"E" key doesn't work on PowerBook

Hi! I've tried cleaning the contacts (only by removing the key cover) with Caig DeOxit several times but to no avail. Is this a dirty contact that must be cleaned by full disassembly? Any ideas? Thank you very much!

Hi! When the key cover is off, and you press down on the bouncy piece in the center of the key, does that work? If so, it's a mechanical issue that may require you replace the plastic scissor contraption under the cover (you can get these and keys themselves on eBay for a few dollars), and if not, likely an electrical trace on the keyboard has been crimped/cut/etc., and you'll need a new keyboard.

Thanks! Alas, the key does not work with the cover off, or even if I press directly on the contact with a probe. It sounds like I need a new keyboard. Glad there are parts and instructions here in order to do the job, even if keyboards are a little pricey. Thanks for your help!
