Ok I’ve done some fault finding and I’ve realised my actuators / solenoids are all working perfectly.
I have seen on my key lock mechanism that a clip which holds the lock rod has broken. There is also what looks like a very small grommet which looks like it’s slipped down the rod from where the lock barrel turns. This has made the mechanism loose and wouldn’t trigger the solenoid.
I have attached a picture of the broken clip (green arrow).
Does anyone know where I can get one of these? Or is it a whole door lock unit I have to buy?
