problem: key won't go into the ignition lock

It's becoming  difficult to get the ignition key into the ignition
lock. Key turns fine when it goes in, but sometimes it'll go in and
sometimes not. Irritating.

May be something to do with the fact that the van was stolen a year or
two ago, and the thief probably started it with a screwdriver. At any
rate it feels like one of the little thingys that should be pushed
aside by the key as it goes in ( I don't think it's a tumbler ) is
occasionally getting stuck and not letting the key in. And more so
recently.

I think it's something on it's way to gettting permanently
stuck/broke...know what I mean?

Anyone taken apart the ignition lock recently? Anyone got any suggestions?

I'm off to get some graphite to see if that's the simple/cheap answer

I haven't tried the archives- no access at the moment
