So my girlfriend just got an sc300 and unlocked the door from the passenger side and the alarm went off. She goes to start the car and it won't start . I know these cars have the anti theft starter kill. Does anyone know how to fix this?

I would pull the battery and restart it and give it a shot see what happens leave it off for like ten mins it will restart the ecu and could fix ur problem

Car must be unlocked from driver side only to disable alarm....

Unlock the car from the passenger side door it will start up instantly after

drivers side works oo, too me like 20 mins to figure it out lol

Close all the doors, insert key into drivers side door, turn to unlock position and hold until alarm turns off. (I think)

^ this didn't work with mine...could my key be f***ed up?
