How to turn off auto unlock when put in park with engine running

[Greg Woodart]

My 2021 XLT max is NOT set to auto unlock in the settings (auto lock only is checked) However every time I put it in park with the engine running ALL doors unlock. I've gone through all the Lock settings and cannot figure how to stop this. Any thoughts?

Perhaps go into the settings menu, and turn-on the Auto Unlock.

Shift into gear, then placed the vehicle in the part position.

Then cycle the ignition by turning it off, then restart the engine.

Go into the settings manual again and turn-off the Auto Unlock feature.

Shift into get then placed it in park again.

Sometimes checking-unchecking a selection will reset it to the correct operation you desire.

Thanks for the response. I tried it but it still is the same. I am able to turn the autolock setting on and off to control it as it should do...but the auto-unlock still unlocks every door the second I put it in Park with the engine running.

Do you have an auto start/stop eliminator hooked up to your OBD2 port?

 

[Greg Woodart]

Yes. Do you think it could cause door unlock problems?

heh. Congrats. You too have found an "hidden feature." They told me it's not supposed to happen, and the way to disable it is hold down the lock button until the locks lock/unlock/lock/unlock. I have to do this about once a month or so.
