Can someone tell me how to disable the alarm on my Accord. I cannot always unlock the doors with the remote and when I unlock the doors with the key the alarm goes off and I cannot turn it off with the remote for several minutes. I have repalced the battery in both remotes. When I bought the car the rear drivers side door would not work with the auto locks, then one day it began to function normally. I would like to just cut wire and disable the alarm if I can open the door with the key without settig off the alarm life would be good.
