trying to figure out why my 1999 accord EX antitheft alarm system keeps self-alarming ? I have to leave the doors unlocked or it triggers and have to use the key unlocking the door to terminate alarm.

Is there a Code readable from the blinking "red" alarm leds in the door and radio face plate that tells what's happening?
