Which specific games are problematic? Make sure you use unscrubbed isos and a good brand DVD-R media (Verbatim is recommended) in order to rule out as many causes as possible.
Also, which version of the Wii System Menu do you have (3.4u, 4.0u, 4.1u etc.)? And do you have any softmods installed?
The nature of the problem you are experiencing points towards a hardware issue, so if I were you I would check the DriveKey installation again (make sure the chip sits as it should and is insulated correctly with the sticker - and that all cables are connected correctly).
