Rated 1.0 out of 5.0 by Does not work on Vinyl Doors This product did not install at all. This should have a large disclaimer saying it works great for wood windows, but very poorly on vinyl. The spacers, which I needed to use due to my jamb length, were a joke (cheap plastic, which bent when any torque was applied to the screws). The bracket made the door unable to close, until I bent it with a hammer. The lock part was unable to attach to my sliding door at all, which has a steel core behind the vinyl. I ended up having to use washers for the spacers, and double stick tape to attach the lock to the door itself, which I am lucky I had at home already. For a $30 product, I needed to improvise to get it to even work, which is aggravating when you spend so much. Also, with the double stick tape, it does not provide any real security. We mainly bought this as a child lock, so it works for this purpose, but I would not trust it against a burglar. Also, more companies need to learn from Ikea. Diagrams speak louder then paragraphs of words, but a small picture of a woman holding the unit against the door is not even close to sufficient. Simple diagrams are very helpful, and should be used more often instead of small black and white photos. June 21, 2014
Rated 5.0 out of 5.0 by Great replacement lock! The lock on my sliding glass door went bad and I was told due to the age of the door I needed to replace the entire door. I was able to remove the existing lock and replace it with LOCKiT. The ONLY complaint I would have is the color of it. I would have liked it to be completely white to match my door. But it still looks great even with the small amount of black in it. In my opinion, it works better that the old lock and is way more secure. May 15, 2013
Rated 5.0 out of 5.0 by Simple and secure I have installed 2 of them. One of them on two sliding doors that meet together, and the other on a single sling door. Both the same, simple installation. Highly eco mind this product June 16, 2015
Rated 1.0 out of 5.0 by Problem with the lock The bolt apparatus screws were too close to the glass and shattered the door. $330 mistake. July 22, 2015
Rated 5.0 out of 5.0 by Thank You Now I Can Sleep Pieces can be reversed for installation. Works great! October 3, 2014
Rated 2.0 out of 5.0 by Didn't work for me Could be a great product but neither of the jam brackets worked for my particular door. My sliding door jam is very shallow and neither bracket would allow my door to close completely such that I could also use the primary lock. I thought about just using this as the primary lock but again the door wouldn't completely shut tightly so I had an air leak. I did think of a possible way to use the wider of the two brackets with some minor modification to the sliding glass door frame itself but that forced a small part of the lock body to be positioned off the rather narrow glass surround frame which looked bad. Basically, it didn't work for me and you won't know if it works for you until you get it home , crack it open and see if the hardware fits. I also think it's about $10 overpriced. March 14, 2015
Rated 5.0 out of 5.0 by Measure your frame Bought three for my home but could not use them because the metal frame is too narrow (1 1/2") to allow attachment to be secured onto the door without drilling glass. Bummer!! Put one on a rental property and yes it does the trick. Too bad they don't fit some older built sliders. June 3, 2015
Rated 5.0 out of 5.0 by Saved us 700 dollars couldn't replace the lock and handle on patio doors that had been so badly damaged by previous owners. This product saved us from having to replace the whole door. It secures the door just like it says and for under 50 dollars! December 10, 2013
