Car Alarms: Lincoln towncar alarm system, valet mode, lincoln towncar

Question
We just bought my father a used 92 Lincoln towncar.  The problem is the alarm system keeps going out on it and diabling the vehicle.  It has a sticker that says "Code Alarm" on the window.  We want to disable the alarm system.  Alarm companys will only do it if you purchase a new $300 system, and the dealership wants $80.00 just to look at it.  Thats too expensive right now.  Have any sugestions?  Thanks

Answer
You may be able to put the system into what is known as valet mode.  Valet mode will disable the security features of the system but allow the convenience features of the system to still function, like keyless entry.  If you do not know the model number of the system it would be difficult to know exactly how to put the system into valet mode but most systems operate in the same way.  Put the key into the ignition and turn it to the run position, and then press the valet button.  The valet button is typically mounted in the driver's area of the vehicle.  If you are not sure where the button is and can not find it I would suggest just removing the system.  Here is a generic how to on removing an aftermarket alarm:

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.
