Often, unlinking and relinking the smart lock skill or service in the Alexa/Google Home app can resolve connectivity issues.
• Lock Battery Drains Quickly: Frequent use, poor Wi-Fi signal (causing the lock to constantly search for a connection), or cold weather can all shorten battery life. Ensure your Wi-Fi router is within a reasonable range of the lock. Consider using high-quality alkaline or lithium batteries, as recommended by the manufacturer. If drainage is excessively fast, it might indicate a hardware issue requiring professional attention.
• Smart Lock is “Jammed” or Not Operating Smoothly: This can often be due to misalignment of the door or strike plate, or internal mechanical issues. Check if your door closes and latches smoothly without the smart lock. If there’s resistance, you might need to adjust the door frame or the strike plate. Never force a smart lock; if the issue persists after checking alignment, it’s best to contact customer support.
• Concerns About Hacking or Security Breaches: While smart locks are generally very secure, no technology is entirely immune. Ensure your Wi-Fi network is secured with a strong password. Always keep your smart lock’s firmware updated to patch any known vulnerabilities. Use complex passcodes and unique voice PINs for voice unlocking. Opt for locks from reputable brands that prioritize encryption and security in their design.
