Increasing the lock on a gauge means increasing the level of security associated with it. This can be done by allocating a portion of the gauge to a previously voted-on measure. This measure could include adding additional locks, or increasing the number of locks that need to be opened in order to access the gauge. By increasing the lock, it makes it more difficult for someone to access the gauge without authorization. This increased security can help to protect the gauge from unauthorized access and potential tampering.
