Taiwan Daedalus has been manufacturing electronic deadbolt locks for international and Taiwanese customers. These electronic door locks combine the features of traditional keyed locks and electronic keypad door locks. They are simple to program and use due to the easy-to-press touchpad buttons and the easily programmed code combination. However, once the code is entered, it still needs to be turned and unlocked manually.
These electronic deadbolt locks feature a warning sound. The alarm will go off after four incorrect code entries, and the keypad will be disabled for 30 seconds. These products also feature low battery indication. An auto-alarm function will beep to remind the user that the battery needs to be replaced.
