What Functions Does a BMW Key Fob Have?
If you own a BMW it is likely that your key fob is equipped with numerous functions. You can use it to unlock your doors, control your windows and even start your engine.
There are some tricks that you might not be aware of. Here are a few of the most effective.
Functions
The BMW key fob is a small rectangular piece of plastic that has several buttons incorporated in its side. Most of the buttons are used to lock and unlock the vehicle, and a few have more unique functions. For example, BMW owners can activate a hidden function on their key fob to lower all their windows simultaneously by pressing the unlock button two times. This is ideal for people who want to cool their vehicle on a hot summer's day.
Another important function of the BMW key fob is that it can be used to start the vehicle. This is a security measure to ensure that no one is able to gain access to the vehicle. To start the engine, the driver must press the lock button on the key fob, then press the circular arrow. For the latest BMW models the feature can be used to remotely start the car. This feature is particularly useful when the driver is running late to work and doesn't have time to open the door.
The BMW key fob is also capable of controlling the internal climate system. This is especially convenient for those who travel with multiple people, as it is possible to set each person's preferred temperature using their own key fob. The key fob on a hybrid BMW can be used to check the battery's charge status.
While the standard BMW key fobs can withstand normal levels of moisture, dropping them in water can cause serious damage. This is why it's recommended to keep the key fob in a protective case when not in use. If you lose your key fob we can provide a service that will disable the device, making it useless to thieves. Contacting the dealer or one of our technicians will do this. A replacement for a lost BMW key fob can be purchased to restore functionality to your vehicle.
Design
BMW key fobs were huge rectangular black pieces that looked like a bottle opener from the distance. They were simple, but functional. BMW then made them smaller and also added a plastic casing around the base to make it appear better and less like the key opener. The new design also trimmed rough edges on the keys that could poke into bags or pockets and made keys easier for you to hold.
BMW introduced the Display Key which puts all the features of your vehicle in your hands. It lets you lock and unlock your car, control your air conditioning, and display vehicle information on a small LCD touchscreen on the BMW key fob. Even hybrid models have remote parking!
BMW Digital Keys are a fantastic replacement option if you have to replace your BMW key fob. You can unlock your car using your smartphone provided you have a compatible model. This feature is only available on BMW vehicles built after 2021 that use the iDrive 8 system.
Another exciting new key from BMW is the Connected Remote Key that lets you start your car and operate some of its features with your smartphone. The app allows you to remotely manage your car's climate control as well as check the battery level and much more! You can also see how you've got gas left in your tank if the car is equipped with this feature.
Whether you're using a BMW Digital Key or a traditional key fob, the process of getting the replacement is the same. Our technicians will help you with the process when you bring your old key and new one to Patrick BMW. You can also purchase a BMW Key Protection plan, which will cover the costs of a replacement if your keys are lost or stolen.
If you do lose your BMW key, don't panic! The first thing to do is reset the key. This will erase all programming and render it useless. This is accomplished by turning the key to position one and back in quick succession five times in one row. Then, turn it to zero and then take off the ignition.
Security
The BMW Digital Key makes it easy to start your car. The fob is compatible with your Apple Watch or smartphone and is compatible with BMW Connected Drive. It can unlock the vehicle and then start the engine. You can also share the key with five other people.
The key fob communicates with vehicle via encrypted signals. This makes it difficult for hackers to steal and clone the signal. The UWB technology of the BMW Digital Key also prevents relay attacks even if it is moving. The system also has an inbuilt alarm system to block unauthorised starts and disables the ignition switch which is a frequent target for thieves.
BMW offers a range of optional security features. Passive Start is one such feature that will disable the starter motor if the key fob doesn't remain within close proximity to your car. This feature is available on many BMW models and can provide additional security.
BMW's more sophisticated models include keyless entry that allows users to start their car without having to manually insert a key or push any buttons. This feature is usually activated by pressing the lock button on the fob three times within one second. In some cases you may need to press the lock on the fob 3 times in order to activate a remote start feature on the dashboard or steering wheel.
Some people carry their BMW key fob in a case that blocks signals. This minimizes the risk of a third-party broadcasting identifying code from the fob to gain access to the vehicle. Some prefer a standard key case, that does not come with this feature, but it will protect the fob from scratches.
Some BMW owners have reported that their vehicles were taken by criminals using an amplifier for signal strength to boost the identifying signals. This type of attack is known as "Relay Attack" and can be prevented by keeping the key fob in a signal-blocking pocket or by installing an app that blocks signals on your phone.
Replacement

Depending on the model of your car, you might either have a key blade here inside your key fob, or that isn't. Each fob has a different process to sync with your vehicle, but the steps for each are almost identical.
