Getting Xbox Elite Controller replaced

Is it a standard controller or an Elite controller?

If it’s standard you’ll have to replace the controller unfortunately. If it’s an elite you can get it serviced or replaced if it’s still under warranty.

I would like to get this controller repaired but I can only find ways to get a replacement. This is a xbox design lab controller so idk if they're gonna replace it, plus the serial number didnt show up when I punched it in. Is there an easier way to get a replacement or a fix for this elite series 2 controller?

Microsoft Complete covers your Xbox One console, plus included controller, against accidents and mechanical or electrical breakdowns for up to three years. For covered controller and console, you get up to two replacements of a standard controller or one
replacement of an Elite Controller, and one replacement of the console – no deductible required.

Check out the Servicing your Xbox Elite Wireless Controller page which you can find here:

support.xbox.com/.../servicing-elite-controller. You'll most likely have to use the Xbox Online Service Center to try and get your replacement.

They give me no options there other than buying replacement parts for the swappable components (thumbsticks, paddles, d pad). Nothing about repair of the unit itself or replacement parts for the internals.
