Some years back the keys of my Swift were left inside the car at my school(12th standard days), various students and even teachers tried their hands on the car but no use. At the end I followed my patented technique and the car was opened within a minute.
A teacher was busy scratching glass and his head with a metal scale and all of a sudden he heard a thud..eh, I broke the rear quarter glass using a brick and the teacher was looking at me with his eyes and mouth wide open.
Put my hand and stretched it to open rear door and car started doing "bho-bho", opened front door..took the keys and drove back home.
SIMPLE IT IS and this technique is applicable on every car, really. I have tried it once more on an another man's car and it worked perfectly.
