Knob is new and this total includes parts and labor. Didn't ask the cost of knob itself. In this official Suzuki workshop, some stuff is actually sold in full set like pair of wing-mirros, etc. So I suspect they charged me for both knobs.
The thing related to Diggi I had to purchase from an outside spare parts shop and then get it installed from the Suzuki workshop. In Suzuki workshop, only the full set of 5 doors locks and accessories is available which is of Rs. 1100. In such cases the anonymous shops selling spare parts are handy but then their parts are not genuine and may only last for few days. The 830 Rs. total includes 130 Rs. cost of Diggi lock I purchased from outside.

Actually my brother got the stereo installed. I defenitely kicked his butt when he arrived back to show me his karnama.
