Dont leave your keys in the inside of your lock especially if you have a glass panel either side of the door.
A thief can break the glass and reach inside and open the door.
If you need to have your keys close at hand then attach a hook near the door ,but it is preferable to not have keys visible just incase they break in via the roof which then allows them to escape with vyour large items via the door
