Try the central locking button in car 1st. so not a problem with car rather than card !

Laguna 2 can be a three button card m8 or two button.. Which one ??
Try to match central locking first before you replace anything on the card (if card already have some missing components you must rather replace and code to car )

Yea swapping the chip if you have good spare key will start car and operate the central locking if cars central locking is ok

You could open up the card(VERY CAREFULLY!!) and make pictures of top and bottom of the PCB,I have almost every card,and can tell you what to replace if something is missing.
