Lake County (Illinois) News-Sun – “Police: Burglars target garage door openers for home access” – May 29^th, 2014:

Gurnee police have put out a Crime Alert warning residents of a residential burglary trend in which thieves target unlocked cars and grab garage openers to enter the home.

Two recent burglaries on the northeast side of the village have followed that plan, according to Gurnee police. In one case, the car was stolen, too.

"It’s unique,” said Tom Agos, the department’s crime prevention specialist.

The incident in which the car was stolen hasn’t been solved, but police did recover the vehicle in Waukegan.

In each case, a garage door opener was taken from an unlocked car parked outside to gain entry into the garage and then into the home, police said. The doors between the garage and home were left unlocked. Both cases happened overnight while the residents were home asleep.

“It seems elementary, but both crimes could likely have been thwarted had the parked vehicles been locked,” Agos said.
