Video Transcript for Thule One Key System Cable Lock Review

Hey there safety conscious adventurers, Dustin here at etrailer. And today, I've got the Tooley six foot Brandon one key cable lock. This cable lock is a great add to cart if you're picking up a roof rack system or a bike rack here from etrailer. It's not only great for securing your bikes to a bike rack, but it also works with ski bindings, kayaks, and anything else that you can get a secure mounting point to. So you could put this on your bike and on your roof rack. It's a six foot long braided steel cable with a vinyl coating.

That's going to help prevent the cable from rusting, but also prevent the cable from scratching your bike or anything else you're using along with it. It easily loops through a secure attachment point on your bike rack. If you we're putting it on a roof rack, I would recommend looping the cable behind your legs. And then in this instance, we have a bike rack. So I would go through a secure point on my bike so that nobody can walk off with that.

Or with skis or other accessories like our kayak. It's just a matter of finding a secure point to loop that through, again, behind your foot. And then with our kayak here on the inside, we've actually got a nice point to loop it through so you can just ride it up right there into the kayak. On your skis a good point is to maybe go through your bindings. And don't sleep on the fact that at the end of the day, it still is just a cable lock.

So if you want to hop on your bike and head out for some froyo, take this guy along. That way, while you're inside cooling down, you don't have to worry about someone walking off with your bike. I don't know about you but one of the things I don't like about having so many accessories is all the keys I have to carry. And that's the cool thing about this is it uses Tooley's one key system. Now it does come with two keys.

It doesn't mean you only get one key. What it means is that you're able to key this alike with your other similar Tooley accessories. That your hitch bike rack or your roof rack. So what you can do is take the included blank key, and that allows you to remove your lock core and replace it. So you can get here from etrailer, a set of lock cores that match all of your accessories, and then you only need to use, like the system says, one key for all of your accessories. Once you get your new lock core in there, just go ahead and operate your lock a few times and it will be secure in there and you're good to go. And that completes our look at the Tooley braided one key cable lock..

The lock offers great security for our bikes.


I got this lock together with the replacement knobs for my Thule Spare Me Bike carrier. I bought the replacement arm knobs after someone stole one of them. The lock pretty held my bikes to the bike rack until this morning when some perp cut the cable with a bolt cutter while on a parking lot in Sacramento. Good thing my Specialized bikes were not taken as my friend came back from a local fastfood and scared the perp away. The locking mechanism was solid, being Thule -made; only the cable was defeated by a boltcutter. It hurts me that the cable lock set me back $35 that only lasted only two weeks. sigh...My wife's gonna kill me for this...


The lock worked well on a trip from Central New York to North Carolina.
But, after the trip the lock failed to work properly. was contacted and I was sent a new lock. Working very well.
Great customer service made me a happy bike guy!

Phil E.


Still functioning well! I use it all the time to secure my bike!


This is a great starter rack for your trailer hitch. I got it delivered in just 3 days! Great service!


Great product


I purchased a Thule hitch mounted bike rack, cable lock and Thule snug tite hitch lock. These are all great products and I have been totally pleased with their performance. We've taken a number of road-trips taking our bikes along, everything has worked beautifully and to our satisfaction. There are a lot of similar products on the market, and I'm confident these are among the best!


The Thule Cable Lock was less than two years old, minimally used and now broken. The internal locking mechanism broke and the master cylinder kept coming out with no ability to unlock the cable. Finally got it repaired enough to open so we could get the bikes off the rack - the lock is garbage.


We're very happy with the Thule 2-bike rack (TH958) & associated locks (THSTL2)& cables (TH538XT) we bought through etrailer.

This setup works great on the back of our 2012 Jeep Grand Cherokee with our two adult bikes -- we would recommend this combination to others without hesitation :)


These locks for some reason are not made well. This has nothing to do with etrailer, it simply comes down to the quality control with Thule. When I received this lock the lock cylinder was not installed into the lock like most Thule locks come. You most of the time have to install the cylinder.
It also comes with the two keys to open and close your lock, and it comes with a universal master key, which is used to remove the lock from your cable or set the lock cylinder into cable.
The inside of the cable where the cylinder goes was not fabricated correctly. The lock cylinder would set into the cable. After numerous tries I took this set up down to a lock store that sells Thule equipment. They pulled 3 of the same locks off the shelf that I brought in. 2 of the 3 had the same problem as I was having with the one I received from etrailer. They were nice and gave me one of the locks that worked, and took the one I brought in to send back to Thule with the other 2 for warranty. This is again in no way a bashing or negative comment for etrailer. The quality of this lock is horrible per Thule


I got this lock because it can be used with the Thule one key system. My roof racks, roof box, bike rack, and bike lock chain all have the same key now. That is convenient. I am SUPER impressed with Their prices are great but their customer service is exceptional. If I need something automotive in the future, I will surely check their website first before considering anywhere else to purchase it.


As always Thule puts great products!!! Very easy to use!!! I appreciate etrailer's great customer support!!

The Locks are working great! I would recommend them to everyone!!


In the times of covid, I ordered this rack in June, but it was out of stock.. I waited and waited, UNTIL I finally called the support line.

It took like 25 mins in the support line and I expected therefore a phonebank person. Instead I got Greg, who clearly was just a guy at this company trying to help out. He quickly found a trailer that was in stock (this one) and was truly just a boss of customer relations. 5/5 on that front! Personable and effective!

Then I got the mount. Man. It is really awesome, sturdier than i could have imagined, and I put my 11k bike on the back on a highway rush. Not trying to flex, just saying the mount was incredibly sturdy and I had a lot of faith in the hardware.

I would order again in a heartbeat! If you have any issues, just call the help line! If you get a delay, I think its because its real people on the other side. I really like this company! would buy again :)


The lock is good but it should be longer so you can lock your bikes to the carrier


Everything was of great quality and I was impressed with the quality of protective cap on locking device.

Suggestion if the cable could be another 1 to 1.5 feet longer. This way you lock bike carrier and bikes to trailer hitch safety chains attachment on hitch.


Great bike rack, however, it would be great if the racks hole in the input to the hitch was a standard size hole. Then you could use a standard trailor hitch lock, which I already have.


Thule products are simply top notch. Etrailer's delivery and feedback are how business should be done -- lightning fast and personal involvement that shows they care about their customers. I go nowhere else for my needs, and recommend them to everyone I know.


I'm very pleased. Ordered by phone and got great help to fit my 2010 GMC Yukon. The order arrived quickly and in good shape and after a quick read of the instructions installed the rack and tried it out. Everything works great and I look forward to many years of enjoyment as I travel the country with my new bike rack.


Solid lock. I wish it was longer or that they at least offered a longer version. I like that you can buy replacement locks or multiple locks so you use one key for multiple Thule products (in this case, I have the 990XT hitch and I love it!)


First time using hitch with bike rack on our Rav 4. Quite easy system to carry our bikes from Chicago to South Haven. The tilt feature is great for loading and unloading gear from hatch. Overall really happy with purchase and will recommend to friends!

More cycling trips on our horizon.


This lock came with the awesome Thule Bike rack, and was delivered within 5 days faster than the advertised shipping dates. Love the bike rack and lock! Thanks


I love the heavy construction of the bicycle rack. It will hold 2 bikes and does it nicely. My only complaint is the mount for the inside bike slides back. I had to devise a clamp to hold it in place. Annoying. In addition, it turns the bike back. Other than that, very satisfied.


Love our Thule bike rack; it is easy to use and convenient.


Great quality products. Got bike rack and trailer hitch in 3 days and on the road with it on the fourth day


This was a great purchase - product works just as advertised to lock down my bike on the carrier. Very easy to use.


Easily loops onto two bikes and the rack for an extra layer of security and peace of mind when transporting bikes.

  • Replacement Cable for Cable Lock on Thule Apex 5 Bike Rack
    I reached out to my tech contact at Thule and the integrated cable is not a replaceable part for your Thule Apex 5 Bike Rack. To secure your bikes, I recommend using a separate cable lock like # TH538XT. If it is a manufacturer defect, it should be covered by the manufacturer under your Thule Warranty.

  • Replacement Cable And Lock For Thule Vertex Bike Rack
    The integrated cable is not a replaceable part unfortunately. However I'd recommend to just use a separate cable lock like the Thule Cable Lock w/ One Key System Lock # TH538XT. Additionally, you can put your existing lock core into the cable lock # TH538XT if you wanted to retain your original keys.

  • Replacement Locking Cable For The Thule T2 Classic 2 Bike Platform Rack
    It looks to me like you have an older style of the T2 Classic bike rack. The newer models have a lock built into the handle of the arm, eliminating the need for a cable strap. I do have an option for you, however at this time neither we nor Thule offers this cable as a replacement part. You can use the Thule Cable Lock w/ One Key System Lock part # TH538XT as an alternative option.

  • Replacement Cable Lock for Thule Revolver 964 Bike Rack
    I may have a solution for you, but I don't believe the part you're looking for exists as a replacement part for your Thule Revolver 964 based off my research and a conversation with my tech contact over at Thule. Without knowing exactly which part has broken I can't confirm this is accurate but from what it sounds like, it does appear that using the Thule Cable Lock # TH538XT will be the best solution to replace the broken cable lock mechanism on your Revolver.

  • Thule Passage 2 Bike Rack Fit on a 2013 Chrysler Town and Country
    The Thule Passage 2 Bike Rack, # TH910XT, will fit your 2013 Chrysler Town and Country and you do not need locks to be able to use the rack. Some bike racks come with locks and some bike racks do not. A lock will not prevent the use of the rack. If you would like to be able to lock your bikes to the bike rack, then you could pick up the Thule Cable Lock, # TH538XT. I have attached a demonstration video of this bike rack on a 2013 Chrysler Town and Country without a lock for you to check out.

  • Should The Thule Frame Adapter 982XT Move When Not In Use
    Yes, there will usually be some play in the # TH982XT adapter bar and that is normal. That will not be the cause of problems. The ends of the bars do have different sizes. Typically it's the steering stem that requires the wider portion but as long as you get both the seat post and stem secured either way will work fine. If you haven't gotten a lock for your bike rack, the # TH538XT is a great option for securing your bikes once loaded.

  • Replacement Thule Cable Lock Solution
    I wish we could help but I checked with Thule and they don't offer the shorter replacement cable lock you send in pictures of. Best option would be a cable lock like the # TH538XT which is 6 feet long and you'd route it through your bikes and safety chain loops of your hitch and you'd be set.

    There is a way to lock the Rola Roof Mounted Cargo Basket, part 59504 (DISCONTINUED), to your Chevrolet Suburban, but part 59504 does not have integrated locks. What you can do is use Thule # TH538XT cable lock to lock the Rola Roof Rack to your Suburban to prevent theft. To do this you would just run the lock through the Rola Roof Rack and the cross bars on your Chevrolet Suburban. Rola does not offer any locking mechanisms at this time to prevent the basket from being stolen. Our representative...

  • Best Trunk-Mounted Bike Rack for a 2020 Dodge Caravan
    Thank you for racing for a good cause! To outfit your 2020 Dodge Grand Caravans with bike carriers without utilizing a hitch, your best option is to use a trunk-mounted carrier. With two bikes per Caravan, I recommend the Thule Passage 2 Bike Carrier, part # TH910XT. This can carry 2 bikes each and have anti-sway straps (which is obviously important for such expensive bikes). I've linked to a video review of this rack for you to look at. For security, I recommend getting the Thule Passive...

    The Thule Parkway 4 Bike Rack does not come with locks so I am not sure if you are referring to the Thule Snug Tite Hitch Lock part # THSTL2 or the Thule Cable Lock part # TH538XT. Regardless there is no special tool or procedure to free the lock core. If it has been locked for some time there can be dirt that gets inside and prevents the lock from being disengaged. I recommend spraying a more oil based product in the lock and letting it sit. You can try and tap it with a hammer to try...

  • Alternative Lock to Secure Kuat Transfer to a Trailer Hitch
    Bike rack manufacturers try to thread their pins and locks as uniquely as they can in order to make sure you use their product. The Advantage Threaded Trailer Hitch Receiver Lock # HE6033 has not been tested with the Kuat Transfer bike racks but it is unlikely to fit. What you can do instead of using a hitch lock is to use a cable lock such as # TH538XT to secure the rack to the safety chain loops on the hitch.

    The bolt you mentioned is not meant to be secured by a lock. If you wish, you could use thread locker like Loctite # LT37420 to make the bolt more difficult to remove. The fact that two wrenches would be needed to remove the bolt should be sufficient deterrent for all but the most determined thief. Using a cable lock like # TH538XT ran through the loop on the shank or through the safety chain loop on your hitch should secure the bikes as well as the upper portion of the bike rack.

  • Is the Thule No Sway Cage Bike Stabilizer TH955 Necessary for a Thule Parkway Bike Rack
    You do not have to have the anti-sway cages, # 753-3530, if you do not want them. However, using them greatly reduces the movement of the bikes and I think it is well worth it to add them. I know on my Thule bike rack, before I strap the anti-sway cage to the bikes they do move quite a bit. But after strapping the bikes to them, the bikes hardly move at all.

    You can change the lock core in the Thule Cable Lock, # TH538XT, to match the lock cores on your Thule bike rack. You will just want to buy a replacement lock core in addition to the cable lock. The part numbers for the Thule replacement lock cores begin with THLOCK and end with the part number. For example, if the number on your current lock cores is N117, then the part number you will want to order is # THLOCKN117. If you want to tell me the number on your current keys or lock cores,...
