Mighty Mule FM135 / RB741 Single Button 318 MHz Gate Opener Remote - 2 Pack
The Mighty Mule FM135 / RB741 remote is a single-button 318 MHz transmitter used with compatible Mighty Mule, GTO, and Linear Pro gate operator receivers. This 2 pack is commonly ordered for adding users, replacing lost remotes, or keeping extra transmitters for family members, employees, tenants, or service vehicles. The remote must match the receiver technology on the gate system. It is typically associated with the 318 MHz dip-switch / narrow-band Mighty Mule and GTO radio family, not with unrelated LiftMaster, Genie, or newer non-compatible rolling-code systems.
This item is commonly used when servicing older GTO, Linear Pro, and Mighty Mule gate operator systems where the original part number, radio generation, or bracket style needs to be matched before ordering. Because these product families have been sold under multiple brand names over the years, the part number on the operator, receiver, transmitter, or parts diagram is the best way to confirm the correct replacement.

Technician Notes
Before ordering multiple remotes, confirm the receiver on the gate is the correct 318 MHz Mighty Mule / GTO / Linear Pro receiver. A remote that looks similar may not program if the frequency or coding style does not match.
Before Ordering
- Verify the existing working remote says FM135, RB741, or a compatible model.
- Confirm the receiver is a compatible 318 MHz Mighty Mule / GTO / Linear Pro receiver.
- Match dip-switch settings or follow the receiver learning procedure as required.
- Replace weak transmitter batteries before condemning the receiver.
- Do not order this remote for LiftMaster Security+ or Genie Intellicode systems unless an external compatible receiver is being used.
Professional Advisory
Gate hardware, radio controls, and receiver wiring should be installed so the operator continues to meet the required safety setup for the gate. Do not bypass photo eyes, edges, entrapment protection, or other required safety devices to make a repair work. If the gate has damaged brackets, excessive binding, incorrect limits, or unsafe wiring, have the system checked by a qualified gate technician before returning it to service.
Questions & Answers
Is FM135 the same remote family as RB741?
Yes. FM135 and RB741 are commonly referenced together for the single-button Mighty Mule / GTO 318 MHz remote family.
Will this remote work with my garage door opener?
Only if the garage opener has a compatible external receiver such as the RB709U-NB or another matching 318 MHz receiver. It does not directly program to most unrelated garage opener brands.
Why buy a multi-pack?
Multi-packs are useful when adding several users at one property, but all remotes still need to be programmed or set to match the receiver.
