Chamberlain Group G7702CB-P Chamberlain 7702CB Quick Release Lock garage door opener part(Package May Vary), Silver, 2.25 x 1.13 x 1.31 inches

I'm not really sure what to say other than this product worked and looked just like what it replaced. I see people are mentioning the design of the keys. I don't recall whether the keys were made of copper or zinc plated or how the keys were designed/cut. I can't say that it really matters to me, because the keys were the same overall size as what it replaced. I repaired a neighbors garage and handed him the keys. I do recall reading about the keys before I bought it and when it arrived I thought I don't understand the fuss. It's a key like any other key. The home was foreclosed on during the Great Recession and the bank literally took a drill to the previous lock, then damaged the property by attaching a latch and padlock. The previous owner had cancer and was going through hard times as a result of it. I wish I could have helped her or that there was help for people going through such trouble. At that time there wasn't help from the government. However, I'm very happy to have helped the new owner. This kit was very easy to install. My only wish is that the carriage bolts were made of stainless steel rather than zinc plated iron, but you can always upgrade that at your local improvement store.

I'm a 62-year-old retired woman, and it took me about 25 minutes to install this quick release lock! I had the holes already in the door from my old lock, so that made it easy. The most time-consuming thing was removing the OLD lock's S hook from the garage door lever (had to use 2 sets of pliers to twist the S). One small glitch with the new lock was the very long set of mounting bolts which I couldn't install because of the way my garage door is constructed. I rifled through my tool box and found 2 shorter bolts (with washers and nuts) that did the job.It helps to have 2 people, one outside the garage to push the lock mechanism through the hole, and another inside to pull it through. In my case, it was a necessity, because there is only one way into my garage.I found that the cable was more than long enough. People who say it's too short have probably mounted the lock mechanism too low on the garage door.I'm very pleased with the quick release lock. It's well-made and works easily. I was happy to see that they included two keys. They even give their mailing address and info about ordering extra key blanks.

I needed a manual override for my external car garage, which doesn't have an alternate way to get in. Rather than carving out a silly door, I decided to buy this product which would allow me access to in case of a power outage (so I can retrieve my badass portable generator to continue enjoying all my fancy electronic gadgets and air conditioning, while my neighbors envy me as they melt away in sweltering Texas heat. wondering why they didn't make such a wise decision - oh, and I think it would be good to have access to the cars as well).Now that I've shared information which was nothing but wastage of your time, here's some that may help you make an informed decision.Level of Expertise: If you can work a drill, you qualify.Level of Difficulty: 2 (1 = Easy, 10 = Difficult)Time for installation: 30 minutes for metal door, 20 for wooden doorTools needed for installation (in order of steps):1) Pen/Pencil to mark holes to drill using the provided stencil2) Drill with appropriate Drill bits (Don't forget those safety goggles)3) Pliers or wrench, to tighten the nut4) Ladder (optional), to allow ease of access to the (garage door) trolley5) Pliers (optional), to make installation of trolley attachment easierPros (in order of significance):1) Secure Mechanism. There are 2 factors that make this up: (1) Metal cable (to avoid breakage), and (2) Mechanism that attaches cable directly to the trolley vs the existing rope; this ensures you have a secure pull every single time,. This mechanism is quite impressive - not only does it allow for this manual override but it also has dedicated slots for securing both the metal cable as well as the existing rope.2) Easy and Quick installation (I installed it on a metal door, and drilling took the most time)3) Inexpensive ($10 something from Amazon, not 3rd party sellers). Based on other reviews, I'm guessing some 3rd party sellers are selling knockoffs for a couple dollars cheaper, so I stuck with Amazon (as the seller).Cons:1) The lock looks like it's easy to pick. I personally am not too worried about it but it may be area of concern for some

My garage doors needed a longer bolt. You can get a 2.5 inch carriage bolt (10-24 if I recall) and that worked. The instructions say to attach to the central rib. I spent time with a dremel grinding the hole larger. The actual lock body only goes halfway thru the door, so you don't need to do that. The cable would go thru the smaller hole.

I'm a new home owner and the previous owners of the house couldn't find the key to the garage lock and the garage doesn't have another entry. I couldn't find the lock at the local hardware and didn't want to pay a locksmith fee to rekey it. So I YouTubed how to replace it and bought this lock. It was simple to install even for me, only took a few minutes after I got the old lock out. All the parts were included, were sturdy and about the same grade as the old lock that had been installed many years ago. I've only used it once and it performed great. Definitely happy I bought this lock.

This is a quality product, Chamberlain-branded product and I was able to replace my old emergency release lock using the same holes. Installation took 15' and it worked fine. What I received looked a lot nicer than the picture. It was packaged in a branded box with instructions. One key feature of this product is the cord length. It is 6 feet long. Other products come with 3' cords and, at least in my case, it would have been extremely tight. This was the reason why I ordered it and I am very glad I did.
