Hi David. I have only had one fob at any one time while trying to sort this out . Today I went and did the same checks as I did on Monday. Re checked all the fuses both inside the car and under the bonnet and then tried to re educate the fobs using Pscan . Nothing has changed so I bit the bullet and removed the scu and sent it along with the fobs for Paul Brown to work his magic . My only area of concern is that although I have managed to release both door locks , the door handle lock will not fully turn in either direction and I have checked the lock is not siezed up it is as though the latch mechanism or the rods that go to the lock is jammed in some way. All I can hope is when the scu comes back and is plugged in it will cycle the lock back to neutral.
