This universal coupler lock protects your trailer from towaway theft. Lock codes to your vehicle's ignition key, and it's nearly impossible to pick or bump. Included lock, base plate with ball, and shackle fit most coupler and latch styles.
Features:
Specs:
Note: BOLT locks permanently code to only 1 vehicle. They cannot be re-coded or re-keyed.
To install this lock simply insert the ball into the coupler's ball socket. Insert the collar into the base plate until it's snug against your trailer latch and the holes align with the holes in the base plate. Insert the lock through the holes in the base plate, and use your vehicle's ignition key to secure it.
When you insert your own key into the cylinder, spring-loaded plate tumblers move up and down until they are matched exactly to that key. The first time the key is rotated, the cylinder is uniquely coded to that key. When the key is removed, the cylinder moves into the locked position. When the key is turned again, it will rotate to the unlocked position.

Super easy to key lock to my Ram key. Trying to eliminate as many keys as I can. As you can see in the picture, I also got the matching BOLT receiver lock.
No weather cover as on their other locks, but it has a sliding internal cover similar to your car/truck door lock. Solid and beautifully finished.
Thanks to Amy. She shipped this part and the third part that is on backorder will be shipped as soon as it comes in product is easy to key to your vehicle key.
Keyed to our 1996 f350 and using on our Demco hitch. Bought this with the plan to weld up some extensions covering the hitch bolts that connect to trailer. Should not be difficult since it is made from steel.
My 2010 Airstream trailer coupler has a curled lip on the collar which widens as you move toward the trailer. The 2-5/16" "ball" fit well as long as I slipped the U ring through the front slot of the red plate. I tried the back slot but the collar was too wide so the pin wouldn't go through. Using the front slot seems like the system will be secure enough but I would prefer using the back slot. The lock works perfectly with my 2014 Tundra key.
I don't have a center cut GM key just yet but my locksmith is hooking me up with an unused that's already been cut that he was using to bring perfection to the center cut key world when they were first introduced. I do know the bolt is the perfect size to replace the snap retainer on the yoke of our Curt 30K 5th wheel hitch to help keep it right where it's supposed to be, which is helping to protect our hitch to keep it from growing legs then strolling off the property. It's really discouraging when considering all the fellow brothers and sisters out there who are scheming, thinking up new ways to attempt to rip us off. I really never pictured 2025 to be so upside-down in the mindset between what's right and what's wrong. In the modern times, absolutely nothing is sacred or safe.
Works well but thought pin a bit long but maybe ok when combined with this complete tongue lock when parked. Again nice that it works with my Toyota tailgate key.
Using on my Aluma car trailer. Fits well and instructions well written. Can even combine with latch pin for added security. Uses my Toyota truck tailgate key as advertised.
Best addition you can add for trailers. I never have to go looking for keys. Had this on my last truck for the receiver and trailer pins. Only gripe is those are now useless.
I already owned one of these for my boat now I’m putting a second one on my utility trailer and I have one for my trailer hitch on my truck firm believer always nice to have only one key for all my toys
We've tried a TON of different coupler locks for our 2019 Jayco RV with an underslung coupler, and we ended up having to send them all back because they're too narrow. A year or two ago, after giving up on all the other brands from all the other sellers, I got on the phone with an e-trailer rep, and he dug through the available options to find one wide enough, and this one works!
Since it's keyed to the tow vehicle key, and since we sold our previous tow vehicle, I just bought another one because I KNEW it would fit, and it does. So thankful for this lock and for etrailer's help.
Good news is that it works like all B.O.L.T. locks I have with one key. Bad news is that there is no way to seat the cylinder COMPLETELY against the hitch, which leaves a small gap that a thief could get a hacksaw into. Still, the pros outweigh the cons.
Easy to use, works perfectly gets rid of unnecessary keys on ur key ring.
Excellent quality! Superior security! I have Bolt products on boat trailer and cargo trailer. The feature that all my Bolt products are all keyed to my ignition key sure comes in handy!
Easy to use.
The trailer lock has served us well. I highly recommend.
love this trailer lock and that I could key it to match my Ford Truck key. It is made of pretty thick metal and I believe it is better than anything I can purchase at the local stores. I'm very happy with my purchase as always with etrailer.
The fact that I don’t need to carry another set of keys makes these locks ideal for my situation. I use a pair of these on the back of my car hauler.
This is a nice secure coupler. It fits well on our 2 5/16 coupler. Be careful ordering as the key programmable lock is make/model/year vehicle specific.

This lock is still as new after over a year in the weather. The lock mechanism is still smooth and functional.

Looks like the original review referenced the padlocks. The trailer coupler seems very secure and the keying to the truck key is what seals the deal.
