Independent Dependents - S1-E7

Plot hole: When Helen goes into the air ducts, she simply removes the grates. They would not be loose like that, they would be firmly attached. When the team enters the basement they go through an ordinary door by picking an ordinary lock. A very high security installation like Axe Industries would not have such an insecure entry, even into the basement.

Butterfly in Shades of Grey - S12-E2

Plot hole: Columbo says that all the doors and windows at the murder scene were found to be locked. But Fielding Chase left the house through a door with a dead-bolt lock, wiping the doorknob and not locking the door.

Freshman Orientation and the Inventor of the Zipper - S4-E6

Plot hole: Memaw gets a call from Dr. Sturgis saying that he has moved to Waxahatchie and would she please call him back. He does not say the new phone number, and this was well before cell phones were in widespread use by the general public, so it could only be a land line. Memaw calls him back, although she could not know the number.
