Can you set off your alarm by leaving a window down and locking the car, then a min later unlocking the car from the inside and opening the door?
Wacky. I just locked with door open, with door closed both with FOB and then reaching through open window to unlock and open door. Did not set off the alarm either time. On my 96, if you lock the car with the FOB and then reach in an open window to unlock with the power lock it WILL set off the car alarm.
Maybe it has to do with Passkey-3 ? Maybe the chip is the determinant? Does the car search for the passkey signal nearby? I don't know enough about how passkey 3 works to answer.
