Video Transcript for Thule Hitch Locks 753-3725-02 Review

Today we're going to be taking a look at the replacement lock housing for the Tooly snug tight hitch lock. This unit simply replaces the lock houser for the Tooly STL2 Snug tight hitch lock and anti rattle device. It's going to include the flip up cover and it's going to include the plug. These atoms are designed to keep dirt and grime out of the lock housing. The flip up cover snaps into place so you don't have to worry about losing that or that accidentally opening. That's nice design of the unit. It snaps into place and it does require a Tooly one key system lock which is going to be sold separately and that would insert and install in this area right here. That's going to do it for today's look at the replacement lock housing for the Tooly snug tight hitch lock..

Lost key so ordered new lick and key set. Also ordered wxyra set of wheel straps. Everything works perfectly! Love the parts and bike rack. Plan to order other replacement parts soon, as backup.


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.


Great service, prompt, easy, fast delivery, and the product itself (which was a replacement) is actually better than the part I was replacing. I have a Thule T2 classic 2" hitch rack, and the snug tight lock thing that locks the rack to the hitch so someone can't take the rack off your vehicle was lost, so I needed to replace it. I like this replacement better than the original - it feels more secure and stronger and sturdier. I will definitely return here for more trailer/rack needs in the future! thank you!


The lock fell off my bike rack pin. This replacement worked perfectly and was delivered quickly.

I have used etrailer for many towing and trailer parts over the years and the service is great!


I lost the Thule Snug Tite lock for my hitch-mounted bike rack. Buying the cylinder that went with the key I already had, plus the housing and the universal change key, and I was all set again, for about half the price of buying the full lock from Thule! Works great!



Still great, we use it 3 seasons of the year.


Percect solution to securing my new Thule bike rack hithe extension, while using the spare lock cylinder that came with the bike rack. One key to rule them all. ;-)


The product is just as described (with the exception of the THULE branding on the cap. By purchasing this lock housing and the replacement threaded pin, I saved about $25 off the THULE lock set.

I have made several purchases from They have always shipped very fast and have excellent customer service.

Bruce P.


Perfect! Working as designed and have met or exceeded all of myexpectations. E-trailer hitches are the best!


Customer Service: Carol C. from etrailer provided excellent customer service. I'll be back.

Product: This is an OEM Thule product, so it's as good as it'll get from Thule.

Price: Cheaper here than Thule's site with an added ProDeal discount code.

Shipping: Relatively slow, but worth it for the price (I wasn't in a hurry anyway).


I had lost the original lock for my Thule hitch pin. I thought I would have or buy a whole new one. I called etrailer and talked to Tommy. He was able to set me up with this replacement lock. While we talked he also set me up with extra keyed alike cylinders so I can get all my Thule stuff on 1key. If you are having trouble don't hesitate to give them a call.


I needed to replace the lost hitch lock for my Thule rack. Every other source of this was charging about $51 for the whole assembly, which was far more than I needed. etrailer was the only place I found that sold just the lock body, and for one third the cost of the full assembly. It needs a lock cylinder to go with it, but I wanted a new one anyway to match my other Thule products.

Very happy with etrailer - they had a slight unplanned delay and made sure I was kept informed at every step and easily able to cancel if the delay was a problem (it wasn't)


Great service, website, and shipping. We find everything we need when other retailers do not carry the parts we are seeking!


Not much to say about it...chances are if you are buying one of these its because you somehow lost yours like I did. The cost was reasonable, EXCEPT for the fact you ALSO have to buy the lock core . Its still cheaper than the $90 pin and lock replacement combo, and much cheaper than losing a $400 bike rack...
Pro tip: buy the core that matches your key, otherwise you will have to buy a core AND a key.
Pro tip 2: Double check that its securely locked on the pin before you drive away :/


Our original lock fell off the hitch pin cause it wasn't locked in place (always check to be sure it's locked in place). Received my replacement lock cylinder and housing within a few days of ordering it - very quick service. The lock works great with my Thule keys and I am very happy with my purchase. Half the price of similar locks where you have to buy the replacement keys.


The one I received did not have Thule on the lock cover as shown in the photo. It is blank. Lock works just like the original one that came with the rack. As described, quick shipping, purchased for second Thule threaded pin and lock assembly to keep in second vehicle. Very happy with


Doesn't have the Thule cover but accepted the Thule lock cylinder pretty easily.

Mr B.


Working like a charm. Like I stated before nomThule cover but adequate.


I bought this product along with the bolt for my Thule bike carrier that I bought used and didn't include one. It has worked perfectly the last year, and if it isn't OEM, I cannot tell. It works exactly as expected, and so far, no one has stolen my Thule bike carrier. Highly recommend if you need a replacement.


Product was not what I needed and this was after sending pictures of the bike rack. Will probably be able to use the locking system for the roof rack, but certainly not the bike rack.


I lost the lock on my Thule hitch pin and was able to order an exact match from etrailer. I was able to use my existing keys. Ordering was easy and shipping was fast. They are a great company.


Exactly what I needed to replace the one I lost because I didn't check that it latched properly onto the hitch security pin. The one I received was unbranded (no Thule logo on it) but works exactly the same as the original that I lost.


eTrailer was way more helpful than thule, who wrote me off when I told them I had a problem with my snugtight lock. It was simple to get a new lock and matching core from eTrailer! Thanks!


I ordered a new lock mechanism for my Thule Doubletrack. After several years of use, my old one had gotten dirty and corroded inside. eTrailer had the part and shipped it to me quickly. Thanks!


Product was shipped fast and received ahead of schedule. Product as advertised no issues. I'll be back for other trailering needs.


Exact replacement for the original hitch lock, but without the white Thule logo on the cover flap. Works perfectly with the new lock core I ordered as well.


Purchased the locking hitch, replacement housing, and a new core to match my other locks. Works great and at a much better discount than purchasing the entire unit from another retailer.


it is an excellent alternatives to thule hitch lock housing. it is almost half the price and work just the same. The only difference is that there is no "THULE" stamp on the lock.

  • Will a Thule Lock Fit a Kuat Transfer Bike Rack
    I cannot guarantee that a Thule lock will fit a Kuat Transfer bike rack. What I recommend is the Kuat lock set for the Transfer 3, # PTSCLK13, for a couple of reasons. First it adds not just a hitch lock but also cable locks for each bike and all will use the same key. And second even if the Thule lock fit you would still have to get the actual lock cores and keys separately using # TH450200 and the total cost would be more and you would get fewer locks than if you went with the Kuat lock set.
