[I need radio code]

Good evening everyone! I come to this forum unfortunately with a small problem. My brother changed the battery in my Honda CRV, then my radio got stuck. I should mention that I am on holiday in Bulgaria. I went here to the dealership and they charged me around 45 pounds, converted to BGN. Of course I didn't pay the amount, and I started searching on the net where I could get the code. I found a website, I'll leave the link here : https://autoradiocodes.com/honda-crv/ and I want to know if it's a good idea to buy from here, or if it's a free way to get the code. 

 

I'll leave some pictures here of the car and the message on the radio
