### Pros and Cons of buying a Lockly Guard PGD679LZSN (Z-Wave Smart Latch)
#### **Pros:**1. **Smart Home Integration** The Lockly Guard PGD679LZSN is a Z-Wave smart latch, meaning it can be controlled and automated through popular smart home platforms like Home Assistant, Samsung SmartThings, Apple HomeKit, and others. This allows for seamless integration with other smart devices, such as lights, thermostats, and security cameras, enabling automated routines like locking doors at specific times or triggering alerts when the door is opened.
2. **Keyless Entry** The latch supports keyless entry via a built-in keypad, allowing users to input a code to unlock the door. This eliminates the need for physical keys, reducing the risk of lost or stolen keys. Some models also support temporary access codes for guests or service providers.
3. **Remote Access and Control** With Z-Wave compatibility, you can monitor and control the latch remotely via a smartphone app. This means you can lock or unlock the door from anywhere, check the door s status, and receive notifications when the door is opened or closed.
4. **Enhanced Security** The smart latch often includes features like auto-locking, which can help prevent doors from being left unlocked accidentally. Some models also support two-factor authentication or integration with biometric systems for added security.
5. **Compatibility with Existing Locks** The PGD679LZSN is designed to replace traditional deadbolts, meaning it can be installed on most standard doors without requiring extensive modifications. It is compatible with many existing door hardware setups, making it a convenient upgrade.
6. **Energy Efficiency** By integrating with smart home systems, you can automate door locking based on factors like time of day or presence detection (via sensors), which can help reduce energy waste by ensuring doors are locked when not in use.
7. **Durability and Weather Resistance** The latch is typically built to withstand outdoor conditions, making it suitable for use on exterior doors. It is often made from durable materials like stainless steel or aluminum, which resist corrosion and wear.
8. **Customizable Access Levels** Many smart latch systems allow you to set different access codes with varying permissions (e.g., one-time use codes, time-limited access, or restricted hours). This is particularly useful for managing access for family members, guests, or service providers.
9. **Integration with Security Systems** The latch can be linked to alarm systems, so opening the door without authorization can trigger an alert or activate a security response. This adds an extra layer of protection for your home.
10. **Future-Proofing** Z-Wave technology is widely adopted and continues to evolve, ensuring that your smart latch will remain compatible with future smart home devices and updates.

#### **Cons:**1. **Initial Cost** Smart latches like the Lockly Guard PGD679LZSN are more expensive than traditional deadbolts. The upfront cost may be a barrier for some users, especially if they are upgrading multiple locks or need additional hardware like sensors or bridges for full functionality.
2. **Complex Installation** While the latch itself is designed to replace a standard deadbolt, installation can be more complex than a basic lock. It may require drilling new holes for the latch mechanism, wiring for power (if battery-powered options are not preferred), and proper alignment with the strike plate. Some users may need to hire a professional locksmith, adding to the cost.
3. **Dependence on Smart Home Ecosystem** The full functionality of the latch relies on a working smart home hub or gateway (e.g., Samsung SmartThings, Home Assistant server, or Apple HomeKit). If your hub fails or is incompatible with the latch, you may lose remote access and automation features. Some users may also need to purchase additional hardware like a Z-Wave hub or bridge, depending on their setup.
4. **Battery Dependency (if applicable)** While some smart latches are hardwired, others rely on batteries for power. If the battery dies, the latch may not function, and you could find yourself locked out of your home. Regular battery checks and replacements are necessary to avoid this issue.
5. **Learning Curve** Setting up and configuring a smart latch, especially for users unfamiliar with smart home technology, can be overwhelming. It may require time to learn how to use the app, set up access codes, and troubleshoot connectivity issues.
6. **Potential for False Positives/Negatives** Smart latches can sometimes experience connectivity issues or false alerts (e.g., reporting the door as unlocked when it is actually locked). This can lead to unnecessary stress or inconvenience if notifications are not accurate.
7. **Limited Physical Security in Power Outages** In the event of a power outage or hub failure, some smart latches may lose their ability to lock or unlock remotely. While many still function manually, this could be a concern for users who rely heavily on automation.
8. **Compatibility Issues** Not all smart home platforms or hubs support every feature of the Lockly Guard latch. Some users may find that certain automation or integration features are not available depending on their ecosystem. Always verify compatibility with your specific hub or platform before purchase.
9. **Potential for Hacking or Security Risks** Like all connected devices, smart latches are vulnerable to hacking if not properly secured. Weak passwords, unpatched firmware, or poor network security can expose the latch to unauthorized access. Users must take steps to secure their smart home network to mitigate these risks.
10. **Maintenance and Updates** Smart devices require occasional firmware updates to maintain security and functionality. If the manufacturer stops supporting the device or updates are not provided, the latch may become less reliable over time.

### **Conclusion:**The Lockly Guard PGD679LZSN is a robust and feature-rich smart latch that offers significant advantages for users looking to enhance their home s security, convenience, and smart home capabilities. Its Z-Wave compatibility, keyless entry, remote access, and integration with other smart devices make it a strong choice for tech-savvy homeowners. However, the higher cost, potential installation challenges, and reliance on a functional smart home ecosystem are drawbacks that should be carefully considered.
For users who prioritize security, automation, and the ability to manage access remotely, the Lockly Guard PGD679LZSN is a worthwhile investment. It is particularly well-suited for homes with existing smart home setups or those planning to expand their automation. On the other hand, users who prefer simplicity, minimal upfront costs, or do not intend to integrate with a smart home system may find traditional locks more practical.

- **Smart Deadbolts:** If you prefer a more traditional look, a smart deadbolt (e.g., Schlage Encode or Yale Assure) may be a better fit, though it requires a separate strike plate.
