On my wifes keyboard(microsoft "ergonomic elite")some keys don't work. I've tried some compressed air as well as connecting it to another computer,holding down the num-lock key during a boot and still the same results. I know that I can buy another one however, I'm curious to see if there's a fix for this.Please help. Thank you!.

Re: some keyboard keys don't work
You don't say which keys don't work and if the keyboard is more than 1 year old you may open case via the screws in back of keyboard please note down the keys that don't work then the keys that you don't use that often just swap the rubber conntacts on them if yours has the rubber membrain it needs to be sent back to the manufacture of the keyboard to have them replace the membrain but if the keyboard is in warrenty then get it sent back with the details of sale.
look for all screws they may be hidden.

Keyboards can become dirty over time. Use some compressed air to blow underneath the keys, there could be lint or dirt stuck under them which would prevent them from being pushed down fully. If the keyboard is many years old it could also be worn out with time.
Sounds like you solved it yourself. NEVER use a wet anything to clean electronics, water and circuitry were never meant to meet.
You will most likely need to replace the keyboard, that being said if you need to clean it again in the future use "canned air" compressed gas to blow out any dust and debris and if you must scrub it down, disconnect it from the computer first, use something like Monster Screen Cleaner then let it dry overnight or blow it out with the "canned air" then let it airdry for at least 4 hours before plugging it back into the computer.
