How to Secure a Sliding Patio Door
When it comes to security, it is usually not a problem with hinged doors. A proper deadbolt will do the job for most homes. But for sliding doors, you may need more than the hardware that comes with the door. Sliding doors can be forced or removed from their tracks. And this is where auxiliary locks come in and there is a variety to choose from.
To keep the door panel from being forced to slide, Sliding Door Thumbscrew Locks are a cheap and easy fix. There is no tools or drilling required. The device simply tightens down to the lower track with a thumbscrew. This prevents the door from sliding even if it has been unlocked. For added protection against removal from the inside, some come with allen head screws instead of thumbscrews for fastening to your sliding door track. Of course, there are disadvantages to this solution. Since these locks aren’t permanently attached, they could get lost, but they still add protection to your patio door for under $5.
Another low-priced security device for your patio door is a Security Pin. This requires a little more work to install, but not too much. Drilling a few holes will do it. The security pin is basically a pin that you insert in a hole that you have drilled through both panels of a sliding door. When the pin is in place, the door will not be able to slide or be lifted out of its track.
A Loop Lock locks your sliding patio door to its frame similar to the way a chain lock secures an entry door. It also requires a little bit of installation time.
A Bolt Lock attaches to the bottom of the active panel on your sliding door with screws. It has a spring activated bolt that locks into holes you have drilled in the base of the active panel of your sliding patio door. The advantage to this type of lock is that you can drill multiple holes for both fully closed and vent positions.
An Auxiliary Foot Bolt takes convenience one step further. The lock is activated and deactivated by stepping on it, which means no leaning over to secure your patio door.
Many of the locks listed above also come in a keyed variety for added security.
Then there is the variation of the old broomstick, the bar lock. These are considered jimmy-proof since the bar prevents all movement of the sliding panel.
