1995 Factory Alarm

I dont believe that any had "factory" alarms, just keyless entry, I know the cobras came with a alarm of some sort but it didnt atomatically engage, (mine didnt). Just go to a stereo shop and have it removed, or there should be a valet switch somewhere under the dash. Good luck.

I had a factory installed alarm/keyless entry on my '94, it had a valet switch/led light right above the headlight switch, you can see it in this pic, its the little red dot:

(old pic, those floormats have since been replaced)

Mine would arm itself 30 seconds after the ignition was turned off and as far as I know, there is nothing you can do about it but put it in valet mode, but I didn't have any luck with this on mine. IIRC you have to turn the ignition to "on", then press the red button on the dash for a few seconds till it starts to flash quickly. The car should be in valet mode and should not arm itself. I could be wrong though. This never seemed to do anything for me
So I finally got rid of the whole system, and put in a 2-way paging alarm w/ keyless entry. Its 187,304,565 times better than the factory system.

I had a Ford alarm installed on my car when I purchased it new. The Ford alarm is actually made by Code Alarm, although the alarm has a Ford sticker on it. BTW, you can purchase the code alarm replacement key fobs to work with the original Ford alarm.

Yes, you can deactivate the passive alarm mode. As mentioned, with key in, engine off and alarm deactivated, press the red light and it will flash twice in quick succession. This is valet mode and the active and passive modes are deactivated.

See we learn something new every day... I thought all the alarms were aftermarket, accept for the cobra's alarm.
