Jaguar S-Type 2005 Transponder Chip

[Jimbo56]

Hi All,
I purchased a spare transponder from E-Bay. https://www.ebay.co.uk/itm/384798212269
I have had the key programmed, however the transponder doesn't want to pair up using the `Switch to position 2, 4 times method'
I opened up and have attached the image showing spare chip on left and my existing chip on the right. They are different to the eye, however it may be that the one I purchased is more modern? Can anyone help with this?

TIA

Jim

HI

transponder is chip in key, remotes talk to door module.

new remotes can only be added with software like Jaguar ids/sdd

you cannot add remotes with any other procedure by pressing buttons or switching keys

all post 2002 s-type are like this

should of been programmed to the car when the key (transponder chip in key)  was coded to the car

cheers
