You have checked all the windows to make sure they are closed and locked, doubled-checked the doors, let the neighbors know you are going out of town, informed the mail so it does not pile up and activated all the passive security systems in your home. However, one area is often overlooked as you pull out of your garage and leave: The garage you just left.
A modern-day garage is a prime spot for thieves to gain access to your home. 
There are three basic types of garages that your home may have and each one requires its own safety measures. The first two are attached garages, and they can be divided into two categories: The front of the house garage that faces the street and the rear garage, which is out of view from the street.
The third type of garage is the detached garage. It is particularly dangerous if this type of garage is not secured properly because it offers a staging ground for thieves to enter the premises.
Here are a few pieces of advice that will help you protect your home:
Use Your Garage. Park your car in the garage when it is not being used or if you are leaving by other means. Many people leave their garage door remote in their car, and all it takes is something like a broken window in your car to give a thief access to your home. To combat this, you can also make sure to remove the remote if you leave your car outside of the garage.
Disable the Electric Motor. If you are leaving for an extended period of time, detach your electric garage door opener. This is usually a very simple thing to do. Most electric garage door openers have a rope or chain you pull down to disconnect the electric motor from the chain that operates the door. This protects you in two ways: First, if a thief used a frequency scanning device to obtain your code, it will be of no use since it is not operable. Second, it would require a thief to physically go to the door, which the neighbors could see.
Bolt It. Use a manual sliding bolt-style lock on the inside of your garage door that can only be opened from the inside.
Keep It In Good Condition. Make sure the garage door is properly functioning and that there is no damage to the panels through which a thief could access your home.
Keep It Contained. Do not leave important items in the garage and make sure to lock the door to your home. If thieves do break into the garage, you want to make sure that is all they can access. Place a deadbolt and anti-kick device on the door that leads to the garage.
The Same Goes for Detached Garages. For the detached garage, make sure you follow the same principles as if it was connected to your home. If the garage is out of view from the street where neighbors could spot a break-in, these rules become even more essential. Most importantly, do not keep valuables in your garage
