I have only locked my keys in the truck just once. But It wasn't really a problem because it was a old 1987 truck. The back window didn't latch, so I opened it, reached down behind the seat for the tire iron I always keep there, and used it to reach & pull the keys out of the ignition. No problem right? I was stopped four blocks later by the the cops because a guy in the parking lot who watched me break into my own truck, reported that I stole it. Since my license & registration matched, the cop let me go.
