Cable & Chain Locks

Choose based on what you need to secure and where: heavier chains (hardened steel, thicker links) or thicker braided cables resist cutting better for high-risk areas; lighter, flexible cables are easier to transport for low-risk use. Consider lock type (key vs. combination), shackle diameter or cable thickness, length to fit the items, and any mounting or carry features

Look for hardened steel chains and sleeves that resist bolt cutters, and braided or multi-strand steel cables with protective coatings to reduce abrasion. Some products list security ratings from independent test bodies—higher ratings generally indicate better resistance to cutting, picking, and impact

Key locks typically offer slightly higher tamper resistance but require carrying a key or using a key retention solution; combination locks avoid keys and are convenient for shared use or frequent access but may be more vulnerable to guessing or manipulation if low quality. Choose based on whether convenience or resistance to forced entry is the priority

For bikes: 4–6 foot lengths are common to loop around frame and fixed object; thickness 10–16 mm for chains or 8–12 mm for braided steel cables provide stronger resistance. For tool chests and gates: longer lengths as needed and thicker/heavier-duty chains (12 mm+) or high-security cables to deter cutting

Keep moving parts lubricated with a lock-appropriate lubricant, wipe off dirt and moisture, store indoors when possible, and check protective coatings for wear; replace any lock with visible corrosion, frayed strands, or damaged mechanisms to maintain security

Yes—features include double-bolting shackles, anti-pick cylinder designs, anti-drill plates, protective sleeves to prevent cutting points, and tamper-resistant link profiles. Also consider whether the lock has mounting hardware or carrying solutions to reduce exposure while in use

Budget, lower-security options can be found under $50; mid-range locks offering better materials and features commonly fall between roughly $50–$150; heavier-duty, specialized chains and high-security locks typically exceed that range. Match spending to the value of the item being protected and the local theft risk
