Video Transcript for Thule One-Key System Lock Cylinders Review

Hey guys. Today we're going to be taking a look at the Thule one key system locking cylinders. These are going to replace your factory plastic locking cylinders on your Thule products. They're going to be an upgrade. They're going to add security and prevent anyone from removing or tampering with your gear. Now you can pick these up in quantities of two, four, six or eight.

Really as many as you need to add more security to your accessories. They're very easy to install. What's great about this is we don't need to remove our accessories or our bikes or whatever to get these installed. We can keep it all in place. I'll go ahead and show you how to do that.The first thing we'll need to do is remove those plastic locking cores.

So I'm gonna unlock mine here. Then we can take off the whole cover and we're going to bring it down to our table so it's easier for you to see. Now to get it out of there, pretty simple, just push it out and then we can move on to grabbing our actual locking core. Now, in order for this to work out you'll need to have your master key. So go ahead and push that in.

You can see how that's going to allow some of the portrusions to come out there. You can see how the whole thing has that tumbler design with a master key in place. It's gonna allow us to insert it into the open cylinder here.Now we need to do this a certain way. You can see where those portrusions are sticking out. We'll need to line it up with the open slot right here to your right.

So it's going to push it all the way in until it stops. Then we can remove it and you can see with it in place, we're not going to be able to easily push it out like the plastic locks. So just goes to show you that no one is going to be able to tamper with it with the design that way.From there it's very simple. We just replace it and then lock it with one of our new keys. So we'll go back up top, put it in place, make sure it's all the way on, lock it up, and then we're all set. And then we just repeat the same process with our other accessories. Let's go ahead and do the bike rack next. So as I said, no need to remove the bike or the bike rack. Just going to align it up with the master key. Push it in place, make sure I've got it all the way in then to make sure it doesn't pull out I'll hold it in place my finger, pull out the master key. Bring in my new key and lock it up. And that's going to prevent anyone from removing our bike.So now just like I said in the title, one key system, we have our evo clamps and our bike rack keyed to the same key. Now we're not carrying around a bunch of keys so we can use one key to access all of our accessories. This is a huge plus. Now when it comes to removing your existing locking cores, the way we do that is you'll want to unlock them. Go ahead and take that cover back off. Come back down to our table here so we can see. Then you can use that same master key, push it in there and then push out.So what I'm saying is if you already have locking cores but you want to replace it with the one key system, you can use that same master key to push that lock out and replace it with a one key system. So again, a very simple design. Pick up as many locking cores as you'd like for all of your accessories. And again, that way you're only carrying around one key. Now the system does include two keys, so you can store maybe one in your glove box, one on your key ring, and you don't have to worry about losing anything.The keys themselves are fairly large, so they're going to be easy to operate. You're not gonna have any issues locking or unlocking your accessories. Now they also have a unique design with a textured grip. This is a step up compared to your older generic style can use that all look the same. You're not going to have any problem identifying these keys. They also have a large slot, so you can easily attach a key ring.Now let's take a closer look at the actual tumbler. One thing I'd really like to say is they really are tamper resistant. Thule makes them extra thick with long protrusions, that way they can't be accessed with a screwdriver or a similar device. Again, very heavy duty. We don't need to worry about anybody accessing these with anything but the keys. But with that being said, that's going to complete our look at the Thule one key system lock cylinders. Again, you can pick these up in either two, four, six, eight quantities, really, however many you need for your Thule accessories.

We just purchased a 2019 Hyundai Santa Fe as our retirement vehicle for traveling. We wanted to install cargo accessories but the dealer prices were WAY to high. After researching for several days we found etrailer.com. The prices were the best we found and the service was outstanding! We installed a Thule roof rack system that fits flawlessly and allows the panorama sun roof to plenty of roof to operate. The videos made in really easy to install. We also installed a trailer hitch system. The Tekonsha Trailer Wiring kit was also a piece of cake to install. If you're hesitant to work on electrical systems, there's no need to be afraid. It's actually easier than it looks in the video. The Curt Trailer Hitch gave me major headaches. The delivery company banged the box up pretty badly. Apparently it tweaked the hitch just enough so that the holes were misaligned. No problem, after talking me through the installation one more time to be sure it was damaged, they shipped a new unit. The second hitch went in fine. It took a while, and it's not as easy as it looks in the video, but I'm 67 years old I did the installation myself... Overall, I gave five stars because the price match guaranty makes it a wise choice price wise. he videos are a big help during installation. But the real difference is the service. A lot of folks provide good service to make a sale, but etrailer goes the extra distance to provide great service afterwards. That's unique! Thanks etrailer! 707578

I ordered the Aeroblades, adapter kit and a set of locks cylinders for my 2016 Suburban. The guys at etrailer were great to deal with. They got my shipment out the door quickly and was delivered in time to install the next weekend. Fits perfect and looks factory fit. All parts were accurate and delivered in great shape. Always great service and great prices. Thanks! 456395
