The right RFID credentials for a card lock management system depend on the lock’s frequency, card type, and enrollment process. The ETEKJOY cards suit compatible 125 kHz systems; the Dhiedas and 10-pack fobs are 13.56 MHz options; Lockly’s cards are designed for specified Lockly models; and the Sanpopo key fobs offer a larger batch of MIFARE Classic 1K credentials. Confirm compatibility with your lock before ordering.
| Product | Best for | Key compatibility detail |
|---|---|---|
| ETEKJOY 100-card pack | Compatible 125 kHz systems | Read-only; unencrypted systems only |
| Dhiedas 5 fobs | Small 13.56 MHz credential needs | Pre-programmed, read-only fobs |
| 10-pack RFID IC fobs | Compatible TTLock or Tuya locks | 13.56 MHz; verify the specific lock |
| Lockly 3-card set | PGD728FC and PGD628FC locks | Made for the listed Lockly models |
| Sanpopo 100 key fobs | Bulk 13.56 MHz credential needs | MIFARE Classic 1K; check system support |
ETEKJOY 100-Card 125 kHz Pack
Best for: Property managers or businesses that need a large supply of credentials for an existing, compatible 125 kHz access control system. The pack contains 100 cards, each with a unique pre-programmed ID printed on the card.
The cards are read-only and are described as compatible with universal, unencrypted 125 kHz formats such as EM4100 and EM4102. That makes them a potential fit when a management system enrolls credentials by reading their IDs and supports this card type.
Limitation: These cards cannot be rewritten and do not work with 13.56 MHz systems or encrypted formats. The listing specifically excludes Tuya and TTLock smart locks. Check the reader’s frequency and credential requirements before buying.
Dhiedas 5-Pack 13.56 MHz Key Fobs
Best for: Buyers who need a small number of pre-programmed fobs for a compatible 13.56 MHz RFID lock or access control system. The five-piece set can provide additional credentials for approved users where the lock supports registering new fobs.
The product is identified as 13.56 MHz and read-only. Its pre-programmed fobs cannot be rewritten with a card writer, so they should be treated as fixed credentials rather than blank cards for a credential-management workflow.
Limitation: The listing does not specify particular lock brands or encrypted formats. Do not assume that matching frequency alone guarantees compatibility; confirm the exact credential type and enrollment method with the system documentation.
10-Pack RFID IC Fobs For Smart Locks
Best for: Households, short-term rental hosts, or workplaces that need several credentials and use a compatible 13.56 MHz smart lock. The listing states support for TTLock and Tuya, as well as most 13.56 MHz smart locks and fingerprint deadbolts.
The ten-fob pack is intended for tap-to-unlock access and sharing with family, guests, or employees. For a management system, its larger quantity may help when issuing separate credentials to several users, provided the lock can register each fob.
Limitation: “Most” does not mean every 13.56 MHz lock. Confirm that the specific lock supports these fobs and check how it adds or removes credentials. The supplied details do not state whether the fobs are rewritable.
Lockly Smart RFID Cards, 3-Pack
Best for: Owners of Lockly PGD728FC or PGD628FC smart locks who want three additional access cards for household members, guests, or backup use. The product is specifically described as designed to complement those two models.
Unlike general-purpose RFID cards, this set has clearly named target lock models. That makes it the more direct choice when the existing lock is one of the listed versions and the goal is to add credentials without guessing at a generic card’s compatibility.
Limitation: The supplied details do not claim compatibility with other Lockly models or third-party systems. Check the model number on the lock before choosing this set.
Sanpopo 100 MIFARE Classic 1K Key Fobs
Best for: Buyers seeking a bulk set of keychain-style credentials for a system that explicitly supports MIFARE Classic 1K and ISO 14443A at 13.56 MHz. The listing describes 100 fobs, 1K storage, and a compact key-ring design.
The fobs are specified as ABS+PC and intended for access control and other RFID applications. Their keychain form can be convenient for users who prefer a portable token over a card. The listing also describes a 0.5–10 cm read distance, but actual operation depends on the reader and system.
Limitation: Frequency and chip family do not establish compatibility with every lock. The listing mentions copying only when the original is unencrypted; verify authorization and system support, and do not assume these fobs can replace encrypted credentials.
Buying Guide: Choosing Credentials For A Card Lock System
What frequency and card type does the lock use?
Start with the lock or reader documentation. A 125 kHz card and a 13.56 MHz card are not interchangeable simply because both use RFID. Also check the supported chip or credential format. The ETEKJOY cards specify unencrypted 125 kHz use, while the Sanpopo fobs identify as MIFARE Classic 1K at 13.56 MHz.
Can the system enroll and remove users?
A card management system typically needs a way to add credentials and revoke access when a card is lost or a user leaves. Ask whether enrollment happens at the lock, through an app, or through an administrator interface. Read-only credentials may still be enrolled by ID, but they cannot be rewritten as new cards.
Do you need cards, fobs, or a bulk pack?
Cards are easy to distribute as flat credentials, while key fobs attach to a key ring. Small sets fit limited user groups; larger packs may suit a site issuing credentials to many people. Select the form and quantity only after confirming compatibility, since an unused bulk pack does not solve a frequency mismatch.
How should you compare general-purpose and brand-specific options?
Brand-specific credentials can reduce uncertainty when the exact lock model is listed, as with the Lockly cards. General-purpose products may serve multiple systems, but only when the reader supports the stated frequency and credential format. Check model numbers, security requirements, and registration steps before ordering.
Frequently Asked Questions
Can a 125 kHz card work with a 13.56 MHz lock?
No. These products use different frequencies, so the lock must support the card’s frequency and credential format.
Are all RFID cards rewritable?
No. ETEKJOY and Dhiedas identify their credentials as read-only and pre-programmed. Check the product details rather than assuming a card can be rewritten.
Will any 13.56 MHz fob work with TTLock or Tuya?
Not necessarily. Frequency alone does not guarantee compatibility. The 10-pack listing states TTLock and Tuya compatibility, but confirm support for your specific lock.
What should I check before ordering replacement credentials?
Check the lock model, operating frequency, accepted card or chip type, encryption requirements, and the method used to enroll and revoke credentials.
