SOURCE: security system/battery

plz check the following and update me
1. Fuel (To be exact proper air/fuel ratio, normally it is about 14/1)
2. Spark (in appropriate moment)
3. Proper timing (the valves should open and close only in appropriate time)
4. Compression in the cylinders (Normal compression is 120 - 170 psi. The engine won't start if the compression is lower than 70 - 80 psi.)

if you don't have the remote, just use your key. put it into the door lock and simply turn the key, that will shut off the alarm.

SOURCE: my battery is dead and

Try disconnecting the battery for 5 minutes. then when you reconnect the battery lock and unlock the drivers door with the key, door closed. this will on some models deactivate the anti theft system. but it must be done with the hood closed and all the doors closed and from outside with the key. mike

SOURCE: changed out dead battery and horn wont stop

Changing out the old battery, you may somehow shorted something out in the car. You can check this by seeing if you have any power going to the lights on the car and what ever else that uses the power when you turn on the key. Newer cars like yours usually cant short out, but if the lights and other stuff dont work when your check them, disconnect the battery and look for the fuse panel. Check ALL your fuses and make sure none of them have been blown. You can check that by seeing if the filament in them looks to be burnt or broken as if it popped.
You can also check and make sure that the negative battery terminal is on tight enough. Sometimes a bad ground can mess everything up. As your doing this, before your reconnect your battery, go under the hood of your car and disconnect the horn. This will allow you to work without the horn blaring. To disconnect the horn, its just a wire with an end that simply slides over a metal tab, just give it a pull and it should come right off. You may have two horns so check both sides of the radiator. Hope this helps!

2006 Chevy Cobalt power dying with new battery in it, is it the starter?

If the car died while you where driving it, it sounds like it is the alternator. Did it start right up or did you have to boost it? If you had to boost it to start it again,I would say it is the alt., but if it started right away w/o a boost, it is something else.

92 Toyota 4runner truck was running perfectly fine Later in the day went to start and the alarm just started going off and wouldn't turn off. Truck won't start even with keys turned in igniti

The alarm system somehow got activated , this is usually because the battery becomes discharged or disconnected try doing this:
Remove the key from the ignition
disconnect the negative battery terminal
put the key back in and turn to ON
exit the truck and leave door open
reconnect the battery terminal
get in and leave door open, if the alarm horn stays off it should start.

Truck won't start but the horn honks when I turn the key.

Sound like a wire loose. could be the earth cable to the engine, or the main power cable from the battery to the fuse box/ignition switch/starter.

I tied to jump my 2010 honda odyssey. it ntook the charge, but the horn wouldnt stop even after i started to drive. I turned it off, and the horn still wouldnt stop. eventually the car died again.

this is an anti theft problem because your battery went below 10 volts.try charging battery up to proper levels and reconnecting to vehicle should be fine.

My 2001 Kia Sephia suddenly won't start.

even if your starter is out it would still click when you tried starting the car. so try replacing your battery first thats the most common problem for random starting. also look under the car you may need to jack it up. look under the intake manifold that is where the starter is check to see that everything is hooked correctly and that all the bolts are tightend securley and not loose on one side.

2006 corolla- check engine light comes on. i replaced the battery (old) and i reconnect it, it runs fine for about a minute, no warning lights, then shuts off, check engine light is lit and will crank but...

Open hood ensure new battery is disconnected.
Open main fuse panel cover under hood and remove horn relay (so you don't have to listen to the horn).
Use the key to lock the drivers door.
Connect the positive battery terminal.
Connect the negative battery terminal (security system will now activate, hazards lights will flash and horn would be going off if the relay was not removed).
Use the key to unlock the drivers door.
Get in, close drivers door.
Use the key to start the engine.
Security system will deactivate.
Get out of vehicle, reinstall horn relay, replace fuse panel cover, close hood.

2006 Mitsubishi Eclipse won't start in the winter...(15,000km)

Try using a fuel treatment. Sometimes water builds up in the lines and makes it hard for the car to start cuz you can't combust something thats frozen... I'd recommend Lucas Fuel Treatment... either that, or maybe new spark plugs, though if the dealer thought they were fine, I don't think that's the case.
