DoorKing DKProx (1508 Series, 26-bit / AWID protocol) Compatible Cards & Fobs
The gate-world staple: DoorKing's DKProx credentials ride the AWID air interface with 26-bit Wiegand output, feeding 1830/1835 controllers at apartment complexes, gated communities, and parking structures across the country.

DoorKing owns the American gate: the 1830-series telephone-entry and access controllers run thousands of multi-family communities, and the DKProx credential line — 1508-series cards and fobs read by 1815-series readers — is how residents get through. Under the hood, DKProx speaks the AWID air-interface protocol, which is why an HID-family card at the same 125 kHz frequency does nothing at a DoorKing gate: right frequency, wrong radio language. Property managers reorder these constantly as residents move in and lose fobs, and the OEM path typically runs through installing dealers. We supply unbranded DKProx-compatible clamshells and fobs programmed to your facility code and card-number range, verified on the AWID protocol before shipping — they enroll in your 1830/1835 account management exactly like the stock you already issue.

Why won't standard HID-family cards work on my DoorKing reader?
DKProx readers listen for the AWID air-interface protocol. Cards built for other 125 kHz families transmit differently at the same frequency, so the reader never decodes them. Replacements must be AWID-protocol credentials programmed with your system's 26-bit data.
Can I order DKProx-compatible cards without going through a DoorKing dealer?
Yes — that's what compatible-by-specification supply is for. Give us your facility code and number range (both visible in your 1830-series account software or printed on existing stock) and we program and verify each batch directly. For OEM-branded stock, your DoorKing dealer remains the channel.
Are 1508-120 and 1508-121 the same format?
They're the same DKProx credential family in different packaging/numbering options; both carry AWID-protocol 26-bit data. Tell us which style your fleet uses and we match the form factor — the programming logic is identical.
Do compatible fobs work at long-range vehicle readers?
Yes, within the physics of passive credentials: read range at any 125 kHz reader depends mostly on the reader's antenna and the credential's coil size. Fobs read shorter than cards everywhere, ours and originals alike; for maximum vehicle-lane range, cards or windshield credentials outperform keyring fobs.
