Will this work for a powermaster mg-51? or do you habe one that will?

This should work for any door as long as it had a purple program button. If it has any other color look up opener for that color they are out there

how do you replace the battery?

I really like these. They work great but haven't even replaced a battery yet.

What brands of garage motors does this remote control work with?

This remote works with Chamberlain & Liftmaster & Sears Craftsman openers manufactured from years 2006-2014 that feature the PURPLE Learn Button.

Can we copy the key from existing key?

This replacement device is simple - it is designed to pair with the Chamberlain garage door opener. It is not designed to learn a different code from what is programmed at the factory.
