They look good and both work just as advertised. The directions take a little figuring out for the programming. Kinda written in a backwards manner in places. The installation was great! Easiest combination lock I've put on - and I've done several Schlage models. Extra parts came along with this - including 3 keys and a screwdriver.Downsides? Hmmm, the keypad is not lighted - but not an issue for our location. This lock probably doesn't look quite as upscale as the Schlage model on my front door - but it still looks very good.Bottom line for me was the ease of installation and the perfect functioning of these locks for thirty days now. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars The buttons also do not lose the numbers to wear like some others *by N***I on Reviewed in the United States on June 3, 2018* I have been using this lock on my front door for for about 18 months. It has had no issues except that the latch broke after one year but I contacted the seller and they responded right away and sent me a replacement and a spare. The lock body is very solid and the buttons respond accurately. The buttons also do not lose the numbers to wear like some others. I bought this because it cannot be picked or bumped by means of the bypass key. It does have hidden bypass key opening but the key is a shape that I have never seen before and neither would any criminal (I have cut a lot of keys while working at a hardware store). Having said that, it is not a dead bolt and does not offer the security of one. It is extremely convenient to never wonder if you or your kids remembered to lock the door. The battery life also seems good. I have had to replace the batteries only twice in 18 months and we use the lock probably an average of 20 times a day. It also has a low battery alert that you can't miss. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Well thought out. Meets my requirements *by M***S on Reviewed in the United States on November 10, 2017* This is a great lock. True, I just installed it today but it is very stout - heavy stainless steel, it has an ability to have digital codes up to 13 digits where the correct number in the correct sequence must be entered. It also allows up to 9 users with different codes. It is very easy and very straightforward when it comes to changing the codes. And the lock is complete with 3 keys in the event there is a need as well as a way to power it externally... which I can't figure a use for but it is there. And if you forget everything, there is a way to reset the system - albeit you have to work a bit to do that. It is relatively easy to install and has rubber type mats designed to go between inside and outside knobs, thus protecting the door and securing the latch from water intrusion. However, the entire inside of the outter lock is covered with a steel plate which in its self makes the unit water resistant. Well thought out and heavy duty ... this system met my needs and then some. You will need 4 AA batteries... --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/522073529-haifuan-digital-keypad-door-lock-with-backup-keys-electronic-keyless](https://www.desertcart.vn/products/522073529-haifuan-digital-keypad-door-lock-with-backup-keys-electronic-keyless) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-17*
