To reactivate the entry function properly, perform any of the following: (a) Press the lock button on the outside door handle while carrying the electronic key. (b) Perform a wireless remote control function. (c) Insert and turn the mechanical key in the keyhole of the door.

If battery power becomes insufficient, replace the battery with a new one.
