Question about 1998 Honda Accord
My car alarm went off and as I don't have a remote for it, I was unsure of how to dis-arm my car. I ended up driving while the alarm was still going off before finally realizing that I needed to lock/unlock the car with the key. Now, however, my horn doesn't sound at all. Help is appreciated!
Test for power and ground going to the horn. If it's getting power and ground, the horn is bad from running for so long

sounds like the drivers side key switch has failed remove the interior door panel and there will be a switch attached to the back of the key lock cylinder or around there it should be two or three wires also check the door jamb wire harness where the door closes for any broken or damaged wires, use a vot meter and see if you get power or ground to the opposite side of the switch when you use the key to lock and unlock the door if nothing changes and there is power or ground! at this switch i would replace it, i don't think there is one but if the car has a passenger side key hole try to unlock the car from that side and see if you get the same problem -jeff

For the system to arm, the ignition switch must be off and the key removed. Then, the multiplex control unit must receive signals that the doors, hood, and trunk lid are closed and locked. When everything is closed and locked, none of the control unit inputs are grounded.
The door switches, hood switch, trunk lid switch, door lock knob switches, and door lock cylinder switches are all open. Ten seconds after the doors are locked with the key or the lock knob, or immediately after locking the doors with the remote transmitter, the system arms.
If anything is opened or improperly unlocked after the system is armed, the control unit gets a ground signal from that switch, and the system is set off.
If one of the switches is misadjusted or there is a short in the system, the system will not arm. As long as the control unit continues to get a ground signal, it thinks the vehicle is not closed and locked and will not arm.
An alarm that sounds for no apparent reason may have been set off by a switch that is on the threshold of misadjustment. In this case, it may only take a significant change in outside temperature, the vibration of a passing truck, or someone bumping into the vehicle to make the alarm sound.

I had this same problem just today.Hhowever, I had the remote in my hand and it would not stop the honking!. Since I could get into the car, I released the hood, opened the master fuse box on the left side, and pulled the fuse labeled "Horn Relay".(On the upper left, there are three large, black, square fuses, it is the third and is labeled in the lid). I waited ten seconds and put the fuse back in, no more alarm, no more infernal honking.

Hi I wonder if you can advise me ,my central locking and alarm is very unreliable it keeps making a beep before the ignition goes on and clicking,it sometimes sets the alarm off,Ive had the AA round and theyve told me the car battery is dead,which I appreciate,but think the key hub central locking or alarm is running the battery low does the hand held button need a new battery,or can I take the fuse out for the central locking,dont want to pay 66 quid for a new battery if I can pay 2 quid for a new battery for the central locking button,or demobilize it
