The remote should work too. If it does, and the doors don't, look for broken wires between the door hinges, or the switches are broken or disconnected.

thanks

Actually, if you're driving the van, it isn't in theft mode. The only thing the dash lights and running lights have in common is the Body Computer. That computer adds a lot of complexity and unreliiability to otherwise simple circuits. Unfortunately there is no easy way to test it other than to replace it. It sits up high against the firewall, inside the passenger compartment, ahead of the brake pedal. It unplugs when you pull it down, that's why troubleshooting is next to impossible.

Idk if this helps but when I turn the headlights on the lights stop flashin. Thanks

The dealership mechanics, and some independent shops with hand-held computers that can access the Body Computer can use it to activate various functions and to read the state of the sensors and switches feeding the computer That will give some clues as to whether the computer is acting up or if it is responding to something.

How can I disconnect the anti-theft device on my car?It has failed somehow and won't let me start the engine. thank you.

You cannot bypass the alarm on this car. Let try to reset the system by following this guide.

Electrical problem

----------------------------------------------------------------
I have a 1998 dodge grand caravan and the battery ran down and when I attempted to jump start it the intrusion alarm went off and the car would not start . I put another battery i that was already charged and when I connected the new battery the alarm went off and the car would not start.

Alarm and no start. Try unlocking the tailgate with the key, if that doesn't work, try same with passengers door.

my factory alarm system keeps shutting down and takes along time to reset not letting my van to start

I hate to say it, but a dealer is the only place that will have the proper test equipment to check it.

I just need to know how to disengage the alarm on my 1998 Dodge Caravan??

If it is a factory alarm, you need to have a dealer do the work.

I have a 1998 Dodge Caravan. Recently bought it off a guy who cut the factory alarm to shut it off. Now, the van back hazard lights always blink unless the headlights are on. And, after about 2-3 miles the van completely shuts down and has to be jump started. Help!

You can't "cut" the factory anti-theft system. When it is activated, the engine will run for only two seconds, then stall. It sounds like you have a charging system problem. Jump-starting is the clue. That won't overcome any anti-theft system. If you charge the battery at a slow rate for over an hour, you'll find the van runs a lot longer.

Start by using an inexpensive digital voltmeter to measure the battery voltage while the engine is running. It must be between 13.75 and 14.75 volts. If it is low, measure the two voltages on the two small nuts or the two small wires plugged into the back of the alternator. Those must be measured with the engine running. Holler back with those numbers.

Can i have my key pad re programmed at a car alarm shop or the dealer or jusf get another key pad alarm?

dealer for re programming but if you normally buy anew one there they reprogramm all of them at asame time
