Secura Key carved out a durable niche with standalone readers that don't need a panel at all: an RK600 on the wall holds its own card list, which made it the go-to for small offices, gates, pool doors, and clubhouses. The Radio Key credential line serves those units and the larger RK65K family, most commonly in the 26-bit Format 201 layout, with Format 303's 32-bit structure available where more facility codes were needed. Because so many of these systems run for decades under light management, replacement time often arrives with no records at all — which is fine: the printed numbering on a working card usually contains everything needed. We program unbranded, compatible-by-specification Radio Key-style cards and key tags to your facility code and number range and verify the layout before shipment, so new stock enrolls on your readers exactly like the originals.

What is the Radio Key format?
Secura Key's 125 kHz credential encoding for the RK-series readers — Format 201 carries standard 26-bit facility-code-plus-card-number data, and Format 303 extends the facility-code space in a 32-bit layout. Your reader accepts whichever it was configured for.
Will your compatible cards work on my RK600?
Yes — programmed in your system's format with your facility code, they enroll on RK600/RK600e and RK65K units through the normal card-add procedure. The reader accepts the data, not the brand.
Can Radio Key credentials be used on non-Secura Key readers?
When your system uses the RKDT dual-technology readers or standard 26-bit Wiegand output, correctly formatted credentials interoperate with generic Wiegand infrastructure. Native RK-series standalone units read Secura Key-protocol credentials specifically, so match the credential to the reader family.
I have no paperwork for a 20-year-old system — can you still match it?
Usually, yes. Send clear photos of both sides of a working card and your reader model; the printed numbering plus format conventions typically identify facility code, card number, and layout. We confirm everything before production so the batch works on arrival.
