If you set the alarm (i.e. lock the car) and then disconnect the battery, the alarm will go off. If you disconnect the battery when the alarm is not set (i.e. when the car is unlocked) the alarm will not go off. (So don't try to nick a locked one).
If the battery is dead the alarm will not go off
yes
I have a Honda Civic and the battery died, so i hade to jumpstart it and the alarm went off. The alarm went off because the security system that protects against robbers ext. But in my case, I had to put a master key into the ignition to stop the alarm.
Yes, that would definitely drain the battery.
If it's a factory installed alarm, you should be able to turn it off by: Disconnecting the battery. Next close all the doors on the car. With the doors closed, reconnect the battery. Go to the passenger door and use the key to first lock, and then unlock it. That's how I've gotten them to turn off in the past. If that doesn't work, disconnect the battery, put the key in the ignition and turn it to the "ON" position, and then reconnect the battery. Then close the doors, and then lock and unlock them from the passenger side with the key.
The alarm of a 2004 Honda Accord will go off when the battery is disconnected because it is part of the anti-theft systems programing. When the battery is reconnected the alarm automatically arms itself.
Affirmative. You must find out which fuse controls the alarm and remove it prior to reinstalling or re-connecting the battery. Have your remote handy when replacing the fuse as the alarm will go off!
To disable the alarm on a 2011 Honda, you can use the key fob to unlock the doors, which typically deactivates the alarm system. If the alarm is still sounding, you can insert the key into the driver's door lock and turn it to the unlock position. If the alarm continues to go off, disconnecting the car battery for a few minutes can reset the system. Always consult your vehicle’s owner manual for specific instructions.
if you did disconnect the alarm, it wouldn't let you start the car because of the immboliser
Mine did that for a while, I tried everything, except replacing the battery. When the battery gets low it triggers the alarm. It turned out to be an easy fix
Try disconnecting the battery for at least 10 minutes and then reconnect and try. Check the starter, it don't all the time go right out it will crank but not turn the engine over when it start to go bad, then you you will hear the clicking latter on.
