I wonder how old the alarm system is. Many of these systems failed eventually due to corrosion in the electronics. Before replacing the alarm unit make sure wiring is ok ( no cracked wires or loose ends). The alarm systems usually come with a manual that shows you how to reset it. Try to do that before decide to replace the unit.

1997 crown Victoria. viper alarm kill switch has turned all power to car. How do I reset

there is no override. Otherwise it would defeat the point of an immobilizer. I would find out why the alarm went off and deal with the rot cause rather than trying to bypass something made to be un-bypassable.

You may be able to reset the alarm by unplugging the battery from the car for a minute or 2 but I would start with the alarm manual to be safe. Possibly even remote the alarm and put the wiring back to stock.

The car alarm going off by itself. did it last summer and starting again.

Aftermarket alarm or a manufacturer equipped? If it's OE then more than likely there's a problem with the body control module, or a problem with one of the switches or wiring in a door/hood/trunk. Basically what's happening is one of the switches is making the car think a door (trunk or hood) opened and setting the alarm off. Or the module that controls that system is failing. Moisture, humidity or age can cause these problems. If it is one of these problems, sadly enough you're going to have to take it to a shop to have it diagnosed. Other possibility, a weak car battery (2008 would have a 6 year old battery in it if never been changed, even if that's not the culprit I would recommend a new one especially before winter.
maybe disconnecting battery for a while then hook it back up my reset the system.

My 1997 jeep grand Cherokee alarm system keep arming itself about a minute after car is turned off even if car is unlocked with windows down can someone help

Speaking from prior experience, It's possible that the door lock latch assembly may need replacing usually the drivers side or the lift gate latch assembly. These are the 2 that can arm & disarm the alarm system. You may have a faulty switch in either of these. Hope this helps.

I have a problem with my hazzard light coming on when it feels like on Audi 2003 a4 can't any tell me wat wrong ?

If your car has a switch in the dash like my 2000 A6 does then the first and most probable thing it can be is the switch itself. Another possibility is the "multi-function" switch which controls the turn signals, cruise control and head lights dimmer, it may be shorting internally and turning the hazard flashers on. If the car is equipped with a factory alarm system, it could be faulting and trying to arm itself while the car is in operation. If tapping the dash mounted switch turns the flashers off then the switch is most likely the culprit but if that doesn't help or changing the switch doesn't help then either replace the steering column mounted multi-function switch or have the factory alarm system disabled. Of course this hint only applies if the car's wiring harness is intact as it left the factory. If there has been custom wiring done for a stereo or non-factory alarm system then all bets are off and good luck!

The alarm system on my 2001 Volkswagen Jetta GL keeps turning on by itself

You must have the dealer keep the car until this fault occurs and then scan the security system to see what is causing the triggering of the security system. It is very possible that the drivers door ajar switch or latch switch is defective and it triggers a false tampering signal.

Alarm goes off in a locked car by itself

You may have a door,hatch or hood that isn't latching completely causing the issue or possibly a faulty door lock alarm switch.

Could either, could be alarm or ignition relay or ignition switch itself, could also be transmission selector switch try putting transmission lever in neutral and then start if it does the same you will know it one of the other causes. Have auto electrician check alarm and ignition relays.

Everytime I lock the car using the key fob, about 30 seconds later the alarm sounds but the lights do not flash and the horn does not sound. Only when I unlock the car will it go off. I have disconnected...

you may have a bad door switch, theres a switch on the drivers door lock, when door is unlocked with fob or key the switch is activeated to shut alarm down,the lock moves to hit switch with key or fob,so if the switch is bad it will not shut down alarm, i would start there,door panel has to be remove,then latch has to be remove to get to switch, then test with a meter see if it opens and closes the connection, hope this helps.
