Described herein are example fluid guards that can be used with locking devices. Various aspects may be particularly applicable to electrical locks, but they may also be applicable to mechanical locks. A locking device guard can include a guard cover, a fluid absorber, and a coupling element. The fluid absorber can be configured in a closed configuration to fit at least partially within a cup of a lock face. The coupling element can be configured to couple the guard cover to the lock and can define a second axis.
