Hello everyone, I have an issue with my driver door keyless entry on my '21 lariat . It started working intermittently for a while but not it doesn't work at all anymore. Passenger side works perfectly. I changed my fob battery and try to disconnect the truck battery for 10 min, no change. I scanned the truck with ForScan and no trouble codes shows. Is the touch sensor dead?

I would take the door panel off and check the connectors and wiring to the door handle. Below is the wiring diagram for the door handle circuit.

I'm not sure about Ranger, but if the Battery State of Charge (SOC %) is below 40%; the Passive Entry System may be disabled. I'm sure you can check it with ForScan
