Locations of Keycards
The blue one was located in the main misson in the gadgetbot misson inside the A-EYE. After the cart part where you used the ladder to overcharge 2 locks, you had to then get back on the cart and go backwards. You eventually saw the keycard somewhere.
Red was found on the Asyanica rooftops. At the second line of police cars, on maybe the second one there was a little ledge, if you pressed select and looked down you saw it. Jumping off will result in death, but you eventually got the keycard.
Yellow was found in the Saint Qwark level. You had to get to the part where you saved the nuns by hitting the cannon to release them, but this time, you were not meant to hit the cannon. Instead you had to go to the place where you saw the space, Kudzu eye, from afar. Then near the edge you had to walk off. You then had to use jetpack to hit it in midair. You were not meant to jump off, but instead had to walk off. If you missed it, you just had to go back and try again.
