Yes, it grants you a chance to acquire a target lock, and it doesn't matter if you don't have the action. In general when a effect tells you to do something like acquire a lock or take a barrel roll or boost action, you don't have to have it on your bar. For example, X-Wings frequently use BB-8 or Flight-Assist Astromech to perform repositions they don't naturally have.

Other normal rules apply, e.g. target has to be in range of the lock. Being granted a boost/roll action has to be valid by all other counts: able to take an action (not stressed), don't overlap obstacles or ships, etc. If an effect specifies "on your action bar" (PTL) etc then that does require you to have the action.

Also worth noting that this card is not having you perform a target lock action. It's simply granting you a lock, which you can do even if you're still stressed. Another reason this is a fantastic card to equip.
