A motor vehicle comprising:
side doors;
power-operated locks associated with one or more of the side doors;
at least one of a hood or a trunk lid separate from the side doors; and
an electronic control system to centrally lock and unlock one or more of the power-operated locks in response to a command imparted by means of a mechanical key or an electronic key;
wherein power-operated key-cylinder-less locks are associated with all the side doors of the motor vehicle;
further comprising a key-cylinder hood or trunk lid lock associated with at least one of the hood or trunk lid;
wherein the electronic control system is further configured to sense operation of the key-cylinder lock associated with at least one of the hood or trunk lid by means of a mechanical key, and, upon determining a specific operation of the key-cylinder lock by means of the mechanical key, responsively unlock one or more of the power-operated key-cylinder-less locks associated with the side doors;
wherein the at least one of the hood or the trunk lid is arranged to close a compartment in which an electric energy source of the motor vehicle is housed; and
wherein the key-cylinder lock is a non-power-operated lock.
