2015 Honda Accord security system fails and battery drains

My 2015 Accord will not engage security system when pressing LOCK button on any key fobs.
The doors do lock, but Horn does not sound nor do running lights flash when hittting LOCK button on key fob.

I probably can't help, but I think everyone will want to know whether it's a 4-door or 2-door, 4cyl or V6, LX, EX, etc...

The security control unit must receive signals that the doors, hood, and trunk lid are closed and locked. If one of the switches is misadjusted or there is a short in the system, the system will not arm. As long as the control unit continues to receive a ground signal, it senses that the vehicle is not closed and locked, and the system will not arm.

Usually, the dealer can use HDS (Honda Diagnostic System) to check the history data of the security system to see which sensor was actuated or not.
