When the alarm system goes off at random times it's going to be one of the alarm triggers. The triggers that cause your problem are the doors, hood and trunk. If one is adjusted too loose it can set off the alarm causing a false security system breach. Each has a switch built into the latch or in the door way like the dome light switch. The Honda dealer can use the Honda HDS scan tool to check the breach history record stored in the security system control unit. Sometimes you can set the alarm wait several min then press out on each door from the inside. If the alarm goes off you found the door that needs to be adjusted. Also try pulling up on the trunk lid when the alarm is set it might need adjusted too? If none set off the alarm it's probably a bad hood latch switch. It's a very common Honda problem. Hard to give an exact answer in this situation. The dealer would be able to find the problem for sure with the breach history.
