Is there a way to convince my van that it is not being stolen?

What is your question?

Bought van new in '01. Security lock out has been a problem since beginning. Shop said they couldn't find the cause if it was't broke when they check it. Dah!! Shop did play with wireing at bottom of steering column, but it didn't change anything. Used to be occasional, but becoming more frequent. Only 53,000 miles. Wait ten minutes and try again.
