Just wanted to know everyones experience with new keys (with the diamond head) not from the dealer....
My key fob stopped working, so I purchased a CR2025, cut the fob open, put the battery in and the fob now works!
BUT, when I try the rechargeable battery (CV2020 I believe) in, after driving around for about a half hour or so yesterday, the fob doesnt work..... I dont think the battery is being charged. Anyone else have this issue? I'm ok with using a regular battery since the replacement fob is designed to be opened and closed.

You have an E60 right?
Can you list up your year?
I have diamond keys on all 3 of my cars and I have gotten new "shells" with blank key and used the top part of shell and a new rechargeable battery and had no issues.
You will have to reprogram both keys after you swap insides or replace battery without a jumper.
However, if you have an E60 I would like to know how you've done so.
If you cut a blank blade I would like to know how you've done this.
Also, I would like to know how you were able to sync the chip inside the blank keyblade with your CAS module.

Has anyone bought a used key from ebay like above^?
I assume you would still need the dealer to program it for comfort access etc?
I have my key but my fob is cracked and was wondering if this is the way to go.
