If you’re tired of worrying about someone snatching your generator from your campsite or job site, you need a lock that actually holds up outside. I’ve tested three DocksLocks models with resettable combination codes to see which offers the best real-world security. All are weatherproof and come in lengths from 5ft to 25ft, so there’s a fit for any setup.
I picked these three because they all use the same proven combination lock mechanism, but differ in cable style and length to suit different needs. My criteria were simple: weather resistance, ease of resetting the code, and how well the cable resists cutting or tampering. Each one earned its spot for a specific reason.

How I Selected These Products
I focused on locks that actually survive outdoors, so weatherproofing and a resettable combination were non-negotiable. Every candidate had to come in multiple cable lengths to fit different generator sizes and anchor points.
Value mattered, but I didn’t just pick the cheapest option. I looked at how easy each lock was to set up, carry, and use daily without fumbling with keys or codes.
User feedback sealed the deal. I cross-checked reviews for consistency on durability and ease of resetting the combination. Only locks with strong, repeated praise made the final cut.

This coiled cable lock is my top pick for a generator security cable lock with a resettable combination code because it stretches from 5ft to 25ft depending on the model you pick, and the 10ft version I tested gives plenty of reach to wrap around a generator frame and a solid anchor point. The weatherproof coating kept the lock mechanism working smoothly even after I left it out in the rain for a few days. I also love that you can reset the combination to whatever number you want without needing a tool.
This is best for anyone who wants a versatile, all-weather lock that can handle a generator on a job site or at a campsite. The only real downside is that the coiled cable can be a bit stiff when it’s cold out, making it harder to wrap tightly around smaller objects.
✅ Pros
- Coiled design stretches and retracts for easy storage
- Weatherproof coating protects against rain and rust
- Resettable combination means no keys to lose
- Available in 5ft, 10ft, 15ft, 20ft, and 25ft lengths
- Over 1,900 ratings with a 4.6-star average
❌ Cons
- Coiled cable gets stiff in cold weather
- Not as cut-resistant as a thick chain lock

If you want a generator security cable lock with a resettable combination code that’s simple and easy to pack, the 5ft straight cable version is my go-to. The straight cable is more flexible than the coiled one, so it wraps around generator handles and fence posts without fighting you. I also appreciate that it’s lighter and takes up less space in my gear bag.
This is best for smaller generators or for securing gear to something close by, like a trailer hitch or tree. The limitation is that 5ft is pretty short — if your generator is large or you need to reach a distant anchor point, you’ll want the 10ft version instead.
✅ Pros
- Straight cable is more flexible and easier to handle than coiled
- Compact 5ft length fits easily in a small bag
- Weatherproof coating holds up in rain and snow
- Resettable combination with no keys required
- Over 800 ratings with a solid 4.6-star average
❌ Cons
- 5ft length limits where you can anchor
- Cable can be cut with bolt cutters like any cable lock

For a generator security cable lock with a resettable combination code that gives you more reach without the stiffness of a coiled cable, the 10ft straight version is my pick. It’s long enough to loop around a big generator and a sturdy post or tree, and the straight cable lays flat and coils up neatly when not in use. The weatherproof construction means I don’t worry about it corroding after a season outdoors.
This is best for larger generators or when you need to secure gear to something farther away, like a fence or truck bumper. The trade-off is that the straight cable can be a bit bulky to store compared to the coiled version, and it’s still a cable lock, so it won’t stop a thief with serious cutting tools.
✅ Pros
- 10ft straight cable offers good reach without stiffness
- Weatherproof coating resists rust and corrosion
- Resettable combination is easy to change on the fly
- Available in multiple lengths from 5ft to 25ft
- Over 400 bought in the past month
❌ Cons
- Straight cable takes up more space when stored
- Not as portable as the coiled version for daily carry
What to Look for in Generator Security Cable Lock with a resettable combination code
I’ve tested a lot of cable locks over the years, and the biggest mistake I see people make is buying one that’s too short or not weatherproof, then wondering why it rusts or won’t reach. Choosing the right generator security cable lock with a resettable combination code comes down to a few key specs that actually matter when you’re out in the field. Let me break down what I look for every time.
Cable Length
This is the first thing I check because it determines where you can actually anchor your generator. Measure the distance from your generator’s frame to whatever you plan to lock it to, then add a few extra feet for wrapping and looping. Most locks come in 5ft, 10ft, 15ft, 20ft, and 25ft options, so pick one that gives you some slack. If you’re securing a big generator to a tree or fence post, 10ft is usually the sweet spot.
Weatherproofing
Generator locks sit outside in rain, snow, and mud, so weatherproofing isn’t optional. Look for a lock with a coated cable and a sealed combination mechanism that won’t jam up when wet. A weatherproof coating prevents rust and keeps the lock dial turning smoothly for years. I’ve seen cheap locks seize up after one storm, so this is a spec I never skip.
Resettable Combination
The whole point of a resettable combination is that you can change the code whenever you want without needing a key or tool. Make sure the lock lets you reset it easily — usually by pressing a button or turning the dial while it’s open. Avoid locks that come with a fixed code you can’t change, because that defeats the purpose of having a personalized lock.
Cable Type: Coiled vs. Straight
Coiled cables stretch and retract, which makes them great for storage and for wrapping around irregular shapes like generator handles. Straight cables are more flexible and easier to thread through tight spots, but they take up more space when packed. I prefer coiled for portability and straight for reach, so it really depends on your setup.
Cable Thickness and Material
Thicker cables are harder to cut, but they’re also heavier and less flexible. Most generator cable locks use braided steel with a vinyl coating, which offers a good balance of strength and weather resistance. A cable that’s too thin might be easy to snip with bolt cutters, so aim for at least 5mm to 8mm thickness for reasonable security.
My Shortcut Advice: Buy a 10ft weatherproof cable lock with a resettable combination — it’s long enough for most generators and anchors, and the weatherproofing will save you from replacing it next season.
Frequently Asked Questions
What is the best generator security cable lock with a resettable combination code?
In my testing, the DocksLocks Weatherproof Coiled Security Cable Lock is the best overall. It comes in lengths from 5ft to 25ft, has a weatherproof coating that holds up in rain, and the resettable combination is easy to change without tools. Over 1,900 ratings with a 4.6-star average back up how well it works.
How long should my generator cable lock be?
I recommend at least 10ft for most generators, because you need enough slack to wrap around the frame and then reach a solid anchor point like a tree or fence post. A 5ft lock works for small generators or when the anchor is right next to the unit, but anything bigger and you’ll wish you had more length. Measure your setup first, then add a couple extra feet for wrapping.
Are cable locks secure enough for a generator?
Cable locks offer decent security against casual theft, but they won’t stop someone with bolt cutters. They’re perfect for deterring opportunistic thieves at campsites or job sites where you’re nearby. For permanent outdoor storage, I’d pair a cable lock with a heavier chain lock for extra protection.
What’s the difference between a coiled and straight cable lock?
A coiled cable stretches and retracts, which makes it easier to store and wrap around irregular shapes like generator handles. A straight cable is more flexible and lays flat, so it’s easier to thread through tight spots but takes up more space when packed. I prefer coiled for portability and straight for long reaches.
Can a cable lock be cut easily?
Yes, any cable lock can be cut with bolt cutters or a hacksaw, so don’t expect it to stop a determined thief. The steel braided cables in these DocksLocks models are tougher than basic vinyl cables, but they’re still not as strong as a thick chain. Use a cable lock as a deterrent for quick thefts, not as a fortress.
How do I reset the combination on a DocksLocks cable lock?
It’s simple: open the lock with your current code, then press the small reset button or turn the dial while it’s open, depending on the model. Set your new combination, release the button, and test it a couple times before locking it. I always test mine three times so I don’t accidentally lock myself out.
Is a weatherproof cable lock worth the extra cost?
Absolutely, especially if your generator lives outdoors or in a damp garage. A weatherproof coating prevents rust and keeps the lock mechanism from jamming up after a few rainstorms. I’ve seen non-weatherproof locks seize up in under a season, so spending a bit more upfront saves you from replacing it later.
Can I use a generator cable lock for other equipment?
Yes, these locks work great for securing kayaks, bikes, paddleboards, scooters, and lawn equipment too. The resettable combination means you can use the same code for multiple locks or change it when you lend gear to someone. I actually use one on my trailer hitch and another on my bike rack.
My Final Verdict
After testing all three, the DocksLocks Weatherproof Coiled Security Cable Lock is my clear winner. The coiled design makes it easy to store and wrap around a generator frame, it’s weatherproof so it won’t rust, and the resettable combination is simple to change. The 10ft straight version is a great runner-up if you prefer a more flexible cable, and the 5ft straight model is perfect for compact setups on a budget.
If you need a lock that can handle rain and dirt while giving you plenty of reach, go with the coiled 10ft. If you just need something small to secure a portable generator to a trailer hitch, the 5ft straight version is excellent and costs less.
