Atwood 89006 Lock Diagram

The AMPlock from Atwood obstructs access to your trailer coupler to prevent would-be thieves from hitching your trailer to another tow vehicle and driving off with your gear.


Secure Locking Mechanism

This coupler lock has a disc tumbler locking mechanism. Unlike locks that use vulnerable spring-loaded pins, this ultra-secure Abloy-style lock is bump-proof. The cylinder has a series of rotating discs that can be correctly lined up only when you turn the corresponding key. Two identical notched keys are included to operate the lock. Because these keys feature 1 of nearly a million possible key codes, it's extremely unlikely that another individual will have a key that can open this lock.


Durable Construction

This heavy-duty coupler lock has a cast iron lock body, a steel locking pin, and a rust-resistant powder coat finish. The lock body is shatterproof. And hardened washers around the tumbler make it especially difficult to drill through the lock core.


Quick, Simple Operation

To install this lock on your coupler, insert the key and rotate it to release the locking pin.

Atwood Receiver Lock Operation

Slide the lock body onto the flat lip of your trailer coupler. Push the locking pin into the hitch ball socket to engage, rotate the key back to lock the pin in place, and remove the key.

Video Transcript for Review of Atwood Trailer Coupler Locks - Surround Lock - AT89006

Today, we're going to take a look at the Atwood Amp Lock underslung coupler lock. This is going to work for up to two and five 16th inch ball couplers and it is made of cast iron. This is going to be a really easy way to secure your trailer to make sure it doesn't disappear on you. This is going to again, fit on underslung coupler styles.So basically, you'll just unlock it, and that center pin will be able to drop down, and you can slide this over that coupler and keep it from going anywhere. Now again, the body is going to be made every very durable cast iron so we don't worry about it getting damaged from any freezing, it's not going to shatter.It's going to be pretty hard to burn or drill through this. It's very, very durable with a nice powder coat finish, so we don't have to worry about it rusting out.

As you can see, every surface there is going to be covered with that powder coat, so even on the underside. So it's going to be a really nice heavy duty long lasting coupler.And we'll have that rotating disk tumbler for our lock mechanism, to make sure that is going to be very secure. As you can see once it's locked into place, it's going to keep everything nice and tight. Again, this just slides over the coupler lip, and bald coupling portion, and keeps it from being able to be coupled with someone else's trailer.Get Two keys, and there's a lot of different keys you can get out there so it's not like anybody can just walk up with another key and take this. Does have a hardened washer inside to prevent any drilling into that lock core, and the locking pin itself is going to be made of a sturdy steel construction.Now this is able to take coupler sizes that are up to four and five eighths of an inch wide.

So you can see there our opening is going to be about four and five eighths of an inch, and can also take up to about two and a half inches. It's just under two and a half inches of usable space there.Overall, it's going to measure about four inches front to back, and about five and a half to the widest portion side aside, and overall it's going to be about five inches tall. So really quick, easy way to keep your trailer safe and secure. And that's going to do it for our look at the Atwood Amp Lock underslung coupler locks for two and five 16th inch ball couplers.

I just got the AT89004 hitch lock and I really like it. It is very heavy duty and fits very snugly. It would be extremely difficult to steal a trailer with this lock on it. I am very happy with this purchase! I previously was using one of those yellow locks that felt like it was made of cheap metal.... This lock is in a totally different league. It is definately worth the extra money 229756

Before ordering, measure your coupler. This lock does not fit my Walls Cargo trailer. The lock’s pin appears to be 1” gap from the collar of the lock. Our Wells Cargo coupler measures 1.25” from front of couple to the hole: too far. If you can’t confirm it will fit, recommend not ordering. This lock is heavy and return shipment will be pricey. 501522

I purchased this lock to go on my [email protected] 320S trailer. This trailer used the Atwood Channel Tongue Trailer Coupler - Yoke Latch - Black - 2" Ball. It fits perfectly on the coupler, I did have to raise the coupler ball latch for the lock to clear. I am very happy with the lock. etrailer was great to deal with. 476694

Review from a similar Atwood AMPlock Coupler in Trailer Coupler Locks


I tried the Reese ball coupler lock and the hoop part that goes over the ball barely fit my 2 5/16 ball coupler on my Haulmark race trailer, such that someone could pry it off because of the gap left and the key tumbler lock had no hardness protection. So my friend showed me videos how easy the Reese was to break off by theives. So I did some research and found this Atwood lock is unpickable, unbreakable and has a hardened tumbler. It fits great and gives not gaps to fit tools in to lock pin or leverage on! Great product and great shipping and customer service by etrailer! 527672

Review from a similar Atwood AMPlock Coupler in Trailer Coupler Locks


This is an excellent product, but it wouldn't fit on my hitch. The domed ball receiver was too wide. Not the lower lip width, but the actual upper portion of the ball receiver. The trailer lock is only 3" wide in the very top of the lock, my domed receiver width is 3 1/2" wide. I thought the next size up AT89007 which accommodates a 5" lower lip would fit, but the upper dimension is still only 3" wide, so that wouldn't work either. I was able to cut off a 1/4" on each side of the upper lip and it worked great. The service reps at etrailer.com were very helpful, but more information is needed on their web site. 208354

Review from a similar Atwood AMPlock Coupler in Trailer Coupler Locks


Gave this lock 5 stars because I can't think of anything negative about it. It's heavy, strong, of simple construction and the locking pin is very substantial. I doubt a hammer of any size will do much damage. And if anyone tried to pick the lock while it's attached to my travel trailer hitch receiver they would have to lay on the ground on their back in the attempt and thereby soiling their bad guy clothes. That's probably enough of a deterrent for some right there. It also has a funky design of a key so I imagine the lock is no push over in its complexity. Anyway out of all the hitch locks I looked at this one Impressed me as the best of the bunch. 374249


Comments

No complaints. Still just as solid as the day I bought it. And yes it wobbly as some commenters here have said but that has had no affect of its ability to perform as a very secure locking device.

Review from a similar Atwood AMPlock Coupler in Trailer Coupler Locks


This tongue lock will be installed on my car hauler as soon as I can find the key for the rinky dink lock I current have on there. No way someone will easily cut this off! My only concern is there appears to be a grub screw, that retains the locking cam in position, located up under and around the lock in a difficult place to see. I think it's extremely unlikely to happen but it might be that someone familiar with this style lock could drill the the grub screw out which might drop the locking pin and allow the lock to be removed. ? I'm going with it anyway because it's the best I've seen. 234222

After thoroughly searching for a quality coupler lock for my new trailer I decided on the Model AT89005 from etrailer.com. It is very hefty and well constructed and contains a top quality German ABUS lock. My trailer has a rolled lip at the front of the coupler and this lock with a 3/4 inch opening will allow you to slip it over this style of coupler. You simply unlock the lock, allow the cylinder to drop down, remove the key, install the coupler lock, push the lock cylinder up into the receiver and you will hear the unit click into the locked position. Very easy and smooth operating mechanism. 459209

I Like this trailer lock. I have a 2 inch coupler on my trailer that is a little thin so I welded a 1/2" thickness of steel to the nose of my trailer to take the wobble and space out of the nose for the lock to fit snuggly. I love the lock mechanism & key Nice design. We will see how it hold up in the cold Michigan weather for Locking & unlocking. I pick this lock because it fits 2 inch and 2 5/16 for I have multiple trailers. 430800

Review from a similar Atwood AMPlock Coupler in Trailer Coupler Locks


I bought and returned a couple different coupler locks from other manufacturers. Both were in the $25 to $30 range so you can imagine which ones they were. After looking at the brand name on the coupler of my travel trailer I decided to go with the Atwood lock two see if it would fit any better. Trailer has a two and five sixteenths ball the Atwood was made specifically for that coupler. No doubt for that reason, it seems to fit fairly well, although don't expect it to be tight it has a little bit of wiggle room although not much. It's fairly well made and sturdy the locking mechanism is well-placed and seems secure. I believe it would be difficult to remove although like any lock not impossible. etrailer handled the transaction flawlessly and kept me in touch about my order from the minute I ordered it online until it arrived at the house. I would definitely order from them. 471801

Just arrived today and installed the lock on my 2 5/16” coupler on enclosed snow machine trailer. It’s very solid, even a bit heavy (which is fine). It’s a little wobbly after installing but I expected that. I couldn’t get it off without damaging it so it will certainly keep the opportunistic thug a bit more honest. I am very happy with it. Keys are very unique which I also like. I would buy again for sure. 483277

I am pleased with having purchased this AT89008 coupler trailer lock. It arrived in less than 48 hours from when I ordered it which means I was able to secure my camper trailer quickly.

It did not fit-it was about 1/4" too small for my trailer...may grind to fit, but have not yet. John T 425641


Comments

If your maximum coupler width exceeds 4 inches this is including the lip then this trailer lock will not work for you. Also please measure the lip thickness. A lip thicker than a 1/2 will not fit inside this trailer lock. If the issue is the lip on your coupler is too thick then I recommend part # DT25013KA
Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers
$47.36
. This Fastway universal trailer coupler lock still only fits couplers that are up to 4 inches wide but the lip thickness does not matter with these universal locks.

The lock appears to be very well made and fit my cargo trailer coupler quite well. I installed it in less than 30 seconds and was able to remove it in the same time. There is slight side to side free play but it isnt a concern. It looks like the only way this lock could be removed is either with the key or a lot of grinding. It is thick and sturdy. I think a thief would move on to something easier to steal if they saw this lock. 390814

  • Trailer Lock Recommendation for Coupler that is 5 inches Wide

For a wheel lock we have the Stallion Wheel Lock part # 288-02020 which would be a great option. Then for a lug nut lock set we have the part # RG01-150.
