PAC Stanley Compatible Key Fob

125 kHz LF

A compatible replacement for PAC International PAC / Stanley (PAC 8x32) — a 125 kHz proximity credential, encoded by specification to read identically on your existing readers. Order single spares or bulk quantities at a fraction of OEM list pricing.

How the compatible PAC / Stanley (PAC 8x32) works

The PAC / Stanley (PAC 8x32) is a 125 kHz low-frequency proximity credential — the band most legacy prox readers use. Its data structure is NRZ; PAC/Stanley 8-digit hex ID format (facility + ID); proprietary LF token encoding. 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.

We build the compatible PAC / Stanley (PAC 8x32) by encoding the matching data structure onto a programmable T5577 / EM4305 chip. Once written, the credential presents the same bits, the same facility code, and the same card number your reader already accepts. That is what "compatible by specification" means: not a generic look-alike, but a credential engineered for the exact format your system expects.

To order, tell us the part number or format printed on your existing PAC International card, 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.

PAC / Stanley (PAC 8x32) — common questions

Is this a genuine PAC International card or a compatible one?

It is an independently manufactured compatible credential — engineered to the same specification as the PAC / Stanley (PAC 8x32) so it reads identically on your existing readers, but it is not an PAC International-branded product. Security ID Systems is independent and not affiliated with PAC International; your access-control panel accepts the credential exactly the same way.

What chip is the compatible PAC / Stanley (PAC 8x32) encoded on?

It is encoded on a T5577 / EM4305 programmable chip. That platform carries the original 125 kHz LF data structure precisely, so the credential presents the same information your readers already accept.

What frequency and format is the PAC / Stanley (PAC 8x32)?

It operates on 125 kHz LF, using nrz; pac/stanley 8-digit hex id format (facility + id); proprietary lf token encoding. 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 PAC International format hard to find?

The PAC International 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.
