Benz sprinter W906 no-go

[madman47]

Hello all.
I have a WDB906633 sprinter that is no go.
I have two original keys, both are not recognised by the EZS.
I have star tester, and can communicate with EZS, no faults logged, checking the data, the EZS recognises a key inserted, but does not recognise it as the correct key, therefore will not release steering lock, cannot turn key, etc etc.
Also, the remote C/L buttons on the key do not respond (the red LED comes on, batteries are OK)

Can anyone please assist me with this problem vehicle?

Numbers on EZS are
A 906 545 65 08
A9065456508
114
ZGS001
0241

Thank you all!

w906 allways bad esl,use hammer, open and swap or buy emulator

Would bad ESL cause key not to tun in EZS? and no ignition lights? and no fault codes??

Thanks for the replies!

Key can't turn ezs can caused hash error ezs or key data corrupt.

Please make new keys on un-used position.
