Reasons Why Your Nissan Qashqai Key Fob Won't Work The Qashqai has a distinctly SUV feel to it thanks to its larger dimensions. Moreover, the ride on 19-inch wheels in Ti and ST-L models may be a bit spongy at times.

Before putting the new battery in place, make sure there is no water damage or dirt on the terminals. If so, clean the terminals using some isopropyl ethanol.
