how can i unlock my mercedes ml 350?

hae my friend, i had the same problem with my Ford Mondeo 2009 ST Model. because of electric systems and also because of the advanced engine specs, suddenly it got stuck, neighter its starting nor its giving any response. on the particular it just went BOOM. i took it to the nearest service station and they told me that the battery had damaged. just change the battery and check it out. it worked for me. i changed the battery and now its working perfectly. If you want to calculate the petrol with mileage, its according to your driving. well, my boss had ML350, i have noticed that it drink around 12.5 L / 100 Km.
