Rover 75 Key Fob Stopped Working
Hi guys,
So after driving my lovely Rover 75 for some months with zero issues i had to discover my key not working earlier today. I first thought its a battery problem so i drove home just fine changed the battery and nothing. I pressed the keys multiple times, helt the keys down, started the car and tried the same, opened and closed all doors just to make sure they are closed correctly. But sadly nothing helped. Does this seem to you guys like a broken key or maybe a sync issue? I tried looking up ways to sync but nothing seems to work. All doors open / close just fine using the lock. I also took the new battery out for some time and put it back in to make sure it fits correctly. The chance its a dead battery is quite small tbh and the old battery showed no signs of being empty prior to today. Any tips or links to a quality replacement dealer are appreciated |

The micro chip in the key is very small and can easily fall out while changing the battery.---

I'm guessing we're talking about the remote operation ...
A member here in Sweden had the same problem a few days ago. Tried the sync procedure as per handbook, didn't help. Then tried what he referred to as a "Norwegian re-set": took one of the cables off the main battery and held it briefly against the other. Tried the sync procedure and it worked. First time I've ever heard of it. Otherwise people tend to recommend a main battery disconnect for half-an-hour, if that fails then Toaf can reactivate remote boards. Regards |

Sounds like we are having the exact same problem ( and we do not have a spare remote..) I will disconnect the car's battery tonight and see if the 'turn it off and back on ' fix works EDIT: disconnected car battery -ve for 30 mins, sync key ( pressed lock 4 times quickly ). Remote still does not work. Holding down either lock or unlock button the light flashes- this is normal?

First I would open the case and make sure that the open and close switches are still in place. In one of my keys the open one was loose. Had it soldered and working fine now.

This might sound daft but have you tried driving to another location and trying the key again ? This happened to me a few years ago when my remote function stopped working at home but when I later went to the shops it was fine. I came home and it stopped again ! This went on for a couple of days before righting itself. My only thought was signal interference from some source such as phone mast or remote doorbell close to my drive ?
Anyway it never happened ever again ! |

Thank you guys for the answers but sadly nothing helped so far.
My GF had a spare key which she tried yesterday but it also didnt work (her key is way newer and worked before) which makes me think its one of these 3 things: 1. The car forgot its own unlock key / reset the key to something else. 2. The chip is stuck here a fuse pull or battery removal might help (will try that this weekend). 3. The chip inside of the car broke its "wireless" function which just means its not going to work anymore. I will try pulling the fuse on friday when i have a little bit of time, i will also have to create a new post for that as i have no idea what fuse to pull lol. |
