We had to get our strata manager to write an authorisation letter that we could give to the locksmith before we could get keys for the EC. Note that (in Sydney, at least) there are 2 types of keys – NMB and Abloy. NMB is the older type of key. Locksmith is able to provide these easily. I understand locksmiths can’t cut Abloy keys, and it’s a much bigger hassle to get these.
