Key Fob V70

I have an old, epoxy resined together remote key fob. Right old mess. Sawed and cut it apart.
Bought new empty key fob case from Ebay and transferred bits from the old one to this new bit of stuff.
Worked on unlocking and locking doors, but wouldn't start the engine.
Found out that there is a little immobiliser chip fitted into the top plastic part which holds the blade.
Frightened to gouge it out of the old wrecked fob, so hold it close to the key when starting; and hey presto, the engine starts.
However, I would like to get the little bugger (sorry, Chip;) out of the old and into the new fob without damaging it.
Does anyone know how delicate these little ****** are. If I lever it out with a screwdriver, could it be damaged, then cost me an aweful amount of dosh to fix it.

Might I suggest that you cut with care AROUND the chip, and then glue the plastic hunk with the chip imbedded in it to the inside of the new casing you bought? Keep away from where the battery goes, as you don't want to prevent battery installation, but up near the screw that holds the case together?

I started off as you suggested; junior hacksaw close to one side of the chip. Then filed away the plastic until very close to the glass chip.
From there, when I saw it was glass, I used a sharp stanley knife to shave off paper thin slices until the chip was released, intact. Was I chuffed.?
Of course, now I had a clean chip, it went in it's correct position to the side of the base of the blade.
It took around 3 hours! but saved a stack of dosh.
I rang the local Volvo dealer and informed them that they were wrong; the chip is not in the metal blade. Next time I visited them, they were all over me asking how I found that out, as they always thought it was inside the metal. Ha Ha!
Thanks again for your help.

DIY's are always fun but even better when you get to teach the dealer a thing or two!
