Hi @SLott
Welcome to the HP Forums!
Thank you for posting your query in this forum, it's a great place to find answers.
I reviewed your post and I understand that you want to know whether you can use the wireless dongle of your keyboard with a different keyboard.
Don’t worry, we will work together to resolve this issue and It’s a pleasure to assist you in this regard.
I would like to inform you that the wireless dongles are designed to work with only the keyboard/Mouse they are shipped with. However, as you have mentioned that it’s the same keyboard model you can give it a try.
Hope that answers your question and you have a great day!
Take care.
Cheers!
