Late last year the original fob again started operating only intermittently. Usually it would lock the vehicle after exiting and would not open it immediately afterwards. I decided as I had already soldered a new battery on it and had managed to kill one other PCB when soldering that I would order a new PCB to replace this older one. With the busyness of the end of the year it didn't get here before I left on holidays and I didn't have the time when I got back in early January so I only put it into service on Monday evening.

HOWEVER... the new PCB in the second remote stopped transmitting altogether last week. I had a spare case so last night I changed the battery in that. When I opened the case (buying that Dremel was a stroke of genius ) I found that the battery +ve pin had snapped - due in part as the the battery was not in a holder. At least I know now.

Surprisingly I tried using the remote to open the vehicle so that I could re-learn the keys with the Nanaocom and it actually worked.
