Choose your opener brand, enter its model if you know it, then select the LEARN-button family or named technology. The result will say exactly what the evidence supports.

How to use the result
Start with the model label attached to the opener, not the old remote. A family-level listing does not rule out model revisions. If you cannot identify the system, follow the official manual link rather than guessing from an RF number.
Private by design
This tool runs in your browser. Do not enter a keypad PIN, DIP switch positions, address, serial number or garage access code. We do not need them to classify a protocol family.
