How the compatible Schlage / Allegion ENGAGE (125 kHz prox tier) works
The Schlage / Allegion ENGAGE (125 kHz prox tier) is a dual-frequency credential operating on both 125 kHz LF and 13.56 MHz HF, so the compatible part must carry the correct data on whichever band your readers use. Its data structure is 125 kHz proximity (e.g; 26-bit H10301) alongside 13.56 Schlage Smart (DESFire) + BLE mobile. 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 Schlage / Allegion ENGAGE (125 kHz prox tier) 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 T5577 / EM4305 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 Allegion 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.
