Aravind,
These remote keys dont work on RFID frequencies but 433 MHz.
My Honda City has some RFID system in the key. They told me that it wont start with a mechanical duplicate key. I did make a duplicate and ground off the plastic so that I can keep in my wallet for an emergency. Trust me I have locked myself out many times!
Even if "they" opened the car they would not be able to start the car.. so dont leave valuables inside. I must also look for a care safe as I drive up and down to my coffee estate every week and stop for coffee or breakfast along the way.

Have to try it in a quiet place. I have not bothered probing deeper into it as XYL has banned any hacking into the car. First thing she said when we booked the Xylo " Now Listen. I dont want you to hack into the car. No wires criss crossing here and there, no probing / reverse engineering whatsoever" ;-)

We didnot work on Automotive RFID segment and that segments software required signing NDA's as it had some propriety encryption/decryption code.
