Notes on Common Keychains
Most condo/apartment amenity keychains (pools, gyms, elevators) use low-frequency 125 kHz passive RFID (e.g., TK4100, T5577, EM4200/EM4305). If a key fob opens the individual apartment unit door, it’s typically a high-frequency 13.56 MHz system (e.g., MIFARE 1K or NTAG213).
