Mighty Mule FM134 / Linear RB742 Two Button Gate Remote - 4 Pack
The Mighty Mule FM134 / Linear RB742 Two Button Gate Remote - 4 Pack is a bulk pack of two button keychain-style transmitters for compatible Mighty Mule, GTO/PRO, and Linear Pro access systems. This pack is useful when a property needs several users to control more than one access point, or when the installer wants a compact remote that can handle two receiver channels from a single transmitter. Compared with a one button remote, the FM134 / RB742 style gives the user more flexibility without moving to a larger multi-button transmitter.
Common applications include residential driveway gates with two separate entrances, a gate operator plus a compatible auxiliary receiver, or a gate and garage door setup when the garage side is equipped with the correct receiver. This transmitter family is frequently associated with Mighty Mule and GTO/PRO radio systems and is often searched alongside FM135, RB741, and RB743 style remotes.
Because two button remotes depend on the installed receiver and channel wiring, compatibility should be checked carefully before ordering a multi-pack. The operator model alone may not tell the whole story, especially if the site has an external receiver, upgraded radio equipment, or mixed older and newer gate controls. Confirm the existing working transmitter, receiver label, frequency, and intended second button function before distributing remotes to users.
Compatible With
Mighty Mule and GTO/PRO gate openers using the FM134/RB742 transmitter family; commonly associated with Mighty Mule, GTO/PRO, and Linear Pro residential gate operators using compatible 318 MHz radio controls; may be used alongside FM135, RB741, and RB743 transmitter families where the receiver supports them. The second button can be used for a second compatible gate, separate receiver channel, or gate/garage setup when paired with a compatible universal receiver such as RB709U-NB. Verify the receiver, channel setup, and existing remote before ordering.

Technician Note
When programming two button transmitters, label which button controls which gate or receiver channel before handing remotes to customers. This avoids confusion on dual-gate properties and helps diagnose whether a programming issue is related to the remote, receiver channel, or operator input.
Before Ordering Checklist
- Confirm the site uses the FM134/RB742 compatible transmitter family.
- Verify the receiver frequency and whether it uses one or two channels.
- Check whether the second button will control another gate, a garage receiver, or an accessory input.
- Confirm transmitter memory is not full on the receiver or control board.
- Compare the existing working remote model before buying a bulk pack.
Professional Advisory
Remote programming should not be used to work around a faulty control board, damaged receiver wiring, or missing safety devices. If the operator is moving unpredictably or not stopping properly, have the gate system inspected before adding more transmitters.
Product Questions and Answers
What is included in this RB742-4 listing?
This listing is for a 4-pack of FM134 / RB742 style two button transmitters for compatible Mighty Mule, GTO/PRO, and Linear Pro gate systems.
Why choose the two button FM134/RB742 instead of the one button FM135/RB741?
The two button model is useful when the site needs control of two compatible channels, such as two gates, a gate and an accessory receiver, or separate entry points.
Can the second button operate a garage door?
Only if the garage door opener is connected to a compatible receiver, such as an appropriate universal receiver setup. It is not automatically compatible with every garage opener.
Does this remote work with FM135 and RB741 systems?
FM134/RB742 is commonly listed in the same compatible Mighty Mule, GTO/PRO, and Linear Pro remote family as FM135/RB741, but the receiver and programming method should still be checked.
What causes a new RB742 remote not to program?
Common causes include an incompatible receiver, full transmitter memory, weak remote battery, incorrect channel selection, or an older gate system that has been changed to a different radio receiver.
