For **high-security needs (e.g., safes, vaults, or high-risk commercial doors)**, a higher-grade lock (e.g., with a **5-pin tumbler or electronic backup**) may be necessary.

6. **Not Suitable for High-Security Applications** If you require **military-grade security (e.g., for safes, government buildings, or high-value assets)**, this lock is **not sufficient**. For such cases, **high-security cores (e.g., Abloy Protec2, Mul-T-Lock, or electronic locks with backup mechanisms)** are recommended.
