• How do I unlock a MIWA hotel lock with a smartphone?

  For locks equipped with BLE (such as ALV2/ALV3 series), launch the dedicated hotel app, tap the unlock button, and hold your smartphone near the lock reader until the LED flashes green.

• What does a red light indicate on the lock?

  A red light typically indicates that the card or key used is invalid or verification failed. If the red light flashes in a specific pattern, it may indicate a low battery or other system error.

• How often do MIWA lock batteries need replacing?

  The main batteries (typically four AA alkalines) generally last about 1.5 years with average usage (approx. 10 operations per day). The system will alert property staff when voltageは低いです。

• Can I use a mechanical key if the batteries die?

  Most MIWA electronic locks are designed with emergency override capabilities. Hotel staff can use an emergency card or a mechanical key override/cylinder if installed, or an external power supply unit depending on the model.
