“Hotswapping” Dexcom G6 Transmitter

I’m using a Dexcom G6 and I applied a new sensor yesterday while in a rush and forgot that I needed to pair a new transmitter. I went to start the sensor and got a “pair new transmitter” instead of “new sensor” alert. I had already inserted the dead transmitter into the sensor cradle. Whoops.
I’ve heard of the idea of swapping a transmitter without having to replace the sensor as well. Is this possible? Any tips? I’m not sure how to do it and I’d hate to waste a perfectly good sensor.
Thank you

I think I’ve done that successfully, and keyed the new transmitter number after the fact. But if it doesn’t work call Dexcom and ask for a replacement.

Lise @6yGodsGr it definitely IS POSSIBLE. Last Saturday I had a “Signal Loss” error on both my t-Slim x2 pump [my principal receiver] and on my Dexcom phone app that I also use. After an hour of signal loss, after doing restarts on both devices, I figured that the Transmitter failed during its 72nd day of use, so I swapped it out and replaced it with a new transmitter while keeping in the sensor. I expect that this good sensor will give me a full 16 days service.

I used on of the tools of my Swiss Army Knife to pop out the failed transmitter, cleaned the new transmitter with alcohol and inserted, entered the new serial number, paired, entered sensor code and everything is working fine. One caution, you must wait more than 20 minutes - so I’ve been told - after removing the old transmitter. That 20 minutes may not apply if the old transmitter has failed.

Interesting, I opened your post while talking with Dexcom; a replacement transmitter and new sensor are being shipped.

hi @6yGodsGr just like @Dennis said - the transmitter can be popped out, you need to carefully use a thin tool at the spot where the transmitter is held in place. Most people use a test strip.
I’m attaching a picture of where the tabs are

There are YouTube videos out there that show you the steps to remove the older transmitter / replace

Great, thank you so much!

Forget the slim tools and the fixes. Call Tandem and they will fix you right up. We all make mistakes! They have helped me many times.

Getting one “free” from Dexcom is ok if you don’t mind inserting a new sensor, throwing away a good one AND the insertion appliance, ordering a replacement with their webform, wait g a day for their two email acknowledgement agreement to replace, a shipping confirmation the next business day, then waiting a week for the replacement to arrive. I’d only do that if the site was bad.

When the site/sensor isn’t bad, I use an unused stainless steel feeler gage to pop out the transmitter. It’s from a set I bought years ago for adjusting car engines . Like this one; Robot or human? There are less expensive versions.

It works perfectly. It’s a great time saver if I take a shower and want to verify that no humidity condensed between the sensor and transmitter, or I need to change transmitters for any reason.

I use it every time I change sensor sites, because I install the new one before removing the old. (I do peel off the old overpatch first.) Doing it that way makes it easier to systematically move to the nearest adjacent site without getting too close.

Good to have the instructions - thanks to those who shares them.
I know you can order replacements online - I tried it once but prefer doing it by phone. I’ve found that to be quick.
