Why We Why We BMW Keys (And You Should Too!)
Troubleshooting Problems With BMW Keys
Up until the i8 and 7 Series, BMW keys were quite clunky black plastic rectangles that had to be inserted into the ignition slot to unlock and start the car. However, that all changed when the digital keys came out.
However, can it be hacked? And can you use a keyfob that isn't genuine to activate Comfort Access in your BMW?
Keyless entry
If you've been driving a BMW for some time you're probably familiar with remote start and keyless entry. These features are easy to use and also ensure that you're driving safely. You can also lock and unlock your car from the at-home comforts of your home provided you have the appropriate apps on your smartphone. These key fobs aren't without flaws, just as with any new technology.
Some BMW owners wonder about, for example, whether their key fob could be compromised. BMWs are designed with security in mind, and therefore they're almost 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 a signal amplifier to gain access to your vehicle.
Another issue that people ask is whether or not the BMW fob will go to sleep. The fob will go to sleep if it's not pressed for a set amount of time. This can help conserve battery power and stops the car from opening uninvited. However the key fob will still work in the ignition if it is repeatedly pressed.
In addition to keyless entry, the BMW key fob can also lock and unlock the car, or turn on the automatic transmission of cars with manual shifters. The BMW key fob can also be able to control certain aspects of the car's comfort features like seat, mirror, and adjustments to the steering wheel. It can also save personal settings, like presets for the radio and seat position and permit owners to unlock their BMW through the MyBMW app on their smartphone.
BMW key fobs can be used to unlock a trunk or activate a push-button starter on some models. To activate this feature, press the button on the bottom of the fob until it tinks. Insert the key into the trunk opening, then pull it down to unlock the trunk. The BMW key fob also has the capability of controlling the vehicle's media system as well as climate control.
Electronic immobilizer
The engine immobilizer is an essential security feature that helps protect against theft of cars by ensuring that only the right key is used to start the car. This is accomplished by using the code on the car's key to the one stored in computer. The engine will only begin when the codes are identical. This system has been in operation for over 20 years and has helped 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 a component of the key fob or key that has a transponder chip. The chip transmits a passcode to the immobilizer unit of the car which is embedded in the PCM, BCM, instrument cluster, smart junction box, or any other module. The immobilizer unit checks the passcode and allows the engine to start if it is correct.
Modern transponder chips and keys utilize cryptographic algorithms to ensure that codes are transmitted only once, and only through authorized keys or key fobs. These cryptographic algorithms were designed to be difficult to crack by hackers. This technology also shields against remote key duplication, which is a common case of stolen cars.
If the immobilizer does not recognize the code on the key or fob it will sound an alarm. It will also shut down the fuel pump, ignition coil, or injectors, dependent on the type of engine in your vehicle. The engine will run for a short time, then shut down. It's impossible to leave the vehicle.
Immobilizers are a great safety device that has helped reduce vehicle thefts by preventing hot wiring. It's not foolproof, and a number of thieves have found ways to take advantage of it. Some of these strategies include using a laptop to decode the cryptographic algorithm, which can be accomplished using an application that is specifically designed for this purpose.
Another method involves using an instrument to alter the code of the transponder chip or key. You can accomplish this by purchasing the "transponder-reader" on the internet. These devices aren't a reliable method of defeating the immobilizer, but they could help in some cases.
Replace the battery
If your BMW key fob isn't working as well as it did in the past it, you might need a new battery. It's simple to replace the battery in your BMW and shouldn't take more than 30 minutes.

There are various ways to change the battery depending on the type of BMW key you own. If you have a BMW Smart Key it uses an automatic battery that charges when it is inserted into the ignition. This battery cannot be replaced without cutting the case. You'll need to call your local BMW dealer.
Many BMW models from 2011 to 2017 utilize the sleek slant-shaped battery, which is also called a watch battery. The battery is replaced by pressing a button near where the key flips out of the case and removing it. There will be an opening with a small groove in this opening. Use a screwdriver or valet key to turn the groove counterclockwise until you remove the cover. Once the cover is removed, you can take off the dead battery and put in a new one.

A damaged or depleted battery will also prevent the remote starter from working. This is a crucial safety feature in many automobiles, so you must change the battery as soon as possible. If you own a BMW with push button start, you'll have to go to the dealership to program the new key fob and then sync additional fobs to the vehicle.
Replace the key
BMW is a luxury automobile manufacturer that offers various models, each of which has distinct features. They are renowned for their style, comfort and performance.

Based on the model of your vehicle, there are a few different kinds of BMW key fobs. The latest ones use Smart Keys, a device that is more advanced and can secure your car and unlock it. These are usually more reliable than the older BMW keys, but the battery will need to be changed when it dies.
Older BMWs that are still being parked in Decatur may use a Bladed Key, or a Non Comfort Access Key. The Bladed Key is a metal key that is inserted into an ignition. The Non-Comfort Access Keys, which were in use between 1996 and 2011 on certain X3 E83 models, have the key with a side indent that isn't removable. To change the battery in this type of key, you'll require an open screwdriver to remove the case and remove the dead battery.
The next step is to put the battery replacement into the clip or holder. You must also be careful not to scratch the plastic of the key fob or the circuit board within.
