How do I buy and find the right keys for my macbook unibody keyboard replacement?

Go to powerbookmedic website. Now they have make it very simple in searching for parts by narrowing down their inventory down to one specific computer which you have. You can even search by the Keyword Search option, Model Number option,Drop down menu option which is there. I suggest just use your drop down menu, from there just select your specific type of the computer in the Product Category type menu . Let’s say for example, I would click on MacBook Pro 15 inch Unibody. Next step is to select the link which says the Individual Keycaps. It will then take you to your exact keys which you will need, from there they have one little virtual keyboard where you can even click on the individual keys which you may need. Then just select one currency to pay, and then add it to cart and check out. They ship next business day, and it takes about 3 days to arrive to you.
