How do you evolve Onix in Heart Gold?

Question

how do you evolve Onix? I tried metal coat but that didn't work.

Answer 1

Metal Coat isn't the only thing you need.

You need to TRADE an Onix holding a Metal Coat for it to evolve. Then trade back, to recieve your all new Steelix

If you're looking for Steelix you can get one at Mt. Silver and the Cliff Cave

Answer 2

You have to either:

• Trade the onix to another trainer while it is holding the Metal Coat then get it back in a trade a second time.

• Trade any Pokemon with Jasmine to get a Steelix with a soothe bell. You first have to defeat her in a rematch and trade with her between 1 and 2 PM in game.
