It comes following reports of sneaky thieves hellbent on swiping vehicles using fishing rods to obtain the keys through letter boxes.
A Police Scotland spokeswoman said: “There has been an increased number of reports this week throughout North Lanarkshire that cars are being stolen using a key which has been stolen from within the house.
“This is done by means of a fishing rod or similar instrument reaching through the letter box removing the keys.
“Please be extra careful where you store your keys within your home. Keep them in a drawer or room away from the front door.”
