it's baffling. i don't recall anyone having a one way problem before. i hesitate to say it's a bad circuit board, but maybe there are separate receivers or transmitters.
well i bought it used and he said it hasn't worked for a while. also i only have one fob. and all the research i have done is the same they don't have one way problems like this.
it's probably overkill, but mini vci and a service manual would probably do it. but maybe you should pull the door panels first and have a look around.
I have prius of 2011, i changed my navigation system, after that it has not locking or unlocking even from inside of the vehical! Not from the key too! Fuses are all good: can anyone help me?
Your car is a Gen 3 and you have posted in a Gen 2 forum. Maybe ask your question in one of the Gen 3 forums.
