Why This Matters

Key fobs (also called RFID cards) give your members and staff a physical way to unlock doors without needing a phone or passcode. This article walks you through adding a fob to a lock using the TTLock app.

Prerequisites

You must be using the TTLock integration with Wodify. To confirm, go to Automations → Smart Devices in Wodify and verify that a TTLock account is connected.

If your integration is active, your locks are already set up — just make sure you have the TTLock app installed on your phone and your physical key fob / RFID card in hand before starting.

How to Set Up the Key Fob

1. Open the TTLock app and tap the lock you want to add the fob to.
2. Make sure Bluetooth is enabled on your phone, then from the lock detail screen, tap Cards.
3. Tap + Add Card at the bottom of the screen.
4. Choose an access type:
   1. Timed — access only during a specific time window
   2. Permanent — ongoing access with no expiration
   3. Recurring — access on a repeating schedule
5. Enter a Name for the fob (e.g., "Rich's Key").
6. Tap OK. The app will show "Connecting with Lock. Please wait…" — hold the fob close to the lock during this step.
7. Once you see "Operation Successful", the fob is added and will appear in your Cards list.

Picking a Key Fob

Most modern TTLock smart locks use the 13.56 MHz High-Frequency (HF) RFID standard.

When shopping for fobs, make sure the product is compatible with both TTLock and this frequency — an incompatible fob won't be recognized by the lock.

The easiest way to find compatible fobs is to search Amazon for "TTLock 13.56MHz RFID". 

Look for those exact terms in the product name to make sure you're getting the right type. They're typically available in key fob, credit card, or sticker form — all work the same way.

FAQs

Q: "What access type should I choose?" A: Permanent is the most common choice for staff or long-term members. Use Timed for temporary visitors or trial members. Recurring works well for members who only need access on a set schedule.

Q: "The app says "Connecting with Lock" but nothing happens — what do I do?" A: Make sure you're within a few feet of the lock and that Bluetooth is enabled on your phone. If it still doesn't connect, try again.
 

Q: "How do I remove a fob?" A: To remove a Key Fob, you can head to:

1. Go to Cards from the lock detail screen.
2. Tap the card you want to remove.
3. On the Card Info screen, scroll down and tap Delete.
4. Tap Delete again to confirm.
5. You'll see "Operation Successful" and the card will be removed from the list.
