By mistake I left the lights on for 24 hours, of my Infiniti QX4, the battery was discharged, I tried several times to help the battery with another battery, but when I connected the terminals (-+) an alarm was immediately activated and when I pass the switch ignition engine won't start...i didn't know the car had an alarm or immobilizer when i bought it.. Can someone help me?..i need to eliminate the problem and start the engine.

The alarm is reset by using the hard key to unlock the cylinder on the driver's door.

Just a friendly note.
