Hi, I have a 2008 rx350 with both keys not being able to open doors remotely. I replaced the battery with a new one but still no luck. Where is the receiver for this function in the car and how can I troubleshoot it? I checked all fuses too.
thanks.

lexus dealer is suggesting buying a new key for $500 but I’m pretty sure that won’t fix the problem

 

Here yah go, wiring (to Body ECU) or module (Door control receiver) need checking:
