A1278 is the model and 4 last nr is DTY3


I would suggest just replacing the Keyboard much cheaper, but a few more steps and then you have to be careful with the back light but it is still easy to get off the keyboard

This requires a keyboard replacement. The power button is not independent. To make sure we get you to the correct part please give us the last four figures of your serial number.


Apple MacBook Pro "Core i5" 2.5 13" Mid-2012 Specs

Identifiers: Mid-2012 13" - MD101LL/A - MacBookPro9,2 - A1278 - 2554*

You can either replace the whole upper case or just the keyboard:
