My X308 is off the road at the moment and has been since 1st April 2022. I have a Ctek charger fitted to keep the battery charged. When i went to get into the car yesterday, the central locking failed to work. I had to use the key in the drivers door to get into the car. I started the car and left it running for half a hour before the central locking worked. All doors (except the drivers door) and boot failed to open until the remote began to work. Has anyone had similar experiences?

 

Not personally, but from what others have posted, the simple solution was a hard reset.
I attached a PDF describing the procedure, starting on Pg 5.
