one of your door switches, hood switch, or trunk switch is kaput.

each needs to make a positive connection (or disconnection) for the system to be able to arm.

In my case, it was a microswitch burried in the trunk lock that caused me similar symptoms. One of 2 plasic pegs had broken off an allowed the switch to rotate out of it's proper position.
