E91 key help. Please
Hi guys.
I have had a work van for the last few weeks so car only used on weekends. My other half used my main key to take the child seat out 2 days ago with no issues. However i have come to unlock the car tonight and the unlock/lock does not work from the remote! Starts the car fine. My spare key that had not been used for a few months works perfect on locking and unlocking as well as starting. Any reason 1 key would just stop? Tried searching but maybe looking wrong. Module must be ok as spare works fine. Is there a re sync process? All help appreciated. Thank you Posted here too as maybe a bigger audience Last edited by Msportshqwn; 11-14-2018 at 03:36 PM.. |

If you have comfort access have you tried changing
the battery in the Fob (cr2032 battery) With comfort access the key doesn't have to be in the ignition and you can lock and unlock the front doors by handles. If not comfort access |

Hi.
It does not have comfort access. And is the block type key that slots in the dash. Really strange main key just stopped. Not sure if there is a re sync method. Seeing as other half only went in the car 2 days ir so ago. Cheers for the reply |

Did somebody wash it maybe.
The auto parts stores around here have remote tester than can detect a radio signal coming from the remote when a key is pressed I would suggest that as the first test. If you can find a place that has the tester. No such thing as a rsync that I know of. https://www.e90post.com/forums/showthread.php?t=1510527 https://www.bimmerfest.com/forums/sh...d.php?t=903551 |
