Some keys not working on laptop keyboard

[TheoT]

So last night I decided to clean my setup/laptop and the next day when I opened my Sony Vaio SVE series,while I was trying to ctrl c something I noticed the left ctrl was working but the right one was.Then I used on screen keyboard and It seems that esc and some fn keys weren't working as well.Now I'm using a different wireless keyboard and all buttons are working normally,but I'd like to find a solution for this.
Things I've tried:
Blowing keys with compressed air
Restarting/Holding power button 20s when shut down

Try resetting cmos by removing the battery and connect psu only then hold power button down for 15 seconds to reset cmos. The other method is disconnect psu and battery and hold power button down to discharge which can also reset cmos.

try system restore to before this started.

 

[TheoT]

As I said,resetting cmos did not work.Unfortunately I cannot do a system restore.

 

[ffg7]

in what way were you cleaning the laptop as in just surface wise or disassembly.

 

[TheoT]

I did not disassemble the keyboard,I just sprayed underneath the keys.

 

[ffg7]

with what, some type of liquid?

 

[TheoT]

I used white Ajax cleaner which is for glasses but that doesn't really matter,right?

 

[zer0c00l587]

Only use an air can and non static brush to clean a computers. Ajax sprayed under keys can affect circuitry. I recommend finding a technician to disassemble and check the keyboard, its possible cleaning key board connection inside with pure alcohol will solve the issue.

 

[TheoT]

Well I sprayed Ajax on top of the keyboard so It might have affected the keys as well,then I used air can to clean underneath but there was no success.I could disassemble the laptop but what do I do after that?

 

[zer0c00l587]

I'm not good with electronics repair, I've seen a friend repair water damaged iphones which is far worse.

TheoT, what is the model# of your Sony Vaio laptop to source you a new keyboard? had to do same for a customer who spilt water on his keyboard after he attempted to upgrade his win7 laptop to win10 & it screwed up. both enter buttons would not work.

 

[TheoT]

Well the model number is Vaio SVE1512p1eb.Is changing the keyboard necessary or is there any way It can be repaired without It a new one?
