- the wireless door lock remote control operational area differs depending on the situation.
- The operational area differs depending on the operators and the ways the transmitter is held.
- In certain areas, the remote control function will only operate partially for the operational area will be reduced due to the vehicle body shape and the influence of the surrounding environment.
- Since the transmitter uses faint electric waves, strong electric waves or noise in the frequency used may reduce the operational area or the remote control may not function.
- When the battery weakens, the operational area is reduced or the remote control may not function.
Hint
: if the door control transmitter has been left in a place that is exposed to direct sunlight, such as on the instrument panel, it may cause the battery to weaken or cause other such problems.
