    Hey all -

    I have a Gen2 Prius in UK and all of a sudden have the following issues:

    • The key fob does not lock/unlock the doors
    • when I used to leave the car unlocked before, it used to auto-lock after a few mins. This is also broken
    • When I put fob in the slot the car starts and all works fine.

    I have changed the key fob battery and have tried a second key also but still no difference. Any advice please, I do not want to be spending big money on fixing this as it is an old car...
