2. **Key Management Issues** Losing or misplacing keys can be a hassle, especially if multiple people (e.g., family members or delivery personnel) need access. There s no built-in key recovery system.

3. **Potential for Wear Over Time** While durable, frequent use or exposure to harsh weather can eventually lead to wear on the lock mechanism, requiring eventual replacement.

4. **No Smart Features** Unlike modern smart locks, this model cannot be integrated with home automation systems, keyless entry, or remote access controls.

5. **Dependence on Physical Keys** If keys are stolen or duplicated without authorization, security risks increase. There s no digital backup or alternative access method.

6. **Installation Limitations** Some users may find the installation process slightly tricky if they lack basic tool skills, though it s generally straightforward for most people.

7. **No Warranty on All Parts** While Salsbury offers warranties, they may not cover all potential issues (e.g., wear from misuse), leaving users responsible for repairs in some cases.
