The present invention provides a method for releasing and for controlled storage of a desired predetermined value into a preset value memory storage of a postage metering machine. Initial values are transmitted in each case from a postage metering machine to a release apparatus. A first key code word is determined by a first algorithm module section from initial values and from values stored in a first memory storage associated with the postage metering machine. A second key code word is determined by a second algorithm module section from initial values and from values stored in a visually readable table associated with a second memory storage in the release apparatus. The second key word is transmitted from the release apparatus to the postage metering machine, where it is stored in a storage memory section and compared with the first key word in a locked section of memory. A random number is generated in a random number generator in the postage metering machine and is transmitted to the release apparatus, where it is stored in the memory storage of the second algorithm module section as a seed value for a future transmitting of a second key word. The random number is stored in the memory storage of the first algorithm module section as a comparison value for a future unlocking.
