I had a pile of Mopar keys, it's one of those 'Pocket Pull' items you get while free roaming the junkyards. See a ignition key, pocket it, same with the trunk and I was kind enough to open the trunk and pop the lock cylinder out for the next guy that needed access to the trunk!
I had so many keys but not a complete 'Master Set' heh, but back then we didn't even know something like that even existed. But every new Mopar I got I matched several keys exactly with my spares, the trunk/glovebox key I don't think had many combinations and was a fairly easy match and some ignition keys would be close and with just a clamp in the vise and a little filing with a small 3 cornered file... BINGO! Spare key!
About the only time I got caught out with locking my keys in the ignition was one of the first cars I got with electric door locks. In a hurry one day I forgot something and in jumping out of the car my elbow hit the power lock locking the keys inside. The only delay was trying to remember what shoebox or drawer the spare keys were in, no biggie really it wasn't like I was going to be late for court or a doctors appointment. After that I just kept a set of car keys on one key ring with the house, toolbox, bike lock, etc and then the set I would use for the vehicle I was driving on it's own separate key fob. Big set of keys in the left pocket, working set of keys in right pocket. Bob's ur'unkle!
Only time that I can remember crawling through the back seat was a 'Damsel in Distress' type situation and IIRC the keys weren't in the trunk. You know one of them monster bottomless pit type purse deals. Then there was the Daytona Pit Man incident that led to a broken vent window (on the drivers side, idiot) but we try to forget those times.
