Electric door locks?

My 2003 Durango has done this a few times. It always went away and it seldom happens. I cant remember if it was winter or not as we get -50 somtimes in norther Alberta. If it's only a one time thing I woulnt worry about it yet as mine hasnt done it again in over a year.

Mine was doing he same thing. Really cold here, and when iI had it in the shop for something else, the park lights started flashing, then the locks started chattering. Was intermittent for a few dys but stopped now. Mech thought ctm (timer control module) by left kickplate, maybe cold outside to warm inside, or beginning to fail. Still don't trust it to leave my keys in it.
