How does the high-security lock core in chain locks prevent theft for bikes and motorcycles?

1. Anti-technical unlocking design
Complex lock core structure: C-level lock core adopts double-row pins, blade structure, curved groove and other designs, which greatly increases the difficulty of technical unlocking, and the anti-technical unlocking time can reach more than 270 minutes.
Anti-pick and anti-drill technology: Some lock cores are equipped with anti-pick and anti-drill lock cores to prevent thieves from using tools such as tin foil and master keys to crack.

2. Anti-violent destruction ability
High-strength material: The lock core is usually made of copper or alloy, with manganese steel chain, which can resist violent destruction such as hydraulic shears and hammering.

3. Physical blocking and deterrence
Chain reinforcement: The chain links of high-security chain locks are thick (such as 12mm manganese steel chain), covered with anti-cutting protective layer, which increases the difficulty of cutting.
Lock body design: The lock head and lock shell are made of anti-drilling alloy or thickened design to prevent violent prying.

4. Usage suggestions
Fixing method: Pass the chain lock through the wheel, frame and fixed objects (such as railings) at the same time to reduce the chance of theft.
Regular maintenance: Lubricate the lock cylinder and clean the rust on the chain to extend the service life
