摘要： A method is provided for configuring an operation mode of a passive entry system of a vehicle. A configuration mode of a vehicle based communication module is enabled by depressing a predetermined combination of actuation buttons on a portable communication device to broadcast a configuration mode command signal. A passive entry configuration is selected by depressing a respective actuation button on the portable communication device when in the configuration mode. The portable communication device broadcasts a corresponding command signal to the vehicle based communication module identifying the selection. The corresponding command signal is received from the portable communication device and the selected passive entry configuration is adopted in response thereto.

摘要： Memory contents in an electronic key are re-programmed using a base station from a multi-byte pre-existing or default value. If writing the new secret code value is interrupted and results in a partially-written value then a first recovery code is formed comprising a leading portion having values matching a corresponding portion of the pre-existing secret code and a trailing portion having values matching a corresponding portion of the new secret code. The first recovery code is transmitted to the electronic key for comparison with the stored secret code value. The electronic key compares a received secret code value in response to the first recovery code with the stored secret code value. If the comparison detects a non-match, then interaction with the base station is suspended. If the comparison detects a match, then interaction with the base station is continued in order to accept the new secret code value after re-transmission in full from the base station.

摘要： A passive entry system for a vehicle is provided that includes a vehicle-based communication module mounted in the vehicle and a portable communication device. The vehicle-based communication module includes a transmitter for transmitting a challenge signal to the portable communication device when in a polling state to determine a presence of the portable communication device for allowing access to the vehicle. The portable communication device includes a receiver for receiving the challenge signal and is responsive to the challenge signal when in a response state and non-responsive to the challenge signal when in a non-response state.

摘要： A method and system for relearning a previously programmed, authenticated key. The system includes an electronic control module (ECM) and a key. The method begins when the ECM fails to match an identification code (ID) of the key with all active or disabled IDs that are stored within the ECM. Thereafter, the ECM sends a signal to the key by encryption with a default secret code. If the key does not respond to this signal, then the ECM sends a signal to the key by encryption with one of a series of unique secret codes. The key receives this signal and then transmits an encrypted valid response signal to the ECM. The ECM extracts a key password from the encrypted valid response signal and compares this key password to a module password. Thereafter, the ECM determines that the passwords are identical and the ECM stores the key ID.

摘要： A system for determining a total number of access devices associated with a target includes a controller and an access device. The controller may be configured to control operation of the target. The access device includes a partially restricted memory configured to store the total number of the access devices associated with the target and to provide unrestricted read access to the total number, and a restricted memory configured to store a password. A read operation of the restricted memory is restricted by an authorization code.
