2015 Mini Cooper Key Fob Battery Replacement

Introduction

If a key fob battery dies, you can no longer use it to open your car. This can be a hassle, as most modern cars either don’t have a manual way to do so or require a lot of hoops to jump through. Replacing the battery on MINI Cooper key fobs (in this case, a 2015 model, but this should apply to a range of years), though, is a nightmare. The intended way, using the key itself, does not have enough leverage to pry the plastic open without cracking the back plate. This guide goes over how to replace your battery without damaging the back covering.

Press the silver button on the side of the neck, and pull the key out.
Insert the key into the latch on the back of the battery casing, above the slot where it comes out. Pull up and out.
If the backing doesn't come out easily, take the key out and try again.
