Key Battery Replacement for BMW X3

Model: BMW X3 MK 2, F25 - Years 2010-2017
Part: Key

Press the button on the back of the remote to extract the manual key from the remote itself. Now insert a small screwdriver or any sharp tool into the hole left by the manual key and detach the upper cover of the housing. At this point, you will find the sought-after battery, which is a CR2450 and can be easily found at a hardware store or a large supermarket. Pry it out from underneath and insert the new one you purchased, then reassemble everything. The same key is used for BMW X5 vehicles.
