to let you know, i have a 03 bmw 745i non comfort access key. i have a main
one and a spare. first off this video does not work. i beyond carefully cut
open the case with a hot razor. didnt even see the front or have the main
board fall off the front of the half with the buttons. i saw the battery,
with was spot welded in 4 places on both sides, unexpected. got that lose
with a very small flat head. then put in this diy guys battery he names in
the more info. and wala nothing happened. this doesnt work and the other
battery prevents the fob from shutting. the rechargable battery in the fob
is half the width of normal. two if the car recharges the battery in the
key when u drive what is it going to do when it tries to recharge a non
recharable battery. possibly blow up or ruin ur car. NO NOT TRY THIS DIY IS
MORE THEAN MOST OF THE TIME WITH BMW A BAD IDEA. THEY MADE THIS SH!T SO
THAT YOU CANT GET AROUND THEM. THATS Y YOU PAY SO MUCH FOR IT. THEY TOOK
THE TIME TO PUT NEVER ENDING LOOPS IN THEIR PRODUCTS. YOUR WELCOME.

1 solderpoint is now ok, but trying to solder the other broken solderpoint,
the small solder part on the board came off and i cant find the copperlead
to make a bypass from the buttonswitch to the printed board. Any ideas?

sjaantje20 says:

managed to solder 2nd position (clos( button and it works:) Th 1st button (
open) gave a problem while soldering. 1 solderpoint ok, but tring to
soleder the other broken solderpoint, the part from the board came off and
i cant find the copper;ead to mak a bypass. Any ideas? Hennie from Holland

The battery is a vl2020 for most bmw key fobs…most models as well. The
design for our 7 series cannot be bought. BMWGM5 sells them with
instructions on how to retrofit them. Im ordering one on Monday

If you take it to a electronics repair shop they could fix it for you,
should only cost a couple bucks, as long as you have the case already
opened.

DIYsavecash says:

I’d love to, but I don’t have a comfort access key fob, those are pretty
easy, check out my technique in the video the key fob I have is the non
comfort access, unfortunately I can’t risk messing it up by cutting into it
myself, if the issue ever comes up I will for sure.

Can you, uh, actually show how to take the battery out and change it?

theory and practical. Double thumbs up for Mr. DIYsavecash. Thanks for the
