I have a door bell in the hallway which cannot be heard in other parts of the house and would like to set another one elsewhere in the house using the one button at the front door. Should I get 2 new chimes the same and a different transformer. I do not want wireless only wired

Here is a video that explains how to do what you want to with your doorbell. Tap on or click on the blue link. Or you may be able to buy a new 2 bell system. I hope this helps. Good luck! https://m.youtube.com/watch?v=Z1ggKCQc1i
