Comparison of Genie GM3T-BX and GM3T-R garage door remotes

Height and weight

Genie GM3T-BX vs. GM3T-R

Engineering GM3T-BX

These remotes are quite small, avoiding the bulky and clunky design of most remotes on the market today. However, the GM3T-BX is slightly bigger and taller than the GM3T-R. Despite the slight difference in size, the two remotes still weigh the same.

Parent model

As you might have guessed from their very similar names, these products have the same parent model: the GM3T remote. This primary remote has some very interesting features that make it universal in use regardless of the type of door opener or community receiver owned. As can be seen in the following sections, the Genie GM3T-BX and GM3T-R embody these universal characteristics of their parent model.

Compatibility with receivers and openers

These remotes are capable of working with all gated community receivers manufactured by Genie. They can also operate almost all Genie garage door openers manufactured after 1988.

These remotes are quite versatile, being able to work with older door opener units having 9 or 12 switch receivers, as well as newer door openers designed with Intellicode 1 or 2 receivers.

Compatibility with dual frequency models

If you have an opener with the 390/315 MHz dual frequency auto search function, the Genie GM3T-BX and GM3T-R can still be purchased as they are designed to be compatible with these models of opener . This is because the remote controls use dual frequencies 315 MHz and 390 MHz to ensure minimum interference during operation.

3 button function

Both remotes are designed with only 3 buttons. These buttons are large, made of rubber, and take up almost the entire surface of the device. This ensures that anyone can easily and easily access the buttons for activation and optimal use. When programmed, these buttons can act for separate transmission purposes.

However, very few customers were not entirely happy with the buttons, claiming that they did not make an audible click when pressed. This usually ends up leaving new users in doubt as to whether the buttons were properly pressed or not.


Since these remotes are meant to be universal, their programming steps differ depending on the type or model of Genie opener you want to pair them with. It might sound complicated, but it’s actually quite simple. For any model of opener owned, the programming steps are straightforward and easy to follow. It is imperative that the instructions and programming steps written in the accompanying manual be followed exactly to ensure a simple and smooth setup.

With these programming steps, the exact function of each of the 3 buttons can be determined by the user based on their own taste, style and preference.

Included accessories and practical features

Both remote controls come with a sun visor clip, which makes them very convenient to clip onto your car sun visor. These remote controls are powered by CR2032 3v disk type batteries which are included in the product packaging. The downside to these batteries is that they are not standard and as such not as powerful as other batteries. They usually don’t last very long, with an average lifespan of just 10 hours. This means that they need to be replaced frequently. The batteries are cheap and small, however, and can easily fit into these small remotes.

On a positive note, these remotes are designed to control a maximum of 3 Genie doors at the same time. They are also equipped with useful LED lights. They can also be used as aftermarket remotes in case you still want to use the original remote that came with your opener without fear of interference between the two remotes.

Rolling code security technology has been implemented in the design of these remote units. This security feature ensures that the entry code used to access the doors is changed each time the remote controls are used. This works to prevent the hijacking of security codes by eavesdroppers, hackers and thieves, preventing unwanted entry into the garage and providing maximum security and safety.


Engineering GM3T-R

A lot of users have complained about the limited range of these remotes. Remote controls can only open your garage door if you are within close range of the door in question. Basically the remotes won’t work if you’re a few blocks from your garage or just heading to your driveway. However, they would do just fine if you are at the end of your driveway.


Both products come with a one-year limited warranty.

The inconvenients

Both remotes are universal, can work for almost any Genie opener. There is hardly any difference in their functions. The only difference is in the size and the price. The GM3T-BX is a bit bigger than the GM3T-R and therefore cannot be easily misplaced. On the other hand, at regular price, the GM3T-R costs a few dollars more than the GM3T-BX. However, research has proven that a sale could change that and the GM3T-R could end up costing even less than the GM3T-BX. My advice is to go for the cheaper model when you buy it.
