HELP: EWS Error and won't crank / start

My 2003 E39 525iT 140k miles won't start. It doesn't even crank.
I have checked the starter and it is in good condition.
Carsoft 6.5 show below error but I don't understand what is problem.

5 Schl?sel 5 nicht erkannt
Ablauf bei Schl?selidentifikation und Startvorgang
- Der Transponder im Schl?sel wird ?er die Ringantenne mit
Energie versorgt und sendet die Schl?seldaten an das EWS3-Stsuerger?.
- Das EWS3-Stsuerger? pr?t die Schl?soldatsn suf ihre Richtigkeit
und gibt erst dann ein Freigabesignal an Motorsteuerung mid Anlasser.
- Nech dem Motorstert erzeugt das EWS3-Steusrger? neue Schl?seldaten
(Wechselcode) und sendet Sie an den Transponder is Schl?sel


Please see attached screenshot or this http://i1213.photobucket.com/albums/...ps6052da4b.png

Please advise...
Thanks in advance,

The key is not recognized.

The process of identification of the key and the start up
- the transponder in the key will be powered by a ring-antenna and sends back the data of the key to the EWS
- the EWS checks the data and gives an enable signal to the DME and to the starter
- after the start the EWS sends new data to the key (changes the code)
