[T2] Key Won't turn

[Steve]

The ignition lock in that van is serviceable.  There are a number of aftermarket switches available if that is the problem.  There are also some aftermarket ignition locks available, but they use a different type of key that cannot be matched to your existing lock.  On a good note, I've only run into 1 ignition lock of that type that I couldn't resurrect.
