It is really hard to follow the logic of some of the installers. I owned a relatively high end Stereo / Alarm store here in St Louis in the 80s and the alarms were always a PITA. We constantly got in cars that had aftermarket systems that we had to diagnose. Normally we simply removed them and put the car back to stock, especially for the dealers. We serviced the 2 Porsche dealers here as well as the BMW and M/B stores. Those guys really hate these systems and would not touch cars here that had them.

You may even have an ignition switch problem if you can get it to work intermittantly with the key. The best place to start though is bypassing the alarm.
