 i did first one i mean lock all doors but i am trying to unlock them with the ignition off . dosnt work

 thanx

first off, try to explain yourself better

are you installing anything on the car?

what are you installing?

if your not installing anything, and trying to make the ignition lock(when turning on) and unlock(when turning off) your doors, you might want to check your manual, it might tell you how to program that feature.
