Lock Compatibility
Which key card fits your locking system?
Choose your system and the installation details you can confirm. Carry that information into a sample request, then verify the credential specification, authorized encoding and representative doors before ordering.
Key card finder
This selection starts a specification check; it is not a chip recommendation or a compatibility approval.
Step 1 — choose your lock system:
Step 2 — choose an installation detail you can confirm, or select “not confirmed”:
Selected installation / configuration
You can also describe your installation in the sample form, including when the model is not yet known.

MIFARE Ultralight® C (ULC) key cards
Classic 1K cards stopped encoding after a Saflok, dormakaba, Onity or SALTO security update? Compare Classic 1K, Ultralight C, Ultralight EV1 and DESFire, run five checks to identify the chip, and request ULC test cards.
Ultralight C (ULC) guideSaflok
dormakaba
Confirm the installed lock generation, encoder and active credential specification, including upgraded or mixed floors.
Compatibility detailsOnity
Honeywell
Confirm the installed reader and credential specification across existing, upgraded and DirectKey-enabled systems.
Compatibility detailsSALTO
SALTO Systems
Identify the platform and the credential families enabled for your property; the SALTO brand alone is insufficient.
Compatibility detailsVingCard
ASSA ABLOY Global Solutions
Confirm the lock generation, Visionline or Vostio setup, and the credential preparation required by the property.
Compatibility detailsKaba / dormakaba
dormakaba
Separate magstripe, RFID and mixed installations, then verify the reader and encoder specification.
Compatibility detailsMiwa
Miwa Lock Co.
Confirm the exact reader and whether the property specifies magstripe, contactless or FeliCa credentials.
Compatibility detailsTTLock & smart locks
TTLock / Tuya ecosystems
Identify the lock manufacturer and reader hardware. An app name or keypad alone does not establish card support.
Compatibility detailsTesa
ASSA ABLOY
Separate legacy magstripe, Tesa RFID and newer ASSA ABLOY-platform installations, then confirm the current credential.
Compatibility detailsCISA
Allegion
Distinguish legacy magstripe estates from eSIGNO and other CISA RFID generations; confirm installer-set options.
Compatibility detailsOmnitec
Omnitec Systems
Confirm the exact Gaudí, Slim, EVO or OS model and that the credential enrolls in your own Omnitec software.
Compatibility detailsHäfele Dialock
Häfele
Confirm whether the installation uses Tag-it (ISO 15693) or DESFire media; the two are not interchangeable.
Compatibility detailsOrbita
Orbita Technology
Confirm whether the reader is a current MIFARE model or an older 125 kHz T5577 line; the cards look identical.
Compatibility detailsBe-Tech
Be-Tech Security Systems
Confirm the Visual or current RFID series in use and separate any legacy magstripe floors.
Compatibility detailsHune
Hune
Confirm whether the reader is a current MIFARE model or an older 125 kHz line before selecting stock.
Compatibility detailsAdel
Adel Group
Identify the era in use: current MIFARE RFID, T5577 at 125 kHz or legacy magstripe, per building if mixed.
Compatibility detailsHow verification works
- 1
Describe the installed system
Share the lock and reader models, software and encoder, and any current credential specification. A brand or a photo alone may not identify the required card.
- 2
Agree the candidate specification
Confirm the chip or stripe, credential preparation and authorized encoding requirements with your system provider. Agree sample materials, fees and timing separately.
- 3
Check the sample in your property
Use your authorized encoder and test representative doors, common areas and any mixed reader generations. A print or material sample is a separate check from an access credential.
- 4
Record the approved specification
Document the sample result, artwork, material and credential requirements before placing a production order. Recheck when the installed system or configuration changes.
Compatibility questions, answered
Can this finder identify the exact chip for my hotel?
The finder records your installed system and the configuration you can confirm. It does not identify or certify a replacement chip. The reader model, active software configuration, encoder and any credential preparation must also be checked.
Can one card work across different lock brands?
A shared chip family alone does not establish compatibility. Each system may require different applications, security keys, credential preparation or authorization. For a mixed property, confirm each reader group and test the proposed credential with your system provider.
Can I order third-party cards for my installation?
Confirm whether your installed system accepts the proposed credential and whether its preparation and encoding are available through an authorized process. Support for a chip in a lock specification does not mean every card using that chip is approved or will work.
What should happen if a candidate sample fails?
Record the encoder result, the affected reader models and the steps tested. Ask your system provider and card supplier to review the specification before approving production. A revised sample plan may be needed; availability, charges and timing must be agreed.
Does changing the card material require another check?
Yes. Keep the agreed credential specification, then check the proposed card construction, thickness, antenna performance, durability and reader handling. An artwork or material approval does not replace an access test on representative doors.
Plan the next check for your property
Share the installed system, current credential information and intended sample test. We can discuss the specification, fees and timing for your project.
