Do our key fobs every lose batter? and I was told I believe that they charge by sticking it into the ignition? I have CA and rarely if ever plug my key in as it sits in my pocket but the other day I got a message on my car screen that looked like a key fob with a battery symbol or something. Can they be charged by sticking it in the car

 

Yes.

Need to put in ignition every now and then to charge.

 

I believe w/ comfort access it will not charge when you put it in the ignition. You can pop off the cover on the back of the fob and a small battery goes in there.

Cars without comfort access will charge when you put the key in the ingnition.

 

That's only standard fob - the Comfort Access key fob uses a replaceable watch/remote control type battery ... easy to find (Radio Shack, etc), no-fuss and cheap replacement; my primary fob battery lasted about 2+ years/

 

Standard key: Yes
The manual states you should use the spare key at least once a year.

Comfort Access: Yes but it has an interchangeable battery.

 

Does this charging apply to pre-LCI cars too? I had no idea.

 

Yea.

 

Thanks. Good to know.

So if for some reason I have to switch to my spare keyfob, I'll expect it to not unlock the car initially.

I'll have to do a test with that tomorrow, see if my (after-market) car alarm is turned off from turning the key in the door.

 

It should deactivate the aftermarket alarm when using the actual key hole.

 

Interchangeable batteries aren't rechargeable; hence, CA FOBs don't charge when placed in the ignition.
