Chrysler Repair: Plymouth Breeze Wont Start, Cant open doors without alarm going off, car alarm system, remote keyless entry

Question
My wife has a 98 Breeze and she had a bad battery and today she went to get in her car the alarm went off and it wouldn't start. She doesn't have keyless entry or power locks it used to have a little remote with a panic button but we don't have it anymore. I thought the alarm got triggered because the battery was almost compleatly dead but when i put a new battery in. We were still unable to even open a door without the alarm going off. Got any suggestions please get back to me asap.

Thanks
Tony

Hi Tony,
About the only other idea I have would be to check fuse #4 in the power distribution center that is under the hood near the battery (20 amp). It supplies the power to fuse 5 under the dash. You could also go back to fuse 5 with a voltmeter or a 12V neon glow light and verify that you are indeed getting voltage on both clips of fuse #5. The only way to disarm the system other than with the remote keyless entry is to lock/unlock either front door using the door key. Because of the design of the door lock switch (it has a resistor built in that cuts the voltage to some unique specific value) there is no way to get around using the key in the lock approach to disarming. But for it to work 12v has to get to the switch from fuse #5. It is possible that the wires from the fuse to the lock switches that carry that voltage have "opened" at the hinge due to repetitive flexing.
So those are my thoughts on what you could do.
I hope that one of these will prove to work for you. Please let me know how you work it out so I can learn too.

Hi Tony,
The theft system armed state may have been caused by the battery replacement which to the car alarm system may look like an attempt to hotwire the car to steal it. Normally the disarming of the system should be accomplished by using the door key to lock, then unlock either the passenger door or the driver door. If you have tried that key approach at both the doors with no avail then I would check the 10 amp fuse in position number 5 in the fuse box under the dash as this is the fuse that is needed to power the door lock switch circuit that tells the alarm system that the doors have been locked/unlocked.
If that fuse were blown then the door switches would not be powered so they couldn't tell the alarm system to disarm.
So give those ideas a try and let me know what happens.
