Answer:
have been locking ( present perfect continuous)
had been locking ( past perfect continuous)
will have been locking ( future perfect continuous)
Explanation:
The present perfect continuous tense (also known as the present perfect progressive tense) shows that something started in the past and is continuing at the present time. The present perfect continuous is formed using the construction has/have been + the present participle (root + -ing).
We use the present perfect continuous to show that something started in the past and has continued up until now. "For five minutes," "for two weeks," and "since Tuesday" are all durations which can be used with the present perfect continuous. Examples: They have been talking for the last hour.
