If you have factory reset the chrome book and it asks you to re-enroll the device, your only option is to contact the seller unfortunately. Most companies will have the option set that they have tk be re-enrolled to their domain, you know incase someone steals it and sells it on Craigslist ?
Make sure you do the pair if you do decide to do it yourself. If you change out or repair the broken one, I always find that one is then stronger than the other and that one breaks within a year or two anyway (generally they sell them in pairs anyway).
