CHAMBERLAINClicker Keyless Entry KLIK2U-P2, Works with Chamberlain, LiftMaster, Craftsman, Genie and More, Security +2.0 Compatible Garage Door Opener Keypad, White

I had an old, 30-year old Genie garage door opener that used DIP switches to set the security code, with a very old KLIK2 (no suffixes) that worked with it; I absolutely loved the keypad, and wish I could have kept it. But when I replaced the garage door opener this week with a new Genie 3155D unit this week, I could not for the life of me reprogram the old KLIK2. So I ordered a new one, hoping that it would support the newer garage door openers and technology. I took the new KLIK2U-P2 out of the box, promptly went to the garage, followed the instructions given, and on the first attempt of programming it, the garage door was going up and down as expected!!!!Although I have only had it for a day so far, I'm back to loving this unit. This unit uses four (4) digits for the code, which is sufficient for my needs. The Genie keypad defaults to 3 digits, but can go up to 8 digits. But as I was replacing an earlier version of this device, I did not have to drill any new holes into the wood by the garage door.That said, I also hope this lasts as long as the previous unit; again, I had nothing against the previous unit, other than I could not program it for the new garage door opener. Time will tell if the build quality is as good, if not better. I will update this review if anything changes. (Don't hold your breath.)

Why did you pick this product vs others?:Easy to install and set up as a wireless opener. Compatible with new and old openers installed in the garage.

I bought this to replace the one I broke the other day. Up until I broke the original one this opener was fantastic. I recommend.

Easy to install and works like a charm. I'd have called it easy to program and given it 5 stars, but:To "pair" the remote with the opener, you have to identify the latter. I have a Chamberlain opener and there are apparently 3 generations of these. You must identify which one is running your door, and the included instructions (which are quite clear) say to identify its generation by noting the color of the "learn" button. In my case that didn't work; my unit's learn button is orange, which should mean it's a generation 2 machine. In fact it's a gen. 3 and failed to work until I disregarded the instructions and entered '3' instead of '2' when programming the remote. So: if yours isn't working and you have a Chamberlain opener, try a different number.

Works great with my other systems. Love the universal aspect.

I just installed this unit today - so this review is based on installation and compatibility, not long term performance. I am definitely NOT the tool person in this house, but my partner's honey-do list is too long. So I gave it a try. This keypad is a replacement for my Craftsman, bought in 1998. We have a second garage door with a Genie unit I bought last year. I will get to installation in a minute, but I have to say, this key[pad dependably opens the door every time (well, at least the first 10 times or so!), unlike my Genie, which is very hit or miss. I am pleased and surprised that this seems to work so reliably.I was nervous, having red the reviews, about installing the unit. I decided to program the remote before mounting, partly because we had bought another brand's universal remote and it worked fine. Also, it is a two person job if you mount the unit before pairing. The first thing I did was find my opener's "learn" button - not so easy, as it was hiding behind the lightbulb. That was the hardest part. I have a red button. I followed the instructions carefully. I did not add an "0" before pressing 2, to indicate I have the red learn button. I followed each step promptly, but not rushing. I would estimate I held buttons down for a full second, maybe 2 seconds for the learn button, and immediately proceeded to the next step. And guess what? It worked on the first try! The programming took 5 minutes at most. EASY PEASY.Some people have had difficulty with the cover - me too. I had to force it open with a screwdriver, having hand issues. So I took one reviewer's advice and modified the cover slightly. Here's how: Slide the cover off. Inside you will see two lines of plastic on each side that stick out. The short line of plastic is on the upper end. Look at the long line. Take a very sharp knife (like a box cutter or utility knife) and shave some off to taper the top of the long line of plastic (the end nearest to the short piece). Do this on both sides and the cover easily slides up.Don't be intimidated by the programming, follow the simple directions closely - you can do this.We were considering replacing the entire garage door opener. We had bought a Genie universal replacement keypad first, and that didn't sync up with this opener, so we thought we were up a creek. I am very happy that we decided to make this purchase.
