Every year thousands of homes are burgled but unknowing many of us are helping the crooks do it.

Nearly one in three of us regularly leave a key hidden outside our home, often in very obvious places such as under a plant pot or door mat.

More than 6000 burglaries take place each year where the thief has not broken in but instead gain access using a key.

Even when we do not leave keys hidden many will leave keys close to the front door and in plain sight through the letter box or open window.

Should you have to leave a key outside then a police-approved key safe is the only safe option.
