2007 Yaris Lock Problem

[clint2880]

Hi everyone, we're having trouble with our yaris at the mo where the remote keys won't lock or unlock the car. Furthermore, using the key in the drivers door only unlocks the drivers door - the rest remain locked.

Tried new batteries in the remotes with no luck. All fuses associated with the locking system are ok and all the harnesses appear to be fine.

I'm unable to locate the wireless receiver module or the relay that controls the locking system, so these are the only things I've not tried. Any thoughts?

May have to take it to either an auto electrician or a dealer for this one. If I use the key in the door all locks open, so there is an electrical fault on that circuit - I think
