When I push the lock and unlock button on remote together, TPMS will not go to relearn procedure. none of the buttons work on either remotes(batteries are new in both), I havae had Tech2 scanner hooked upto manually relearn TPMS t will not go into relearn. Drivers door does lock and unlock all the doors with the button on the door itself. Someone tyold me there was a door lock transmitter in the right rear back window deck???? Is this correct? Is there any interchangeable years to replace with a used one if it is in rear window?
