I'd suggest you put a new battery in it.

My 2013 key has a small slot near the top of the FOB, on the seam, that will open up the two halves by putting a flat tipped screwdriver in it and twisting.

:)

The car is totalled. You are done.

Or, maybe you could read the manual?

The photo shared is of an uncut key, which I doubt is the actual key used by the OP. The texture of the plastic is similar to third-party replica key blanks I've had experience with. The replicas typically will accept an original transponder/remote module, but can vary quite a bit in the actual execution such that the two halves aren't interchangeable with genuine parts, and sometimes even a genuine remote doesn't fit well enough to work correctly.

It wouldn't surprise me if this key (or the one the OP is actually using) is missing the recess for a screwdriver to wedge apart the halves. If that's the key, the halves still need to be pried apart, and a knife would be a better tool to start attacking the seam than a screwdriver.

Oh, be nice now - :slap:

:D

Yogi Berra, Buddha, or someone said (and I paraphrase): When you read the instructions, you get an education. You get experience when you don't.

That reminded me of a quote I just heard the other day.

"Experience is a bitch. The test usually comes before the lesson." :lol:

I don't have the manual
Thanks tho

My key does have the slot pictured in the helpful video.

Here ya go.

Wrong key type for FRS.
I have BRZ

Why does your profile say you drive an FRS?
Why have you not split the casing in half yet and replaced the battery?
Why are we still here

:iono:

:sigh:
