HOA Gate Access Card Replacement Guide (DoorKing, AWID, Linear)
If your HOA or gated community uses a card or fob entry system, replacing lost credentials should not require calling the original gate company, waiting for a dealer quote, or paying elevated OEM pricing. For the two most common residential gate formats—DoorKing DKProx and Linear 26-bit Wiegand—American Key Cards supplies compatible cards and key fobs programmed to your facility code, shipped directly, with no dealer account required.
Why Gate Card Replacement Is Harder Than It Should Be
Residential gate systems are installed by access control contractors who typically specify one card format and source credentials through their own distribution channel. Once the installation is complete, the HOA board or property manager is left with a single reorder path: call the contractor, pay the markup, wait for delivery.
The underlying card technology in most residential gate systems is open, unencrypted 125 kHz proximity—the same technology available from multiple aftermarket suppliers. The perceived lock-in is a distribution arrangement, not a technical one. Understanding your format is the key to breaking out of the dealer cycle.
The Two Most Common HOA Gate Access Formats
DoorKing DKProx (AWID 26-Bit)
DoorKing is the dominant residential gate brand in the United States. Their DKProx credential line—part numbers 1508-120 (clamshell card), 1508-121 (ISO printable card), 1508-123, and 1508-021—are used with the DoorKing 1815-series proximity readers installed at gates, pedestrian entries, and parking barriers across apartment complexes and HOA communities.
The critical technical point: DoorKing DKProx readers use the AWID air-interface protocol, not the HID Prox protocol. Both carry 26-bit Wiegand data to the access panel, but the RF encoding between the card and the reader is fundamentally different. A standard HID ProxCard will not be read by a DKProx reader, and vice versa. This is the single most common ordering mistake in residential gate systems.
Compatible DoorKing 1815-series readers include the 1815-300, 1815-301, 1815-302, 1815-330, and 1815-331 surface-mount models. The reader housing almost always has the DoorKing name and the DKProx designation visible.
American Key Cards supplies compatible DKProx clamshell cards and key fobs in AWID 26-bit format, programmed to your facility code (0–255) and card number range (0–65,535). See the full DoorKing DKProx format guide for complete reader compatibility and part number details.
Linear and IEI 26-Bit Wiegand (HID-Compatible)
Linear and IEI (both Nortek Security & Control brands) produce widely used gate and door controllers for residential and light commercial applications, including the Linear eMerge series. Their proximity credentials use the standard HID H10301 26-bit Wiegand protocol—the same air interface as an HID 1326 ProxCard II.
This is a meaningfully different situation from DoorKing: because Linear readers use HID-compatible encoding, any properly programmed 26-bit H10301 card will work. Linear’s own OEM card part numbers include 0-297401, 0-299106, 0-297301A, and 830-00420. In many cases Linear’s OEM products are HID-manufactured cards with Linear branding (1386LGGMN is HID’s OEM part number for Linear).
American Key Cards supplies HID-compatible 26-bit clamshell cards and key fobs for Linear and IEI gate installations, programmed to your facility code. See the IEI and Linear 26-bit format page for full details.
Other HOA Gate Formats
Some residential communities have standalone AWID reader installations (most commonly the SP-6820 or SR-2400 models) that are not DoorKing-branded but use the same AWID 26-bit protocol. The ordering process is identical to DoorKing DKProx—provide facility code and card number range, and AKC ships AWID-format compatible credentials.
See the AWID 26-bit format guide if your community has AWID-branded readers rather than DoorKing hardware.

Cloneability and Security: An Honest Assessment
Standard DoorKing DKProx and Linear 26-bit credentials are unencrypted 125 kHz proximity cards. This means they can be duplicated with commercially available tools—that is a factual characteristic of the underlying technology, not a flaw unique to aftermarket cards.
For the vast majority of HOA and gated community applications, this is an acceptable risk. The primary security need is restricting vehicle and pedestrian access to residents, not defending against sophisticated credential attacks. Communities that have experienced significant card fraud or require stronger access assurance should consult their gate installer about upgrading to an encrypted smart credential system.
What this means for AKC’s compatible cards: our DKProx-compatible and Linear-compatible credentials are not clones of existing cards. They are newly manufactured credentials, programmed to your facility code and issued card numbers—the same programming process used when the gate system was originally commissioned. The distinction matters: we program new cards to your specification, not copy existing ones.
Encrypted credentials—HID Seos, HID iCLASS SE, MIFARE DESFire AES—cannot be cloned or sourced from any aftermarket supplier, including us. Those require re-enrollment through the original platform. If your community uses encrypted smart cards, this guide does not apply to your credential management.
How to Identify Your HOA Gate’s Card Format
Step 1: Find the reader model number. The reader mounted at your gate entry point almost always has the brand name and model visible on the housing. DoorKing 1815-series readers are labeled clearly. Linear readers show the Linear or IEI brand name. AWID readers display AWID and a model number like SP-6820.
Step 2: Look at your existing cards. Many OEM credentials print the part number directly on the card body. A DoorKing card often shows 1508-120 or similar. Linear cards may show 0-297401. The facility code is often labeled as “FC,” “Site Code,” or “S/C” on the card face.
Step 3: Check the gate system documentation. The access panel installed in your gate control box—or the original installation paperwork—should identify the card format and the facility code used.
Step 4: Ask the original installer. If you have any relationship with the contractor who installed the gate, the facility code is in their records. Most installers will provide this to the property owner on request.

What “Compatible by Specification” Means for Gate Cards
American Key Cards is not affiliated with DoorKing, Linear, IEI, AWID, Nortek Security and Control, or any gate system OEM. Our cards and fobs are compatible by specification: they use the same 125 kHz frequency, the same air-interface protocol (AWID for DoorKing and AWID-based readers, HID H10301 for Linear/IEI), and the same 26-bit Wiegand data structure as the OEM credential. They are programmed to the same facility code and card numbers.
What that means practically: when your resident presents our card at the DoorKing or Linear reader, the reader decodes it, sends the standard Wiegand data to your access panel, and the gate opens—exactly as it would with an OEM card.
What it does not mean: we cannot reproduce credentials that use AES cryptographic protection. If your gate system uses encrypted smart cards, the OEM platform controls credential issuance and we cannot help with those specific formats.
Why Non-OEM Gate Cards Cost Less
OEM gate credentials are priced to support a distribution chain: the manufacturer sells to a regional distributor, who sells to an access control contractor, who marks up the price again before billing the HOA. The underlying card technology—a small 125 kHz RFID chip in a clamshell or fob housing—costs a fraction of the retail price at any point in that chain.
American Key Cards sources card components directly and programs credentials to order. There is no dealer margin in our pricing. For an HOA replacing 50 fobs for new residents at move-in time, or a property manager handling a batch of 200 cards for a gate expansion, the difference per unit adds up quickly.
There is no performance difference between a properly programmed compatible card and an OEM card at the reader level. The reader cannot distinguish brand—it reads the RF signal and decodes the data. A card that outputs the correct facility code and card number on the correct 125 kHz protocol will operate your gate identically to the original OEM credential.
Ordering Compatible HOA Gate Cards and Fobs
The ordering process is straightforward:
- Identify your gate reader brand and model (DoorKing 1815-series, Linear eMerge, AWID SP-6820, etc.)
- Locate your facility code—on an existing card, in the gate system’s panel software, or in your installation records
- Decide on card number range for the new batch
- Choose clamshell card, key fob, or both
AKC programs each batch to your exact specification and ships ready-to-enroll credentials. No access panel reconfiguration is needed. New cards can be added to the gate system’s credential database exactly the same way as any other authorized card.
If you are unsure of your format or facility code, contact American Key Cards with your reader model number and any details from your existing cards or installation documentation. We will confirm the correct format and walk you through what information we need to program your order.
HOA boards and property managers who need to reorder gate access cards and fobs without going through the original installer can contact American Key Cards directly. Provide your gate reader model, facility code, and quantity, and we will program and ship compatible credentials to your address.
Frequently asked questions
What access card format do most HOA gate systems use?
The most common HOA gate credentials are DoorKing DKProx (AWID-protocol, 125 kHz) and Linear/IEI 26-bit Wiegand (HID-compatible, 125 kHz). Your format depends on the reader brand installed at the gate. DoorKing 1815-series readers use AWID-format cards; Linear and IEI readers use HID-compatible H10301 cards. The reader model number on the housing is the fastest way to confirm which format you need.
Can I order HOA gate cards without going through the gate company or a dealer?
Yes. DoorKing DKProx and Linear 26-bit Wiegand are both open 125 kHz proximity formats that can be supplied by authorized aftermarket vendors. American Key Cards programs compatible clamshell cards and key fobs to your facility code and ships directly to the HOA board or property manager—no dealer account required.
What information do I need to order replacement gate cards for my HOA?
You need three things: your gate reader brand and model (found on the reader housing), your facility code (sometimes called site code), and the card number range you want programmed. The facility code is usually on your existing cards or in the gate system's programming records. Contact us if you cannot locate it—we can often help identify the format from the reader model alone.
Can HOA gate fobs and cards be cloned, and is that a security concern?
Standard DoorKing DKProx and Linear 26-bit credentials operate at 125 kHz without encryption and can be duplicated with commercially available RFID tools. For most HOA applications the primary concern is authorized reordering, not adversarial cloning. If your community requires higher security, DoorKing and other vendors offer encrypted smart credentials—but those cannot be sourced from aftermarket suppliers and must go through the original vendor's enrollment platform.
