NEVER use WD40, CRC or anything similar in any lock, only ever use graphite powder in locks! (Just ask a locksmith)
What I have done to stop dust in the lock, is to stick a piece of about 6mm black foam sealing tape on the bottom of the lock across the keyhole, then with a razor craft knife I cut a slit in the tape in line with the keyhole.
Since doing that I have never had a problem with the lock.
