To change the code, I struggled; the instructions are very bad, that's why one star less.
1. I press reset on the back of the door.
2. While it is still on, I press a 4-digit code that I want and at the end A, I repeat it once more

I've had it for 1 month and I use it almost every day; for the money, it's great. Anyone who wants more security should look for a safe over €300!!

Quite simple and easy to use, which I consider very positive as it was purchased to be installed as a provision in Airbnb. However, the quality of the materials could be slightly better, it seemed very lightweight to me. I have installed it and cannot have an accurate opinion now about the weight because I did not weigh it before installation, but I have doubts about the 5.6 kilograms...

Quite good, easy to install. Excellent shipping process via Skroutz point. No need to wait for the courier
