MacBook Pro 13" mid-2010 Canadian replacement keyboard ?

That's so specific. I'd call Apple customer line. Ask them how to get one. The electronics need to be swapped as well and I know Apple has been using all kinds of various versions of keyboards from 2008-2012. It used to be easy with the aluminum keyboards and powerbook boards as you could just lift them out and and plug the new board in. You're going to have to remove every part in the computer to get at the keyboard/ top case as they are virtually 1 now. Then there is the 50 screws to remove. Usually Apple replaces the entire top case. Replacing keys only is like solving a Rubics cube by removing the color stickers. And there is a good chance you'll break one.

So you want to replace the physical key corresponding to the french canadian keyboard layout and then switch the international layout to french canada? That may work fine. Those keys are fairly fragile. Get your method down Hinges may differ between 2008 and 2010. It looks like the return key definitely wont fit. The pic looks totally custom and WOULD require a new top case if you wanted the off sized keys.

 

Yeah . I thought I should look at the ebay link before spouting off
I'd still check with Apple to see how much to customize. Or maybe a 3rd party certified reseller. Chances are they will just want to sell you a new Mac though. Hey, project!

 

You're explaining just fine. I don't have an answer as so many small things can change on the keyboards each year and then added to it the international nature and changed positioning of the keys. Unless someone here has direct info on the exact years and language of same keyboards I don't think we can say anything for certain. You're going to have to take a slightly expensive chance. Or deal with it the way it is and get a FCanada board next Mac.

 

Good luck. But wait a bit before making a decision. Give some time to other French Canadians who may be able to help answer your questions. Maybe a few days. Bump the thread to keep it from getting buried. If no response, well, you're on your own.
