Frequently Asked Questions
Where is the EWS3 box located?
Usually behind the glovebox or in the driver-side footwell/kick panel depending on model. It's a small grey/black module with a single connector — send us your reg and we'll confirm.
Do I need to send the DME as well?
Not for a straightforward spare key. If the EWS has been swapped, is virgin, or the ISN needs matching, send the DME too so we can align both.
Can you reuse blocked key slots?
Yes — EWS3 disables used key positions, and we can free them so a used key or a fresh transponder can be written in.
Do you cover Mini R50 and Range Rover L322?
Yes — both use BMW EWS3-family immobilisers and are covered by this service.
