no it doesn't if the door is opened when its ON it makes a circuit and starts the car alarm
you just have to put an alarm for a couple days then you will get used to it and dont have to have an alarm :J
take them out . you should charge battery then be ok.
Bad battery or drain in the electrical system
Yes, if your car sits a few days at a time and your cars interior lights periodically come on it will drain your battery.
The BT50 lasts about four hours under use, and can stand by for a couple days.
Just reset the radio and that is all.
It just happened to me a couple days ago..I found that my alternator belt broke and had to be replaced.
check out your alternator
Battery out. Leave it to dry for a couple of days. Try a different battery; sim card; charging; not charging (try all combinations). Take it to a repair shop.
Leave the car where there are a bunch of cars stolen at, and leave the keys in it and the doors unlocked, then wait a couple of days and it should be gone.
something is draining the battery. a new battery will last a couple days if just starting the car. even if your alternator is bad.
Bad battery - won't take a charge? Defective alternator not charging battery Check with a voltmeter Without engine running reading should be Approx. 12.8 With engine running (alternator charging) reading should be 13.8 - 14.2 volts
