DIY: Make your key FOB look new! Replacing your Key FOB Housing (Non-CA or CA)

Lightbulb DIY: Make your key FOB look new! Replacing your Key FOB Housing (Non-CA or CA)

How to: Replace your BMW key fob housing and make your key look like new!


While this guide is very simple, I posted it because there was a lot of uncertainty on the forums as to whether or not this can be done, so I wanted to document once and for all that it can, and very simply. I also wanted my first thread to be of something useful and to contribute to the community


Step 0: Buy a FOB housing. This is pretty simple, I got mine off of ebay for 25 dollars, I'm not sure if its okay to put a link, but for me searching "key fob housing e90 bmw" or some combination of those keywords worked for me.


Step 1: Bring out the disgusting fob whose housing you want to replace, here's mine:



Step 2: Remove the key.

Step 3: Using a flathead screwdriver, pry the case open in the same spot shown in this picture:


Do not be afraid to go inside that little hole and pry from there too, for me, it popped right open by prying it there.

Note: If you are having trouble DO NOT PRY inside the keyhole aiming towards the top of the fob (side with buttons) aim it down, as there are electronics above. Be careful when prying anywhere else but the spot shown in the picture. I AM NOT RESPONSIBLE IF YOU DAMAGE YOUR FOB.


(The case cracked open)

Step 4: Remove the circuit board.


Step 5: Place the board into the bottom half of the key fob, making sure that the 3 little indentations (one on the bottom two on the top) line up properly.


Step 6: Snap the two halves of the case together and enjoy your new key!

Welcome! I was nervous to try as well as it has only been discussed on the forum with no one really talking about doing it, but as it turns out its pretty easy.

My fob is just a little faded but the buttons look good. Will armor all or a similar product make it look better without having to take it apart?

Looks like an awfully big circuit board for very little in the way of components. Looks like you could make one the third of the size...

Someone do it so I can implant it in my hand. Or maybe just carry it in my wallet.

Just did this today, easy as can be. Thanks!

Update - the key FOB I bought off of eBay doesn't fit perfectly into the slot. The BMW center logo/lock button protrudes out more than the OEM keyfob did so I have to force it into the ignition, then do a shimmy-shake to get it out. The DIY guide is great, but the product I chose is just OK.

Where did you buy yours from? Some people posted theirs didn't fit perfectly, if yours did, could you post details on your seller? Thanks
