Patio doors are generally the hardest points in the home to protect against entry because they incorporate all the weak points of both window and door.

A garage door should be locked at all times whether you are at home or away. Use a good quality padlock to secure your garage door. If you have windows, use curtains. This will prevent potential crooks from window shopping for valuable property or expensive tools that might be stored there. It also prevents them from seeing if a car is in the garage while they are trying to determine if anyone is at home.
