BMW Key Fob Battery Replacement & Disassembly (VIDEO)



Video tutorial on how to disassemble a BMW key fob for button and battery replacement. This particular remote is from a 1997 BMW 540i, but it found throughout various BMW models and it changes slightly a couple years newer as it’s equipped with an LED, but the procedure is basically the same. Buttons can be purchased at aftermarket retailers such as Amazon or eBay. This particular remote takes 2 CR1220 batteries. I believe the newer version of this remote takes a single CR2016. If someone can confirm this, that would be greatly appreciated.

Tools/Supplies Needed:
-two CR1220 batteries or one CR2016 battery
-phillips screwdriver
-standard/flat screwdriver
-new replacement buttons
-knife

Procedure:
-first start by removing the small plastic cap covering up two phillips screws on the backside of the case using a small standard screwdriver
-next remove the two small phillips screws.
-now remove the backside of the case which will expose the internal components
-this particular remote takes 2 CR1220 batteries
-next use a standard screwdriver to pop out the internal components
-there will be a small transponder as well, do not loose this
-remove the old buttons, they’re actually moulded within the case, so technically they’re not supposed to be removable
-you’ll have to push them through the front side back, even using the assistance of a razor knife
-be extremely careful not to break the plastic frame around the button edge
-you’ll have to clean these holes, just helps prevent any installation issues with the new buttons
-for the new buttons, you’ll also need to trim enough space for the transponder and there is also a component on the circuit board which needs to have a spot cut out for on the button pad too
-make sure you cut enough rubber out so it doesn’t deform the button pad, but not too much where it jeopardizing the structure of the button
-push in the new button pad, you’ll need to slowly push it from the backside out to the front, pulling it from side to side, and careful not to scratch the finish on the new buttons from the plastic case
-ensure it’s seated correctly and then you can install the transponder and finally the circuit board assembly
-install the rest of the components in reverse of removal
