Because the car alarm needs to be disarmed before you open the door. It's not connected to your door locks.
with the key... or a slim Jim Key is not working at the door
On a 1996 Camry. you just gotta turn your car off, than open the door then the alarm will sound, after you close the door, turn the car on (not the engine), and then turn the switch to off, it is located by the handle to open the roof. Then alarm should turn off.
Start the car with the trunk (hatchback) and driver's door open. The alarm will be deactivated. I don't know how to turn it back on.
If it is the Honda Pilot Factory Alarm, it goes off only when "the doors are open" or "the hood is open" while it is armed. If doors are not closing properly, or the door sensors are not operating properly (the car thinks the door is open), the alarm can go off. If all doors are fine, then turn to the hood switch that detects whether the hood is open or closed. If this switch is faulty, the car thinks the hood is open and the alarm goes off. You have these 6 things to check (5 doors and hood) and nothing else for the factory alarm.
why does my door ajar alarm keep coming on and off while driving my car.
You break into your own car and see if an alarm goes off. Remain in vehicle and try locking all doors with remote or electric door lock switch Then try unlocking door with manual release and open door - alarm should sound off
it is the door alarm
Do this by using your key in the driver's door lock. While alarm is tooting your horn, simply proceed as if you were unlocking/locking your door. Do this by using your key in the driver's door lock. While alarm is tooting your horn, simply proceed as if you were unlocking/locking your door.
I had a similar problem when I first got my Avenger. My remote was not working, so everytime I locked the door ( while open)the alarm would arm. This is the trick: Lock the door when it's closed, don't lock it when it's open otherwise the alarm will go off. OR You can disarm the alarm by unlocking the trunk with the key. I learned of this from a Dodge dealership. Had issues with the remote and once you lock the car from the inside or out it is armed. I ran into times where i would lock the door after getting in then once i started the car alarm would go off or once locked you cannot open the door from the inside or alarm will go off.
my hand set wont unlock my doors with new batteries and when i unlock the door with the key and open it the alarm sounds and wont let me start the car
When why open my Chrysler 300 door with key and the alarm goes off I immediately put key in the ignition and turn car on, the alarm quits instantly
