Key facts and advice over sneak in burglaries from West Yorkshire Police
Doors and windows should be locked at all times - it only takes 60 seconds to reach through an open door or window.
Lock the doors, take the key out, don't leave it on view or in reach of a letter box or cat flap.
Always know where the house key is in case you need to get out in an emergency.
Don't leave bags, laptops, tablets or keys just inside the door.
Make sure everyone in your home get into the habit of being more secure.
