I have a problem with my laptop's some keys.b,n,z,space ctrl and maybe some keys that I missed stopped working.I disassembled keyboard part and checked ribbon cable of keyboard, everything seems OK.
Why not try and check the warranty. You could be lucky and return it for a brand new one if not try replacing the key caps or using a sticky note to get rid of dirt.
Warranty is over.I've been using this laptop for 5 years
