Key fob issue

Henkan · 08-13-2021, 07:19 AM

Hi, I have an F12 convertible and one of the fobs is not working satisfactory. The remote unlocking feature does not work. I have changed the battery to no avail. It seems that the fob can unlock the car when placing it to the key symbol on the steering wheel column though.

I have tried to "pair" it to the car but it does not seem to work either. Although the guides I found were a bit different.

Any clues on how to proceed before I order a new fob from BMW?

I was getting the "Remote Control Not Detected" on the center screen. After a brief pause, and secondary start button push, it always worked. Installing a fresh high quality battery, did not fix the issue. Dealer told me I needed to buy a new key fob. Since I have two, I was not in any hurry to do that.

Recently, while swapping out my springs, I disconnected the battery in the trunk (to avoid any issues with the magnetic dampeners). While this project was completely unrelated to the key fob issue, I have yet to see it re-occur. Before the battery disconnect, it would occur 30% of the time. The battery was disconnect for at least 24 hours, though I would imagine less time would also work. This may be long shot for you, but it is easy to try.
