IEI / Linear 26-bit Proximity Compatible Cards & Fobs
The garage-door giant's access line: Linear and IEI systems — from eMerge panels to apartment gates — run standard 26-bit Wiegand prox on the common reader protocol, making replacements a straightforward programming order.

Linear reached access control through the residential gate-and-garage market, and IEI brought the keypad heritage; under Nortek the combined line powers thousands of apartment complexes, small offices, and gated communities. The credential story is happily boring: standard 26-bit H10301 on the widely deployed Wiegand-class prox protocol, meaning the cards and fobs interoperate with the broader ecosystem of conforming readers. When a property manager runs out of the OEM-numbered stock (0-297401-style cards, 830-00420 fobs), the replacement is a compatible credential programmed with the same facility code and the next block of card numbers. That's our specialty: unbranded, compatible-by-specification cards and fobs, programmed and structure-verified before shipping, that enroll in eMerge and legacy Linear/IEI panels exactly like the stock they replace.

View compatible cardsIEI / Linear 26-bit Proximity — FAQ
Are IEI/Linear proximity cards a proprietary format?
No — they carry standard 26-bit H10301 data on the common Wiegand-class prox protocol. That's why correctly programmed compatible stock enrolls exactly like OEM-numbered cards: the panel reads facility code and card number, nothing brand-specific.
What facility code does my Linear system use?
It's in your panel or eMerge software's credential settings, and usually printed on existing cards. If neither is available, photos of a working card typically let us decode it. We confirm the code and your number range before programming a batch.
Will your cards work on a Linear eMerge Essential or E3 system?
Yes — eMerge platforms accept standard 26-bit Wiegand credentials from their attached readers. Programmed to your site's values, compatible stock enrolls through the normal eMerge credential-add workflow.
Can you match both the cards and the keyring fobs?
Yes, from one specification — the 0-297401-style cards and 830-00420-style fobs are the same format in different bodies, and we supply compatible versions of both in a single sequenced batch.
