When it comes to manually locking your garage, the type of lock you choose is incredibly important. It’s essential to select one that suits both the style of your door and how often you use it. Sectional doors will require different locks than roller doors, so make sure you take a close look at what type of door you have before purchasing any security hardware.

For sectional doors, the best locks are padlocks or deadbolts. These are easy to install and require no special tools or equipment. Padlocks come in a variety of sizes to fit different door widths, so be sure to choose the right one for your door before installation. Deadbolts can also be used, but they require a more hands-on installation process.

For roller doors, slide locks are the most secure option. These simple devices latch onto the door’s track and prevent it from being opened unless the lock is removed first. Slide locks come in different sizes to fit different door widths and can be easily installed without any special tools or equipment.

Once you’ve chosen the best lock for your door, you’ll need to gather all of the necessary materials for installation. For padlocks and deadbolts, you’ll need

  • a drill with standard bits
  • metal screws
  • screws anchors (if needed)
  • a screwdriver.

2. Secure Metal Hardware

3. Install Lock

Once the hardware is secure, it’s time to install the lock itself. If you’re using a padlock, simply slide it into place on the hasp. For deadbolts, make sure the keyhole faces outward, and the latch is properly aligned with the strike plate before using screws to secure it.

4. Test Lock

Once the lock is in place, give it a few tests turns to make sure it’s working correctly. Make sure the keyhole faces outward so that you can easily lock and unlock your door from the outside.

5. Use Key

8 Safety Precautions When Manually Locking Garage Doors

When manually locking a garage door, it is important to take certain safety precautions to ensure the security of your home. Here are 8 tips for safely locking your garage door:

  1. Make sure that you close and lock any side doors or windows leading into the garage before attempting to lock the overhead garage door. Also, make sure that the door leading from your house to the garage is closed and locked.
  2. Ensure that the overhead door is properly secured to the track and cannot be lifted open by hand. If the door can be easily lifted, it may not be locked securely and could be vulnerable to break-ins.
  3. Make sure that there are no objects in the way of the garage door when you lock it. If there are any obstructions, the locking mechanisms may not engage properly and leave your garage vulnerable to burglary.
  4. If you have an automatic garage door opener, make sure that it is turned off before manually locking the door. This ensures that no one can access your garage without a key or code.
  5. Check the latch mechanism and ensure that it is working properly. If the latch can be easily opened, it may need to be replaced or adjusted so that it will remain secure when locked.
  6. Consider installing a padlock on the outside of the door in addition to the locking mechanisms inside. This provides an extra layer of security and makes it more difficult to forcefully open the door.
  7. If you have a fold-down ladder installed in your garage, make sure that it is properly secured when not in use. This prevents any unauthorized access through the roof or ceiling of your garage.
  8. Lastly, if you are away from home for an extended period of time, consider installing an alarm system or motion detector to alert you of any intruders in your garage. This will ensure that if anyone attempts to enter the space, you will be alerted and can take steps to secure your home.

By following these tips, you can rest easy knowing that your garage is securely locked and protected from unwanted visitors. Take the time to ensure that the door is properly locked and secured, and your home will be safe.

Consider Installing a Padlock
