ST. CHARLES, Mo. (AP/KMOX) — Residents of Westhampton View Court in St. Charles County have solved their garage door mystery.

Shortly after Christmas, garage door openers stopped working at the five homes on the cul-de-sac, drawing significant media attention.

The St. Louis Post-Dispatch reports that neighbors Gil Ballman and Hannu Heinonen figured out that a transformer for one of their landscape lights was emitting a signal that interfered with the frequency controlling the garage doors.

“All of a sudden I heard a garage door open, and I thought, ‘This is wild,'” Ballman told the Post-Dispatch. “I said ‘Hey, guess what? It’s you Hannu.'”

The culprit turned out to be Heinonen’s 24-volt transformer box that he installed four years ago.
