Hello Folks, I have a master key in working condition for my 06 Rx400h but I lost a valet key. I have cut a valet key from the dealer & surprised by the hefty charge just for programming the valet. The valet key lights the panel, air conditioner and radio etc fine but it wont start the engine. I see the security light blinking once every sec so it tells me that immobilizer needs to be programmed to accept this key. I have read and exercised some posts about reprogramming with a valid master key. But none have worked. Just wondering if anyone has programmed valet successfully on this vehicle and any help / standard steps how to proceed? Thanks in advance
