Primus is next to impossible to transform without that stupid planet key. Though casting a copy with electronics might not be cost effective. BUT, casting some replacement lock with the bottom tip might be. Just something that can be used to transform thie toy in case the planet lock is lost. Seriously, which HasTak employee thought the lock thing as a necessity was a good idea? You cannot transform the toy without it. At least with Powermasters you could just push the obviously exposed button bit to transform the toy(not that it wasn't also dumb).
