My 2015 Honda Accord 9th Gen sometimes will sound the horn alarm for no apparent reason, usually just after I approach or leave the car.

I recently got both my key fobs replaced with an aftermarket key fob, cut and reprogrammed by a locksmith. They key and its buttons work great. But it is really annoying to scramble to shut off the horn alarm as my wife and I are defeaned about twice a week for no apparent reason. She's ready to sell the car because of it.

At first I thought it was due to accidentally pressing the PANIC button in my pocket, but several times it has happened when I am certain I did not press it.

1.How can I totally disable the horn alarm and panic feature? It is nothing but a hassle and I cannot imagine it ever helping me, since everyone ignores it anyway. I hate it.
2. Any ideas to fix the problem more directly? Could it be something with the key fob?
