That's a predicament you're in

I don't think there is a way to bypass the key card.

If the card isn't been detected it's a fault on the round black coil inside the key card, probably one or more of the three solder joints on it have cracked.

Give this a try.... https://www.youtube.com/watch?v=-hs1prW6Ct4


If that doesn't work I would take my time and cut the card open, there are videos on you tube showing how to do this, study a few of them so you know what you are doing, make sure just to cut in a little bit don't put the blade in deep as you don't want to hit the circuit board.
With the card opened up you stand a much better chance of finding someone who could solder the coil contacts for you if you can't do it yourself.
Alternatively you could try and wedge the coil to make a contact and tape the card back together as a temporary measure.

You can buy new replacement card covers on ebay so it's not the end of the world if you mess yours up a little when cutting it open.

Hope you get it sorted.


Cheers.

Ok so I've opened up key card and all looks fine but just to be on safe side I redid the solder on the 3 joints still not working opens car fine and locks it but that's it

[joe12]

In my experience of the cards soldering the 3 joints always fixes them!

If the card was working as in starting the car then all of a sudden it's not working, (not being seen by the card reader), it is always a broken joint on the coil contacts, and I've fixed a few of these cards.

I suppose the coil could be defective but that is very rare.

Watch this video below from 3:16 and you will see that the guy is repairing the very thin wire from the coil, maybe this is your problem.

This video shows the coil solder repair with a little more close up detail.
