I have a US spec 1993 300E with factory alarm installed. (has worked well till now)



yesterday the alarm on my benz totally flipped out on me while driving(started sounding the horn,flashing lights) after pulling over and attempting to turn off the alarm using the key, i was surprised to find out that the alarm could not be disengaged via the key at either of the doors nor trunk. (the little red light on the dash is constantly blinking)



i plan on trying to fix it if possible.



Could someone please tell me does the factory alarm have any relays that could be causing the aforementioned problem? if so , where are they located?


any other suggestions ?


thanks in advance
