Hi,
I want to share my pinout for renewing keys without having to open them.
Everyone knows how much work it costs and how bad the opened and glued keys look ...

Scheme is for connecting the F series keys with HUF PCF7953 from the group:
434 HUF5663
434 HUF5767
868 HUF5661
315 HUF5662
315 HUF56XX

How to:
We need to solder 2 needles permanently to the yellow and white wires. It is important that the needles are very close together and isolated.
Remove the battery from the key.
Power (red) and ground (black) can be soldered to make it easier for us.
Put the needles at an angle of about 45 degrees and press firmly.
Click reset and it's done :)

When you remove the battery, it is printed on the board. Not sure if that helps your question.

Do the reset keys work? I once reset a key and remote stopped working. Can start car at steering but cant open doors. I still have the key. Will try a reset.

Molex Picoblade. I had the same question when I wanted to make myself a key reset harness with alligator clips and probes.

I got mine on Ebay. I think I paid like $4 for 10 of those connectors. I had to rearrange the wires for the correct pinout, but that's easy.
