When I first purchased my new bike in 2020 it made all sorts of little rattles over bumps which drove me nuts (I like my vehicles rattle and noise free - other than the stereo). It took me a couple of weeks to locate and neutralize the rattles and what a difference! Then I decide to put new Look carbon Keo pedals on it and another bike. Whenever I was putting the power down on climbs or out of the saddle they would creak like SOBs. I took off the cleats and waxed the interface to the shoes. I took the brand new pedals apart and relubed them and then I waxed the interface between the cleats and the pedals which was a temporary fix. After researching on the net creaking noises were very common with Keos with no permanent fixes - (a few people never had creaks, which I did experience when just moving along without smashing then pedals.), plus they were a PITA to clip into until I shimmed the front-most screws. Getting fed up, I purchased Shimano pedals and have lived a happily creak-free ever after.
