here's another "lock out"--your gas cap,does it have a lock? does everyone who drives that car have a key or know where it is hidden in the car..i say this because--ya...i took off all the extra keys on my ring before i went on a two week canoe trip to cut down on the stuff i would have tucked away in my pack--id,cell phone,credit card,all the "real world" things..and yes when i swapped off keys onto another ring i just put on the car and house key..250 miles on the road i pulled in to top off the tank before heading down the trail to the canoe landing and no gas cap key....
well i ripped the cap off with a screwdriver explaining to some folks gassing up there powerboats what a dope i was to forget the key--so on--lucky that little town had a place to get a new cap..
