ProDataKey Compatible Fob

125 kHz LF

A compatible blank credential built on the matching AES-secured 13.56 MHz smart card / T5577 platform — supplied ready for your own system to enrol as a drop-in spare for ProDataKey (PDK) Standard Fob / Red (125 kHz layer). Order single spares or bulk quantities at a fraction of OEM list pricing.

How the compatible ProDataKey (PDK) Standard Fob / Red (125 kHz layer) works

The ProDataKey (PDK) Standard Fob / Red (125 kHz layer) is a 125 kHz low-frequency proximity credential — the band most legacy prox readers use. Its data structure is PDK Standard = 125 kHz HID-compatible 26-bit (H10301); PDK Red = an AES-secured 13.56 MHz 8K smart card secure + 125 kHz HID 26-37 bit prox on one card. When you present a credential, the reader decodes that exact structure and passes it to your access-control panel as a card number it recognises.

Because the ProDataKey (PDK) Standard Fob / Red (125 kHz layer) is a secured smart credential, it is designed so the encryption keys stay under your control. We supply compatible blank credentials built on the matching AES-secured 13.56 MHz smart card / T5577 platform, ready for your access-control system or integrator to enrol exactly as it would credentials ordered through the original vendor's channel. You get drop-in spares and bulk stock at a fraction of OEM pricing — and because your own system writes the keys, every credential inherits your site's security.

To order, tell us the part number or format printed on your existing ProDataKey card, along with your facility code and card-number range, and our specialists confirm the encoding before anything ships. Bulk and reorder quantities are welcome — pricing is a fraction of OEM list, and every credential is verified to read on your existing equipment.

ProDataKey (PDK) Standard Fob / Red (125 kHz layer) — common questions

Is this a genuine ProDataKey card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the ProDataKey (PDK) Standard Fob / Red (125 kHz layer) so it reads identically on your existing readers, but it is not an ProDataKey-branded product. Security ID Systems is independent and not affiliated with ProDataKey; your access-control panel accepts the credential exactly the same way.

How do you supply a replacement for my secured ProDataKey smart card?

The ProDataKey (PDK) Standard Fob / Red (125 kHz layer) is a secured smart credential, so the encryption keys stay under your control. We supply compatible blank credentials on the matching AES-secured 13.56 MHz smart card / T5577 platform that your own system or integrator enrols — exactly like ordering blanks through the original vendor's channel, at a fraction of the cost. Because your system writes the keys, the credential inherits your site's security.

What frequency and format is the ProDataKey (PDK) Standard Fob / Red (125 kHz layer)?

It operates on 125 kHz LF, using pdk standard = 125 khz hid-compatible 26-bit (h10301); pdk red = an aes-secured 13.56 mhz 8k smart card secure + 125 khz hid 26-37 bit prox on one card. Matching that exact frequency and data structure is what makes a compatible credential work — a card on the wrong band or bit length simply will not read.

Why is the ProDataKey format hard to find?

The ProDataKey format is one of the specialist, proprietary credentials that many card vendors don't offer. Security ID Systems focuses on exactly these specialist and legacy formats, encoding a compatible credential to the exact specification your readers already accept.
