1997 V70 AWD 2.5t lost keys!

[Conor Flynn]

HAve lost the keys and fob to the above car...! seeing though it has been locked on the fob it has deadlock! we have tried "breaking in" as in string and wire on handle and knob etc, nothing works! we believe to have a spare key in the car so if we can get in some way that would be brilliant? any ideas, bridging wires etc?? thanks
