a downhole tool operable to perform downhole operations to retrieve a used gas lift valve installed within a gas lift mandrel connected along a wellbore tubular string and install a new gas lift valve within the gas lift mandrel, wherein the downhole tool comprises:
a housing;
a first holder configured to hold the used gas lift valve;
a first displacement mechanism operable to move the first holder between a retracted first holder position in which the first holder is adjacent the housing and an extended first holder position in which the first holder is spaced away from the housing;
a second holder configured to hold the new gas lift valve;
a second displacement mechanism operable to move the second holder between a retracted second holder position in which the second holder is adjacent the housing and an extended second holder position in which the second holder is spaced away from the housing; and
an interlock mechanism operable to permit the second displacement mechanism to move the second holder from the retracted second holder position to the extended second holder position when the first holder is in the retracted first holder position and holds the used gas lift valve.
