That’s a HID ProxKey II fob. It’s indeed an LF chip. AFAIK, it should be cloneable to one of the T5577 stickers Eriequiet linked.
Amal mentions it here, albeit a bit unsure:
For that purpose, the blue cloner is a decent and cheap option. However, Dangerous Things doesn’t sell them anymore, and the ones you can get on Amazon or AliExpress aren’t always guaranteed to support HID. The Proxmark 3 Easy is the better option, but it’s much more complicated to set up, and not ideal for cloning a single fob. If you have any lasting interest in RFID, it’s a good investment though.
