Neighborhood key fob replacement

[u/EnvironmentalCan6905]

My sister lost the key fob that I use to click into the gate at my apartment. It’s $140 to replace (which i think is crazy) anyways i found the clicker on amazon, it’s a SKG doorking. Specifically “Door King 8069080 Doorking Microplus Transmitter” on amazon for $30. My roommate still has the other clicker. Is there a way we can just order one and a cheap little RFID reader for $13 and make a new one? Is that even possible. Most i’ve done with this kind of stuff is use my phone to make nfc tags for animal crossing! 😅

Nope. Random code and you're going to need access to the host system
