So, this truck… Realized some time ago that I couldn’t get the tranny out of park (automatic) and the reason was connected to the ignition core for the key. I replaced the core. When I re-connected the battery, even with the key in the new ignition core, the alarm sounds, and I cannot get the truck to start with the key. Help? I’m going deaf here… ---

Is this a factory or an aftermarket alarm system? If it’s a factory system see a knowledgable independent mechanic. If it’s an aftermarket type have the mechanic remove it. Aftermarket alarm systems are almost always…junk. They will cause the problems you are having as we speak. ---

It is a factory alarm system. I was hoping I could figure it out myself, as the nearest mechanic is a five hour drive from the house, and I can’t drive the truck there because it will not start- it would be a very expensive tow!
