Discover how to power your smart door lock reliably with the LOQED Power Kit. This buying guide covers power needs, best Shelly accessories, installation tips, and backup strategies.
Smart door locks offer convenience and security, but their Achilles' heel is often power. Batteries die at the worst moment, and wired solutions can be complex. The LOQED Power Kit addresses this by providing a continuous, low-voltage power supply to your smart lock, eliminating the need for frequent battery changes. However, choosing the right components and installation method is key to a reliable setup.

In this buying guide, we’ll explore the power requirements of smart door locks, how the LOQED Power Kit works, and which Shelly accessories can enhance your system. Whether you’re retrofitting an existing lock or building a new smart entry, this guide will help you make informed decisions for a battery-free, always-on door lock.
Understanding Smart Lock Power Needs
Smart locks typically run on 4-6 AA batteries or a built-in rechargeable pack, lasting 3-12 months depending on usage. Frequent locking/unlocking, Wi-Fi communication, and motorized deadbolts consume more power. The LOQED Power Kit replaces the batteries with a constant 12V DC supply, bypassing the battery compartment entirely. This not only saves money on batteries but also prevents lockout due to dead batteries.
Key considerations include the lock’s voltage and current draw. Most smart locks operate at 6V or 12V, with a peak current up to 2A during motor operation. The LOQED Power Kit provides regulated 12V output, but you may need additional components to step down voltage or monitor consumption. This is where intelligent relays and energy meters come into play.
- Check your lock's voltage rating before choosing a power kit.
- If your lock uses 6V, a step-down converter or a 6V LOQED variant is required.
- Consider power consumption monitoring to spot unusual drain early.
LOQED Power Kit: What It Offers and What You Need
The LOQED Power Kit is designed as a drop-in replacement for battery-powered smart locks. It connects to a standard 12V power adapter or a central power distribution system. The kit includes a specialized connector that mimics the battery terminals, ensuring seamless integration with the lock’s electronics. While the kit handles basic power delivery, adding smart components allows you to cut power remotely, monitor energy use, or integrate with home automation.
For instance, pairing the kit with a Shelly Plus 2PM List gives you automatic power-off capabilities and real-time power statistics. This relay can be triggered by a smart lock status or a schedule, adding an extra layer of control. Similarly, the Shelly EM Mini Gen4 2-pack can measure the exact energy consumed by the lock, helping you optimize battery backup runtime.
- Use the Shelly Plus 2PM List to enable remote power cycling of your lock in case of a malfunction.
- With the Shelly EM Mini Gen4 2-pack, you can log energy usage and receive alerts when consumption spikes.
- The LOQED Power Kit itself does not include monitoring; add smart accessories for full visibility.
Selecting the Right Shelly Accessories for Your LOQED Power Setup
To truly maximize your smart door lock power supply, consider a few key additional components. The Shelly Plus Plug S List is a compact smart plug that can control the power adapter feeding the LOQED kit. This gives you the ability to cut power to the lock remotely or on a schedule—useful for temporary disarming or maintenance. Its energy monitoring feature also lets you track the lock’s consumption over time.
If you prefer a hardwired solution, the Shelly Plus 2PM List can be installed inside a distribution box, offering two independent relay channels. Use one for the lock’s main power and the second for a backup UPS circuit. Additionally, the Shelly 120A Current Transf. Pro 3EM is overkill for a single lock, but ideal if you monitor multiple locks or other devices in a multi-unit building. For most home setups, the smaller current transformers from the Gen4 series are more suitable.
- For temporary remote cutoff: Shelly Plus Plug S List is easiest to install.
- For permanent wired installation: Shelly Plus 2PM List is more discreet and reliable.
- Energy monitoring with Shelly EM Mini Gen4 2-pack helps detect battery charge drain patterns.
Installation Tips for a Reliable Battery-Free Door Lock
Installing the LOQED Power Kit with Shelly accessories requires attention to safety and wiring. Always disconnect the lock’s battery compartment and confirm the polarity of the LOQED connector. Run the low-voltage cable through a door hinge or frame channel to keep it hidden. For the smart relay, ensure it is rated for the lock’s surge current (typically up to 3A), which most Shelly products handle easily.
Place the relay inside a weatherproof junction box if mounted outdoors, or inside the door frame if using a wired system. The Shelly 1-Channel Decoupler 230V is not needed here since the LOQED kit uses low-voltage DC, but it can be useful if you want to isolate a mains-powered adapter from smart control. Test the lock’s functionality with the power kit before closing everything up.
- Use a multimeter to verify the LOQED kit output matches your lock’s voltage before connecting.
- If using a Shelly relay in the door cavity, choose a model with a small form factor like the Shelly Plus 1PM.
- Label all cables for easy troubleshooting later.
Power Backup Strategies for Your Smart Lock
Even with a constant power supply, outages can occur. The LOQED Power Kit does not include a built-in battery, so you need an external UPS or backup plan. A simple approach is to connect the power adapter to an uninterruptible power supply (UPS) designed for home networking gear. Alternatively, integrate a Shelly Plus Plug S List with a small 12V backup battery that automatically kicks in when mains fail.
For maximum uptime, install a Shelly EM Mini Gen4 2-pack on the lock’s power line to monitor for undervoltage conditions. The relay can then trigger an alert or switch to backup power via a second relay. This setup ensures you never get locked out, even during extended blackouts. Remember to test the backup system periodically.
- A 12V 7Ah lead-acid battery can power a typical smart lock for several days.
- Use the Shelly Plus Plug S List to cut power to the lock automatically after a set time to save backup battery.
- Configure notifications in your smart home platform for low voltage or power loss.
Choosing the right power solution for your smart door lock is a worthwhile investment in reliability and convenience. The LOQED Power Kit eliminates battery anxiety, and by adding Shelly accessories like the Shelly Plus 2PM List or Shelly EM Mini Gen4 2-pack, you gain monitoring, control, and peace of mind. Whether you opt for a simple plug-in setup or a fully integrated system, the key is to plan for your lock’s specific power needs and include a backup strategy. For a seamless start, explore the LOQED Power Kit compatible accessories at Shelly Europe and build a lock that never lets you down.
