You might not be aware of how simple it can be for a burglar to break into your home. Some are obvious, but there are also several surprisingly easy entry points burglars can use to gain entrance. Below are six entry points you should check in your home to make sure they’re secure:

1. Doors: As the U.S. Department of Justice’s Office of Community Oriented Policing Services (COPS) states, burglars often gain entry through unsecured doors, using screwdrivers or crowbars to break through. Also, some doors, like interior and exterior garage doors, might be unlocked, making it all too easy for burglars to get in. Doors in general can be kicked open, so you might also consider installing kick-resistant doors. Last but not least, remember to lock your doors, and keep in mind that knob locks are easily opened using credit cards, so you should have deadbolt locks.

2. Sliding doors: COPS states that along with unsecured standard doors, unsecured sliding doors are ways thieves gain access to a home. Heavy rods in sliding glass door tracks prevent these types of doors from opening. You can also have a professional install mechanisms to prevent tampering, as well as screws to keep frames and doors securely in place.
