Average Customer Rating:  4.7 out of 5 stars   (102 Customer Reviews)

This swivel head design hitch lock from Master Lock secures your ball mount, bike rack or cargo carrier to your hitch.


Perfect for the 2008 Honda Element SC setup! Leaves room to put the cap on and still get the safety chains hooked up.


Yes I received it today and it is just what I need and wanted. Ordered some time ago took a long time to make it to the Mail.
Thank You


Item received and in good condition. Works well as expected.


Works great in securing my hitch. Etrailer always has what i need for towing and trailer components.


This lock is well made and works, but it is difficult to lock. It is designed with a spring-loaded and cammed locking mechanism so that you should be able to push the keyed barrel onto the shaft without using the key, but it is very difficult to do. I usually end up needing to insert and turn the key to get the two pieces to mate. This is not convenient when you are bending down and working underneath the truck's bumper. Pushing the two pieces together is already a two-handed job without having to turn the key. Other than this it is a quality product, but usability is very important.



Within 2 weeks this lock fell off while I was pulling a trailer, causing the hitch to pull out of the receiver. Luckily I had the safety chains hooked up so I didn’t lose the trailer in traffic. But I was stranded at the side of the road and had to walk to an auto parts store to get another hitch pin. This was a result of the locking mechanism being too difficult to secure. I thought it was locked correctly but obviously not.


This hitch pin lock has worked flawlessly for me over the last year since I purchased it. I have zero complaints.


Have used it on about 8 deer hunting trips with my storage rack. No complaints. It does what it is supposed to do. The dirt cover keeps the key hole clean and the lock clips onto the bolt easy. Also the bolt diameter matches the hole on my 2016 Grand Cherokee perfectly without any play.



The lock still works great. Hoping to put it use again soon.


Hitch cover looks great. Service from etrailer is second to none. Great communication and fast shipping. Will definitely be a return customer.

Thank you for checking in. I really like the hitch cover...the only problem is all of the yellow s have fallen out and the black is starting to come out as well. I know this is not your fault and your service has been great. The lock I purchased works really well.


For those of you who stay in motel/hotels while on the road, or leave your boat trailer in a parking area while having fun, trailer security is important.Thieves can unhook your trailer and make off with it when you're asleep or away. This handy little device locks your ball hitch into the receiver. Short of getting a Sawsall to cut things up, when used in combination with a coupler lock, this will keep anyone from unhooking you. It's more expensive than just a standard pin, but what are the contents of your trailer worth? This thing is well-made, and has a rubber cover to keep dirt out of the tumbler. It's definitely worth the money.


The built-in receiver on our Chinook rv had very little side room to insert and lock a locking hitch pin with which to secure its receiver extension. A straight-thru locking pin wouldn't work, but this swivel head locking pin, with it's 90 degrees different end latch came to the rescue. It gave the access needed to lock the extension, it feels solid, and has a heavy duty weather protection cap. Another super thing about it is the ease with which it locks. Leave the key in it and shove the pin shaft into the latch, and CLICK--it's locked. Unlocking is just as simple.


Good locking pin, not compatible with the bike rack we purchased as the pin hole is threaded for the bolt/pin the rack comes with.

Because of the threaded in the shank of the SportRack Ridge Swing bike rack you purchased, a standard locking hitch pin wont be compatible. Id recommend the SportRack Anti-Rattle Hitch Lock, part # SR0901. You can see this lock by using the link Ive provided:


I like these locks better because you can turn the head to face you and it's easier to put the key in.


great product...easy to use...and prevents hitch and/or cover from being stolen.

still on the vehicle and has been used all year. working out GREAT!!!


My hitch is very close to my trailer plug receptacle. It has always been a hassle to get the trailer hitch locked because of this tight fit. This lock design, with the outward facing key access has solved that problem.


Easy to use. The lock won't lock unless you have the key inserted and that is a very good thing. We've been using it for over a year now and it is working fine.



Works fine. We like it. Very simple and easy to use. You cant lock it unless you have the key in it. That is a big plus.


good quality good pricing fast shipping


The lock works as advertised. Simple, straightforward. Small point, when first inserting the pin through the receiver the O-ring can hang up on the receiver and make attaching and locking the pin difficult. This can be frustrating to account for on difficult to reach couplers (standard height SUV vs. lifted pickup truck). We’ll see how it holds up in the harsh environment it will be subjected to.


This lock is easy to use. But my overall experience with e-trailer was great. Placed the order online on Sunday night. Received the product on Thursday. Having the accurate tracking link sent to me via e-trailer to my email was very helpful! I’ll definitely do business with you again.


Good product, exactly what I was looking for.


This is a high quality, user friendly hitch lock. I purchased one from Walmart that took “Three Men and a Baby” to lock and unlock. This one locks with one hand and is a snap to remove. Delivery was supernaturally fast ( just as fast as [online retailer subscription service]) . I highly recommend this product and etrailer. com.


Have had on truck for a year. Recently changed hitch ball size. Lock worked easily. Stainless still looks nice. Good product.


I haven't used this yet, but I have tested it and it fits perfectly with my hitch setup on my 2014 Dodge Durango and looks nice. I like the cover to keep the key hole from getting ice in it since I will be traveling on the road in the winter.


Easy to take on/off. I like the security the lock provides.



Thank you for the follow up. I have owned that for 2 years now and I am still very satisfied with my purchase. I have recommended others to


A quality Masterlock device, as you would expect, that’s easy to open/close and does exactly what it’s supposed to in securing hitch. Good price, will look to buy again from Etrailer.


Hello... the products i ordered and received, was just fine..exactly what i needed.. 5 stars... with the exception of packaging.. the hitch wasnt wrapped or contained properly.. it was hanging out side of box. Had some scratches on it, but thats fine.. no problem.. just poor packing.. will be ordering from y'all again... soon..thanks
