Types Of BMW Key Fobs

When it comes to BMW key fobs, there are various types available depending on the model and features of your BMW. Each key Fob offers different functionalities and convenience for the car owner. Let’s look at two popular types: diamond-shaped key fobs and comfort access key fobs.

Diamond-shaped Key Fobs

The diamond-shaped key fobs are the most common types used in BMW vehicles. They have a sleek and compact design that fits comfortably in your hand. These key fobs have a traditional key format, allowing you to manually unlock and lock your BMW. The diamond-shaped key fobs may also have basic buttons for remote locking and unlocking and a panic button for emergencies.

The diamond-shaped key fobs are generally used in older BMW models and may not have advanced features like keyless entry or push-to-start buttons. However, they are reliable and easy to use. If your BMW has a diamond-shaped key fob, you can easily replace its battery by following simple steps.

Comfort Access Key Fobs

Comfort access key fobs are a more advanced type of BMW key fob that offers enhanced convenience and security features. These key fobs are designed with a push-to-start button, allowing you to start your BMW without inserting the key into the ignition. They also feature keyless entry, which means you can unlock and lock your BMW by simply having the key Fob in your pocket or purse.

Comfort access key fobs use radio frequency identification (RFID) technology to communicate with your BMW. This technology enables the key Fob to be detected by your BMW’s sensors, triggering the automatic unlocking or locking of the doors. It provides a seamless and hassle-free experience for the car owner.

If your BMW is equipped with a comfort access key fob, replacing its battery is straightforward. Locate the battery compartment on the key Fob, remove the old battery, and insert a new one of the same type. It’s essential to ensure the orientation of the battery is correct before reassembling the key Fob.

Whether you have a diamond-shaped key fob or a comfort access key fob, checking the battery level and replacing it regularly is essential. A low or dead battery can cause inconvenience and, in some cases, may prevent the key Fob from functioning correctly.
