Since having my isf i have experienced a few self unlocking issues. This morning i woke up and found, for the 3rd time, my front windows fully down and the moonroof partially open. It also rained, like last time! My local lexus branch isnt open on a sunday, so anyone got any ideas? I assume i have been sat on the key in my pocket or something. As well as this problem iv also had the doors not locking after parking her up. I couldnt do. Anything with the key, including start it. Eventually i got a message on the. Dash telling me to place fob on start button to reprogram it. It worked but its just another problem.
