Okay guys, today's problem has to do with the electric locks. I went out today with the set of keys without the remote fob. I had no problem locking or unlocking the driver's door but the key would not lock or unlock the passenger doors or the tailgate.
All work correctly with the remote and if the lock/unlock button on the armrest is used.
I double checked with the other key and it acts, or more precisely, doesn't act in the same way.
Settings: Auto-Lock at 15 mph Auto Unlock at exit All doors lock/unlock together
