CODACE Keyless Entry Door Lock with Keypad Deadbolt, Mechanical Keypad Door knob Lock with Handle, Digital Code Door Lock, Combination Gate Lock for Outdoor Fences Front Door, Not Electronic (Black)

Update 8/29/22:Lock stopped working completely. Horrible product. Don’t bother.If I could give a negative 100 stars, I would.First, I have installed dozens of deadbolt locks before so this is not my first.I want to point out to potential buyers of this design flaw: The deadbolt latch is ~24mm (see attached figure #1). Under the instruction for "Installing the Latch", step 2 says "... drill a 24mm diameter hole x 86mm deep hole". The latch inserts into the 24mm drilled hole with no problem. The problem is that when you engage the deadbolt to open and close, a mechanical piece protrude outside of the 22mm diameter, where at the center it reaches 35mm (see Figure 2). As you close and open the deadbolt, this piece traverse a semi-circle that reaches a maximum height of 35mm (see arc drawn in Figure 3). Without drilling whole that is 35mm, there is no way the deadbolt can open or close because 24mm hole does not clear 35mm!!!! All deadbolts design I have install have all mechanical components staying within the deadbolt encasing, i.e., the diameter of the deadbolt. Also you cannot just drill a bigger 35mm for this to work because doing so would create a hole too big and would intersect with the two screw holes that secures the latch face plate. (Additionally, I've included Figure 4 showing the the 24mm whole and how the engaged deadbolt will not clear.)To deal with this flaw, I had to drill/carve/cut out basically (from the front of the gate) the arc shown in Figure 3. You have to do this very carefully as shown in the drawing of the arc because if you accidentally go a few mm lower, you'll hit the opening hole where spindle inserts into the latch -- inviting just more disaster.Anyway, you get the idea. This lock sucks.

Very easy to use. I like it

Called a locksmith to install, he didnt want to bother with it. Installed myself, surprised how manually cut a piece off to make it fit standard width door, but oh well. Worked great at first, as most mechanical cipher locks do. But soon, the "C" button (which resets mechanism for code entry) had to be pressed more and more times to achieve a reset, then after a few months just stopped working reliably. No longer trust it to unlock so it is essentially unusable. The housing seems solid, but the internal mechanism is low quality. Will be getting some other brand instead, not sure which.

This lock works for a couple months, and now the buttons do not press. It is essentially unusable. Waste of money.

This Lock is Junk! I put it on my side door. Worked for a few days then would no longer work with code programed. Re programed it with a different code. Worked for a few more days and broke. I still had toe original box. When I tried to return it defective they told me I had it too long. I would not recommend this JUNK to ANYONE!
