Need to Replace Back of Key Fob... Help?

Hey everyone,

The back of the plastic key fob for my 2007 Honda Element EX came off last night in New Year's celebrations (don't ask) and I need to replace it, as it has gone missing. The fob still works-- I bought a new 2025 battery (that fell out too) and the key fob works when I hold the battery down. (The battery won't stay put because the back piece of plastic is gone.) Do you all know where I can purchase a new back piece of plastic for my fob?

I haven't seen any for sale on the internet, but I have seen a rubber-like protector for the key fob. Perhaps that might work, but I am not sure how tightly it will hold the battery.

Thanks in advance for the help.
