Hangcheng Left Handed Mechanical Door Lock Combination Left Handle Keyless Entry Door Lock-NOT a Deadbolt & Need to Drill Additional 4 Holes & Only for Single Bore Door

To start, the manufacture went through a lot of extra steps to make everything easy, like putting extra hardware in the bag in case you drop, or loose one. The instruction booklet is easy to read and they give you templates that tape to the door letting you drill holes exactly where needed. The combination can be changed by removing 2 screws from the back side of the unit, takes about 5 minutes. The construction is heavy duty. It has a lifetime warranty. It will be hard to beat this product for the price. Hangcheng Left Handed Mechanical Door Lock Combination Left Handle Keyless Entry Door Lock-NOT a Deadbolt & Need to Drill Additional 4 Holes & Only for Single Bore Door

I have purchased several of these locks. I like the heavy construction, style and price. I did have issues with a few of them but Amazon is great at returning items so I did not hesitate to reorder replacements. I use these at my vacation rental properties.

I bought this for an outdoor gate that leads to a courtyard before getting to my front door. I chose this because of no batteries or electronics to warp in case of rain. The combo is easy to set and the door performs as expected. Drilling the extra holes was not hard with the template it comes with. You do have to lift up on the handle to lock it after putting in the code otherwise it stays unlocked. The reason for 3 stars is it does feel a little cheap. I feel like I can brake this door lock if I press down hard with it being locked. I don’t want to do that but I’m pretty confident with how it feels pressing lightly down that if I give it full force I’m gonna snap the handle or the inside components will break. Wouldn’t recommend as only security if this was on your front door.

Don't buy this product. The handle broke after only a few months and now I can't get back in to the house. I need to call a lock smith. The handle broke off completely. I never write reviews but I never seen such a poor quality of a device that should be solid for the safety of your home the front door.

Keyless entry without batteries the only way to go. Always works rain or shine.

Works as intended. I have some items in my office that are not kid friendly. Installed this and it keeps them out. No more hide and seek lol

I like these. Tried a few electrical versions and they always seem to develop faults. These seem reliable and solid. Just a few points to consider if you plan on buying one:1. They can not be easily fitted to doors that are pre-drilled for a handle and separate lock so best to use these on an undrilled door.2. The template for drilling the screw holes is really confusing and difficult to use. Measure twice before drilling!3. the combination is set manually by changing out little pins inside the lock assembly. So, to change to code requires that you sis-assemble the item which might be undesirable for some people.4. Combinations do not allow for the same number to be used twice. each number needs to be different (it can be set for 4, 5 or 6 numbers) Also, you can not set the order that the numbers can be pressed to open the door. If your code is 1-2-3-4, then any combination of those numbers will also open the door: like 3-4-1-2; 1-3-2-4 or any other combination.Overall it is a nice, sturdy door set and I'll be buying more.

It works, but, the instructions are poorly written (probably an English translation of Chinese) and the template is difficult to use. Most problematic is that the 4 holes are difficult to line up for the interior and exterior plates, posts were bent when delivered and I had to bend them back by hand. Key advice, insert exterior plate and the number pad into door holes at the same time, then attach the interior plate leaving all 4 loosely attached THEN screw them all together...contrary to instructions.
