Multiple controls
3 buttons can be assigned according to the manufacturer’s programming options; compatibility still has to be checked for every opener.
Several generations
The indexed specification spans 1 manufacturer/protocol family: Genie.
Legacy cross-reference
This model is retained to help owners identify an older accessory; do not treat its presence as a current purchase recommendation.
Protocol coverage matrix
This is the useful part of a compatibility claim: the actual radio family, any learn-button cue, how many exact opener records XEKOV can cross-check, and how many current accessories share that protocol.
| Published family | Radio / protocol | Identifier | Indexed opener models | Current accessories in database |
|---|---|---|---|---|
| Genie Intellicode Genie | Intellicode 315/390 MHz | Protocol-based | 8 | 7 |
| Legacy Genie DIP-switch Genie | 9/12 DIP-switch fixed code | Protocol-based | 0 | 0 |

Programming and safety
Use the programming instructions supplied by Genie for this exact accessory. Compatibility does not mean every programming sequence is identical. If a remote used to work and suddenly stopped, first check its battery and the manufacturer troubleshooting steps before erasing opener memory.
If the opener is older than 1993, lacks working photoelectric safety sensors, or has been modified, consult the manufacturer before use. XEKOV does not provide instructions to bypass door safety devices or access controls. Use remotes only with systems you own or are authorized to operate.
Common questions
What openers does the Genie GM3T-R work with?
Its manufacturer-listed protocol coverage on XEKOV includes Intellicode 315/390 MHz, 9/12 DIP-switch fixed code. Use the protocol table and exact opener examples on this page rather than matching by appearance.
Is the GM3T-R a universal remote?
It covers multiple radio generations, but XEKOV would not treat that as unlimited universal compatibility.
Do I need the same number of buttons as my old remote?
No. Button count determines how many doors/functions the accessory can control; it does not by itself determine radio compatibility.
