### **Cons of the Kwikset SmartKey CP991TNL-15S**
1. **Zigbee Dependency (No Built-in Wi-Fi or BLE)**
Unlike some smart locks (e.g., August or Schlage Encode), this deadbolt **does not have built-in Wi-Fi or Bluetooth**. It requires a **Zigbee hub** (such as the **Kwikset Kevo Hub, SmartThings, or Amazon Echo Plus**) to function with smart home ecosystems. This adds an extra cost and complexity for some users.
2. **Limited Local Control Without a Hub**
If you don t have a Zigbee hub, you ll need to rely on **physical keys or the keypad** for access. This reduces the convenience of true "smart" functionality.
3. **Battery Life Concerns**
While the deadbolt itself uses AA batteries, the **Zigbee hub may require its own power source** (e.g., hardwired or battery-powered). If the hub fails, the entire system could go offline. Additionally, battery life for the deadbolt itself may vary, and users must remember to replace them periodically.
4. **No Built-in Video or Camera**
Unlike some high-end smart locks (e.g., Yale Assure Lock), this deadbolt **does not include a camera or video doorbell integration**. If you want video monitoring, you ll need a separate device.
5. **Learning Curve for Smart Features**
Setting up and troubleshooting smart home integrations (especially with Alexa or Google Assistant) can be **frustrating for less tech-savvy users**. Some users report issues with app connectivity or voice control.
6. **Not Fully Weatherproof**
While the deadbolt itself is durable, **extreme weather conditions** (e.g., heavy rain or snow) could potentially affect the keypad or electronic components over time. It s best installed in a sheltered area.
7. **Compatibility Issues with Some Smart Home Systems**
Some users have reported **incompatibility with certain smart home platforms** or hubs, leading to connectivity problems. Always check compatibility before purchasing.
8. **No Built-in Alarm System**
Unlike locks with **motion sensors or tamper alerts**, the CP991TNL-15S does not notify you if someone attempts to pick or force the lock. This is a drawback for security-conscious users.
9. **Cost of Additional Accessories**
To fully utilize smart features, you may need to purchase:- A **Zigbee hub** (e.g., Kwikset Kevo Hub, SmartThings, or Amazon Echo Plus).
- A **SmartKey reprogramming tool** ( $20) for rekeying.
- Extra **AA batteries** for backup power.
10. **Not Ideal for High-Security Needs**
While it meets **Grade 1 security standards**, it may not be as robust as **hardwired smart locks with military-grade encryption** (e.g., Schlage Encode or Yale Assure).

It offers **flexibility with keyless entry, smart home integration, and easy rekeying**, making it great for renters or those who prefer multiple access methods.

If you re willing to invest in a hub and enjoy DIY projects, this deadbolt provides **excellent security and convenience**.
For those who prioritize **simplicity and full smart home integration without extra hardware**, alternatives like the **August Smart Lock Pro** (Wi-Fi/BLE) or **Schlage Encode Plus** (hardwired with built-in Wi-Fi) might be better.
