I'm still thinking about this, what Nicole says makes sense although deposit probably does denote "money". I still like temporary storage agreement as effectively the idea is storage in the absence of the customer. It doesn't specify for how long the storage will be. They do mention that sometimes a key will be needed, but not in all cases. Temporary storage is general enough not to get into trouble (i.e. without specifying in the translation something which may not be true). I'm going to leave the question open in case anybody else comes up wi¡th something.
Thanks to both Eva & Nicole for your help,
Tara
