You need to find the black push button called the valet button. That is the overide. Get in the car turn the key to IGN as the alarm is going off and then you have either 5 or 10 seconds to push that button once and then 2-5 seconds later the alarm is shut off. To put the car into valet mode which means no alarm at all you put the key to IGN push that button once then pull key out at which point the blue light should turn solid blue.

Or option two is you open a door and hit the lock, then unlock, then lock button again on the remote and the blue led will be solid which means no crazy alarm.
