Try this. Just pretend you are standing on the front door step and you have discovered your house keys are not in your pocket* / *manbag / handbag* etc (*delete as appropriate 😁). Short of calling a locksmith….. How do you get in?
1. Key under the flower pot? Brilliant… But guess where someone wanting to burgle your house looks first?
2. There’s a window round the back that doesn’t close properly… Handy for you but…. hey wait a minute… handy for everybody including that guy that’s just checked your flower pots! The list could go on. Think about it. If you can get back into your house without keys, then so can somebody else. Do something about these vulnerabilities before it’s too late.
