Guyz,
I would like to share my experience with you. I lost only key of my Suzuki Baleno and seeked for help through normal electrician to start the car with ordinary key. It didn't worked even after so many efforts.
Finally I got contact of a duplicate key maker who demanded PKR 8000 and I agreed. He tried and found that the immobilizer is burnt due to previous work done by the electrician. Long story short...finally the Immobizer and ECU was replaced and new key was also programmed and it costed me 20K.
Conclusion:
At first take good care of keys with sensors and if loss don't try experiments. Just knock the right person otherwise you will be paying a high price like me.
Though it was tough but I learnt a good lesson.
