My 2016 GX 460 wont lock. It beeps really loud when I get out of the car and even when I’m sitting in the car, turned off, door open...no lights on etc. I’ve checked all the doors, the back gate & hatch and everything is secure. There are no warning lights etc. when I walk away with my key fob to lock it won’t. Also won’t from the app.

Is this a setting? A sensor etc? I’ve tried everything and never had this problem. Thank you!

Are all the power door locks working? You may want to look at each one to confirm they are actually fully locking/unlocking

I saw that behavior when my driver door power door lock was going out and it couldn't quite lock the door.

If another key was left in the vehicle it would do this as well.

If there's another key inside the car you can't lock it using the sensors but you can lock it using the key fob by pressing lock at least 2 times.
