Are you afraid that your trailer, RV, or camper could be stolen while you are away? If so, you’re reading the right article because we will be discussing some of the best trailer coupler locks on the market.
When it comes right down to it, this might just be the best trailer coupler lock available now. For one, this model is made with ballistic-grade nylon, specifically the housing; this is very durable.
It is extremely resistant to heavy and repeated impacts, such as sledgehammer strikes, and it’s almost impossible to drill out. The lock itself is corrosion-resistant, which is perfect because it will likely be spending time outdoors.
Keep in mind that TRIMAX is one of the world’s leading brands in terms of lock manufacturers, and to make life easier, the Ultimate Universal Solid Hardened Steel Unattended Trailer Lock features a one-size-fits-all design, so it should work for any trailer coupler.
To ensure that the keyhole is safe and does not get moisture, dirt, or grime in it, it comes with a sliding cover. The locking mechanism features a dual-ratchet locking system with a 7 pin design for the ultimate in security.
- Resistant to drilling, impacts, picking
- Should fit all trailer coupler sizes
- Sliding keyhole cover
- Dual ratchet/7 pin design for great security
Key needs to be turned to secure the lock
As the name implies, this lock is universal, so it should fit most trailer couplers. However, this lock will fit all 1-7/8″, 2″, and 2-5/16″ trailer couplers, so it may not be 100% universal.
The Masterlock Universal Trailer Coupler Lock is made of solid metal, so it is very durable, and it is resistant to physical damage; no one will hammer this lock off your coupler.
The Masterlock Universal Trailer Coupler Lock also comes with an advanced locking mechanism that is fairly resistant to picking and prying.
This lock comes complete with a bright red finish. This red color is intended to deter thieves from trying to mess with the lock, although we suppose that it also makes it much easier to see.

- Resistant to impact damage
- Should fit most couplers
- Deters thieves
- Highly visible
- Can be a bit sticky
Unlike some of the other models, the REESE Towpower 72783 Universal Coupler Lock is truly universal and it should fit any trailer coupler sizes. What is also convenient about this lock is that it features an adjustable design with 11 locking positions.
The REESE Towpower 72783 Universal Coupler Lock features a ratchet design, something else that helps maintain a high level of security. Thanks to the premium-aluminum body and the heavy-duty steel lock bar, this is about as durable as it gets. It is extremely resistant to various forms of thievery including prying, picking, drill outs, and simple blunt force.
The REESE Towpower 72783 Universal Coupler Lock is made with a visible bright yellow design, something that is said to deter thieves, although, once again, this does also make it highly visible and easy to spot.

- Should fit all couplers
- Theft deterring design
The key movement is sticky
Something we need to say about the Tow Ready Gorilla Guard Coupler Lock right off the bat is that it is specifically designed for 2-inch trailer couplers. As long as the coupler width does not exceed 3-13/16 inches, and the height of the lip does not exceed 5/16 inches, it should work just fine.
The Tow Ready Gorilla Guard Coupler Lock is a simple keyed lock and it does not require any tools to install.
It is made of solid metal, so it should be tough enough to resist physical damage, such as being struck with a blunt object. This lock is also designed to be drill, pry, and pick resistant, although if you have a good hacksaw and a few minutes, you might be able to get through it. That said, it is highly resistant to tampering devices.
- Drill, pick and pry-resistant
- Easy to use
- Not very resistant to sawing
- Only for 2-inch couplers
As with the previous model, the AMPLOCK U-BRP2516 RV/Trailer Coupler Lock is also not universal. It is designed to fit trailer couplers that are 2- 5/16 inches, so be sure to measure your coupler before buying this lock.
This lock has to be one of the most durable, as it is made with high-quality metal, and for one, it is designed to be weatherproof and resistant to rusting. Moreover, due to the high-quality design, breaking it off with brute force is nearly impossible. We also want to point out that this lock is made in the USA.
Although the key push lock system is easy to use, it is also designed to be highly resistant toward lock picking, prying, and being drilled out. The location of the cylinder lock also makes it very hard for thieves to access.
- Rustproof and weather resistant
- American made
