Yes but it takes less than 10 seconds to reprogram it after you program the new one.my remote work perfectly. .

You will need to reprogram originals at same time of new set.instructions will explain.

I don't believe so. I have to change one manually when I turn on a second source.

Only if it previously pre-wired for one, like if you are replacing an existing one.

Yes like the others have stated below, when you program the replacement remote just do the same thing with each remote you want to add.

If it's the same, then yes. All you have to do is program it. Follow the instructions.

Two fobs.If you have them (fobs) it is very easy to program a new one. If not, you will need to go to a dealer (or locksmith) and have your fobs reprogramed. I was fortunate. One of my fobs was broke but I could still get it to work. Hope you do too.

They come with batteries ready to use and you will have to program the new ones as well as any you presently have will require reprogramming at the same time. I had two original and two new ones and it only took a few minutes to program all four together. Any that you don't program, either old or new will not work any more.

You have to reprogram it after it has been disconnected from the battery. BTW, I have two of these units and they work quite well.

No, reprogramming is not needed. The entire internal transmitter assembly is transferred to the new case, not just a single chip. A very simple change, shouldn't take more than a minute or so. Works great, but the bottons on the new case are a lot harder to press, takes some getting used to.

Yes, but you will have to program it to motor. Your other one may just need to be reprogrammed also. You may want to contact Somfy and have them troubleshoot with you.

Programming the new one doesn't affect the old one. Why do you need two? Did the old one stop working?

I did not have to reprogram when I changed the batteries. Only changed them once so far, so...

This item is just a replacement case, in other words, it is just the exterior shell of your remote opener. You have to move the interior electronics from inside your old case to this new case to make a new working remote. Moving the electronics is simple to do. Since you are using your current electronics, there is no reprogramming necessary. See elsewhere on this listing for more info if needed.

Yes if you misplace ii or it is lost, need to get second one before that happens, and the other one will be easier to program off the main. It will save you time and money in the future.

Also as stated in someone else answer you need 2 that is not true. They only needed one key to program after it was cut.
