Anti theft 2005 dodge ram 1500 will not start

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. A factory installed antitheft system will not cause this to happen. This makes me think that some added on device, an aftermarket alarm for example, has been installed and is malfunctioning. This necessitates some hands on testing to see what is happening in the system. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
