---

### **Pros of the Kwikset 660-15S STRKP SmartKey Deadbolt**

1. **SmartKey Technology**

The SmartKey system allows homeowners to rekey the lock without needing a locksmith. This is particularly useful if you move into a new home or want to change keys without the hassle of traditional rekeying. The system uses a unique key that can be programmed to work with the lock, and spare keys can be made on-site.

2. **Compatibility with Smart Home Ecosystems**

The Kwikset 660 series is compatible with major smart home platforms like Amazon Alexa, Google Assistant, and Apple HomeKit. This means you can control the lock via voice commands, smartphone apps, or smart home automation routines. For example, you can set up the lock to automatically engage when you leave the house or grant temporary access to guests.

3. **Durability and Security**

Kwikset is a well-known brand with a reputation for quality and durability. The 660 series features a solid steel construction, which provides good resistance to forced entry. It also includes a Grade 1 security rating, which is the highest rating for residential deadbolts, indicating strong resistance to picking, drilling, and other common attack methods. The lock also has a reinforced strike plate for added security.

4. **Easy Installation**

The Kwikset 660 series is designed for straightforward installation, even for those with minimal DIY experience. The lock comes with detailed instructions, and Kwikset offers a tool-free installation option for some models. Most users can install it in under an hour, though some may need basic tools like a drill and screwdriver.

5. **User-Friendly App Control**

The Kwikset Home app (or integration with other smart home apps) allows you to monitor and control the lock remotely. You can lock or unlock the door from anywhere, receive notifications when the door is opened or closed, and set up schedules for automatic locking/unlocking. The app also provides activity logs, which can be useful for tracking who has accessed the door.

6. **Temporary Access Codes**

One of the most convenient features of smart locks is the ability to grant temporary access codes to guests, delivery personnel, or service providers. You can set time-limited codes that automatically expire, reducing the risk of lost keys or unauthorized access. This feature is especially useful for renters or homeowners who frequently host guests.

7. **Compatibility with Existing Keys**

The SmartKey system allows you to use your existing keys with the new lock, provided they are compatible with the SmartKey technology. This means you don t have to replace all your keys at once, which can save time and money.

8. **Aesthetic Appeal**

The Kwikset 660 series comes in a variety of finishes, including brushed nickel, oil rubbed bronze, and satin stainless steel, which can complement most door styles and home decor. The design is sleek and modern, blending well with both traditional and contemporary interiors.

9. **Low Maintenance**

Unlike traditional locks that may require lubrication or occasional adjustments, smart locks like the Kwikset 660 are relatively low-maintenance. The main upkeep involves keeping the app updated and occasionally checking the battery (if using a battery-powered model). The STRKP version is typically hardwired, so it doesn t rely on batteries for core functionality.

10. **Integration with Security Systems**

The Kwikset 660 can be integrated with home security systems like ADT, Simplisafe, or others that support smart locks. This allows you to arm or disarm your security system remotely and receive alerts if the lock is tampered with or opened unexpectedly.

### **Cons of the Kwikset 660-15S STRKP SmartKey Deadbolt**

1. **Cost**

The Kwikset 660 series is more expensive than traditional deadbolts. While the upfront cost may be justified by the added features, it can be a significant investment for those on a tight budget. Prices typically range from $200 to $300, depending on the retailer and any additional accessories needed.

2. **Hardwired Dependency (for STRKP Model)**

The STRKP version of the 660 series is hardwired, meaning it requires electrical wiring to function. This can be a drawback if your door doesn t have existing wiring or if you re renting and can t modify the door. While the lock can still be unlocked manually in a power outage, the smart features (like app control) will be disabled until power is restored. Some users may prefer a battery-backed model for redundancy.

3. **Learning Curve for Smart Features**

While the app and voice control are intuitive for tech-savvy users, they may pose a challenge for those who are less familiar with smart home technology. Setting up automation routines, managing user codes, or troubleshooting connectivity issues might require some patience and learning.

4. **Potential for False Positives or Negatives**

Smart locks can sometimes experience connectivity issues, leading to false notifications (e.g., the app showing the door as unlocked when it s actually locked). While rare, these issues can be frustrating and may require troubleshooting or a firmware update to resolve.

5. **Limited Physical Key Access**

Some users prefer the convenience of a physical key as a backup, especially in emergencies. While the SmartKey system allows you to use keys, the process of rekeying or creating new keys can be less convenient than simply turning a key in a traditional lock. Additionally, if the lock is jammed or the app is unresponsive, you might need to rely on a locksmith.

6. **Compatibility Issues with Some Doors**

The Kwikset 660 series is designed to work with standard doors, but there may be compatibility issues with older doors, doors with non-standard hardware, or doors that are not properly aligned. Installation can be more challenging if the door frame or strike plate is damaged or poorly installed, potentially requiring additional tools or adjustments.

7. **Dependence on Internet Connectivity**

To use the full range of smart features (remote control, automation, notifications), you need a stable internet connection. If your Wi-Fi is unreliable or you re in an area with poor connectivity, some features may not work as expected. While the lock itself may still function locally, smart features will be limited.

8. **Potential for Hacking or Security Risks**

Like all smart devices, the Kwikset 660 is not entirely immune to hacking or security breaches. While Kwikset employs encryption and security measures to protect against unauthorized access, there is always a risk if the lock is not properly secured (e.g., using weak passwords or default settings). It s important to follow best practices for securing your smart lock, such as enabling two-factor authentication and regularly updating the firmware.

9. **Battery Backup Limitations (for STRKP)**

The STRKP model is hardwired, but if the wiring is damaged or the power supply fails, the lock may not function at all. Unlike battery-backed smart locks, there is no backup power source to ensure the lock remains operational during outages. This could be a concern for users in areas prone to power surges or outages.

10. **Customer Support and Warranty Concerns**

While Kwikset generally offers good customer support, some users have reported issues with warranty claims or slow response times for technical problems. It s important to review the warranty details and customer reviews before purchasing to ensure the product meets your expectations.

---

### **Conclusion**

The Kwikset 660-15S STRKP SmartKey deadbolt is a robust and feature-rich smart lock that offers significant advantages in terms of convenience, security, and smart home integration. Its SmartKey technology, compatibility with major smart platforms, and Grade 1 security rating make it a strong choice for homeowners looking to upgrade their door security. The ease of installation and user-friendly app control further enhance its appeal, particularly for those who value automation and remote access.

However, the higher cost, hardwired dependency, and potential learning curve for smart features may deter some users. Additionally, reliance on internet connectivity and the risk of technical issues (while rare) are factors to consider. For those who prioritize smart home integration, temporary access codes, and high-security standards, the Kwikset 660 is an excellent investment. For others who prefer simplicity, a physical key backup, or battery-powered reliability, alternatives like the Kwikset 620 series (battery-powered) or traditional smart locks may be worth exploring.
