1997 BMW 540i ews problem

[spanaz1]

Hello Friends,
I was trying to read ews 3 of BMW 540i using Carprog and unfortunately the data was lost. Now the car can't start and I can't program key.is there anyway to retrieve the ews data or can I do immo off or is there anyway to get the car started?
PLEASE HELP!

for future generations EWS3
Data location:
Motorola processor
MC68HC11EA9
Maskset:
2D47J (secured) carprog not, xprogm is ok
0D46J (unsecured) carprog is ok
I think the immo off faster

Is it possible to immo off?
