Different Methods for Opening a BMW Key Fob

There are a few different methods for opening a BMW key fob, depending on the model and year of your vehicle. Some key fobs have a small release button or slot, while others require a small flathead screwdriver or similar tool.

Using the Release Button or Slot

Many newer BMW key fobs have a small release button or slot located on the side or back. Pressing this button or inserting a small tool into the slot will release the emergency key blade. Once the key blade is released, you can use it to gently pry open the two halves of the key fob casing.

Using a Flathead Screwdriver

For older BMW key fobs or those without a release button, you’ll likely need a small flathead screwdriver. Carefully insert the screwdriver into the seam between the two halves of the key fob casing. Gently twist the screwdriver to separate the two halves. Be careful not to apply too much pressure, as this could damage the casing.
