I end up jamming buttons until it eventually does. I have tried the trick with manually unlocking the doors and everything and the only thing that works is jamming random buttons. I was going to try to pull the fuse but I cannot seem to find it.

Hello,

It sounds like you may have a BCM that is going out. if you pull the fuse the engine will not start so it must be fixed.here is the BCM location and the security system wiring diagrams so you can see how the system works and the BCM location which I would check the connector for corrosion. If the BCM is bad it will need to be programmed to the car it should cost about $130.00. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
