Car will trigger itself to start to accessory mode, turning on lights, wipers, and sometimes triggering the alarm system when locked and armed. All scenarios tried below, vehicle will respond the same.

Honda Dealer unable to diagnose the issue. No solution found, problem remains. Diagnostics is convinced the issue is due to having both keyless fobs in the vehicle, but issue began 3 weeks and continued consistently prior to carrying the second key for backup assurance.

Variations tried to eliminate trigger, no differences occur - car SELF TRIGGERS TO ACCESSORY MODE.
--- 1 key in vehicle
--- 2 keys in vehicle
--- Both keys in vehicle, one with battery removed
--- Both keys in vehicle, both batteries removed
--- NO KEYS in vehicle (close proximity)
--- NO KEYS in vehicle (over 50 feet from vehicle)

Under all circumstance, vehicle responds the same, triggering on the electronic system of the vehicle without pressing the push to start. Forced to disconnect battery so vehicle does not die or trigger to sound the alarm system everyday or night while not supervising activity.

Any insight? Comments? Suggestions?

Possible root causes, but not suspected by Honda dealer master tech.
Ignition switch
Fuses
Keyless entry fobs
Wiring/connections

At my ends here, dealer had the vehicle for over 3 hours, no solution found.
