I have a Chrysler Pacifica 2004, each time I open the door, it alarms so loud but stops ones I start the car. The noise freaks me out. How do I stop this alarm? I don't have the remote key.

Remove the postive cable from the battery (makeing sure that all gps ect have been unpluged) touch it to the negtive for 20 sec leaveing the neg hooked to the battery draining all power from the computer, them hook it back up. If this doesnt reset it find a loksmith shop that deals in transponder keys to help or at least point you to a shop that can help..
Hope it wors out for you!

My dad has a PT Cruiser that does the same thing when you use the valet key instead of the main key. You might have to go to a Chrysler dealer to get a key that will allow you open the door without sounding the alarm. Hope this helps!

Your key fob needs reprogramming, and yes the alarm will go off when you open the door, but you have enough time to put the key in the ignition which will prevent the alarm sounding. Car is usable until you get the fob sorted by locking and unlocking using the key.

The Alarm on my Mercedes ML320 sounded every night, then it started doing it more often, Showed it to the dealer he says it's the 'Tow Sensor', that needs to be repaced. $700, down the drain. I have already started hating this car, it eats $500-600, every 6 months...

Try unlocking the passager door

You need to first look under the drivers side dash area near the hood release/fuse panel area and see if there is a valet switch. The switch will look like a little toggle or a push switch. After you locate it, turn the ignition switch to the on position(dont start it) and flick the valet to the opposite position it is in now. If done correctly in most cases the red system light will stay a constant instead of off or blinking indicating you are in valet mode. Next try to start the engine. If this doesnt work you need to remove the alarm system and repair the ignition switch wiring or replace the electrical portion of the ignition switch. The aftermarket alarm cuts into the ignition switch wires and bypasses the start circuit through the alarm module. When disarmed the alarm completes the circuit and allows the car to start. Good luck hope this helps and please rate this.

you can try switching the key to the "on" position then open the hood and disconnect the negative terminal of the battery and reconnect after 2minutes. this will allow the alarm to be '"reset" and will recognize that you have the key for the vehicle.
