I dug out my Keysy after it has been sitting in a drawer for over a year, determined the antenna had broken free from the solder pads, and resoldered it. I have since successfully cloned both my office and apartment access cards. Looking at some of the Kickstarter updates around the Keysy, they refer to T5577 fobs here. I’m quite certain I can now use the NeXT for accessing either site, plus whatever use I find for the HF portion. I’ve also ordered the 3-beep, blue cloner recommended by user @turbo2ltr but won’t have it until next week. I’m pretty sure I’m going to proceed with one NeXT to start, but I’m not sure I want to shell out the dough for a Proxmark III. Surely there has to be people in this community who own them and are willing to do some reading/writing for the price of a bottle of wine?
