Hello, the red flashing light you are seeing is the security system light. That is why it starts flashing with the doors locked. If you are having an issue with the A/C I would gladly advise you on that also. However I will say that your vehicle is most likely under the factory warranty still so you can get that checked and fixed free of charge at any Honda dealership. I hope this helps.
