Key fob works windows and entry lights as well as rear hatch; however, will not lock or unlock doors. Central lock button in vehicle does not work either.

Fuse 20 (30 amp), passenger compartment fuse panel. See owners manual.

Remove and it will make all power locks and hatch inoperable (electrically) and you will be required to manually lock/unlock all doors and use a key to unlock the drivers door to gain entry into a locked vehicle. The hatch will not operate as it is not mechanical release as are the doors.

If you want only to disable the key pad, you will need to disconnect the pad from the smart junction box... not a task for the average owner. It may also cause a CEL/MIL indication.

If you want to test removing fuse 20, roll down the windows prior so you have access if key entry somehow fails.

You could wire a switch (30 Amp) into the fuse 20 circuit and have a selectable on/off so you have hatch release or all functions when wanted.
