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.

Etrailer sent me only 3 out of 4 lock cylinders. I contacted customer service and they promptly furnished the missing lock cylinder.

Fit perfectly



by:

I needed new locks cylinders for my Thule Ski Racks and found etrailers prices to be the best. They were delivered within the time frame mentioned and fit perfect.



by:

Ordered a new locking device for my Thule square bar. Easy to order, talked to a very friendly human. I loved that they had a video on how assemble the locking device. I was also sent several emails to let me know the status of my order. It was also less expensive than other sites



by:

I purchased this for my Audi A4 base roof rack system. One of the original locks fell off and this was a PERFECT replacement. The price was fair and the service (correspondence) from etrailer was great! Overall I had a wonderful experience and I wouldn't hesitate to use etrailer.com again.



by:

I recently got a Thule roof rack for my new car. I wanted to use just one key for all my locks in already in use on my other roof rack, bike rack and other Thule accessories. Etrailer had the lock cylinder number I needed and I ordered 4 more locks. They shipped them quickly and they arrived. They were installed and function as expected. Etrailer always has what I need at a reasonable price.



by:

A friend passed away leaving a car and bicycle rack that were to go separate ways but the lock had no key nor any key numbers. There were 2 new looking Thule N series keys with no lock to be found. A replacement lock was around $75 and switching wafer 2 for wafer 3 made 4/5 wafers fit and seemed good enough until I saw your reasonably priced replacement numbered cylinders. As you can see it worked perfectly.



by:

Thanks to etrailer I was able to add the lock to my thule bike tray without having additional keys to potentially loose. Price was extremely reasonable and shipping time was as listed.
Thanks etrailer!
Below is my mountain bike securely locked down to my Thule wide mouth bike tray on a 09 dodge journey.



by:

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.

Awesome service - worked with photo to help me identify the key needed! So happy there is such a service within the states. Very professional and recommend this website and team at etrailer!

Called Zack about replacement parts for my Thule 2 bike carrier. Parts arrived with great speed and frees shipping. All parts were as described and have been installed. Thank you etrailer sales and Zack O.



by:

I made sure to order the same lock that uses the same key as our Thule bike rack that attaches to our trailer hitch. No need to order the extra keys so that saved us some money and we don't need six copies of the same key!



by:

I have been a fan of Thule products for a long time now. I use their sidearm racks for all my bikes and love having the ability to use matching locks between my racks. This key cylinder was exactly what I expected and works as it should. I've had it for a year on my roof rack in all sorts of weather and it still works great.



by:

Exactly what I was looking for - three more cylinders keyed like three I already had so I can use one key for all my Thule products. I had trouble finding other places that would allow me to order a particular key, and all other options I found charged more (many came with a key - but I did not need more keys).

You can use the individual replacement lock cylinder in conjunction with your existing # TH544 Lock Cylinder Set. You will just have to make sure that the numbers on the face of the lock core all match. For example if your existing lock cores have a number of N052, then you will want to order a single replacement # THLOCKN052.


by:

The Thule bike rack from etrailer is excellent! And the customer service is too! Chelsey S. was my customer service person and she followed through and checked up all the way through. I had lost the lock off the rack but next day my husband found it in the street. Long story short had ordered it already and etrailer was wonderful taking the lock back. Did I say or if I haven't reviewed the bike rack yet I will - so easy to put on, take off myself, etc. Anyway from now on all my trailer stuff will be from this wonderful company.

  • How to Pick Out Correct Replacement Lock Core and Key for Thule Bike Rack Outway Short Arm
    Hey David, we can help you but I would need to know the key number/lock core number from the other locks/keys of your rack so that I can match them up. For example, if the key number you find is N181 then the correct replacement key would be # THKEYN181 and the replacement lock core would be THLOCKN181. Let me know what you have and I'll get you set up with what you'll need.
