Abstract
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.
