Hey guys, searched around but couldn't find exactly what I was looking for. Alarm would go off randomly so upgraded the unit to a new Viper 3400(3100 module.) Alarm is still going off randomly with the sensitivity turned all the way down (confirmed no reasonable cause for trigger.) Battery is new, terminals are upgraded. I read that It is likely a bad sensor in either door, hood or trunk latch. I want to replace all 4, cant have my neighbors getting pissed at 3am again, the viper siren is LOUD.

Does anyone know what part numbers I should be replacing?

Is this what I need for the doors? LC11-66-540

Any other comments or suggestions to solve this issue would be greatly appreciated. I need a fully functioning alarm.

Thank you in advance!

 

Check for the neighbor's cat or other critter jumping on the car?

 

I had issues with the rear hatch lock sensor. I thing changes in pressure cause the hatch to lift slightly and the sensor contacts might have issues. I unplugged it and the problem went away. Obviously not the proper solution but one that works until I decide to dive into it.

 

I've got an FC but I suppose that the alarms are similar. I once had a similar problem. Alarm would trigger randomly as yours is doing. The microswitches in the door handles are, for lack of a better term, slip fit. On my driver's side door handle, the switch slightly slipped out position causing the alarm to sometimes trigger. Not saying this is your problem but it might be worth checking out during the trouble shooting process.
