FlipLok High Security Door Lock - 10X Stronger Than a Deadbolt, Keypad Lock, Silver, Keyless

This door inner flip lock is a game-changer for home security and has become my favorite purchase for that very reason. Its design is practical and sturdy, typically involving a pivoting metal bar that secures the door from the inside. Functionally, it acts as a strong secondary lock, providing a physical barrier that makes it much more challenging to force the door open. This simple addition significantly enhances your sense of safety. The good quality materials and solid construction ensure its long-term reliability. To maximize its impact on door security, using 3-inch screws for installation is crucial. These longer screws provide a much stronger anchor into the door frame, making it far more resistant to forced entry attempts. It's a simple, effective, and highly recommended security upgrade.

I have used numerous versions, types, and brand flip locks throughout the years. This one is leaps and bounds ahead. I bought this one to solve an odd shape, thick exterior door (it had a deeper mount plate than any I'd found/bought). To my surprise of all the adjustment pieces you get with this to fit almost any configuration. This even includes loctite which is crazy in today's market.Pro: Super easy installation. They have it built where you don't really need to do anything other than placement on the door (it doesn't really say but you'd put it about 3/4 up the door from the floor but at least 4-6" from a deadbolt install, you'd position it lower based on children sizes if applicable). Quality is top notch. Durability (force it withstands) is almost 3x higher than like items (and its clear once you install it and pull/push test for give). Ease of operation is also great. Especially if someone has limited use of their hands (hand strength or mobility). Maintenance should be worry free unlike the ones that are spring loaded. Color choice of nickel is really spot on in comparison to other hardware of same color (so it matches).Con: It's a bit pricey at $60 but the piece of mind is worth the premium. Nothing else at the time of installation. Of note, but not really a con, but because it slides up/down on the door, you may wat to consider felt tape so it doesn't mark/scratch your door.In conclusion, I'm overly shocked with the quality on this. So much so, I'm buying 3 more for exterior doors at my house and 1-2 for interior doors (it comes with a different mount plate to fit interior door thicknesses). If you, or someone you know, uses these types of barricades for added security or is looking to purchase them...look no further, and/or direct them here (i just finished installing it about an hour ago and I've already told 11 people). I will get others for my mother/father-in-law's houses. 100% recommend this to everyone.As an added bonus, I have an exterior door that closes too tight so it puts a ton of pressure on the deadbolt causing it to need replacement less than every 7-10y. With this, I mounted it just as tight so when you push the door in for the fliplok to engage, it is tight enough that the deadlock has smooth operation again.

Finally a product that delivers the confidenceof a secured door. Easy to use, quicker than turning the deadbolt. Installation was a bit tricky due to my door frame decorative molding. On a flat door jam, easy and quick to install. The parts are perfect, including the tube of blue lock-tight. TheInventor thought of everything. I'm very impressed and pleased with this purchase, including the 4" screws for securing the plate to the framing studs.The short screw for lining up lock really helped to make sure everything was perfect!!!!!

I bought this lock after returning a similar but much cheaper add-on lock (if you’re reading this review, you’ve seen it- they are all over Amazon) that once I received it, I realized used a spring mechanism. That’s a no-go for me since it’s a potential failure point. This lock, however, has no springs and no real potential failure points. It is VERY robust and made of a very thick aluminum. It also includes an extensive set of installation hardware, and good, detailed instructions. You can tell a lot of thought went into this design. So how does it perform? I can tell you the door I installed it on is now probably the most secure in the house. Very strong, and very simple to use. Great design. I’ll probably buy more for other doors.

Great product. Installation directions not as complete as could be, but the instillation was easy.

Wow, this is one of the nicest door locking devices I have ever seen. It functions effortlessly, both to lock and unlock. The install goes smoothly on MOST doors, some doors don't have a wide enough gap (because of age or poor door install) but it can be "cut to fit" into the jamb if needed. My only problem with this locking device is the PRICE. When you get your lock delivered and open the shipping box you will notice a beautiful product box. As you open that box, you almost feel that you are opening a box designed for a Rolex watch or other extremely expensive piece of jewelry. Don't get me wrong, it is packaged beautifully but if they did away with the fancy packaging, they could probably knock off $5.00 or more off the overall price. The lock is well made, works for both right and left "inswing" doors" just by flipping the locking head over (takes 10-15 seconds) and is VERY strong. Guys, just remember to not piss off your spouse or you will literally be "sleeping in the dog house" until they let you back in.

Easy to install. Works like description says. High quality!!!

Easy to install and secure your door so that no one should be able to open it
