Replace battery

Same message.I'm holding off changing that battery until I figure this out.
I tested the battery with my multimeter.They're good.
How is that possible?The RKE without the new battery is in the house. If you don't know an answer it's ok to say I don't know or not give a guess at all.No offense intended.

If that RKE in the house is within about 30' of your car, they can still communicate. If you want to rule out the battery in the house without replacing the battery, take the battery out. The car will recognize only one RKE.

What does "Red" mean. Most meters with colored scales show green when good, red when less than adequate.
Hey Bugssy....
the inexpensive red/yellow/green testers can be misleading, a dead battery can read 3 volts but not have any "ooomph" happens all the time on 12 volt car batteries, you need one that load tests the battery. Best bet is to go to a battery store and purchase a different brand name one - or have them test it and see what happens..
a alternative is if your partner uses battery powered candles or other devices that that the same button
I work in IT and PC's take the same battery, we get lots of crappy ones from amazon - there is a secret code on the package that tells the expiration date

That is a 3 volt battery. If it read .3 (3/10) volts as you stated, it is nearly dead. And as @Tripwire said, batteries must be tested under load. Even if it read 3 volts open circuit, voltage may drop when current flows.
I don't have a dog in this fight, but no more than new batteries cost, I think that it would be somewhat silly not to go with new batteries in both remotes at the first sign of a failing battery. Otherwise, it is very possible that you will be in the middle of nowhere when the car fails to start and you are forced to empty the console and fine the little indentation for the RKE and hope that the existing battery has enough juice for just one more start so that you can get home.
Hey bugs...look at this? make any additions lately? its bad enough issue that GM released a TSB just about this

Key fob or driver presence module location?
Hi. I have a 2013 CTS4 coupe. I'm getting the electronic key not detected message and I have to put the fob in the little slot in the center console under the armrest to be able to start the car. I think it is whatever module that controls the sensor that can tell if you have the fob in your...

Agreed...I changed the batteries in all FOBs for my three vehicles just a week ago. Immediately noticed an improvement in operating range.
