Under normal use, the LOQED Touch Smart Lock runs for approximately 9–12 months on one set of 8 alkaline batteries. If your batteries drain much faster than that, there are two common causes:
Poor-quality or faulty batteries.
A Touch Display issue. An internal sensor fault in the Touch Display (the outside module) can cause a short circuit that slowly drains the batteries.
Follow the steps below in order. Each step helps you rule out a cause, so you can find the right solution.
Step 1: Check the batteries you are using
Battery quality has a big impact on how long a set lasts.
Alkaline batteries are recommended for the LOQED Touch Smart Lock.
Zinc-carbon batteries (sold by some brands) are not suitable for this lock.
Ni-MH rechargeable batteries (the LOQED Power Kit) are supported, but quality can vary.
What to check
Open the inside of the lock and check that the batteries are not dirty or leaking.
Confirm the batteries are alkaline or Ni-MH rechargeable (Power Kit) – not zinc-carbon.
Insert a new set of good-quality alkaline batteries (preferably a different, well-known brand) to see whether these also drain too fast.
If you are in contact with our support team, please share a photo of the batteries you are currently using.
⚠️ Switching from Ni-MH (Power Kit) to alkaline? After inserting alkaline batteries, change the battery type in the app, otherwise the battery percentage will be inaccurate:
LOQED app → Select your lock → My Lock → Batteries & Charging → Alkaline
What the result means
If battery life improves with the new batteries, the cause was low-quality or faulty batteries. Problem solved.
If the batteries still drain quickly, continue to the next step.
Step 2: Check that the lock runs smoothly
If the door or cylinder does not move smoothly, the motor has to work harder, which uses more battery. This can happen if your door has a multi-point lock, if there is tension on the door, or if the cylinder does not rotate smoothly.
What to check
Temporarily disable Twist Assist in the LOQED app.
Turn the knob by hand. The cylinder should turn smoothly and without resistance.
What the result means
If the cylinder does not move smoothly, the door or lock mechanism may need adjustment. A stiff mechanism increases battery use.
If the cylinder moves smoothly, continue to the next step.
Step 3: Understand the battery percentage
The battery percentage in the LOQED app is an estimate, not an exact measurement, and battery use is not linear. For example, the level may drop 25% over the first 3 months and then another 25% within a single month.
Some batteries work well at first and then drain very quickly near the end of their life. A faster drop towards the end can be normal and does not always indicate a fault.
Step 4: Test for a Touch Display issue
If a fresh set of good-quality alkaline batteries still drains within days or a few weeks, the Touch Display may be causing a short circuit. This test confirms it:
Make sure a new set of good-quality alkaline batteries is installed (from Step 1).
On the inside of the lock, disconnect the Touch Display cable from the motor module.
Note the exact date and time you disconnected the cable, then monitor the battery usage over the following days.
If you are in contact with our support team, tell them the exact time you disconnected the cable so they can help compare the battery usage.
What the result means
If the battery drain stops while the Touch Display is disconnected: the Touch Display needs to be replaced (see options below).
If the batteries still drain quickly even with the Touch Display disconnected: the Touch Display is not the cause. Insert new batteries, record a short video while locking and unlocking the door (the motor sound helps us assess the mechanism), and contact LOQED support so we can investigate further.
Replacing the Touch Display
If the test above shows the Touch Display is causing the drain, you have two options:
Option 1: Within 2 years of purchase (warranty)
If your lock was purchased less than two years ago, the Touch Display is covered by warranty. Contact LOQED support via the live chat in the LOQED app (Menu → Chat support) and upload your invoice or proof of purchase. We will then provide a free replacement coupon code for a new Touch Display.
Option 2: Outside the 2-year warranty
If your lock is older than two years, you can purchase a replacement at shelly.com/products/loqed-touch-display. The newer display has improved quality and is fully backwards compatible with the LOQED Touch Smart Lock.
For instructions on fitting the new part, see How to replace your LOQED Touch Display.
Tip: the LOQED Power Kit
With the LOQED Power Kit you no longer need to buy new batteries. It includes 8 rechargeable Ni-MH batteries and a 3-metre charging cable. When the lock reports the batteries are almost empty, simply connect the charger – the cable is usually long enough to charge without a nearby socket.
Remember: if you ever switch back from Ni-MH to alkaline batteries, change the battery type via LOQED app → Select your lock → My Lock → Batteries & Charging → Alkaline.
Still need help?
If you have completed these steps and still experience fast battery drain, contact the LOQED support team through Live Chat in the LOQED app (via the menu). Where possible, include a photo of your batteries and a short video of the lock locking and unlocking.
