How to Import Unlock Certificates to the Phantom 4 RTK

After receiving your unlock certificate from DJI Fly Safe, you must import it to your done before you can fly. This article will show you how to import the unlock certificate using GS RTK for the Phantom 4 RTK drone. 


Importing the Unlock Certificate

After DJI approves your unlock request certificate, sync it to your remote controller and aircraft. You cannot fly in that airspace until you have synced and imported the certificate. 

  1. Power on your remote controller and aircraft. A WiFi connection is required to sync your unlock request(s). 
  2. From the home screen, tap on Fly
  3. Tap the three dots in the upper right corner to open the Aircraft Settings. 
  4. Scroll down in the Aircraft Settings to find the Unlock certificate list. 
  5. After opening the list, tap Synchronize to obtain the most up-to-date list of your unlock certificates. The App list organizes the unlock requests by flight controller serial number. Under that serial number are the valid unlock certificates for that drone.
  6. Tap Import Aircraft. The text will change to “Imported.” Then switch to the Aircraft list to confirm the unlock certificate has the correct date and time(s). 
  7. To activate the unlock certificate, tap the toggle switch so it is green.

Remember that only one unlock certificate can be activated at a time

If you have trouble getting your unlock certificate imported to your Phantom 4 RTK’s remote controller, follow the troubleshooting suggestions below.

Enter the Flight Controller Serial Number

Check that you have entered the flight controller serial number. This serial number can often be confused with the aircraft or RC serial numbers. Therefore, we recommend either using the DJI Fly Safe portal or saving this number so it is easy to find.

Note that DJI serial numbers always include the number zero (0) and never contain the letter O. 

If you make a mistake while typing the flight controller serial number, you will not receive any error messages or warnings and the unlock will not synchronize to your remote controller.

Use the Same DJI Account

You must use the same DJI account to apply for the unlock and log in on the remote controller for the certificate to sync.

If you work on a team with multiple pilots who each have their own DJI accounts, consider sharing one centralized DJI account to avoid problems with unlocking airspace. 

Keep Your Equipment Updated

Sometimes, flying with outdated firmware can cause self-unlocks to malfunction. We recommend keeping up with the latest firmware versions to avoid these problems.

Like firmware updates, DJI releases frequent updates to the Precise Fly Safe Database, which contains the airspace boundary limits for your drone. Check for updates to the Precise Fly Safe Database regularly to avoid problems when unlocking airspace.

Disable Unneeded Airspace Unlocks

If you encounter an airspace problem while on-site, check if any previous airspace unlocks are enabled. You can only have one unlock certificate enabled at a time, so turn off previous ones. 

You can disable aircraft unlocks by viewing the Aircraft section of the Unlock certificate list page and tapping the toggle switch on the right side of the screen.
