Exactly what I needed to rekey two bike racks (since they don't come with your rack, thanks Thule).


Easy installation, Fast delivery, in stock, master key & 2 Product keys, [online] videos are excellent,great way to protect my Thule system investment


always the best and fastest service. and the videos are always a biiiiig help.


Despite the pandemic going on Etrailer was following up on mu order , It took awhile for order to come in ,but etrailer staff constantly updated me on my purchase and provided solutions will definitely go with etrailer again for future purchases


The one-key system worked great


I don’t usually write reviews, but I felt particularly compelled to write one on this purchase. etrailer shipped my items quickly and had fair prices for the rack I wanted for my car. The packages arrived in two boxes. The items were floating freely- literally screws, wrenches, bars, instruction manuals etc were just thrown into the 2 boxes. It was a mess. I needed to check under the folded cardboard in the base of the box to find some of the pieces, which had settled under there. Not surprisingly, I was missing 3 screws and 1 plastic lock in the order. I needed to drive to [hardware store] mid assembly to get a screw match. Fortunately, I had ordered replacement metal locks anyway, so that wasn’t a big deal. In the end, I got the rack assembled, but it was a mess and I gotta say, that was the packaging you would expect from an amateur [resell site] order.

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 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!


Nice looking rack, easy to install, but oddly doesn't use the rail on the car. The rack base sits on top of the rack and a bolt that holds the rail on the Jeep roof is removed and replaced by a bolt holding the rack base to the car roof. One wonders what the rail is for. Unfortunately, the first time I used the rack to transport an extension ladder, one of the rack base covers that was locked in place was gone when I got to my destination (see photo).


8 Locks, 2 keys, and a a master key tool in a compact cardboard box. Half the locks installed on my roof rack, and the other half on the trailer hitch bike rack.


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!


Uber quiet, great fit, very happy!


Game changer to go from 8 different keys to one!!


The lock cylinders and keys were easy to install and are easy to use.


Locks work great. Appreciate working with the knowledgeable experts at etrailer to make sure everything I order works together.


Rails look great on the car, car carrier is amazing. Shipping was fast once the items were in stock, and delivery was perfect. The reviews and how-to videos on the site were invaluable.


Worked perfectly and all my Thule products have the same key.


Happy with the purchase, great communication from E trailer. Parts arrived earlier than expected. Love the service.


Love the option to have one key that works in all accessories with rack itself!


Cylinders were simple and intuitive to install.


As expected, 8 lock cores and 2 keys


it was good and worked


Works well, easy to use. Keys sometimes a little finicky to put in.


Mentioned to Carol C. that I had an upcoming trip and my orders arrived before my trip! Bravo! Thanks sells Rep Carol C!


Easy install and even better they do their job. Keeping my rack safe and secure on top of my car.


Exactly what you think it is.
