1. A system for unlocking a key cylinderless vehicle closure, the system comprising:
- an electric lock with an electrical release and a mechanical release, wherein the mechanical release can be enabled and disabled;
a selective coupling mechanism that enables the mechanical release of the electric lock if the electric lock fails;
a portable object having an object identification;
an interrogating circuit that powers and interrogates the portable object, wherein the interrogating circuit includes a control logic that controls operation of the electric lock, the control logic sends a control signal to the electric lock authorizing the electric lock to be unlocked based on the object identification, and the control signal is sent to the selective coupling mechanism in conditions of power supply failure to enable the mechanical release of the electric lock based on the object identification; and
a power supply that supplies power to the interrogating circuit.

Abstract
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.
