There are various designs of sturdy, supportive glass door locks on the market. They not only provide a safer anti-theft function but also help keep your children away from outdoor activities. Adhesive door locks, pin locks, mortise locks, and bar locks are some of the many designs of sliding glass door locks.

How To Choose The Right Sliding Glass Door Lock?

Here are a couple of things to keep in mind while buying a sliding glass door lock.

  1. Strength: You must buy a sturdy lock that can restrict the patio door while also supporting it without breaking. Pin and mortise locks are robust and provide enough strength to prevent intruders from entering your home.
  1. Size and thickness: You must consider the locks’ size to see if they fit your window or doors. If the locks are too thick, opening the door may be troublesome, while a lock that is too thin may not achieve its purpose.

Frequently Asked Questions

1. How to fix the sliding glass door lock?

Mortise locks that are most commonly used may often bend, and the best way is to replace them. Remove the lock and handle by unscrewing it from the patio door to identify the dents. If the lock is too bent, you may need to replace it with a new one.

2. How do you lock the sliding glass door from outside?

It is best to install a sliding door lock inside, but it is best to install a lock that opens with a key if you also need it outside.
