Weird charging problem. Or maybe not?

[Refueler]

Maybe the village idiot could, but I've sailed with intelligent people who couldn't. My last boss, an extremely competent deputy director of finance for a large NHS trust, freely admitted that, with a screwdriver in his hand, he became a public danger.

I have a pal like that ... extremely intelligent .... but woe betide any car that becomes his !!

I lent him a car for about 7 - 8 months. Opel Zafira .... with the strict instruction that he was NOT to try and fix anything on it ... any fault etc - call me and I'll get it fixed by Car service ... he laughed and agreed !!

I got car back .. ignition key unit in steering falls out now if not careful. There are now two Fobs needed and two keys needed ... one key to lock door - other key to start engine ... one fob to remote lock car, other fob to remotely unlock car ...
Basically according to him - the ignition unit came out of steering and he lost it walking away from car ... reckons it must have been on the key and fell off !
He got another ignition unit and tried fitting it himself ... so now I have the above mess !!
