It doesn't seem to work. My door opens to the right

Asked by: Tish
Make sure to use the screws provided and make sure when its in the open or closed position it is all the way down in to the grove to prevent it from moving where you don't want it

Can it lock on its own it the door is slammed close? Is there any safety mechanism to keep it in the open position?

Asked by: BB47
No it will not lock you out. When open it has a small slit so that can never happen.

Customer Reviews

Satin Nickel Flip Door Lock is rated 4.4 out of 5 by 29.
Rated 1 out of 5 by from Not working My husband installed one on the front door and one on the back door. Neither one works properly and the door can be opened with a slight push. Its almost like the flap doesn't sit down in the grooves far enough and can be popped right out easily. Im very disappointed in this product.

Rated 3 out of 5 by from great concept but I have purchased other brands of this same door lock and they worked much better than this one. The one pictured is rather poorly milled and so you have to be precise in how you flip it to make it lock. If it were machined a little better it would have been perfect. Still, for the price, not a bad value as long as you are careful to make sure it is in the lock position when using it.

Rated 5 out of 5 by from Outstanding Service from HomeDepot and Great Product from First Watch Security First off, my hat goes off to HomeDepot for offering this product in every color and finish available and for offering this product with FREE Shipping! I had this product sitting in my mailbox four days later and paid less than $2.50. You can't buy anything on Amazon for less than $25 and get free-shipping (at least under most circumstances). Now for the product... It's a simple device and one designed primarily to keep the little rug rats from opening up the door and escaping the house. My primary purpose for using this lock was to secure an interior door on the main level of my house at the top of a staircase leading down into the basement. My basement is accessible from the outdoors and if an intruder were to enter into my house through the basement, he or she could quietly slip upstairs and into the main living area without being heard. Now this little flip lock isn't going to be powerful enough to keep out a willing and able bad guy, but it will create one heck of a racket if someone decides to kick down the door. This in-turn will create just enough noise to wake me out of bed thus allowing me the opportunity to grab my "freedom defender" from the nightstand. Installation is a breeze. It fastens into the door frame leaving only the swinging hinge exposed making for a clean installation. No holes are drilled into the door so if or when you decide to ever remove the flip lock, there won't be any visible holes except for the two inside the frame which can easily be filled and painted. There were two little additional screws which I could not seem to figure out what they were for. Possibly for a non-standard door installation though the instructions included with the product were not clear.

Rated 5 out of 5 by from Security Solution for a Toddler I was looking for something to install on the front door of my son's apartment that wouldn't cause a lot of damage, worked on a metal entry door, and prevented his overly intelligent 2 year old daughter from walking out the front door by herself as she's already figured out the locks. This was perfect. It attaches to the wooden frame of the door and latches the door shut. It's easy for adults to open but is placed high enough to be completely out of her reach. Best of all, it's an inexpensive solution that the apartment management allowed.

Rated 5 out of 5 by from Works great to ensure young children can't open door out to pool Bought a similar product 25 years ago for our previous house to ensure our young daughters couldn't get out to the pool. This product is made just as well, doesn't mar the door, and is an added measure of safety above and beyond the annoying door alarms required to meet pool code laws. Never have to worry about changing batteries, alarm sensor failing, etc.
