Turne inition on alarm goin on - Eclipse Mitsubishi Cars & Trucks

Go to your passenger door and use your key on that door to unlock it. If its like a Nissan Quest I once had this should solve your problem.

When starting my truck it sometimes make a humming sound.

Contact AVITAL company. This sounds like the alarm is killing the ignition or fuelpump circuit. Sometimes there is a sequence used in alarm resets and you should know it if you are out in the Boonies without a Cell signal.

When yo disconnected the battery, it set the alarm. If you have a remote control key fob, go ahead and connect the battery. Using the key fob, turn the alarm on then off. If that doesn't work, use the ignition key in the drivers door lock, turn the key all the way to the left, then all the way to the right. This should shut the alarm off. If it still won't go off, look for a reset button under the driver side dash. Hold the button down until the alarm beeps once. If you can't find a reset button, and nothing you've tried will turn the alarm off, you will need to seek help from a dealership, or a shop that specializes in alarms.

Try locking and unlocking the drivers door using the key. Usually that will re-set the security system. Also try the rear hatch lock as sometimes that is used instead of driver door.

1. check batt voltage
2. check all fuse
3. check starter wiring and voltage to starter.
4. disable alarm(disconnect immobiliser) and then try and start

Try disconnecting the battery and putting the key in the ignition and turning it to the "ON" position. Reconnect the battery and the alarm should be deactivated. I'm assuming you don't have the alarm fob? This might be a good time to remove the alarm system.

its probably the key alarm the lock cylinder may need to be replaced

sounds like you may have a faulty ground wire to your alarm system short of un hooking the battery i would suggest going to a garage and have it inspected

There should be a key switch under the hood but you need a different key to the ignition key, it is usually a much smaller key than the ignition one.
