It sounds like you're referring to a specific type of lock, possibly a "Sonica 67mm double lock" with four keys. This could be a high-security lock designed for enhanced protection, with a double locking mechanism that provides extra security compared to standard locks.Here's a general overview of what you might expect from such a lock:Size: The 67mm measurement likely refers to the overall size of the lock body, which can be an important factor for fitting into specific doors or security fixtures.Double Locking Mechanism: This means the lock engages at two points for added security. This can make it more resistant to forced entry compared to single-lock mechanisms.Keys: The lock comes with four keys, which is often the case with high-security locks to ensure that multiple people can access the lock, but it also provides extra keys in case one is lost.Brand and Model: "Sonica" might be a brand name, and "67mm" could be the model number or a specification detail.Size: 67mm overall lock body.Locking Mechanism: Double lock for enhanced security.Keys Included: Comes with 4 keys.Brand: Sonica.Model: 67mm (indicates size or model number).If you need more specific details or help with this lock, let me know!Sonica67mm lockDouble lockHigh-security lock4 keysLocking mechanismKeyed alikeSecurity lockLock cylinderDoor lockLockLock and keykey4key lockdouble lock
