I got in the car today and there was a key symbol and the gas tank thingy. I'm assuming it means my key battery is going to run out soon so I was wondering how I can recharge it or if I have to replace it.

 

You are going to have to replace it. I don't know if you have the same key fob as I do. but at the bottom of the key fob if you take out the smaller key there's an indentation you stick a flat head or something like that in there and pry it open. Its a button battery easy to replace.

 

Alright cool. Do I have to go to the dealership or can I buy this at a place like China Mart or Radioshack?

 

Radioshack...CR2032 battery.

 

Yup CR2032. Buy two and keep one in the glove compartment.

 

yea, i just bought 2 of them for like 6 bucks...

 

Hate to bring this back from the dead, but can't you just plug it into the manual start slot over by the hood open latch?

I stuck it in there when it was saying that the battery was running down and it charged it up for me.

 

That's not a charger. All it does is let you put the immobilizer chip in close proximity to a sensor when the fob doesn't have enough battery power to communicate remotely.
If you open your fob you'll find a CR2032 battery (not rechargeable).

 

Hmm...that's strange though. Because I can honestly say that after the car told me my key fob's battery was low, I plugged it in there for a few minutes and it hasn't bothered me about it in about 3 months.

 

They don't necessarily quit all of a sudden, they can act flakey for quite a while when the battery gets low.
Two minutes, a couple bucks and you're good for two or three years again.

 

my car has been saying low battery for almost a year lol
