This is pretty simple for many … but I will post this for the benefit of those who can appreciate the simple detail

Push the key-release tab to release the key

Locate the hole that the key inserts into ...

With the end of the Key, you can insert it into the fob and
carefully wiggle to pry two fob halves apart.
Then use your fingers to pry the two halves completely apart.

The Battery is held in with tabs. Carefully pry out the battery with a screwdriver.
I found it best to pry the battery from this tab shown in the photo below

The Key release tab may detach
when you pry the two halves
apart. Note the Spring and a hole
for it on the Tab. You will need
to align them to clip it back in.

The Tab will stay in place when it
is fitted correctly

if parts come apart on you,
This is how these two align.
There are some rubber tabs
that will assure alignment.
They are the 3 clear circular tips
that you see in the first photo below

Carefully align the key release
tab into the slot BEFORE pinching
the two halves together.

Test that you can push the key
release tab and that it operates
correctly before putting your
key back into its slot. Then it’s
OK to put the key in ... retest
releasing the key ... and you are done.
😁👍🏻

I found that relearning the Fob
with the Corvette was not necessary
after replacing the battery.

This is a good way to break the case. You're not cracking it dead centre, it's going to break, and cost you a new one, opening it like that.
Every mfg's fob with a built in key makes it simple.
Take the key out. Notice 2 or 3 small rectangular or squares. They fit the top of the fob with the key running on the outside of the fob. Insert it so it fits, and turn it sideways, that cracks the fob case. Proceed with jack knife, or small screwdriver.
*fyi only*
If you don't see how it works, I'll post a pic tomorrow.

Thx … it's just that I would never ever pry with a screw driver or jack knife
they can easily blemish the sides (plastic) … and that would ignite my O.C.D.

My fobs actually snapped right back together without a hint of them even being opened.
This method I used worked … one fella even did it this same way on a you tube video.
Boy some of those you tube screw driver methods might result is a bandaid being needed too.

and not saying there is only one way to do it of course … to each their own.

I was just putting more pictures and words to the process as the
books can be rather brief on what one might be facing
on what turns out to be a pretty simple task as a few parts can
fly around if one just quickly pops this remote open …
Cheers

I also deal with ocd and I'd lose it if I scratched it etc......just need something after it's cracked.
Nice to see in the manual. I'll never do it like that tho.
To each their own.
Spence did a hell of a good picture explanation for those of us who not so mechanically inclined. Almost makes me want to take mine apart just for the hell of it.

C'mon man. You haven't had to take it apart yet to swap a battery?
I don’t think my thread needs to take this tone - if I’m taking the sarcasm correctly.
I’m pretty sure there are people who have not replaced a remote battery.
I'm not above anyone to admit that I have not until yesterday.
So I took the time to take photos and post this thread to perhaps give those the confidence to do it too.
This instead of a GM Tech to do it at the Dealership as the manuals are notorious for minimizing explanation.
Hoping for others to have the same success to not blemish the fob in the process - as I know that may be a
prime reason for some to perhaps not even taking this task on.
For those who know everything about the key fob, please just ignore this thread.
For those who know much less, I hope this thread keeps you from having to ask.
I will say, it’s easier to do a second time, once done.

I actually made this thread in the process of resolving start-up problems
on two Corvettes in another thread.
I will stop my DIY at the point of dismantling the engine though (sarcasm)
😂

And you did one hell of a good job Spence.
Don't know if I would have had the patience to take all the pics.
Great detailed description.
