Try some Deoxit D5

You can try spraying it with some Deoxit contact cleaner and move the key around in the tumbler. Being naturally lazy, I'd try this before taking the electronic switch apart. This stuff works well on vintage stereo switches and potentiometers to clean and lubricate the contacts. Then let it air dry - while you have it out, you can hook up a multimeter and check it.
