Comfort Access Key

AltecBX · 01-30-2010, 04:32 PM

Keeps saying low battery. The dealer said that it charges by setting it in the slot. I have put it in he slot for the last two weeks when I drive, and sometimes when I forget, it warns me when I start the car. WTF
How long do I have to leave it in for to fully charge?

if you have comfort access, the key fob does not charge even if you put it in the slot. you just replace the battery. i believe it's cr2032...

Far as I know if you have CA it wont recharge the fob...thats only for non CA fobs. You have to change the battary. There are a few threads already on this subject

Yeah, that's what my SA's have told me, too... they are retarded, I swear. You can get the battery replaced under warranty at your dealership. I had that problem once, they replaced the battery, and it's been fine since then (going on 2 years with this battery).
