UPDATED: January 2021. I will update if this method no longer works for me. Dexcom often changes certain things to make methods no longer effective.
I want to mention a few things before sharing how I restart my sensors. Please do this at your own risk. The G6 is FDA approved for 10 day wear only and it is possible that the sensor isn’t as accurate the longer you wear it. I extend my sensors at my own risk, and so should you. Additionally, I’ve extended mine successfully, but of course cannot guarantee that yours will.

Here’s how I restart my sensors (using the Dexcom app with an iPhone):
- Let your sensor expire, or plan ahead and end the session early.
- Use a test strip to pop the transmitter out of the sensor. Put the test strip between the shell of the sensor and the transmitter and work around the area that naturally bends when the sensor is removed.
- Wait about 20-30 minutes before reattaching the transmitter. Do not get the exposed sensor wet!
- After 20-30 minutes, reattach the transmitter.
- Start a new sensor and chose “with code”. (Choose this only if you have the code for the sensor you are wearing. Do not enter a code from another sensor or make one up. If you do not have the code, choose “no code”. You will need to calibrate with this option, but the sensor will still restart.)
- The sensor will warm-up for two hours and start giving readings again.
P.S. Did you know you can request FREE adhesives from Dexcom? I usually add one around the 10 day mark to help my sensor stay on longer.
