new k5 some help?

[msblackbetty79]

well today i bought a 1989 k5 chevy. awesome truck very strong motor and trans! well i tried to roll the window down and come to find out looks like the key is missing! so i cant even use the tailgate! such a bummer. anyone run into this problem before? and should i call out a guy to pick the lock, or is there a way to replace the whole assembly?

one more question, should it be the same key that id use to unlock the truck doors?

will post pictures in a day or so!
