Range Rover SC flat battery. can't get in the car now???

[Jamescmr2]

I have a 2006 supercharged range rover. I jump started a friends car last night and that coupled with the windscreen wipers constantly running (a problem which started on Friday night) has drained the battery. I tried to open the drivers door with the key this morning and it didn't work.

so, is there a way i can get in the car without smashing a window/front grill??

I have a tow bar fitted, can i put some power down there to allow the fob to open the car?


any help would be great

thanks

James
