How do you disconnect security system for 1999 Chevy 1500 4x4?

Answer 1

Sounds like it won't start ???

If it won't try this, It will take 33 min. to reset the security system, if the system is working fine.

Now read closely. Remove the security fuse in fuse box and make sure it is good to go. if it is put it back in. Open door and there is a cover on the side of dash, pop it off and that is the fuse box.

Now get a watch, First step. Now turn the key to start mode and as soon as you hear the starter ingauge turn the key loose not off, just turn it loose. Wait 11 mins. only

no more and no less 11 min only. After 11 min. turn key off and repeat the same

steps 2 more times, do not wait. After the last 11 min or up turn key off and then start truck. Each step should be 11 min. only and that makes 33 minutes.

Make sure your in the truck and doors shut.
