It sure seems like some days everything that can go wrong will.
I carry a spare on a separate set of keys in my pocket. I also have one for my wife's truck on the same key ring. I also have keys to the front gate to the ranch on the same key-ring even though my ranch keys are on the same key-ring as my truck key. :lol: Redundancy seems silly until you're in a position where it saves your butt.
damned electric door locks have me carrying multiple keys....but i am now in the habit of locking my truck everytime I exit it as I usually have a gun or three in there.....
