-If this card worked before in this vehicle
Then you have malfunction somewhere

-If not
Replace PCF inside and program card via diag.

did you open card and repair...and after that doesn t work or what ?
As i know ...where you program card to the car ...works together remote control and start car,so if car starts and remote doesn t work ....so you have problem with card....
Do you have another card ? if you have, on her works remote ?

Enjoy...

Led should flash while press any button. Check the card for rf broadcast. Take thin wire and make coil 2,5- 3 turns 1cm diameter, solder germanium diode (but 1n4148 can also works) in serial, and 10p cap parallel. Plug multimeter to the cap, get coil close to the hole upper the card, press button and you should see voltage on the meter.

If card is ok, then check central locking with button on the dash. If it's ok, I would look for the problem in uch. Also fuses to check.

THanks mates

Appreciate the cooperation of everyone, but I will not open the card to repair because in my country there is no way to find parts for replacement, very hard to find something extra parts to repair this genre "only if ordered by at yourself." But in this case I decided to order 2 key cards in Dealers.

But before you order 2 new keycards you must be shure that is problem in them,because many times happen that people order new and programm and again same situation,so be careful.
Do you have CLIP ? if you have it looks in parameters when you push the button on the cards what s happen,did he recieve signal(car-uch) ?
I repair hundreds of keycards of LAGUNA II,most problem is in switch which desolder and you only need solder again and also resolder PCF chip and then try and see what happen.
Before open the cards check with rf metter for signal to see is broadcasting freq or not.

Report what you do and how to solve problem and also if you have more question,ask
