I’m looking at buying a complete new key fob (including transponder) from eBay or AliExpress, but a bit confused with which one I need.

I understand that mine is 433mhz, but there seems to be different style chips. Eg PCF 7941

I’ve attached a pic of my pcb.

Anyone have an idea or link to what I need, please?

Hello mate the problem I've had with a new key is getting the correct chip
The one I need is ;
Pcf 7936as
D8ye00039
Dn06370
There's plenty chips out there but I can't find this chip or any info on an updates or replacement
Being an 07/09 model it's seems to be the hardest one to replace/reprogram
Let's know if you progress further
Cheers henda

Ok.

How did you find out which chip you needed? 2007 3.6 TDV8

Lift the chip out of its location and it's written on the side
I've even thought of locating the chip on the ignition barrel and just using the keys as remotes
