It takes only seconds to install a Lion Lock on your sliding glass door. There are no moving parts, no tools required, and no holes to drill. Its easy installation makes the Lion Lock an excellent choice for renters or anyone in a temporary living situation.

The Lion Lock fastens tightly with two simple thumbscrews and a secure rubber grip that clings tightly onto your door’s track. This prevents the door from sliding back far enough for someone to slip in or out.

We found one design flaw with the Lion Lock. It blocks access for those trying to get in by stopping the sliding door, but it’s easy to undo from the inside. So kids, teens, or other adults might be able to loosen the thumbscrews and open the door to go outside.

Lion Locks come in packs of 10 so you can secure your windows too. They can hold up stubborn windows or keep others closed, depending on your needs.

If you live in a home with a pool or balcony on the other side of a sliding door, your child might be tempted to explore without you around. That’s why babyproofing your home is so important. Items like the OKEFAN baby safety lock are a smart way to keep littles safe without restricting your access to areas outside.

The OKEFAN Baby Safety sliding door lock is a simple peel-and-stick device that works with sliding glass doors, cabinets, and more. Stick it on the glass panel to block the sliding door. Then when you want to open the door, press down the pedal and slide back the door. We suggest installing the OKEFAN out of reach of your kiddos to avoid any accidents.

Because it’s made of plastic, this sliding glass door lock is designed to keep people in more than out. If you want to boost security, the OKEFAN lock can help, but it’s not as tough as our other picks.

While the BK110 Security Bar requires some installation, it’s something you can finish before the commercial break’s over. The SK110 sits horizontally on your doorframe to block the sliding portion of your patio door. When you want to open the door, lift the bar and set it vertically on the other side of the door.

The BK110 also comes with an optional childproofing tab that makes lifting the bar difficult for little fingers. It can’t keep everyone inside though. Adults and teenagers can use this bar pretty easily, which is good and bad.

So while the BK110 won’t stop any teenagers from sneaking out of your home, it will block intruders from entering your sliding patio door or taking it off the trackB
