Abstract
A vehicular door lock control apparatus for unlocking a door lock mechanism includes a key for performing a first unlocking operation and a second unlocking operation. A door key cylinder is actuable to an unlock position by using the key. The key is insertable into the door key cylinder. A transmitter-receiver is disposed at the key, and transmits an answer signal that indicates a specific identification code upon receipt of at least one of a power signal and an inquiry signal. An operating force transmission mechanism, actuable between a transmission mode and a non-transmission mode, transmits an unlocking force applied by the key during the second unlocking operation to the door lock mechanism when in the transmission mode. A control mechanism transmits at least one of the power signal and the inquiry signal to the transmitter-receiver when the key performs the first unlocking operation, and actuates the operating force transmission mechanism to the transmission mode when the identification code received from the transmitter-receiver conforms to a pre-set identification code.
