While messing with the truck yesterday, I realized that the only usable key is a little tweaked and cracked. I went to a locksmith today to see if they could copy the key before it bent worse or broke, like the other two surviving truck keys.
They pressed the key in a vise to straighten it and then they copied it easily. The copies look great, but I'll have to make sure they work on my next trip out to the farm.
Once the truck is home, I plan to install a new ignition switch and door locks. But until then, I need a decent key so I can start her up again. Maybe Saturday.
