Successfully changed both batteries this morning thanks to the great information posted here. The pre-heat process is certainly a benefit as is using a very small screw driver in the tiny slot on the right side of the case. I used a toaster oven set on “Warm” for about 10 minutes to get the desired heated state.

Looking forward to a drive now with that potential 8-10 HP boost! Cheers!

Does anyone know if this will void the warranty?

Less than 90 days since last reply so I guess I'm safe to post

After 5 years and 5 months the battery in the main FOB for my 08 died today. I popped the hatch with the key and the alarm sounded. I would have thought using the key would have turned the alarm off. Oh well, grabbed the second FOB and was off.

Took all of about 3 minutes to swap my battery. Got a tiny jewelers screwdriver in one side and just ran it down the slot. I just happened to have a new CR2032 but now need to swap the other as I'm sure it is ready to die.

Trust me when I say I am NOT a MECHANIC but I changed both of my while sitting in parking lot at drug store very easily . Was surprised I could do it that easy. Think I used a dime to open them, one had never even been used since car was new

I have the older model. No problem prying open and changing the battery. However, I cannot get the two halves to click back together.
Is there a trick to that?

Thanks for the advice. Worked great for me.

The comment from the Chevy dealership when I bought the battery was "Those are a pain to change".

I don't understand why they think they are allowed to make negative comments about their products. These are now $60k-$70k cars; maybe Corvettes should be moved from Chevy to Caddy where there is more focus on customer satisfaction.

PHulst

No offense, but I think the dealership is dead nuts on.

I don't understand why they can engineer a $60000 automobile that works so well yet make it so exceptionally difficult to change a $2 battery. My 2003 GMC pickup takes only seconds to swap fob batteries.

Oh, and some Caddys have the same crappy remote fob.

Rub a little silicone lube (or whatever you have) on the rubber gasket. Put some masking tape on the jaws of a pair of pliers and squeeze the case together until it snaps shut. Or breaks.

cclive

Lubrication on the gasket is key to an easy reassembly...just as heat is important in the opening of the fob. Heat gets more important as we get towards winter...people always crack plastic on these cars in the winter and much less in summer.

And the key is a little lube, not gobs of it.

DonOH

They also said the older Chevy fob was an easy swap too.

PHulst

Yep, same one as my 2003 GMC truck.

Tiny screw driver worked for me! Also a credit card is easier on the plastic, I used the card to slide it open after I pried it with the screw driver on the right side where the gap seems a little deeper (below panic/horn button on the side). No marks in any of the fobs, they still look new

P.S. Remove the key first

I throw my down on the cement floor..Opens every time....

I could not get the small screwdriver approach to work without scratching/marring the case. In an older post, someone suggested to pull the key out just a bit and then gently turn it. That approached worked well for 4 Fobs so far. But I agree, a very poor design!

Cherokee Nation

That way or use a quarter..

Maxx

The credit card trick worked good on all 4 of my remotes (2/'07 & 2/'09)...

While I was in there I popped the little "contact titty" off the panic alarm buttons in the 09 (new) remotes and cut the same thing off the 07 (older) remotes!

No more setting off the stupid alarm with the key fob in my pocket!

That was going to be my question, I am always hitting the wrong button when I reach into my pocket to open the hatch and wanted to know if the alarm button could be disabled. I tried to open mine to investigate with a small screwdriver before looking at this post and it started making a "crackling" sound and I was afraid I would break it.

Thanks Chris, will give it another go

Danny T

the credit card worked and was just a matter of putting a piece of tape over the contact point on the surface that pushes against the panel to disable the panic button.

Thanks again,

Good info everyone, and I know I'm digging up an old one here but I found another potential issue in completing this task now that many of these cars are not under the original owner, as with my 2 week new-to-me baby. The previous owner may have screwed the pooch on his battery change, broken it, then super-glued it back together. That was the experience I had today. It was super hard to separate one side and then it never stuck back together and it looks like there is some glue residue there.

Best thing is a large Butcher Knife, I changed the battery in both of my FOB'S with no trouble or damage in less than 5 minutes
