My SparkFun RTK Facet L-Band is not updating its keys, it only has 3 days left.

Do you have any sugestions?

Sorry about that! You have two options:

1. Doing a factory reset will force the device to dump its keys and get new ones.

or

1. Update to v3.5 or later firmware (currently v3.6: [https://docs.sparkfun.com/SparkFun\_RTK\_ … re\_update/](https://docs.sparkfun.com/SparkFun_RTK_Firmware/firmware_update/)). There was a bug in earlier versions that caused the key update routine to fail. But the initial key gathering works; that’s why #1 above works. If you erase the keys, the initial key gathering is triggered.
