Morris Minor Owners Club

The thread on my ignition switch has worn to the point that the chrome nut fell off as I drove it last week.
I got a replacement on fleabay and fitted it this evening.
I was wondering how hard it would be to swap the barrels to let me use the two nice new keys I had recently had cut for the old switch.
On a whim I tried the old key in the new lock, the profile was very different between the two keys.
Works a treat!
Not very secure but I'm pleased!

Not hard. IIRC there is a small hole in the side of the housing. You put the key in, push a pin into the hole, and use the key to pull the barrel out. I can't remember whether you do this with it turned to the 'off' position or the 'run' position, but one or the other should work.
