I Have a 67 Camaro it has everything original but isn't fully restored. THe only thing thats wrong with it now is that everytime I lock my RH side door i can't get it open with the key. I've tried by pulling the inside lock and no luck. I finally got it opened today and i just can't figure out why it's so hard to open by hand or by key. Would anybody have an answer to this. Or know why it keeps doing this.

Sounds like you are going to have to pull the door panel and stick your hands in there. Could be a loose/detached linkage from the cylinder to the door lock mechanism.

common problem, you need new inner door latch springs... , just replaced some on a customer's 69
rick's sells them under $10 for the pair
left DH-26
Rh DH-27

thanks i'll take the latch out and check the springs tomarrow is it easy to install or replace the springs on the latch?

Yep, once you figure out the orientation of the spring. I'll look and see if I have a pic and post it
