You have to trade your Onix while it's holding the Metal Coat. Trade it with a friend and trade it back and then you will have a Steelix.
You have to give onix the metal coat and trade but only works if you have national

Give to him Metal Coat and trade to a friend, get it back and he's now a great pokemon...steelix
You have to trade it into another game. It will evolve into a steelix. Now trade it back itnto your game.
This is how you can get him to evolve!!!!!!!
Do what those other people told you.
But I don't want to trade. I have nobody to trade. I'm on an emulator
