With setting up the new beta fob I am presently using/evaluating, etc., I mentioned in my last post, (it sure is so so small in comparison to the AJT Fob)...... ...... ...... I once again, found myself removing the RFID chip from a stock JL fob.
I have removed the chip from 6 stock fobs so far. Anyway, I have damaged no stock fobs while pulling the chip. I will admit the last one I did a few days ago, did make me work at it so to speak.
Anyway, I do not use a utility knife.
I keep in mind that the RFID chip is pretty stout, but it can be damaged/rendered useless if you cut into it or pierce it. So, I do not use a utility knife.
What I do is to take a thin but somewhat wide flat tip screwdriver and carefully drive (using a small mallet to tap firmly, on the handle of the screwdriver) it between the chip and the wall of the stock fob. When I do this the wall gives/spreads and then I can very carefully pry the chip up an out. The RFID chip has no problem handling the pressure of the screwdriver blade against it.
With mine, I used a small screwdriver used for eyeglasses and it still couldn't get in. However, as I said, I was able to get the chip out without damaging the chip. But I did need to damage the original key fob cover.
