A ratchet and pawl could be used in this manner with the added advantage of being designed to engage even if the ratchet teeth don't line up with the pawl when the lock is activated.
As a note, With this system, it might be necessary to drive the lift up a bit to get the rachet to disengage. It is advisable that the program automatically does this to avoid damaging the servo.
