobs. These algorithms are designed to be difficult for hackers to break. This technology also protects against remote key duplication which is common in the instance of stolen vehicles.
If the immobilizer cannot recognize the code on the key or fob it will sound an alarm. It will also disable the fuel pump, ignition coil, or injectors depending on the type of engine in your car. The engine will start for a few seconds and then die, making it impossible to drive your car away.
Immobilizers are an excellent security device that has helped reduce vehicle thefts through the prevention of hot wiring. It is not foolproof and a lot of thieves have discovered ways to take advantage of it. The Keylab involve using a computer to decode the algorithm. This can be done with a specific program.
Another method involves using a device to change the code on the transponder chip or key. This can be done by using a device called a "transponder reader" that is available on the internet for purchase. These devices aren't a reliable method of defeating the immobilizer, but they can assist in certain situations.
Replace the battery
If your BMW keyfob doesn't function like it once did and you're in need of replacement batteries. The good news is that replacing the battery in your BMW is an easy procedure, and shouldn't take more than 30 minutes. The first step is removing the key metal from the fob.

There are CR2450 batteries at most supermarkets and gas stations.

The battery isn't replaceable without cutting through the case. To do that you'll have to contact a BMW dealer.
Many BMW models from 2011 to 2017 use the sleek slant-shaped battery, which is also known as a watch battery. You can change the battery by pressing a button near the spot where the key pops out of its case, and then taking off the cover. There will be the appearance of a small groove within this opening. Utilize a screwdriver, or valet key to turn the groove counterclockwise to remove the cover. Once the cover has been removed, you can take out the dead battery and put in a new one.
The range of the signal on your BMW key fob is likely to decrease when the battery is not working. Normally you should be able unlock your car from between 30 and 60 feet. If you're not able to get closer than 20ft it's likely time to replace the battery.
A drained or faulty battery will also stop the remote starter from working. This is a critical security feature in a lot of automobiles, so you must change the battery as soon as you can. If you own a BMW equipped with a push button start, you'll need to go to the dealership to program the new key fob and sync additional fobs to the vehicle.

The Non-Comfort Access Keys, which were in use between 1996 and 2011 on a few X3 E83 models, use the key with a side-indent that is not able to be removed.
