Alarm Problem 2000 Ws6 with a factory alarm problem. What i am going to list are all symptoms related to the issue. The car currently has the factory alarm and an aftermarket VIPER alarm. I took the car to the viper dealer and assured me the viper alarm isn't the problem.
When getting out of car, i close the door and the factory alarm ENABLES on its own. When i open the driver side door after about 5 seconds the alarm starts going off.
While driving or parked, the locks go off randomly and the UNLOCK function wont UNLOCK the doors, only the LOCK function works.
Key fob doesnt work and the car wont go into programming mode, thus i cant program a new fob to disable or enable alarm. I can only disable the factory alarm when i insert the key and turn to the on position.
I've done searches and nobody seems to have my symptoms, please help guys..

An easy way to tell if the Viper alarm is messing with the system is to have whoever installed your system disconnect it for a week or two and see what the car does then.
WHat happens when you try to go into programming mode? Do your door chimes work?

It could be a poor installation of viper unit, but start small.
What you described sounds a lot like what a lot of fbodies do when the shock sensor that's usually hanging in a loom of wire by the spare tire area. This sensor gets moisture built in it and it does odd things like you mentioned.
Try unplugging it and see if your problem gets solved.

No, they can't, the alarm system is hard wired in the BCM. You can program the alarm system to be off (never activate) but you can't remove it. And programming it off can be done in your driveway - there's no need to go to the dealer. Instructions are in your owner's manual and posted here: https://ls1tech.com/forums/stereo-el...ml#post2965615

Okay, first of all, VATS cannot be "tuned out". The BCM (which contains the VATS circuit) is not programmable. You can bypass VATS by physically wiring the appropriate resistor into the sensor wires and you can program the PCM to ignore the missing fuel enable signal from the BCM when VATS is active but you can't program out the rest of the VATS tricks like disabling the starter relay. So, unless you've installed a resistor, it's likely that VATS is what's causing your alarm to trigger.
That's also what is likely preventing you from getting into program mode. You don't need a key fob to program the alarm off as detailed above but you do need to have the BCM recognize that a valid key is in the ignition or it won't respond.

so I'll just hard wire a resistor(code 8 which is 2370 ohm if my research is right) in and then that should allow it to recognize the key and then I should be able to get into program mode. Well I'll give it a shot. Thanks you.

Or you could buy a replacement ignition key with that resistor. Hopefully the solution is that easy. Please post back your results.

its been quite a while now and my problems persist, my symptoms are something that cant be found in a search, its frustrating. the car wont go into programming mode whatsoever and the alarm self enables every time the doors close. the viper alarm enables but does NOT lock the doors but does unlock the doors. The switch on the doors only UNLOCKS but does NOT lock the doors. my OEM fob is falling apart and is weak for signal now. i wonder if the viper is interfering with the OEM alarm, should i just remove the viper alarm completely and work around the OEM alarm?

While it is possible for the Viper alarm to interfere with the factory alarm, your symptoms don't point to that being the problem. The issues with the door locks in addition to the alarm would seem to point to the BCM being faulty. When Viper alarms are installed, they generally aren't wired to lock/unlock the doors directly but rather use a trigger signal to simulate the inside lock switches telling the BCM to work the locks. And assuming that VATS isn't the problem (SECURITY light on or flashing) then the fact that you can't get into programming mode also points to the BCM. Replacing your BCM may be your only alternative at this point.
