Re the door lock....a friend had similar with his. It was the battery in the key fob. A new battery and it was ok.

My Plus Four had a failure of the gauges in the dash. Just the round gauges as the LED screen was ok. I knew my speed and the warning lights seemed ok. I used the Morgan recovery to get it from home to the dealer. Recovery vehicle arrived in less than 2 hours. Dealer sorted it with a new pcb.New pcb came from the factory within a couple of days and fitted promptly. I caught a train to a station a few minutes from the dealer who picked me up there. Train journey was nice. Haven't done one for a while, apart from a "sardines in a tin" one going to Cardiff due to rugby matches there.
