Review: Buying this again. - Pretty easy to instal and has worked flawlessly for over a year. Good purchase.
Review: One out of the two of the same lock I bought opened with ANY combination until I did reset it - I bought two of these locks last summer and I've been using them since then and I've been very happy with them as they look super cool and worked just fine and I thought that they're well worth their price compared to other locks available. Since I only used the combinations that I set them up with to open them, I haven't realized until recently, that one of them actually opened with ANY combination. I set mine up with a 6 digit code, but then I had realized that any code, 4 digits or more, actually opened the lock, just the same and I had been living with an entry door that could've been opened with any combination by anyone, for almost a year. When I noticed this, I had started to use an additional mechanic lock to keep my door safe which kind of defeats the purpose of having the keyless digital lock in the first place. Since the return window on this lock had already closed, I contacted the seller about my issue. They sent me instructions on how to reset it, which I did and since then my lock works perfectly. The reset can be done only from the inside, so it's safe. I wish I had known this a while ago, but eventually the issue got fixed and I'm happy with my lock again. I still recommend it and still think that this is one of the coolest looking lock which well worth it's price.

### ⭐⭐⭐⭐⭐ One out of the two of the same lock I bought opened with ANY combination until I did reset it

### ⭐⭐⭐⭐ it works at normal temp less than 90 degrees
*by T***Y on August 29, 2024*

I gave this 4 stars for the sellers, but 3 stars for the product. The lock does not work if the temp real hot, 90 degrees outside (if uses as an exterior lock). I must give the company who sells it props, for standing behind their product. Why? After installing the lock for 1 year, I decided to now install the batteries. Only to find that the electronic features did not work. I contacted the company, and they send me a replacement. The replacement also failed a few days later. Then I notice it only works when the weather was cooler.
