I purchased A-Star VXI in Dec, 2008 having chasis no. 104629. On 26th Feb, 2010 my family friend opened all doors of my A-star with his Santro key by mistake. Immediately I contacted nearest authorised dealer/service station of Atul Motors PVT. Ltd., Jamnagar. They are taking things very lightly and replied that all doors will opened but engine will not start. This is very surprised me. I have also contacted on phone with GM works. He is also surprised me with same answer. He tried to explain me that keys of 3-4 years old car may open the doors, I am also attended the free checkup camp at Jamnagar Nr. HDFC Bank on 07.03.2010 and same fact narrated to the person available at camp. They noted my car no. chasis no. and key no. and promise me to reply in two days this matter. Till date no response is received from dealer.
