Video Transcript for A Closer Look at the Thule Replacement Lock Cylinder

I'm Matt with etrailer. Today, we're gonna be talking about Thule's replacement lock core. Replacing a lock core is pretty easy to do, and if I had to choose between the key or the lock core, most cases, the lock core's gonna be a little bit easier because the thing with this is a lot of times, these lock cores don't have a number on it depending on when you got yours. So, the newer ones typically don't. Some of the older ones will have it. But if you don't have that number on here or you don't have access to that number, it's gonna be hard to get that matched up to the right key.

So, there's a couple things you can do. If you still have your key, you can just simply look here. Right underneath the handle is gonna give you that number, and then you can find the lock core that matches it. But if you don't have that key and you just need a whole new set, you can actually find a whole new set here on our website. Now, when it comes to installing this, this doesn't take a whole lot.

You do need to make sure you do have a master key. Also, you can find that on our website. The way this works, you'll push that key in here and it will retract the sides and secure it in there. With that in there, now we can lock it down. But there's not a whole lot else to it.

I think these are just gonna be great if you need to replace a lock core or two on your roof rack or any of your other accessories you might have. Now, of course, if you guys have any other questions, let us know here at etrailer. And again, I'm Matt, and thanks for watching.

got my racks all dialed in with this



by:

Thule products are typically solid and I have been a fan. Ordered two key cylinders to match with my equipments for one-key access. One of the cylinder is defected upon received as it would not retain in the hole. Upon closer inspection it is missing a inner tab for retention purpose. (Noticed the empty slot on the barrel in the picture.). I was surprised as this is a product quality escape from Thule. Called etrailer for customer support and was able to arrange for a replacement. I appreciate the good customer support.



by:

Great service the locks slid in and work perfectly.



by:

Now all my bike rack lock match



by:

A perfect fit. If they are not made by Thule, you can't tell the difference. I've used aftermarket lock cores and they always fall out. These are very snug and secure. I already had some locks that used the same key, so I ordered these to avoid having multiple keys.

Now I can securely lock my kayak to my securely attached Thule rack on my Sylvan Sport Go camper / trailer (see picture).

You can't go wrong with etrailer.com . They have what you need for trailers, cargo, as well as other accessories.

Very easy buying a part from etrailer.com Very fast shipping and easy install! I purchased a thule replacement cylinder and now i just use one key for the hitch and bike lock!

Product worked great! Just as expected & fast delivery.

Another great etrailer deal



by:

I wish I would have watched the video prior to ordering. I didn't know I could simply remove the old ones with the universal key. I guess I have a spare now.



by:

Matched my other locks and keys. Security aside, appears more reliable than the plastic plugs. Shipped very fast.



by:

Awesome quality and fast shipping



by:

Always satisfied with the service from etrailer. The products always arrive quickly and they always work.



by:

Quick shipment and excellent quality. These new lock cylinders installed easily and work perfectly ! Thanks.



by:

Perfect for if you don't want to buy a whole new matching kit. Works with all of the locking Thule products which keeps everything secure and keeps people from walking off with your gear. G



by:

Worked as described and pretty idiot-proof - push in and turn key. Used the same key as my existing Thule products. Appeared to be authentic Thule (A***** had some fakes for a while). Arrived lightning fast (thanks etrailer).



by:

Very pleased to be able to order Thule lock cylinders that match the existing locks I already have. Something you cannot do on most other sites, including Amazon. Product arrived quicker than quoted and without incident. Will definitely purchase from etrailer in the future.



by:

Lost this lock (and related components) by carefully placing it on my bumper and driving off . . . never to be seen again. etrailer was the only source that had all of the parts I needed in one spot. Not even the manufacturer had one critical component. But what makes it even better, is that etrailer had it at a lower cost. Plus, ordered late Sunday afternoon and had it by noon Wednesday with standard shipping!
Was very pleased that they carry all of the possible combinations, so was able to purchase a core that matched the existing key and lock of my multi-lock bike rack.



by:

Thule lock cylinders are easy to remove and replace with the Change Key and make it convenient if you have multiple Thule products like me with locks. I have a bike rack with built in lock, cross bars with locking footings, cargo box, etc. and they now all lock with one key because I bought replacement locks - highly recommend doing this if you have more than one lock code / key for your Thule products.



by:

This is the only place online I could find these. Works great, still a solid design after 25 years.

  • How to Remove Broken Key From Lock of Thule Roof Cargo Box
    I've had good luck in the past using dental pics, working at both ends of the narrow edge of the broken-off key at the same time. Once you get a portion of the key slid out you can use a pair of pliers to grasp and remove the broken off portion. Most hardware stores sell an assortment of dental pics, they're handy to have around. If that fails, the best course of action is to drill out the lock core, however this must be done very carefully. The best way to accomplish this is to start...

  • Replacing Broken N166 Key for Thule Pulse 615 Roof Cargo Box
    We offer replacement N166 keys as part # THKEYN166 as well as the replacement lock as part # THLOCKN166. To remove the existing lock cylinders and install a replacement, you'll need the # 853-1251 change key.

  • How to Remove Old Thule Lock Core to Replace it
    Can you get the lock unlocked? If so you can insert the Thule change key # 853-1251 into the core and then pull the core out all the way and replace it with a new one like the part # THLOCKN166 and then use the new key part # THKEYN166. To install the new lock core you'd just reverse the process described.

  • Key Alike a Sport Rack Accessory to Existing Thule Products
    Hello Todd. I have a solution for you, but unfortunately the lock and key set that come in the SportRack Trailer Combo, part # A32022 are randomized at the factory and can't be ordered to match. However, you can easily order the additional replacement cores with part # THLOCKN166 and get a change key with part # TH42BJ if you don't already have one to swap the locks on the kit to match your other Thule products. Additional Keys are available as part # THKEYN166.

  • Can't Remove Broken Key fro Thule Cargo Box. What Now?
    Thule unfortunately doesn't offer the cylinder or sleeve the lock core sits in as a replacement part. If the cylinder hasn't been damaged, there's a chance a locksmith could carefully drill the lock core out, because if that cylinder is damaged, there's not much that can be done other than using a couple of padlocks, hasps # H135-203E and # H115-204E staples to secure the box. It isn't a pretty solution, but it's less expensive than a new Thule cargo box.
