nakedmolerat:gundar:Satch: I'm not interested in replacing any of the electronics in my car. I just wanted to replace my existing key with one shaped like a credit card.
These two points are in conflict.
Your press button uses a radio signal and receiver the smart card uses a chip that requires a reader. They are differnet types of technology and different hardware
You don't quite understand the OP.
OP car uses proximity keys. He doesn't like his current proximity key as it is bulky. He just want a new proximity key that is thin enough to be left in the wallet.
Thank you, thank you! I was starting to wonder if my skill of written English was failing me!
As blakamin said, the buttons on the key remote are simply to unlock it from a distance, otherwise both of my cars sense when their keys are close (50cms and closer or similar) and allow unlocking by just pressing a button on the car's door handle.
I always have my wallet on me when driving (need my drivers licence) so having something in my wallet would be uber convenient!
