1. Device for the telecontrol of an object (V), of the type comprising an interrogator unit (OI) capable of effecting a primary interrogation using waves (EIB1, EIA1) so as selectively to interrogate at least one primary receiver/transmitter cell (1) housed in or on said object (V) and containing in primary storage means (M1) a first code (C1), and of receiving using waves from said primary cell (1) a primary response (ERB1, ERA1) able to represent a part at least of this first code,characterized in that it furthermore comprises at least one secondary receiver/transmitter cell (2) housed in or on said object (V) and containing in secondary storage means (M2) a second code (C2) and a first representation (FR1) of a part at least of the first code (C1), and capable of transmitting, in response to a secondary interrogation (EIB2), a secondary response (ERB2) able to represent a part at least of this second code (C2), as well as of transmitting, after a primary interrogation of the primary cell (EIB1, EIA1) and a secondary interrogation of the secondary cell (EIB2), at least one complementary response (ERC) in response to a complementary interrogation (EIC) effected by the interrogator unit (OI), said complementary interrogation (EIC) containing a second representation (SR2) of a part at least of the first and second codes transmitted respectively by said primary (1) and secondary (2) cells in response to the primary and secondary interrogations (EIB1, EIA1 and EIB2),this allowing the secondary cell (2) to effect a complementary response (ERC) depending on the primary and secondary responses of the primary (1) and secondary (2) cells, respectively.
