F80 - X5M key fob mod
I'm not a fan of the popular BMW key fobs used with the F8x and F30x.
I much prefer the X5m key. So I bought a used X5m key on ebay with the hopes to swap out the internal circuit. Unfortunately, the internal circuits were too different and incompatible to be modified to fit the smaller X5m key fob. Has anyone had any luck in ordering an new X5m key from BMW and have it keyed and coded for their car? |

That other thread, the guy basically removed one of the chips on the board to replaced it with the the chip from his m3/m4 key. You need specially tools like a reflow station.

Just a heads up, but X1 models have the same FOB in case anyone is looking to do this mod.

Don't know but key fob sucks.. i am sure if someone set up a business for making better key fobs for m3/m4 they would be doing well .

Yes we have an update!
A big shout-out to knightarmor who helped immensely last weekend on this project. On a previous thread, it was reported that the IC to swap was the little square 64pin IC. We swapped the two ICs and found that was INCORRECT. After some online research and testing, we confirmed that this 64pin IC (shaded in red below) is actually the remote transmitter IC. We tested this by using my original 2018 F80 key with that IC removed from the key fob board. The remote buttons would not work but when placing the key against the steering column, the vehicle started up. Conversely, the re-installed F80 64pin IC onto the X5M key did not work (remote unlock or vehicle start-up). As it turns out, the longer rectangular IC (highlighted in yellow below) is what actually contains the vehicle code and driver data. Unfortunately that IC on my 2018 F80’s key fob contains 28pins whereas that IC on X5M key fob I purchased on eBay has 38pins. Therefore, we were unable to do the swap. From what I can tell on eBay and RealOEM, there are a few X5M keys available, all at 434 MHz. The part number of the X5M key tested is 66129367403. RealOEM references 3 other related keys (listed below under Group 1). I came across another X5M key on eBay (part number under Group 2 and two other compatible keys per RealOEM). I am still quite keen on this mod but would appreciate any input from others. Specifically, Im needing to find out which X5M key fob (ie part number) has a board that uses the 28pin IC. Group 1 66126806000 12/01/2015 - current 66129367403 08/01/2013 - 02/14/2017 66129337246 08/01/2013 - 05/01/2015 66129317138 08/01/2013 - 08/07/2013 Group 2 66126805992 12/01/2015 - current 66129367395 08/01/2013 - 12/01/2015 66129317147 11/01/2014 - 04/24/2015 Last edited by Zermatt; 03-06-2018 at 04:34 PM.. |

I might be able to get a used X5M fob and open it up to verify the chip. Stay tuned

Maybe the version that has silver buttons like the one in this thread will work: http://f30.bimmerpost.com/forums/sho....php?t=1331334
