Here is a link to a simple mod.  It has the same link to the FOB that Dave mentioned. These definitely are NOT potted. There is quantity pricing that brings the price down to about $2.40 shipped in quantities of 10. Perhaps someone could mail you a couple if you cannot buy where you are?

Subject: Re: [App_rpt-users] CM108 fobs with potted chips.

Thanks. That looks exactly like the ones I have. The seller won't ship to me, I am not in the US. Is there a way to tell without buying them? TIA.

Hi Geoff,

No, those connections won't get you what's needed, unfortunately.
Non-potted CM108's are inexpensively available, however. Here is the one
example that I'm using: http://www.ebay.com/itm/291156304476
