You most likely had more than simple keyboard damage.

Follow the tags at right for an idea of what else could be wrong (corrosion) and what sort of DIY repair you'd be in for. ( FWIW Logic board replacement is a very advanced DIY project - you basically completely dismantle and then reassemble your entire machine).

In order to accomplish anything DIY wise you have to have a better identification of your machine. There are a lot of versions of the MB P going back beyond 2008 and in 3 different sizes!

After identifying the likely cause in order to fix it you will have to Study (not just read) the specific Guide, and notes for your exact machine, obtain the proper tools (every job is easier with the right tools), keep all the screws separate and identified so at reassembly you know which screw goes back into what hole.

If this answer is acceptable please remember to return and mark it.
