Hello. I have what I hope is a simple question. I want to make a key for a door lock in an 88 GM truck. I have the decoder gauge but what is the procedure to decode the lock? The lock is already removed. Do the tumblers have to be in alignment with the sidebar before decoding i.e. as if the correct key were in it? If so what is the best way to accomplish this since I don't see anyway to put pressure on the sidebar to pick them into place. Also what is the progression for the spaces unreadable with the decoder? It really isn't feasable to call a locksmith where I'm at since the nearest one is many miles away so I would greatly appreciate any assistance. Please respond on the newsgroup since my email address is not given to avoid getting tons of spam.
