Most Popular Standard Pin Lock for Car

I have used this locking pin a few times now and it works great. Fits my class 1 hitch receiver well.

Excellent Trailer Hitch Receiver Lock, works very well!

The product looks to be a good quality item. But it is hard to rate something that stops bad things from happening. It does provide that first important thing: deterrence.

The lock-to-receiver is great, but the hitch lock-to-ball was too small diameter. I really didn’t like it so just stayed with my master lock.

Always good to get my trailer supplies here. Very friendly staff and very knowledgeable. Quick delivery as well

Installation was exactly as shown… very prompt delivery too.. excellent customer service

I had this hitch on my Jeep for 10 years. When the Jeep went south I got a Tacoma but wanted to put the Orange Stinger on the new truck. I had no idea they even made different length pins. My old one was too short. Found this guy on etrailer and it is long enough, and then some. Looks like padlock design is easier to use than the flush button end thingy I had before. The rubber dust cover I am not so sure it will be there for long as it just semi-snuggly slides over the end. But I am happy with this pin so far.

When purchasing the item I was unaware the country of origin was China. Not trusting Chinese quality I’ll search for another unit to use for heavy towing.

My wife and I bought a set for our utility trailer in 2018, and we were very pleased… We still use it. Last year, we bought the same set for our new boat trailer, and it works perfectly. I’d highly recommend this package.

Great kit with common keys to keep our trailers close by and under our control.

I have two curt channel hitches on two different trucks and it was hard to find a quality extra long hitch lock. These work perfect!

I just received the trailer locks and they were the perfect size and good quality.

This is probably one of the best stainless hitch locks of the regular through-pin style locks. It installs flush, and uses a solid pin. The locking side is also beefier than most, and sits tighter and deeper on the pin than most other pin locks - making it harder to try and hammer it off, or getting at the pin with a cutting tool. The lock uses large solid ball bearings for the lockup, and a disk style locking mechanism, which is harder to pick without specialty tools. So overall, one of the best regular pin style locks. We towed a 6'x12' that weighed around 6,000lbs from PA to FL without any issues with the pin-lock. We actually had to disconnect our trailer along the way, a few times, and the pin was easy to work with, and the lock really smooth. Don't hesitate to get it.

I purchased this Bulldog pin for my 2015 Yukon with a factory installed hitch. In this application this Bulldog hitch pin fits very well. I selected this pin due to its simple design and the generally compact diameter of the lock cylinder and the pin's beveled head-end. The lock cylinder diameter is import since GM penetrates the nominal 2" ID hitch tube through a steel bulkhead. There is only 7/16" distance between the hitch tube's nominal 5/8" clearance hole edge and the face of the factory bulkhead. Also, the hitch tube is fillet welded to the bulkhead. Thus, both the pin head and the lock cylinder need to have some relief (i.e. the bevel on the pin head-end) in order to clear this external bulkhead weld. Most of the above fitment concerns are overcome by the Bulldog pin's grip length being greater than that listed on the etrailer site (and in their videos as well). Specifically, the grip length is 2-11/16" rather than the listed 2-1/2". See the attached photos. Note that in the first photo the lock cylinder is firmly seated on the ball locking end of the pin. In the photo note that the cylinder is fully engaged and locked, which would not be possible if the cylinder was not fully seated on the pin end. The first photo shows the dial caliper fully closed and properly reading zero. Also note that the GM hitch tube is 2-9/16" square (outside dim.), thus technically a 2-1/2" pin grip length would be inadequate in this application. Since I have a metal turning lathe I was prepared to machine the pin a slight amount in order to make it fit. Thankfully, this was not necessary since the grip length is 3/16" greater than advertised. The pin is Chinese made in "stainless steel". I did test the pin with a magnet and it does appear to be austinitic (high enough in Ni and Cr alloys) since the magnet had no attaction to the pin. I do like that the lock cyklinder has an internal o-ring to help keep out "road splatter". I also gave the lock cylinder a short squit of WD-40. In sum, a well designed rugged product at a fair price.

The lock is high quality and I like the fact that it is stainless steel. Works fine with the bike rack (1.5 inch receiver pin easily goes through the rack on a 2 inch receiver). Saves a lot of time over having to bolt things together every time I want to take the bike's out.

Package was opened upon arrival.

etrailers blue ox Hitch receiver Lock works great I’m confident no one can mess with it while I am at dinner or at my campsite or just going into a gas station etrailer has what you need very good business

A must have your hitch receiver safe from being stolen

I cant' say enough about how helpful everyone is at e trailer! The Customer Service is Excellent and the photos, videos, and pictures are incredibly helpful with installation and use. A Personal Thank You to Alex who has basically been my Personal Concierge at e trailer, Thank You Alex!!

The hitch receiver lock is well made and simple to use.

I bought these along with the Andersen 2.5 inch receiver, 10 inch drop hitch - etrailer AN86VR- and they fit perfectly. They are 2 different lengths, the slightly longer pin is used to lock the 2 pieces of the Andersen hitch and keep them together (the ball assembly and the drop), and the other slightly shorter pin is used for use on the truck's receiver to lock the hitch up to the truck's receiver. The clever thing about these pins is that the key will literally "pop" out automatically when you press the locking pieces together. No spinning, or pulling to make the lock let go of the key. This is a very nice feature. Leave the key in the lock, press the 2 pieces of each locking pin together and the key drops in your hand with the lock secured.

Works great for our various race boats with all different trailers

I have not yet had a chance to use this lock as I just got it after getting home from a long road trip. However, I have other MasterLock locks for my flat tow set up. I really like these which is why I got this one to replace an older lock that had some rust issues. I'll follow-up once I get some extended use.

It's easy to lock and unlock, but since I'm only using it with 1 vehicle, I'll probably just leave it attached. Even with the dust cover, I figured it was a good idea to squirt lubricant into the keyhole. Along with the ball-hitch lock I got from etrailer (also excellent) it provides peace of mind.

Not easy to find a pin for a 3” receiver. My 2017 Ford F-250 Super Duty has a 3” hitch mount. This pin works great with my B&W Tow and Stow three ball hitch. For the money I spent on that hitch I needed to be able to lock it to the truck. This pin is perfect. I did have to grease the pin to get it to fit into the holes but it did eventually go once I got them lined up.

Amazing customer service and shipping was fast. They also followed up with us to make sure we got our shipment and that we were happy with the product.... That is a thing of the past that I miss and etrailer seems to still hold up those values.. Highly recommended!!!

I have owned two of these for a year now. And both of them are still in excellent shape the one on my truck and camper stay on year round.And neither one of them show any wear at all. And both work flawlessly yet. If you want a coupler and hitch lock keyed the same. I would highly recommend you by this set. And you can't beat trailer price and shipping rates also.

Works great, 1-key fits both locks!

Make’s connecting and disconnecting quicker.

Love etrailer Fast Reliable

Fit is perfect for a 2.5” receiver.

I hate this lock. Why? Because it requires three hands to operate it, and so it's incredibly difficult to install it by yourself. You need one hand for the key, another hand to hold the lock end, and a third hand to push the non-locking end tight against the receiver. I had a locking pin then went with a trailer I sold, and I wish I knew which brand it was, so I could get another.

It is a high quality product at a reasonable price - which is all I ask for for — etrailer delivers as always!

Toyota Tacoma trucks have a double width at the hitch pin area that is exactly 3". So, you're stuck buying a larger pin than necessary. This pin has a 3" span and it's made for the 2" hitch. Problem solved!

The hitch receiver lock was perfect for our setup and provided the security we wanted when towing our vehicle behind our motorhome.

The hitch pin itself appears to be a well-made, functional product. My problem is that I purchased it for my 2018 Chevy Duramax 2500HD. As those of us who own 2500HDs know, the hitch receiver is a 2.5" receiver rather than a 2", so that it can accommodate Class V hitch equipment. Most locking hitch pins are too short to work effectively which is why I purchased this one. Unfortunately, it appears that the way the tow-chain holes on Chevy's hitch are positioned, this pin blocks the use of the holes with the chain/hook makeup I've got. Will probably need to purchase shackles for the chains to make everything work correctly.

Last year I bought a flat tow set up for my jeep and Rv E trailer delivered me a great set up Hitch. Hitch locks. Cables. Demco braking system. Base plate and plugs. Easy to install and great towing

The locks worked well for Fastway trailer hitch.

This lock is totally awesome! Very easy to install and makes it very hard for to steal your accessories. That is why I purchased this lock. They stole my trailer hitch cover because I did not have a one. So I am very satisfied now that they will not be able to steal my cover. Highly recommend this product.

Recently purchased a Roadmaster High-Low Hitch adapter #RM-048-8 and a Bulldog receiver lock #BD580401 from etrailer.com. The products were unremarkable and the same as you can purchase anywhere. The real plus was the price and fantastic customer service (products were shipped the same day as ordered and received 3 days later) from etrailer that made the difference to me . I will always check etrailer first for my towing needs.
