[V8] V8 Locks

[Scott Simmons]

Hey folks, has anyone here ever had any trouble with the power locks 
locking themselves?  As the weather hits the single digits, I plan on 
letting the car idle for 5-10 minutes before I leave work at night to 
warm up the engine and the cabin but I'm a bit leery about the power 
locks.  I know some other marques that use vacuum locks have them lock 
themselves if you look at them wrong.  Anyone had any issues?  
Currently, when I leave the car to idle, I take a spare key in with me.
