Something may have gone wrong with the alarm so try cutting power to the alarm by pulling the fuse and see if things go back to normal.
Disarm the alarm before removing the battery.
Car alarm in Lexus ES300 started going off at random when car was parked, not running. I changed the key fob battery (flat watch battery) with a new battery and it fixed the problem.
You first need to check the battery of your alarm system. Your alarm system may also be going bad and need to be replaced.
The most common cause is that the rechargeable battery in the alarm siren is failing, giving a low voltage to the alarm system. When the voltage from he battery drops below a certain level the alarm system thinks someone is trying to disable the alarm by disconnecting the battery. As it thinks someone is trying to disable the alarm, it sets the alarm off.
Yes, that would definitely drain the battery.
If battery is low alarm auto activates.
disconnect the battery
There are a couple steps you can take when your 2002 Taurus alarm keeps going off. You can either disconnect the battery or bring your car to a professional to reset the computer in the car.
i assume you mean your marker lights. it sounds like your alarm going off, you must have a aftermarket alarm
Unplug your battery, then plug it back on
I put in a new battery and I was unable to start the car; I am wondering if this is due to the fact that I disconnected the alarm some time ago. This is the first time I've taken the battery out since I disconnected the alarm.
check your fuses
