Ok, I know this is very weird....but it drives me nuts. I hate how my alarm arms when I get gas. (1)While I'm sitting in the car, I have to disarm it before I start the car again. OR (2) Sometimes I get out to clean the windows and stuff, and then I might get locked out. I guess I could open the door a little or something, but I'd rather install a SWITCH Preventing alarm while getting gas -- posted image. .

So, can I install an ON/OFF switch that will give the alarm a signal that will mimic the door being open? (So I guess that would be a ground signal). I guess this is sortof like being in valet mode without really being in valet mode.

what kind of alarm is it? it's on passive arming, it should be as simple as reprogramming the alarm.

You have the auto arm feature engaged. This feature auto arms the system after the ignition is turned off. Is this the Viper 550 ESP system ?

yes (that's the alarm), but i would like to keep the auto-arm feature if i ever get out of the car, and forget to arm it Preventing alarm while getting gas -- posted image.

This would just be a temporary disable so the alarm wouldn't "auto-arm" in certain instances where I don't want it to do that....I just want to trick it.

Leave the ignition on while you sit in the car while getting gas. This way the system won't passive arm itself.

True. But if I wanted to take the long way around, and use a switch Preventing alarm while getting gas -- posted image.

, could I just put a switch inline with the alarm's door wire? Then, if the door is shut, and I flick the switch, the alarm will get a (---) signal, and think the door is open.....and not arn. Or will that not necessarily give a (---) signal if the switch is flicked....but rather just neutral? (and no, i don't use forced passive arming which will arm even though a door is open).

ok cpgoose - here is what i did - i had the same problem

usually an alarm comes with + and - door trigger. if your car is - trigger then you obviously will not use the + wire ( i think this wire is purple)

Take the purple wire and hook in up to the ignition so that when the key is out the ignition ,the purple wire will see a + signal . it would be just as opening a door . when the key is in the ignition then the wire will see no signal and think that the door is closed. this method uses the ignition and key as a switch but uses the + door trigger.

Alternatively you can hook up the same purple wire to a switch and 12v for the same results.

This will depend on the vehicle, but sometimes if you leave the interior lights on, the alarm will think the door is opened and therefore will not passive arm. I would try this before doing any rewiring/reprogramming.

I just leave my door open, but it would be as simple as making a switch inline that creates the illusion of the door being open (i.e. if you have negative pins, just a switch that grounds the door lead). I would just be careful of this because it would be easy to forget about the switch. You might want to get a dpdt switch and hook one side to 12v+ and use a little led somewhere in the dash to let you know that you have the door bypassed. Also, on most alarms, if you were to forget this and arm the alarm, that zone would be sensed as faulty and not be armed, which means anyone could open the door without triggering the alarm. If you think you can remember to turn it off, or wire in an indicator led, I think you shouldn't have any problems.

cpgoose, to avoid the door trigger issue, you could use a toggle switch to trigger a relay to open the alarm's igniton lead and supply 12V+ to the alarm side of the lead. When you go to arm it and if you had forgotten about the switch, the alarm will not arm. You could also incorporate an LED with this as NyxBass suggested.

30 to alarm's ignition lead

87a to ignition

85 & 87 to constant 12V+

86 to ground from switch
