help key will not turn l322

hi i have got a range rover l322 04 reg and the ignition key will not turn . the batt is ok and all the fuses are  ok too . all so the srs light as came on  very dim on dash. all this happened at same time please help

Your battery is probably not OK, how did you test it and what was the voltage? That is probably why your SRS is throwing a code also, low voltage.
