Hi there! I understand that the codes for your DDLock app are not working. To help you better, could you please clarify a bit more? For example:

- Are you trying to enter access codes on the physical lock or within the app?
- Is the lock not accepting any codes at all, or is it just specific codes that don’t work?
- Have you tried any steps like resetting the lock, checking battery levels, or making sure Bluetooth is connected?

Once I have a bit more detail, I can guide you through some steps to troubleshoot and hopefully resolve it quickly.

entering the code physically on the lock and none of them are working

Thanks for the extra info! Since you're physically entering codes on the lock and none are working, let's try these steps together to get to the root of the problem:

1. Check the Battery Level:
Low batteries can cause the lock to reject codes or become unresponsive. Please open the battery compartment and either check the battery indicator (if available) or replace the batteries with fresh ones.

2. Verify the Passcodes:
Are you certain the codes you're entering are correct? If you have a master code (usually default is "123456"), try entering that first to see if the lock responds. Sometimes codes get changed or need to be reset in the app.

3. Reset the Lock:
If codes still don’t work, performing a factory reset on the lock can help clear any software glitches or forgotten settings. Usually, this involves pressing and holding the reset button on the lock (refer to your user manual for specific steps). After resetting, try using the default master code again.

4. Test the Lock After Reset:
Once reset, physically enter the default master code to check if it unlocks. If it does, then codes should be re-programmed or synchronized through the DDLock app.

5. Re-pair the Lock with the App:
If you’ve reset the lock, open the DDLock app on your Windows device and pair the lock again via Bluetooth. Make sure your phone’s Bluetooth is on and nearby. Sometimes pairing issues prevent unlocking.

6. Inspect the Keypad:
Make sure the keypad buttons are clean and not stuck or damaged. Dirt or physical damage can cause button presses to be ignored.

If you don't have the user manual handy, I can provide reset instructions based on your lock model if you let me know which model it is.

Let me know if you have already tried any of these or need detailed steps for the reset and pairing procedure!

Are you satisfied with this approach so far?
