● Electronic key is out of reception range.
● The battery voltage is too low. ● Overload of the central locking system by operating at frequent
intervals; the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
To rectify the cause of the fault,
change the position of the electronic
key.
