You can order 34-bit cards/fobs from about any HID distributor, but Honeywell probably buys 10,000 or more at a time and gets commensurate pricing, so if you're looking for a deal, you may not find it. At a minimum you'll need the Facility ID and the Starting ID Number to place an order. You might want to send a working card or fob to a card vendor and let them get the information from it. They are all over the Web.
For a price, big corporate accounts and manufacturers can "buy" a Facility ID that a card manufacturer won't sell to anyone else. If this is what Honeywell has done, your only source may be Honeywell.
Good luck!!
