Apartment & Multifamily Building Access Cards & Fobs

Who This Is For

This service is designed for property managers, condo board administrators, multifamily building owners, and individual residents who need replacement entry credentials for an existing access system they do not administer at the hardware level. If the readers and panels are already in place and you simply need credentials that work with them, this is the right starting point.

Residents who have lost a fob or need a spare for a household member represent the most common single-unit inquiry. Property managers ordering seasonal or move-in batches — or replacing a depleted stock — represent the bulk of volume orders. Both are served from the same format library, and reorder records are kept on file so repeat runs require only a quantity and shipping address.

Entry-System Formats We Cover for Multifamily

Apartment entry runs on a wider mix of technologies than most residents realise. The majority of North American installations use 125 kHz LF proximity in the standard 26-bit H10301 wiegand format or one of the many proprietary variants built on it. Indala-based systems are especially common in multifamily: the Indala ASC 27-bit and Indala Optus 34-bit formats appear across mid-size apartment portfolios managed with Lenel, AMAG, Kantech, and Keri panels. The AWID 50-bit format is prevalent in buildings whose access infrastructure was installed by RBH or integrated over a longer period.

Managed-access deployments — particularly Kastle-operated buildings — use the proprietary Kastle 32-bit credential format, which differs from standard 26-bit and requires format-specific encoding. European intercom entry is its own category: Urmet 1125/50 doorbells use a keyed token format, Noralsy panels use a specific badge protocol common across French residential buildings, and Comelit and Videx installations use LF fobs that are enrolled directly by the panel. We stock compatible credentials across all of these families and maintain format references for buildings that cannot easily identify their installed system.

For the full range of 125 kHz LF proximity cards and fobs as well as intercom and residential entry badges, the category pages list every format currently in the library.

Replacements for Residents, Bulk Supply for Managers

Individual residents typically need one or two credentials encoded to their existing card number and facility code. Where a resident can supply an existing working credential as a reference sample, format identification is straightforward. Where the credential has been lost entirely, the property manager or building administrator can usually provide the facility code and card number from their access-control panel, which is all that is needed to produce a compatible replacement.

Property managers running larger operations benefit from bulk ordering — move-in kits, floor-by-floor batches, or a standing stock held for rapid distribution. Our bulk ordering guide for installers and facility managers covers quantity breaks, format-file management, and how to structure a standing reorder so turnaround stays short. Format records are retained on file for each account, eliminating the need to re-specify encoding details on every subsequent order.

For adjacent residential applications such as gated community and HOA gate fob replacements, the same bulk-ordering structure applies, and many property management firms consolidate multiple sites under a single account.

How Compatible Credentials Are Encoded to Your Building

A compatible proximity card or fob is a blank credential — typically built on a T5577 or equivalent writable 125 kHz substrate — that is programmed to transmit the exact bit-string your readers expect. That bit-string is determined by three elements: the modulation and data-rate standard your system uses (for example, Indala FSK vs. standard EM/HID ASK), the bit-length of the wiegand output (26-bit, 27-bit, 34-bit, 50-bit, or a proprietary variant), and the facility code and card number assigned to the credential.

For smart-card formats such as managed cloud-access systems that enrol credentials via the panel rather than encoding them externally, compatible blank credentials are supplied to your format specification and enrolled by your system administrator using the panel's own enrolment workflow — no third-party configuration is required on our end. If you are unsure what format your building uses, our access card format identification guide walks through the most reliable methods, including markings on existing cards, panel model numbers, and wiegand output length. The compatible vs. genuine access cards guide explains the practical difference for buyers who want to understand what they are ordering.

EU intercom tokens such as the Urmet 1125/50 compatible token and Noralsy compatible badge operate on a different enrolment principle: the token is presented to the reader during the panel's learn sequence and the panel assigns it an internal ID. These tokens are supplied as compatible blanks — the building's panel performs the enrolment.

Request a Quote or a Sample

To request credentials, use the contact form and include the system brand and model if known, the wiegand format or bit-length if you have it, and the quantity needed. For bulk property-manager orders, noting your facility code and card number range allows us to pre-configure and ship without a back-and-forth. For residents who are unsure of their system, a photograph of the existing fob — particularly the chip-end — is often enough to identify the format.

Sample credentials are available for property managers and procurement contacts evaluating format compatibility before committing to a volume run. Samples are encoded to a test card number in your facility code and can be presented to your reader to confirm operation before the full order is placed.
