AWID vs. DoorKing vs. HID: Which Format Does Your Gate Use?

If your gated community or parking gate has been issuing cards that simply don’t work, there is a good chance the wrong format was ordered. DoorKing gate readers use the AWID proximity protocol — not the HID standard that dominates office buildings — and mixing the two produces cards that read as blank. American Key Cards supplies AWID-format DKProx-compatible cards and fobs directly, without a dealer account, programmed to your facility code.

Why Three Different Formats Matter at the Gate

Most people assume that any 125 kHz proximity card works in any 125 kHz reader. That is not true. Three distinct air-interface protocols dominate gate access installations in North America:

1. AWID 26-bit — used by AWID SP-6820 and SR-2400 readers, and by DoorKing 1815-series readers (which are AWID readers under a DoorKing brand)
2. DoorKing DKProx — the DoorKing branded line of AWID-format credentials; same protocol, different label
3. HID Prox H10301 — the most widely deployed office-building format, used by HID MaxiProx 5375, ProxPro 5355, MiniProx 5365, and ProxPoint Plus 6005 readers

All three transmit standard 26-bit Wiegand data to the access panel. The difference lies entirely in the encoding layer between card and reader. HID cards and AWID cards both carry a facility code (1–255) and card number (1–65,535), but the RF modulation that carries those bits to the reader is different. An AWID reader cannot decode an HID card, and an HID reader cannot decode an AWID card.

This is the root cause of the most common gate card ordering mistake: a property manager with a DoorKing system orders standard HID-compatible cards because they are easy to find, and receives a batch of cards that trigger no response from any reader on the property.

How to Identify Your Gate Reader

Before ordering any replacement cards, confirm your reader type. Here is what to look for:

DoorKing readers are almost always integrated into a telephone-entry or intercom column — the full unit carries the DoorKing or DKS logo. The proximity reader module inside is a DoorKing 1815-series unit. Common sub-models include:

• 1815-300, 1815-301, 1815-302 — flush-mount DKProx readers
• 1815-330, 1815-331 — surface-mount DKProx readers
• 1815-281 (AWID SP-6820) and 1815-282 (AWID MM-6800) — DoorKing-rebranded AWID readers

If you see a standalone reader column (not an intercom) with the AWID logo, you have a direct AWID installation. Look for model numbers SP-6820, SR-2400, KP-6840, or MM-6800.

HID readers at gate installations are less common but do occur — especially at commercial parking facilities that installed office-standard access control infrastructure. HID readers show the HID logo and carry model codes starting with 5 (MaxiProx, ProxPro, MiniProx) or 6 (ProxPoint).

If labels have weathered away, pull the reader from the wall and check the back panel or the access controller enclosure for model documentation from the original installation.

DoorKing DKProx Is the AWID Format in Disguise

The DoorKing DKProx line is the most searched gate card format in the U.S. aftermarket — and the most frequently mis-sourced. DoorKing sells these credentials exclusively through its authorized dealer network, which locks out property managers who want to reorder cards independently.

The OEM part numbers for DKProx cards are:

• 1508-120 — standard clamshell card
• 1508-121 — ISO printable card (for photo ID or graphic printing)
• 1508-123 — key fob
• 1508-021 — adhesive disk credential
• 1508-198 — dual DKProx / UHF credential (for combined gate and UHF lane access)

All of these use the AWID 26-bit protocol at 125 kHz. Facility code range is 0–255; card number range is 0–65,535. American Key Cards produces compatible DKProx-format cards and fobs to the same specification, without requiring a DoorKing dealer account. Before you switch to aftermarket cards, homeowners often ask whether the fobs can be copied at all — our answer to whether DoorKing DKProx cards can be cloned covers what the DKProx format does and doesn’t protect against.

AWID SP-6820 and SR-2400 Standalone Readers

Some gate and parking installations — particularly multi-family apartment complexes and surface parking lots — use AWID readers directly rather than DoorKing integrated systems. The SP-6820 and SR-2400 are the most common AWID reader models in these deployments.

The card line for direct AWID installations uses part numbers like CS-AWID-0-0 (clamshell), GR-AWID-0-0 (printable ISO card), AW-PROXLINC-CS, and AW-PROXLINC-GR. These are functionally interchangeable with DKProx cards at the RF level — both use the same AWID 26-bit air interface. You can read more about standalone AWID installations on the AWID 26-bit format page, and our AWID 26-bit compatible cards buyer’s guide walks through the ordering details for those readers.

HID Prox H10301 at Gate Installations

HID H10301 26-bit cards (OEM part numbers 1386, 1326, 1346, 1586) are the right choice when your gate reader carries an HID logo. These are far more common at commercial parking garages and office building entry points than at residential gates. If you have confirmed HID hardware, standard 26-bit H10301-format cards will work — and these are the most widely available format in the aftermarket. More detail is available on the HID Prox H10301 format page.

How AWID / DKProx and HID H10301 Compare

Feature	AWID / DKProx (1508-120, CS-AWID-0-0)	HID Prox H10301 (1386, 1326)
Frequency	125 kHz	125 kHz
Bit format	26-bit Wiegand (AWID protocol)	26-bit Wiegand (H10301)
Facility code range	0–255	0–255
Card number range	0–65,535	0–65,535
Air interface	AWID proprietary	HID proprietary
Interchangeable?	No — format-specific readers required	No — format-specific readers required
Cloneable?	Yes (no encryption)	Yes (no encryption)
Typical gate brand	DoorKing, AWID	HID, Identiv, multi-tech
AKC compatible card	Yes — DKProx/AWID format	Yes — H10301 format

Both formats operate at 125 kHz and carry the same 26-bit data structure. Neither carries cryptographic protection. The distinction that matters is the air-interface encoding — AWID readers need AWID cards, HID readers need HID cards.

What Cloneability Means for Gate Security

Because neither AWID DKProx nor HID H10301 uses encryption, both formats can technically be duplicated with commercially available RFID copier tools. This is a known characteristic of 125 kHz proximity technology generally, not a flaw specific to any one brand.

For most residential gate and parking installations, the practical security concern is unauthorized card duplication by tenants or former employees, not sophisticated attacks. The access panel’s facility code and card number enrollment database is the primary security control — deactivating a card number immediately removes access regardless of how many physical copies exist.

If your installation requires clone-resistant credentials, you would need to move to a 13.56 MHz smart card platform (such as MIFARE DESFire or HID iCLASS SE), which requires replacing both readers and cards. American Key Cards does not supply DESFire or iCLASS SE credentials, as those secured formats cannot be reproduced outside the OEM issuance chain.

What You Need to Order Compatible Gate Cards

Whether your gate uses DoorKing DKProx, standalone AWID, or HID format, the ordering information is the same:

1. Facility code — a number from 0 to 255 that identifies your site. This is programmed into the access controller and must match every card you issue. Find it on an existing card label, in the controller’s programming menu, or in your installer’s records.
2. Card number range — the individual card numbers you want to assign, from 1 to 65,535.
3. Quantity and form factor — clamshell card, ISO printable card, or key fob.
4. Format confirmation — AWID/DKProx or HID H10301.

American Key Cards programs each batch to your exact facility code and card number range before shipment. Cards arrive ready for enrollment in your DoorKing 1835/1830, AWID-based panel, or HID-compatible controller — no programming hardware needed on your end.

Why Compatible Cards Cost Less Than OEM

The gate market is where the dealer-channel markup shows most plainly, because all three brands route the same way. DoorKing sells 1508-120 and 1508-121 cards only through its authorized network; AWID moves through integrators; HID’s 1386 and 1326 cards, while cheaper because they are commodity, still carry distributor margin at the OEM tier. Whichever format your gate uses, part of the price you pay is the channel, not the chip.

American Key Cards programs the AWID, DKProx, or H10301 encoding directly and ships without a dealer account. A community that once waited on a DoorKing dealer for a twelve-card reorder gets the same facility-code-matched card at the price the technology actually costs. The card reads identically at the gate — the only line that leaves is the markup.

Confirm Your Format Before You Order

Confirm your reader brand and model before you order anything — it is the one step that separates a working batch from wasted money. HID cards ordered for a DoorKing system read as blank. DKProx cards ordered for an HID-reader installation are equally useless. Five minutes checking the reader housing or your installer paperwork saves the reorder. If you manage the gates for a homeowners association, our HOA gate access card guide covers the reorder workflow for community entrances end to end.

If you are not sure what format your gate uses, contact us with photos of your reader or the model numbers from your access controller. We will confirm the correct format and provide a quote for compatible cards or fobs in the quantity you need.
