❌ Smart Locks Cons

Here are the cons of smart locks to consider before installing one:

🔋 1. Battery Dependency

Smart locks run on batteries, which can die unexpectedly. If not monitored, this could lock you out.

🌐 2. Internet Vulnerability

Many smart locks rely on Wi-Fi or Bluetooth. Connectivity issues or hacking risks can compromise their reliability and security.

📱 3. Technical Glitches

Software bugs, app crashes, or failed firmware updates can render the lock unusable or less secure.

Smart locks are generally more expensive than traditional locks, both in terms of upfront price and potential maintenance.

🧰 5. Installation Challenges

Some models require professional installation or may not fit existing doors without modification.

📶 6. Limited Compatibility

Not all smart locks work with every smart home system or digital assistant (e.g., Alexa, Google Home).

🛠️ 7. Mechanical Failures

Despite being “smart,” many still rely on mechanical parts that can wear out over time or malfunction.

👥 8. Privacy Concerns

Some models collect usage data that could be accessed by manufacturers or third parties, raising privacy issues.
