Hey all,
I have to replace with a new key battery every 3-4 months. Not a major issue, but it's a bit inconvenient. Chewing through a lot of batteries. Anyone else having this issue?

Stop buying Dollar Tree CR2032 batteries. Only get the Eveready or Varta replacements...

Mine ('06 CTTS) last about a year (w/Kessey). My Audi ones last 5yrs???

I've been using this off brand called Duracell. Ever heard of it?

Yea that's not normal. Every other car I've owned the battery easily lasts a few years or more. I guess this is just a Cayenne quirk?

Varta replacement last longest...dunno why.

Good to know, I have the same problem, Ikea and Dollar Tree Will try a better one.

volt meter. use it. battery life is directly related to voltage. also age. batteries like these are OLD and its difficult to find ones made recently that have a decent charge. keep them refrigerated when not used.

batteries plus has two different batteries they sell one guaranteed for a year plus the other with no guarantee. I bought mine there first the no warranty, it lasted a year, then the warrantied one, it is still going after two years!

3-4/mo is definitely not right. Do you have the 2nd keyfob you can use?
Any chance the keys are getting accidentally pressed in your pocket throughout the day?
Any water damage to the keyfob that could have caused some corrosion on the PCB?

I will inform my wife that part of the fridge will now be occupied by spare coin/aa/aaa/d cell batteries we have. I'm sure that'll be received well.

Also, not sure about your universe, but here on planet earth, freshly made CR2032 batteries are readily available. Recently picked up a bunch at Costco - it was that off-brand Duracell crap the OP mentioned.
