A system for unlocking a key cylinderless automobile vehicle door includes a portable object having an identifier and a circuit for interrogating the object. The circuit powers the object and interrogates the object when it is outside the vehicle. The interrogating circuit supplies a signal authorizing unlocking of the door as a function of the identifier. A standby power supply, which is separate from the main power supply of the vehicle, also powers the circuit and the object. As a result, the vehicle door does not require a key cylinder while still ensuring unlocking even if the main power supply of the vehicle fails.

An automobile vehicle lock is released under normal operating conditions by an electric motor. Under degraded conditions, a mechanical release of the lock is enabled. This allows the motor providing electrical release of the lock to be simply dimensioned for release under normal operating conditions with no requirement to over-dimension the motor to ensure the lock will open under degraded operating conditions. Because release of the lock is mechanical under degraded operating conditions, enablement of the mechanical release is provided by a low-power standby motor. This allows a compact and inexpensive standby power source to be employed.
