Unable to reset the Sensative strip guard after multiple attempts

We have the Sensative strips Guards (MS-H).

Every time we try to reset it using the procedure mentioned in the following video, we always ending doing so many attempts before it gets reset properly. But with other sensors we didn't face this kind of issues, could you please point us what could have been gone wrong?
