A direct measurement of the top-quark decay width using full Run 2 dataset will be presented. The measurement exploits both lepton+jets and dilepton decays of the $t\bar{t}$ pairs. A modified version of a profile likelihood technique has been developed to incorporate multiple templates to extract the decay width. The modification as well as various cross-checks that have been done to validate the technique will be presented.
