Year: 1992
Cleverly the previous owner snapped the door key in the door on the driver side, luckily it unlocked before snapping so I can still get into the car. But I’m just wondering how to get the lock off to replace it. I’m in a similar situation with the fuel filler cap and now can’t get this off either.

I’m not actually using the car on the road at the moment as I’m not 17 yet but I would like to get the lock situation sorted so I can actually fill it up when the time comes and lock it when I’m out and about.
All I would like to know is how to get the fuel cap off and door locks due to snapped keys.
Thanks in advance
