I’ve had my car two years and I have yet to replace a battery in either key. My keys aren’t in a faraday pouch.
How far is your Porsche from where you keep your Key Fobs? Enough distance and the car and the Key Fob can't talk to each other the way they'd like to.

There’s probably 40-50 ft. between my car’s location in the garage and the key fobs located in one of my master bedroom nightstands (…right along with the keys to my bike and the spare key to my Corolla, which just recently needed a battery change after nearly 3 years). Does the 992’s PCM warn when the key fob battery is low?
So here are the latest additions to "REIN911" (all DIY indicated by asterik; with exception of removing/decoding active spoiler, tire upgrade and prime/paint DuckTail)
Clear Marker Lights* (Better total vehicle photos once WX clears in NorCal)
SunCoast Sport Spoiler Lip*
Zunsport Grille Protector*
OEM Exclusive Design Wheels on Michelin Pilot Sport 4S with Flat Six 10mm spacers*
GT3 Side Skirts* and TLG Mud Flaps*upfront (barely visible)
Numeric Racing Pedals*
DB Carbon Center Console Cover set*
Moshammer DuckTail EVO II, Clear Third Brake Light* Rear Reflector Blackout* (not seen)
Other modifications: PPF (full front), Window Tint (30%), Ceramic paint treatment, Frunk Mat,* Frunk Lid Liner*, Water, Oil and Fuel Caps,* all WX mats*
. . . . Does the 992’s PCM warn when the key fob battery is low?
Sometimes. It depends on how frequently I'm driving the car. If it's been more than a few days, the first warning I get is telling me something I already know. The time interval between first warning and dead battery is fairly short.

Be careful with this. I used my wife's Key Fob (of course) to try this. It did in fact shut the Key Fob OFF. But no manner of Button Presses or Button Press Combinations would bring it back to life. But Note: First, The Lock and Unlock button press commands worked just fine before I did this.Second, I was NOT getting a Low Battery Warning from the car before this and Third, Although the Key Fob was already OFF (or at least it wasn't working) repeating the Key Fob OFF function by pressing both the Lock and the Unlock buttons at the same time again, reliably generated the red flash illumination of the Key Fob Porsche Crest. So it was basically generating a redundant Key OFF command, or at least it looked that way.
So I tried removing and replacing the Battery. Essentially doing a Hard Reset. That didn't work either.
What did work was to replace the Battery with a new one.
It would seem that if/when the battery is near to, but hasn't reached the official Porsche "Low Battery" level . . . . it will still work just fine. But shut the Key Fob OFF and there's not enough left in the Battery to reboot the Key Fob. So-o-o-o-o-o-o I'd probably not do this, turning the Key Fob OFF, if I didn't have easy access to a new replacement battery.
