2005 Kia Sedona. Battery Died, now when trying to jumpstart the alarm starts going off when cables are connected and jumper car is turned on. Could this be a security feature of the factory installed alarm system. is there a simple alarm reset that I can try before I spend hundreds to get it towed to dealership and fixed?

Push the lock button on your key fob for three seconds, until the lights on your dashboard blink. Your key has been reprogrammed, and your alarm and computer have been reset. Turn your Kia off, remove the jumper wires and close the hood.

Stick the key in the Driver door lock and turn it 3 times to Lock and Unlock the door, the alarm should reset.

On most vehicles, you insert the ignition key into the ignition switch and turn the key to the run position. Then start the car.

Try disconnecting the neg. battery terminal. Open the drivers door and leave it unlocked then reconnect the battery back up.

Most likely you've got something draining the battery. Read this post

You can probably pull the horn relay to kill the horn while you are working on the problem.
With the battery connected to a jumper, try locking and unlocking the driver's door with the key. If that works, make sure the battery gets charged before you unhook the jumper cables to keep the computer memory alive.

It sounds like your alternator is bad. Here is how to find out:

Start your car (jump it if necessary)

Let it run - while it is still running - disconnect the battery cables from the battery.

If your car suddenly dies, most likely its the alternator.

If your car does not die after disconnecting the battery cables - then its probably a bad battery and your alternator is working fine.

Hi,
You will have to have a charged battery firstly. If you have a key over-ride on the alarm siran housing turn it OFF. If you have jumper cables connect them to your vehicle (observing polarity) Negative jumper cable should be connected lastly ! When connected , operated the alarm blip as normal and you should be able to silence the alarm and start vehicle as normal. If the battery is in a weak condition it will drop a lot of voltage(while cranking) and reset the default setting on the alarm (ie ON) So good connections and good battery voltage. If it does go off , it'll be only for a few moments and it's your vehicle anyway so ! Good Luck

The Magnum's battery is located next to the spare tire in the trunk area, but there is a jumpstart post under the hood also. On the passenger side of the engine compartment in the front, you'll find a red cap with a plus sign on it right next to the fusebox. Lift this cap and you'll find the positive connection for the jumper cable. Behind the fusebox there is a good negative connection point, but usually any uncoated solid metal, like a bolt head, can be used for the negative connection.

Try jumpstarting it. My 06 has done that a few times and jumpstarting has worked every time. Usually, one of the kids left a dome light on or something.
