Truck lock.
 

I had a car prowling on my 2014 Ram two nights ago and it appears that it was my fault as I found the truck unlocked.
My frustration is that I usually lock my vehicle by pushing the button on the door handle and on hearing the horn beep I think I am good to go. On a few occasions over my ownership I've noticed that sometimes it does not lock and I must push the button a second or third time. If I use my Fob it locks every time.
Has anybody had this problem?[dummy]

That's funny you asked.

I noticed last night the front passenger door lock is moving slower then the other locks when using the button on the door. I had to get something from the passenger side so I used that door button to avoid tootin' the horn with the FOBIK. I locked and unlocked it a few times and the lock became less responsive with each press, to the point the lock didn't go all the way down.

I tried it with the fobik tonight after I noticed your post and locked/unlocked it and it seemed to work fine with each press, unlike using the button on the door.
