FAQ – Troubleshooting
The battery depletes within a few days
– Please confirm whether the firmware is up to date.
– In locations with very poor reception, transmission and location positioning times will increase, thus as a result battery run time may become much shorter than expected.
– For Gen2 devices, check if the regular transmission interval is in short intervals. It is recommended to set it to at least 180 minutes unless absolutely necessary.
– If the operation time has decreased suddenly, there might be a chance of battery failure.
The LED is constantly on (blue, red, purple)
– The LED lights up during USB charging. It flashes blue during alarm activation, positioning, and communication.
– If the LED is constantly on (blue, red, purple) when not charging, the device may be faulty.
The LED does not light up red or blue while charging
– Try using a different USB cable or flip the direction of the connector.
– If you are using a portable charger, charging may stop near full charge and the LED will turn off. This is a common behavior of when charging with portable charger..
The LED does not flash when pressing the button during device registration
– Charge the device first and then unplug the USB cable. Then, pressing down the button firmly for more than 3 seconds will make the LED flash.
– Next, press and hold the AlterLock device button for more than 10-15 seconds to restart the device. The reboot will complete in a few seconds.
– If the issue persists after restarting, the device may be faulty.
No alarm sound
– The alarm activates after the device is set to Lock mode and a certain level of movement is detected. However, the alarm might not sound due to the following settings or conditions:
– The alarm setting is turned off.
– The “Alarm Limit” set while in the Lock mode has been exceeded.
– The mobile phone’s battery is low, and the alarm has been automatically turned off.
– Right after setting to Lock mode. *After setting to Lock mode, a stationary state of about 1-2 seconds is required for the alarm to sound properly.
If none of the above apply or the volume has become extremely low, the device might be faulty.
If you suspect a fault based on the above symptoms, please check the warranty period and apply for an exchange via the contact form by selecting “Return/Exchange” > “Exchange”.

Please check the following if location information cannot be obtained:
– As this service is specialized in theft prevention, it does not acquire real-time location information. The AlterLock device will start acquiring location information and notify the smartphone after detecting an anomaly. That is because unless someone moves your vehicle, it will stay where it was stored, therefore no need to check its location.
– For the first motion detection after setting to Lock mode, to prioritize prompt reporting, no location information is acquired and only a notification is sent. Location information acquisition begins after the second motion detection while in Lock mode.
– Unlocking or pressing the “Misdetection” button in the app before the completion of location acquisition may cancel the process.
– To facilitate the identification of the last known location in the event of unfortunate theft, location information acquisition starts after the device becomes stationary. Please wait up to 3 minutes in a stationary state after the second and subsequent motion detections.
– To minimize battery consumption and enable long-term tracking, the device enters a standby mode when it does not detect movement for 1 minute after data transmission.
How to Confirm Location Information Acquisition
1. Turn off the alarm.
2. After setting the device to Lock mtate, wait more than 3 seconds and then shake the device.
3. Confirm that a notification is received. *Do not unlock or tap “Misdetection” during this time.
4. Wait few seconds then shake the device again and wait until the LED’s blinking stops completely, then confirm that a notification is received.

This feature is functional when the mobile phone and the device are connected via Bluetooth and the device is receiving a Bluetooth signal of sufficient strength.
The signal strength is determined based on the signal strength from the mobile phone at the time of device registration.
The signal from the cell phone may be weak due to the cell phone case, proximity to the body, etc. Please adjust “Button Operation Range” from “Advanced Settings” > “Device” in the app to the low side if button is not working even when close by.
This feature operates when the mobile phone and the device are connected via Bluetooth, and the device is receiving a Bluetooth signal of sufficient strength.
The Bluetooth signal strength is determined based on the signal strength from the mobile phone at the time of device registration.
The signal from the mobile phone may be weak due to few factors such as the signal conditions at the time of device registration, the mobile phone case, or being held at close proximity to the body. Move about 1-3 meters away from the device and adjust the “Button Operation Range” from “Advanced Settings” > “Device” in the app.
Adjusting while away from the device can make the button responsive even in weak signal conditions.
The auto-lock function automatically switches the lock state based on the Bluetooth connection status with the smartphone and signal strength.
When the device is in close in proximity with the smartphone it enters the lock mode.
Please adjust the auto-lock sensitivity to the low side in “Advanced Settings” > “Devices”. If it is already at the minimum value, it is possible that the Bluetooth signal of the smartphone may be weak by default. When the smartphone is made of metal frame/casing or is in close contact with the human body, the signal strength may significantly decrease, causing it to enter the lock state even at close distances.
Even when approaching the device, it does not enter the unlock mode or takes time.
In this case, Bluetooth may be disconnected or the signal may be weaken due to the smartphone’s power-saving features or certain apps. Please try disabling the power-saving feature. Also, when using the AlterLock device, keep the app running in the background.
Depending on the smartphone model and settings, Bluetooth connection might take time or fail to reconnect after the smartphone has been in sleep mode for a long time. In such cases, please exit sleep mode and display the app.
Even if the distance between the device and smartphone has not changed, the lock state switches intermittently.
Especially indoors, where there are many devices emitting electromagnetic waves near the device and smartphone, intermittent signal interference may occur, causing the lock state to switch unexpectedly.
If Bluetooth is unstable
The Bluetooth connection might be unstable depending on the smartphone model, OS version, or individual differences. Updating the OS, restarting the device, resetting the network, or disconnecting other Bluetooth devices may improve the situation. For details on OS updates, please contact the manufacturer of your mobile phone.
The device does not reconnect after a firmware update
Press and hold the AlterLock device button for more than 10 seconds to restart the device.
The restart will complete in a few seconds then try reconnecting AlterLock via the app.
Firmware update failed midway
The device will automatically reboot with the original firmware. This process may take several minutes.
If push notifications are not received even when movement is detected in the locked state, the following possibilities can be considered:
– Notifications may be turned off in the app settings.
– Notifications for AlterLock app may not be permitted in the OS settings.
– If outside the Bluetooth communication range, it may be in an area where remote communication is not possible or underground or in an area with poor radio wave conditions.
– The smartphone may not be connected to the internet.
– There may be disruptions or delays due to Google or Apple’s notification platforms.
