Police have been reminding people to lock their car doors.
They wanted to see if the message was sinking in.
The Wellington County OPP walked through a neighbourhood in the Town of Erin last Thursday night.
Of the 100 vehicles they checked, 30 were unlocked.
They also found two unlocked trailers and two open garage doors.
Police again urge everyone to lock up and remove all valuables from your vehicles when you’re not using them.
