It cannot clone rolling-code, two-way, or encrypted single-chip remotes such as those using HCS200, HCS300, or HCS301 chips.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I know if the code has been successfully copied?\u003c\/h4\u003e\n\u003cp\u003eA: After pressing the matching buttons on both remotes simultaneously, the LED indicator on the duplicator will flash twice quickly and then remain on — this confirms a successful copy.

This overwrites failed copies while retaining the successful ones.
