The red light next to my ebrake is blinking and everytime I open the door the alarms sounds. what is going on and how do I disable it?

 

I assume you have some optional/aftermarket alarm system installed and it has an issue. I doubt if any of us are going to be able to help you with this one.

 

the red led is a good bet of honda optional alarm, check the underside of the dash for a black push switch, a antenna sticking out from the driver side seat.

the thing is, you can still use the oem key fob(2) to lock/unlock door, but if you trigger the alarm on, and you use the oem key fob(aka non oem alarm fob) to open the door, it s gonna trigger the oem alarm

the oem keyless entry fob is the one without a metal right, the oem optional alarm fob has a metal right and a honda emblem.
