My Jimmy security system won't let my car start. This is happening just about every 3-4 days. Is there a fuse I can pull to disable the security system?

No,there is no way around your security issue,you may have to have truck looked at by a pro,ecm may need reprogramming or replaced.One thing to try,and may work or not,but leave your positive cable off,over nite,may help reset ecm,if you are lucky,,,Good luck
