The car alarm go's off completly random time. Some times a few min after locking some times a few hours. I have checked all the doors and the trunk and hood nothing wrong with the latches. I can not make the alarm go off. I pull on the handles nothing go's off. I pulled on the trunk nothing go's off. I bump the car nothing go's off. I walk away from the car the alarm go's off. It also go's off every 30 min at 3 am. I see there are a lot of people with similure issues but not a way to fix it. They said possibly battery but not all said that. Is there a way to find out with out just replacing one thing after another?

It could be a bad switch. Either a bad hood switch, or a bad door switch.

When driving, does the car think a door is open sometimes? If not, I would assume it's the hood latch switch which is a common culprit.
Also, does your car honk when you click the lock button on your remote twice?

That aside, you should check the switches on the hood and trunk. Remember the alarm is just a circuit and when opened/broken the alarm will sound. Not sure if the TSX is the same as the TL (likely is) but the radio and ignition are part of the circuit as well as the engine hood, trunk and four doors.
How old is your battery? Dead or dying batteries have been know to manifest themselves in lots of odd symptoms.
