A keyless entry system for a vehicle is provided, on the vehicle, with detection distance setting means for changing a detection distance within which an electronic key can receive an activation signal. The fastener assembly comprises an elongated member extending between proximal and distal ends. The center unit includes a key controller configured to renew the common cipher-key so as to be identical with the renewed common cipher-key in case of receiving the demand from the transmitter and an encoder configured to produce the encrypted data by encrypting a cipher-key with the renewed common cipher-key and to transmit the encrypted data to the terminal unit. The laser catheter may be activated to create a lumen through the occlusion. In addition, the MCU resource controller may create or generate a resource address that a participant in the conference may use to access the assigned MCU. A weight member is detachable from and attachable to the insertion recess of the pedal link member such that a vibration of the accelerator pedal can be minimized.
