Customer Service at etrailer is par none, both before the sale and after. I had an unpleasant experience elsewhere buying and installing a roof rack for my old Prius. After a few days of frustrations, I sent it back to that old online store. This time, I contacted etrailer to see what ALL I needed to install a rack on my new 2018 Honda CRV. They sent me the part numbers and a link to purchase. Viola! After they arrived, I had difficulty with one of the parts (at 69 yo my hands are not too strong or flexible) and contacted etrailer. They sent pictures and more thorough instructions on installing the rubber strip. Another VIOLA! I'm so very happy with my total experience at etrailer. Customer Service, truly, is not better any where else I have made online or brick-n-mortar purchases. 642341

The lock mechanism on my Thule Frontier roof box was hard to turn, box is 10-15 years old, replaced the lock mechanism on box and replaced locks on bike rack so they were all keyed the same. Bike rack locks were easy to replace but I had to do a little research on the roof box, the key has to be in the 2 O'clock position to extract. 725940

The Thule lock cylinders installed almost effortlessly, once I realized that the picture directions started with the plain (control) key and then shifted to the key used to lock/unlock the cylinders. A few simple labels would greatly improve the directions. I was pleased to find that the locks fit my Thule Hull-a-Port XT kayak carriers as well as the Aeroblade Edge crossbars I purchased them for. I'd give the locks a 5 if it weren't for the poor instructions and my actual score is more like 4 1/2. 871912

I've always trusted Thule bars. I have an old Xsporter on my truck that works really well and it has held up over time. I needed to get a Thule rack for my Jeep Grand Cherokee and found that etrailer had all the parts I needed specified for my model. That was one of my favorite things about the site. No need to search around for the different parts to attached onto the factory rails. Once I received the rack and components, it was really easy to install. I pretty much watched the etrailer videos before hand. I have the older Hullavator 897XT to haul my kayak in. With the WingBar Evo, I found I needed to get a slightly longer bolt (6-1.00 x 30), which I got from the local Ace hardware store, to attached the Hullavator support bracket to the WingBar. Once I got those bolts set up, I was on the water with the kayak the next day. Talked to the customer service a few times and they are great friendly people. And I can understand what they are saying. 874105

  • Recommended Roof Rack for 2016 Toyota Corolla to Carry a Kayak
    I'm glad we were recommended and we can absolutely set you up with an easy to install and use roof rack and kayak carrier for your 2016 Toyota Corolla sedan. It is also really smart to go with a roof rack because transporting a kayak on a sunroof with foam blocks is pretty risky. The roof rack I recommend for your '16 Corolla consists of: - Thule WingBar Evo Crossbars # TH711420 (Black) OR # TH711400 (Silver) - Evo Clamp Feet for Thule Crossbars # TH710501 - Fit Kit for Thule Evo...

The rack is made up of the following parts: - Thule WingBar Evo Crossbars - Silver # TH711200 or Black # TH711220 - Rapid Podium Feet for Thule Crossbars - Fixed Point # TH460R - Fit Kit for Thule Evo Clamp Roof Rack Feet # TH145151 - Thule One-Key System Lock...

  • Replacement Keys for Thule Lock Cylinders
    You can order just the new keys for your old Thule lock cores by noting the code number on the lock core face. You'll then add that letter/number code, such as N049 for example, to the part THKEY. In this example we then have the complete part # THKEYN049. Keys are sold individually so you might want to order a few spares just in case. The newer lock cores # TH450400 don't have the lock numbers on the outside.

I have attached an installation video for you to check out.

  • How to Remove a Thule Lock Cylinder with Broken Key Stuck Inside
    The only way to remove a Thule lock cylinder like the ones in # TH450400 is by inserting the master key into a cylinder in the unlocked position. However, I have a few tips and tricks to help you remove the broken key to allow for the master key to be used. The first thing is to spray a generous amount of oil lubricant into the key hole. Your key was probably hard to operate before it broke so the lubricant will help the key slide out a bit easier. Next, make sure that the lock is...

  • Recommended Locks For Thule 460 Podium Rack
    For your Podium rack we do not offer a replacement bolt with tamperproof heads. I recommend the Thule One-Key System Lock Cylinders, part # TH450400. This set comes with 4 cylinder locks and keys that unlock all of the cylinders. Cylinder locks can be a deterrent to theft when installed, providing more security, and giving you more peace of mind. I have linked you to a product review video for these locks.

  • Replacement Keys for Thule Pull Top Slide-Out Ski and Snowboard Rack
    Thule uses a One-Key system on all of its locks, letting you use the same key for each lock. This gives you two options. You can search for the key specifically by checking to make sure that the four digit number on the front of the lock above the keyhole is the same, then searching " #THKEYNXXXX " Where XXXX is the number on the tumblers. This will give you a specific key that matches your lock. Or, you can buy a new set of four lock cylinders with a new set of keys with part #...

  • Best Roof Rack Recommendation for a 2009 Honda CR-V
    I would recommend the Thule Aeroblade Edge Roof Rack for your 2009 Honda CR-V that has factory fixed points. The Edge racks are through bars like you said you were interested in where the bar does not extend through the feet of the rack and instead has a low profile factory look. You would need part numbers: # TH7602-TH7602, # THKIT3042, and for locks part # TH450400. For the money you can't beat this rack based on the style you are looking for. The Whispbar Rack you also mentioned...

  • How to Order Replacement Keys for a Thule Roof Rack
    We can't sell Thule products to anyone in Canada, but I can tell you that to get replacement keys for the roof rack you have you will need to get the number stamped on the lock core and with that you will be able to order replacement keys from a Canadian Thule dealer. For example, if your lock core says N142 you would need replacement key part # THKEYN142. Notice that the last 4 digits of the part number are the key number stamped on the lock core.

  • How to Replace Thule Locking Cylinders on a Roof Rack
    When you go to change the lock cylinders on your roof rack to the cylinders of the Thule Locking Cylinders 4 Pack # TH450400 you will insert the included universal change key into an unlocked cylinder that is currently in your roof rack and then remove the cylinder. It may take a little bit of wiggling for the cylinder to work itself loose, but when the change key is inserted into the lock cylinder the cylinder will be free to slide out. Next, you will insert the change key into a cylinder...

  • How Does Plastic Lock Core Cover Remove From Thule Racks
    There is a small gap between the plastic cap and the outer edge of the lock core hole that is just large enough to allow you to insert a small, flat tool such as a flat head screw driver. Once you have the tool inserted, you will pry upward forcing the cap out. Check out the link to a similar question that I attached for you that has a video showing how to remove the plastic cap and insert the lock core.

  • How to Remove Broken Key from Thule Lock Cylinder
    I spoke with my contact at Thule, and she did have a few suggestions for you to try. She said some people have had success retrieving broken keys using a paperclip. Try wiggling the key out using the paperclip along the ridged side of the key. I have had luck in the past using dental picks to work broken keys out of a lock cylinder. If enough of the key stem is protruding from the lock, you could also try grasping the key with needle nosed pliers and removing it that way. If you are...
