If your BMW’s EWS3 immobilizer module has failed, is causing no-start issues, or won’t recognize keys, our professional cloning and programming service provides an affordable, plug-and-play solution.

We extract all critical data from your original EWS3 module — including VIN, ISN, and synchronization codes — and transfer it to a donor EWS3 module. Your replacement will work seamlessly with your DME/ECU and existing keys, avoiding expensive dealer replacements.

How Our Service Works

1. Send your original EWS3 module and a compatible donor module to our facility.

2. We clone all immobilizer and synchronization data to the donor module.

3. Your cloned module is bench-tested and returned ready for plug-and-play installation.

Why Choose Our Service?

• Fast Turnaround: Same-day processing if parts arrive before noon (Mon–Fri). Typical total time: 3–5 days including shipping.

• Plug & Play: Donor module syncs directly with your ECU/DME and keys — no additional coding required.

• Expert Handling: Data securely read from your original EWS3, written to the donor, and thoroughly tested.

• Cost-Effective & Eco-Friendly: Reuse existing modules and save hundreds compared to OEM replacements.

Important Notes

• Confirm module part number, VIN, or photos before sending to ensure compatibility.

• Only for EWS3-equipped models. CAS-based systems require different services.
