Secura Key's Radio Key product line uses a proprietary 125 kHz IC with Dynascan® auto-tuning for extended read range, encoded in either 26-bit (Format 201) or 32-bit (Format 303) Wiegand output formats; the RKDT dual-technology readers also accept standard HID 26-bit credentials. American Key Cards supplies Radio Key-compatible clamshell cards and key tags pre-encoded to your facility code, filling a significant supply gap as Secura Key distributes primarily through its restricted dealer network.

Can Securakey Radio Key (26-bit / 32-bit Wiegand) cards be copied?

Securakey Radio Key (26-bit / 32-bit Wiegand) is an open format, so a compatible card can be produced from your facility code and card number. We don't copy individual cards on request — we manufacture new, correctly-encoded credentials for systems you own or manage.

Securakey Radio Key credentials operate at 125 kHz with no cryptographic protection. The proprietary format does not prevent reading by standard RFID tools; T5577 blanks programmed via Proxmark3 can emulate Securakey-format cards. For higher security, Secura Key also offers MIFARE-based multi-technology credentials.
