Recently my accords alarm system has been going off constantly for no real reason. The car doesn't even need to be locked.The doors can be wide open and it goes off. The only way to stop it is by putting the car in the on position. It used to stop after letting it sit for a while but after 30 seconds ( if that much) it comes back on. Only temporary solution I found was to disconnect the battery. Any suggestions? I'm just trying to get the car to last long enough for me yup get a new one.

 

Disconnect the Hood switch.. Then the alarm wont be able to "arm" itself

 

It's possible that the alarm system is grounding out somewhere.
