The present invention relates to a process for opening a container for the transportation of valuable objects or valuable documents, for example. The container (1) includes a first electronic unit (2), which allows deactivation of an alarm system and/or opening of the container. A first key (10) required to open the container includes a second electronic unit (12), which communicates with the first electronic unit (2) such as to initiate opening of the container. There is used a stationarily disposed second key (20) which together with the first key (10) provides the complete code-set (ABCD) required to initiate deactivation and/or opening of the container (1). The stationarily disposed second key (20) includes a third electronic unit (22) which contains a subset (CD) of the complete code-set (ABCD) required to initiate deactivation and/or opening of the container (1). The electronic unit (12) of the first key (10) contains a subset (AB) of the complete code (ABCD) required to initiate deactivation and/or opening of the container (1). The inventive process ensures that the container (1) will be opened at the correct geographic destination and, when necessary, also within a determined time span.
