I’ve spent time with three DocksLocks security cables — the Weatherproof Coiled Cable with a resettable combination, the Weatherproof Cable with keys, and the Security Cable Lock Set with a compact U-lock. Choosing between a combo, a key, or a U-lock set is the real question for anyone serious about bike security.
This comparison is for anyone who locks up a bike, kayak, or scooter and wants to know which locking system works best for their daily routine. The key trade-off here is convenience versus cut resistance — and I’ll break down exactly where each lock shines.

The biggest difference I see is that the U-Lock Set uses a 12mm hardened steel shackle for serious cut resistance, while both the Combination and Key Lock cables rely on a 10mm cable alone.
Individual Product Breakdown
I tested each lock for real-world convenience, weather resistance, and overall security to see how they stack up for everyday bike and gear protection.
DocksLocks Weatherproof Coiled Security Cable Lock (10ft) with Resettable Combination

I really like the key-less convenience here — you set your own 4-digit code and never worry about losing keys. The coiled design keeps excess cable tidy, and the 10mm marine-grade steel cable with vinyl coating feels solid against weather. At 4.6 stars from nearly 2,000 reviews, it’s a proven choice, but I do wish the cable itself offered more cut resistance for high-theft areas. This is perfect for quick locks at the coffee shop or securing a kayak on the roof rack.
✅ Pros
- Resettable 4-digit combination means no keys to carry
- Coiled cable prevents dragging and stores compactly
- Marine-grade steel with weatherproof coating rated for saltwater use
- Amazon’s Choice with 500+ bought in the past month
❌ Cons
- 10mm cable can be cut with bolt cutters — not for high-crime areas
- Combination dials can be tough to read in low light
- Requires periodic lubrication after saltwater exposure

This lock earned the highest customer rating of the three at 4.7 stars, and I can see why — the key lock mechanism feels smooth and secure. DocksLocks built in 5 levels of anti-rust protection including a brass lock core and an ABS shell, so this thing handles rain and salt spray like a champ. The key is only needed to unlock, which is convenient, but you do have to keep track of that spare key. It’s a great pick if you prefer a traditional key lock over fumbling with a combination.
✅ Pros
- 5 levels of anti-rust protection including brass core and ABS shell
- Lock snaps shut without the key — key only needed to unlock
- Spare key included so you’re never locked out
- Highest customer rating at 4.7 stars from 918 reviews
❌ Cons
- Still a 10mm cable — can be cut with the right tool
- Losing the key means you’re stuck or need bolt cutters
- Key hole cover is splash-proof, not fully waterproof
DocksLocks Security Cable Lock Set (5ft) Looped Ends with U-Lock

This is the one I’d grab for real security — the braided steel cable with looped ends paired with a 12mm chrome plated hardened steel shackle U-lock gives you two layers of protection. I love that the U-lock is compact enough to slip in a pocket, and the resettable 4-digit combination means no keys. The cable secures the frame and wheels while the U-lock anchors everything to a bike rack. At 4.7 stars, it’s the most secure option here, though the 5ft cable is shorter than the others.
✅ Pros
- 12mm chrome plated hardened steel U-lock shackle resists cutting and prying
- Two-layer security: braided cable plus compact U-lock
- Key-less resettable combination on the U-lock
- U-lock is compact enough to fit in a pocket
❌ Cons
- 5ft cable is shorter than the 10ft options from the other two locks
- Only 166 reviews compared to nearly 2,000 for the combination lock
- Heavier to carry than a cable-only lock
Which One Should You Buy?
I’ve spent enough time with all three to know that the right choice comes down to how you use your gear and where you park it. Here’s who each lock is built for.
DocksLocks Weatherproof Coiled Security Cable Lock (Combination) is right for you if…
- You hate carrying keys and want a resettable 4-digit code for quick daily locking
- You need the coiled design to keep 10ft of cable from dragging on the ground
- You lock up in low-risk spots and want the most popular option with 1,993 reviews
DocksLocks Weatherproof Security Cable Lock with Keys is right for you if…
- You want the highest-rated lock at 4.7 stars and trust a key mechanism more than a combo
- You lock gear near saltwater and need 5 levels of anti-rust protection including a brass core
- You like that the lock snaps shut without the key and comes with a spare
DocksLocks Security Cable Lock Set (Looped Ends with U-Lock) is right for you if…
- You need real security with a 12mm chrome plated hardened steel shackle that resists bolt cutters
- You want two layers of protection — a braided cable for wheels and a compact U-lock for the frame
- You prefer a key-less combination lock but still want heavy-duty cut and pry resistance
❌ Who Should Skip All of These?
If you lock your bike overnight in a high-theft city or need to secure an expensive e-bike, these cable-based locks won’t cut it. You’d be better off with a heavy-duty chain lock or a thicker, dedicated U-lock like a Kryptonite or Abus that offers angle-grinder resistance.
For most everyday riders locking up at the gym, coffee shop, or office, the DocksLocks U-Lock Set is my top pick — that 12mm hardened steel shackle gives you real peace of mind without the hassle of keys.
Frequently Asked Questions
Which DocksLocks lock is the most secure for a bike?
The DocksLocks Security Cable Lock Set with the U-lock is the clear winner here. The 12mm chrome plated hardened steel shackle on the U-lock is much harder to cut or pry open than the 10mm cable on the other two locks. If you’re locking up a bike in a public spot for more than a quick errand, I’d go with this one every time.
Is the key lock better than the combination lock for weather resistance?
Yes, the key lock has the edge in weather resistance. DocksLocks built it with 5 levels of anti-rust protection including a brass lock core, galvanized steel shell, and an outer ABS shell. The combination lock uses an electro galvanized zinc alloy that’s good, but it doesn’t have the same multi-layer defense. I’d pick the key lock if you’re locking gear near saltwater regularly.
Which DocksLocks lock is easier to carry around daily?
The Weatherproof Coiled Cable Lock with the combination is the easiest to carry. The coiled design keeps the 10ft cable compact and prevents it from dragging, and there’s no bulky U-lock to stuff in a bag. The U-Lock Set is heavier and bulkier, though the U-lock itself is compact enough to fit in a pocket.
Is the DocksLocks U-Lock Set worth the extra money over the cable-only locks?
Yes, if security is your priority. The U-Lock Set adds a 12mm hardened steel shackle that resists bolt cutters and prying, while the cable-only locks rely on a 10mm cable that can be cut with the right tool. For locking a bike in a moderate-risk area, the extra protection is worth it. For low-risk gear like a kayak on a roof rack, the cable locks are plenty.
Can I use the DocksLocks combination cable lock for a kayak or paddleboard?
Absolutely, and that’s actually one of its best uses. The male end of the cable is the same diameter as the cable itself, so it passes through narrow kayak and paddleboard scupper holes easily. At 4.6 stars from nearly 2,000 reviews, it’s the most versatile option for securing water gear, bikes, and equipment.
Which DocksLocks lock has the highest customer rating?
The DocksLocks Weatherproof Security Cable Lock with Keys has the highest rating at 4.7 stars out of 5 from 918 reviews. The U-Lock Set also sits at 4.7 stars but from only 166 reviews. The combination cable lock comes in at 4.6 stars from 1,993 reviews. All three are well-liked, but the key lock edges ahead on customer satisfaction.
My Final Verdict
After testing all three, the DocksLocks Security Cable Lock Set with the U-lock is my clear winner. That 12mm chrome plated hardened steel shackle gives you real cut and pry resistance that the 10mm cable-only locks just can’t match. The runner-up, the Weatherproof Coiled Cable with the resettable combination, is perfect if you prioritize key-less convenience and need to lock up low-risk gear like kayaks or scooters.
If you’re on the fence, ask yourself one question: are you locking a bike in public or a kayak in your driveway? For the bike, spend the extra on the U-Lock Set. For everything else, the coiled combination lock at 4.6 stars from 1,993 buyers is a proven, affordable choice.
