Andersen Trailer Hitch Lock and Adjustment Pin Lock Set - EZ Hitch and EZ HD Ball Mounts - Stainless - AM3493

Average Customer Rating:  4.7 out of 5 stars   (64 Customer Reviews)

For use with EZ and EZ HD adjustable ball mount systems for 2-1/2" and oversize 2" receiver hitches, set includes a hitch receiver lock to secure shank to receiver and a locking adjustment pin to secure ball housing to shank. Stainless.


Perfect! Fits the 2013 factory Tundra hitch PERFECTLY. Same key system, locks ball mount to sleeve, sleeve to receiver. I had been looking for this type of hitch/key lock for some time and was very happy with all the help E-Trailer and Jena provided in getting me one of their newest items of their inventory. I'll keeping back.


A must have to protect your investment. One key for both locks a plus.


Works as described!


Very well made, easy to unlock/lock and the common key makes it easier to keep track of. My only complaint is that in the online catalog doesn’t indicate that these locks won’t fit the #AM3410 hitch that I purchased them for.


Works well. I like the positive lock fe ature.

No problems, still working well.
Roger L - 08/05/2022


Arrived quicker then I expected and the quality looks high quality.


Not what I thought. Did not fit my app lication.

This hitch pin set is designed to fit 2 inch and 2.5 inch hitches. The span of the hitch pin being 3.3125 inches.
-- Etrailer Expert Katrina B - 03/24/2022


I needed to pull my hitch to replace it with my receiver mount 4-wheeler hold down and the pin was locked up. It would unlock, but the 2 ball bearings wouldn’t let the pin out to allow the locking end of the pin to release. As a result, instead of using my incredibly efficient hold down, I had to tie down the 4 wheeler the old way and find a spot to haul my hold down home in an already filled truck.


The original item I wanted to purchase was out of stock so they came up with a great alternative. My items shipped out the same day and I got them in a timely manner.


Received product on time. The receiver lock for perfect on my Chevy 2500 with a 2 1/2" hitch. It is snug and does not rattle. The locking mechanism is very positive and you know that it is locked or you can't pull the key out. Only time will tell about the the manufacturer's claim of no seizing and no rust. The o rings look like they will deteriorate because half of the ring is exposed. Hopefully it is easy to find at a hardware store when it breaks down.


Works well, should just be included with hitch.

This pins work great for anti-theft, keys fit well and stay with the lock until back in place. Rubber caps are a bit loose, so I wouldn't bet on them sticking around forever.


I always get what I need from E-Trailer for a good price


I really like these locks. They have held up to quite a bit of abuse, especially considering one is used in a front hitch and sees all kinds of weather and road debris. The only issue I've had is the locks themselves get a little stiff (like any lock would), so a quick squirt of lubricant every now and then keeps them working smooth.


Great product - highly recommend
sturdy - easy unlocking with key
Like the rubber closure keeping the keyhole covered
So far no rust
Happy motoring!!!


First of all, etrailer has been my supplier of truck and trailer parts for years and a pleasurer to do business with, great service... The hitch locks where as advertised, the hitch was perfect!


The product is good, exactly as expected. etrailer ordering and processing service is also very good ... thank you. I wish they could avoid CA sales tax like last time I ordered. Shipping was a bit slow ... UPS takes their time.


The nice thing about this lock is the longer bar which was a better fit on my Toyota Sequoia hitch.




I ordered a pin lock set and a part was missing. Called there 800 number and they email me a shipping label to return the bad part. They shipped out my new one the same day. Very good service.


The product is fine but the wait time is too long for delivery!


I love these locks. Always easy to lock and unlock. I like the fact you can't remove the key until it's properly locked.


Works great, easy to use on adjustable hitch


Easy ordering, fast shipping, works great with new adjustable hitch....


No Rust on this lock after 1 year & the cylinder still operates smoothly...Great buy!


Nice lock would buy again. Thank you et railer.

  • What Locking Pin Can Be Used on the Andersen EZ Hitch and EZ HD Ball Mounts
    I have a solution for you. Andersen has the Trailer Hitch Lock # AM3493 that is designed to be used with the Andersen EZ Heavy Duty Adjustable Hitch, #EZ Heavy Duty Adjustable Hitch. The Andersen hitch lock pin is made of stainless steel with aluminum caps and has a breaking capacity of 30,000 lbs.

  • Can the Andersen Trailer Hitch and Adjustment Pin Lock Set Be Used on a Weight Distribution System
    According to Andersen, they do not recommend using any pins to attach the ball housing to the weight distribution system's shank which includes the Andersen Trailer Hitch Lock and Adjustment Pin Lock Set part # AM3493. They recommend that you use the nuts and bolts included with the kit. You could use the longer pin on the hitch pin hole but not the shorter pin on the adjustment hole.

  • Will Andersen Trailer Hitch Lock Set AM3493 Fit Hitch of 2017 Ram 2500
    Yes, the Andersen Trailer Hitch Lock and Adjustment Pin Lock Set # AM3493 that you referenced would work just fine in the hitch of a 2017 Ram 2500. It includes a standard diameter 5/8 inch hitch pin with a very wide span of 3-5/16 inch. So if you have a 2 inch or 2-1/2 inch hitch this would work well with it.

  • Is Andersen Trailer Hitch Lock and Adjustment Pin Lock Set Keyed Alike
    The 2 pins that come with the Andersen Trailer Hitch Lock and Adjustment Pin Lock Set # AM3493 are keyed alike but if you're wanting to get 2 sets of these there unfortunately isn't a way to get them keyed alike so you'll have 1 key per EZ Hitch or EZ HD ball mount.

  • Replacement Tube key Recommendation For An Andersen Trailer Hitch
    The keys you're looking for Andersen have been discontinued and are no longer available unfortunately. Instead, since a replacement key is no longer available I recommend getting a new lock like the: -Andersen Trailer Hitch Lock and Adjustment Pin Lock Set # AM3493. This kit includes 2 keyed alike keys, 2 keyed alike locks with a maximum weight capacity of 30,000-lbs. Attached is a product review video for you to check out as well.

  • Replacement Keys For A Anderson Rapid Hitch Lock
    When replacing keys on your Anderson Rapid Hitch Lock # 03003 we do not currently have the keys available for your exact core. The best option that we would have is for you to buy a whole new lock and cutting off the existing lock. The Andersen Trailer Hitch Lock and Adjustment Pin Lock Set - EZ Hitch and EZ HD Ball Mounts - Stainless # AM3493 would be a replacement. I attached a review video link below.

  • Recommended Hitch Lock for 3 Inch Factory Trailer Hitch on Ford Truck
    For the factory 3 inch trailer hitch on your 2018 Ford truck I recommend taking a look at the Draw-Tite Trailer HItch Lock # BD580412. This is the longest hitch lock we have available and it is designed to fit 3 inch hitches like what you have. It features a usable length of 3-1/2 inches. I do recommend measuring the outside width of your hitch receiver just to make sure this will be long enough. This lock features a heavy duty steel construction and a nickel finish to help resist corrosion....

  • Stainless Steel Locking Hitch Pin that Has 3 Inch Usable Span
    We have hitch lock # BD580400 which is chrome plated steel, not stainless, but has a span of 3-1/4 inches. And then we have lock set # AM3493 which is stainless steel, aluminum, zinc alloy, and steel for nearly 100 percent rust free corrosion resistance. The larger lock has a span of 3-5/16 inches. The shorter one only 1-7/8 inches.

  • Hitch Pin Lock with 5/8 inch Diameter and 3-1/2 inch Span
    We have a pin lock that's sold individually that has the 3-1/2 inch span you need with the same diameter as the # AM3493 but the included lock of this is 5/8 inch which is the standard hitch pin size. So for that we have the # WS05 which has a 3-1/2 inch span and a 5/8 inch diameter. For the larger hitch sizes like 2 inch and up (including 3 inch) the diameter hitch pin used is 5/8 inch.

  • Hitch Pin Lock for Trailer Hitch Made in USA
    For a standard hitch pin lock made in the USA we have the Deadbolt part # BD580405 that will work great. For a for a combination hitch lock and lock for Andersen ball mounts like the part # AM3493 that you referenced we do not have this application made in the USA. I attached a review video for this hitch lock for more info for you to check out as well.

  • Anti-Rattle, locking, Stabilization Pin that will not Rust
    I have just what you need, a stainless steel locking anti-rattle hitch pin for you. I suggest the Stainless Steel Locking, Anti-Rattle Threaded Hitch Pin for 2" Trailer Hitches part # SR25219. You will need a hollow shank for this to work. For a solid shank, you will want the Andersen Trailer Hitch Lock part # AM3493 for the lock in addition to our Brophy Stabilizer Bracket part # RHSB for anti-rattle.

  • Recommended Ball Mount for 2016 Toyota Tacoma TRD Off Road 4x4
    I did some research on the Toyota OEM ball mount PT228-35161 and it has a 2-3/4 Drop or 1-1/2 inch rise and is rated for 10,000 lbs. We do not have an exact substitute for that ball mount, but a good alternative with some options is the Ball Mount Kit for 2" Hitches - 7,500 lbs # 989900. For a fixed mount ball mount I recommend measuring for level towing with your trailer. I've attached an article to assist. Another option is the Ball Mount Kit for 2" Hitches...

  • Recommended Trailer Hitch Receiver For 2002 Dodge Dakota Quad Cab
    For your 2002 Dodge Dakota Quad Cab, I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver Class III - 2", # 75038. This hitch has a rating of 500 lbs tongue weight with is the amount of weight you can apply to the hitch itself and a towing weight of 5000 lbs. I've attached an article on determining tongue weight. Because you have used a bumper pull to this point, you will need to get a ballmount, pin and clip. I recommend the Rapid Hitch Adjustable Aluminum Ball Mount Kit - 2 Zinc...

  • Locking Hitch Pin Recommendation for B&W Tow and Stow Ball Mount
    Actually, the latest version of the # TS20050B (our part number # BW54FR ) Tow & Stow features an integrated anti-theft component as shown in the provided photo.. A slot is cut into the adjustment channel near the top of the shank. To remove the ball mount platform from the shank you will need to remove the entire ball mount from your hitch. Then remove the pins that hold the platform in place. Flip the platform around to the stowed position on the rear of the shank, and then slide it...

  • Is There a Locking Ball Mount Rated for Over 10,000 lbs?
    The only B&W Tow & Stow ball mounts we offer that have a towing capacity over 10,000 lbs and fit in a 2" hitch use a pintle hook, like # BWTS10055. There are adjustable ball mounts from other manufacturers that fit in a 2" hitch and can give you the capacity you need. The Andersen EZ Heavy Duty Adjustable Hitch # AM3298 is one of those options as it has a 14,000 lb capacity with the 2-5/16" ball and offers a maximum rise of or drop of 8".

  • Locking Pin Recommendation for the Flash E Series Adjustable, Steel Ball Mount FA42-00-2800
    As long as the pin diameter matches up on your Adjustable Ball Mount part # FA42-00-2800 with the part # C23556 the locks being a bit too long would not matter. Normally we would recommend the part # AM3493, but if the Curt fits it would work as well.

  • Replacement Dust Cap for Andersen Trailer Hitch Lock and Adjustment Pin Lock Set
    I may have a solution for you, but we do not have an exact replacement for the dust cover on the # AM3493. However, we do have 2 options depending on which lock dust cover you need to replace. You might be able to use the Replacement Dust Cover for Hitch Locks # e98923 which fits well on many different barrel locks from many other brands. The inside diameter of this cap is 7/8 inch. If your lock has a 1-1/8 inch diameter than the better replacement is # 340M55787-01.
