factory security system

[86bluet]

My factory alarm acts weird when you lock the doors, does anyone have a schematic on the system and how to bypass it. Do the door locks cylinders have a activation switch on them?

Do the door locks cylinders have a activation switch on them? Yes they do.

thats not good

Thanks, I was afraid of that, can you buy replacement lock cylinders with the switch on them? Mine is missing someone else wanted it more than me.

I believe they have been discontinued however you can get used from G-Body
Parts. Remember GM made keys in different lengths. It might help to send your old lock in. Remove your lock and see if just activator can be replaced
i wasn't as lucky.

The lock cylinders have a clip that is part of the security system as well as a piece at the end of the lock that moves when the key unlocks the door. It's a two piece system on each lock cylinder.
