Car Alarms: False car alarm, hood latch, starter wire


Question
1999 Honda Accord.  Alarm goes off for no apparent reason.
The battery in the transmitter has never been changed but remotely operates the door locks fine.  ----heard that low battery can cause this but I can't see how unless there are built in troubleshooting events---- I am going to have the alarm permanently disconnected by the dealer.  Dealer had no solution, however, one tech suggested cleaning the hood latch since it is more frequent during wet weather.  Had this done but car kept me up all last night.  ---- I disconnected the battery!! and got a couple of hours.
Thanks.


Answer
The remote will not cause a false alarm.  The hood pin, or the impact sensor could definitely cause a false alarm.  Having a dealer remove the system could be pricey.  Here is a generic how to if you want to remove the system yourself...but I would try disconnecting both the hood pin and the impact sensor before removing it.

Typically an alarm system would be installed on the driver's side interior of the vehicle.  This system would have been tapped into the ignition switch wiring running down from the key.  If you remove the dash panel(s) under the steering column you should be able to locate where the harness was added that goes to the alarm.  Disconnect each wire that was tapped in and insulate the factory wiring.  You will also see that at least one of the wires was cut, this is the vehicle starter wire that runs from the key to the starter.  This wire needs to be restored, I always recommend soldering all connections but crimp connectors should also work.  Make sure that you remove all connections to the alarm and that any wires that may be exposed are insulated and mounted in a way that they will not interfere with any moving parts and do not run the risk of shorting out.  Remember to take your time and follow each connection running from the brain of the system, leaving one wire connected that you are unsure of the function could cause problems in the future so be sure to remove every wire.
