There is a number on the lock inside, secret disassembly steps required if you lost key and didn’t write it down
It’s 4 digits
Canada and USA share the same lock number lookup table
With those 4 numbers your locksmith can cut a key without seeing the lock or the truck
My local locksmith took apart a glove box and ignition lock for me in Canada
Emailed a guy he knows in the USA who looked up the key machine settings for him and he produced a perfect key for my grandpas old farm truck.
