Perfect replacement for broken remote controlAre we Friends huh? Trying to help each other out by these reviews? That is good, but who we are affects how each of us perceive things. If you want to know who I am you could go to, under books, A Path Less Taken, the true-life adventures of One Man. You will see I am still running a ranch and my driveway is over three miles long and has two security gates on it. I have three side by side Rangers, two pickups, three tractors and a family outfit and each one has one of these remotes in it. Pros- They work well and I love them. Cons- The batteries only last a year or so and they are hard to change. When changing batteries you can easily hit one of the keys and may have to reset it.Openers were purchased for our HOA. These are easy to program and moving the set switches takes a little effort. This should help with the accidental movement of the set switches while replacing the battery.So, I was about to send these back because they didn’t work. We programmed them with the correct code and nothing happened, they just didn’t work. As I was getting ready to package them back up, my husband decided to play with them and tried again. He messed with them for a couple of minutes and then boom, it worked! What he did was moved the switches to opposite of what the code should be. So if the peg was supposed to be up, he put it down on the new ones. For some reason, the switch board is upside down/backwards on the ones we received. Hopefully this helps anyone who receives them and can’t get them to work.I did only give 4 stars because the ones we did receive were a little faulty on where the clip snap in. It looks like the plastic isn’t cut properly so the clip doesn’t slide into its slot. We had to cut a little part out in order to get it to slide into place.Buen precioIt sometimes needs to press multiple times to work with the garage. But for this price I think it's ok.This unit is a replacement for the original transmitter that came with my electric gate. It is identical. The code is locatedinside the original unit, they are little flip down rocker switches similar to wall switches with numbers on them. Use apencil or anything with a small point to flip the little switch. Be sure to write down the number from the original switchlocated on the inside switch tabs. You may have to use something to magnify the number if you wear glasses. Transferthese number to the new hand transmitter box. Some of the new 9 Volt batteries will not fit properly. The unit comes witha battery, write down the name of of it for a replacement with it comes time to buy a new one. Did not give it 5 stars, its made of plastic and does not go to gather well. This part of it is cheep. When you are installing the code, don't play with the button,it will activate what ever your controlling, in my case, a 10 foot security gate side entrance with three large HUSKIES in side.It open the gate from inside the home, good thing my dogs did not see the gate open, they would still be gone. When I pushed the button, I wondered it it actually open the gate, I checked, and you know what, it did! It works very well.Worked right out of the package. No codes to set it anything. Very satisfied with purchase!! 5 stars
