Do I need one or two of these for a two car garage?

I would believe you would need two of them. It is a single laser, so if you wanted one for each vehicle, you would need two.

One only... Unless you have a MULTI ZONE outdoor unit, than you need one for each zone.

You will need one for each vehicle as they register the Vin of the vehicle you apply it to and won't allow another until you set it back to factory, or you can pay them a fee to add a second vehicle to the programmer... I believe. I think it's a hundred dollars to add a second but I'm not sure

I would get 2 units. Even if one does the job, this is such a wonderful product that you are sure to find another place where you want to put one.

The short answer is maybe. You do need one per garage door opener unit. I suppose, in theory, you could wire a single receiver in to multiple openers units, but then you're locked into (if there are two) them both opening and closing at the same time.

If it works fine with one than probably no concerns. I have noticed I can run it with one as well and odds are using two is mostly for extra power.

No, you only need one. Please check out this video for more detail. https://www.youtube.com/watch?v=0Fs6v3rvuuk

I cannot answer that by experience, but I don't see why not as long as you have the appropriate electrical wiring. I would rely on your electrician to determine if two units are too much for one wiring unit.

You wont need one if you have a technician come out....otherwise....you only need one.

I did not need two but I see no reason why you can't. They do not stop the banging 100% but greatly reduces it.

you will need 2 of them, one for each. Best is to install at the back the base ( motor). Let me know if you have any more questions and good luck.

They are sold as single units so if you need two you will need to have to order 2 of them.

If you have one garage door motor then you will only need one Garage Butler. If you have two wall buttons and two garage door motors then you will need two Garage ButlersBill Support@garagebutler.com

You will need 2 of them, and a direct line of sight. They are very easy to install however. Just go on YouTube an they have tutorials

Probably just need 2. We have 1 in a 20×20 patio and it is VERY powerful at full speed.

You would only need that if you had only 1 outlet available. But if you're able to use 2 then you don't need it
