Wires to short

Ok, this is what I'm trying to do. I have a 2nd generation ring doorbell and the wires that come outside of my house for the doorbell are way too short. So unless I want to tear up a big hole in my wall and I have to solder wires, I'm going to have to hook it up wirelessly. My question is is there any kind of adapter or any some sort of extension that I can put so that my current doorbell system would ring on the inside the house? That way I don't have to buy a chime from ring. The current doorbell system is nice and loud and you can hear it through the whole house. I do believe that is a mechanical doorbell not digital. Any help and advice would be appreciated.
