- Lubrication of the lever mechanism occasionally may be needed, but it is otherwise low-maintenance.
6. **Legal Compliance**

### **Cons**
1. **Double-Cylinder Limitations**
- **Keyed on both sides** means you must carry a key to enter from the inside if you lock the door from the outside. This can be inconvenient in emergencies (e.g., fire, medical emergency).
- **Not ADA-compliant** for interior doors (though it may be acceptable for exterior doors under certain building codes). If accessibility is a concern, a single-cylinder lever handle may be required.
- **Not ideal for doors without a peephole**, as you cannot see who is outside before unlocking.
2. **Higher Upfront Cost**
- More expensive than basic residential deadbolts (e.g., ANSI Grade 2 or 3). The **GRD.1 commercial-grade** designation adds to the cost, though it justifies the investment for security-conscious buyers.
- Installation may require a **professional locksmith** if you lack experience with deadbolt installation, adding to expenses.
3. **Key Management Challenges**
- **Lost keys can be problematic** since it s a mechanical lock, you must replace the entire cylinder if keys are lost (unlike smart locks, which can be rekeyed electronically).
- **Key duplication requires a locksmith** (unless you have a key blank), which can be inconvenient.
- **Keyway compatibility**: If you have other Schlage locks, you may need to coordinate keying schedules to avoid mismatched keys.
4. **Installation Complexity**
- Requires **precise drilling** for the strike plate and bolt hole. Improper installation can lead to **weak spots in the door frame** or difficulty locking/unlocking.
- If the door is **thin or warped**, the lever may bind or fail to latch properly.
5. **No Smart Features**
- Unlike smart locks, this deadbolt **cannot be controlled remotely**, integrated with home automation systems, or programmed for keyless entry.
- No **audible alerts** for forced entry attempts (unlike some smart locks with sensors).
6. **Potential for Key Duplication Abuse**
- If keys are not properly secured, anyone with access to a key blank can duplicate them, defeating some of the security benefits.
- **Restricted keyways** (e.g., Schlage Keyway #1) help mitigate this but require coordination with locksmiths.
7. **Limited Use Cases**
- **Not ideal for high-security applications** (e.g., vaults, safes, or commercial high-risk areas) where **electronic or high-security mechanical locks** (e.g., Medeco, Abloy) are preferred.
- **Not recommended for doors with frequent high-force impacts** (e.g., garage doors, industrial settings), as the lever mechanism may wear faster.
