2032 Battery you need - amzn.to/3RhlY1N
Here is a quick and easy video on how to replace the dead / weak battery in your Tata Nano. All you need is a normal flat tip screwdriver and your new battery. Insert the screwdriver at the base of the fob and give it a good twist. Once you do that, you now have access to the dead 2032 battery. Push it out as I've shown and place your new battery + side facing upward. Clip the fob back together and check for your red light to work. You're all set! No need to reprogram your fob. I hope you found the video helpful!
