Mercedes-Benz EIS Key Programming & Cloning - 2 Keys - 24HR Turnaround

Mercedes-Benz EIS Diagnostic, Key Programming & Cloning Service

WMSTek LLC – Nationwide Mail-In Service

Two Replacement Keys Included at No Additional Charge

WMSTek LLC provides professional Mercedes-Benz EIS diagnostic, key programming, pairing, data-retrieval, and cloning services for supported FBS3/DAS3 vehicles.

For most customers, the process is straightforward: send us your EIS, we retrieve the required data, program and verify your replacement keys, and return everything ready to reinstall.

In most cases, your EIS is functioning normally and the service only requires standard data retrieval, key programming, pairing, and final testing.

The additional diagnostic, cloning, repair, and board-level procedures described below are only required in less common situations where an EIS has an internal fault, corrupted or damaged data, previous repair/programming issues, or a design that requires more involved access.

Most customers will not require these additional procedures.

If we discover that your EIS requires work beyond normal key programming, we will contact you before performing any additional paid service.

This listing is primarily for the professional service and labor performed on your EIS. The replacement key fobs supplied with the service are included at no additional charge.

WHAT\'S INCLUDED

✅ Professional bench-level EIS diagnostic and functionality testing

✅ EIS communication and data verification

✅ EIS password/data retrieval when required

✅ Key programming and pairing

✅ Two (2) new Mercedes-Benz Generation 4-style replacement key fobs included at no additional charge

✅ Verification of key/EIS communication

✅ EIS data transfer or cloning when technically required, supported, and applicable. Cloning is an additional fee which is rare in most cases.

✅ Final bench testing before return

Not every EIS requires every procedure listed above. The exact work performed depends on the EIS type and condition of the module received.

Bench testing is limited to the components and functions that can be tested outside the vehicle and cannot reproduce or rule out every possible vehicle-side electrical, communication, or immobilizer fault.

MULTIPLE-KEY DISCOUNT

Discounted service pricing is provided when programming more than one key during the same service.

Because the primary EIS diagnostic, data retrieval, password calculation, and programming setup only needs to be completed once, the programming service for additional keys can typically be provided at a reduced rate.

The physical replacement key fobs themselves are included with the service at no additional charge.

SERVICE PROCESS

• Disconnect the vehicle battery.

• Carefully remove the EIS/EZS module where the key is inserted.

• Ship the EIS and any existing working keys, if available, to our facility.

• We perform bench-level diagnostic testing, retrieve the required data, program/pair the replacement keys, and perform final bench verification.

• Your EIS, original keys, and newly programmed replacement keys will be returned to you after the service is completed within 24 hours after recieved in most cases.

Shipping instructions and our shipping address will be provided after purchase.

PROCESSING TIME

Most standard EIS/key-programming services are completed within 1 business day after your package is received.

Processing times are estimates and are not guaranteed.

Orders requiring additional diagnostics, board-level work, repair, cloning, replacement modules, or other specialized procedures may require additional processing time.

If standard service is completed before 10:00 PM Pacific Time, we make every effort to ship the completed order within 24 hours.

Expedited return shipping may be available for an additional charge.

IMPORTANT – FUNCTIONAL EIS REQUIREMENT

Standard key programming requires an EIS that is functional and capable of accepting additional keys.

A vehicle that previously started or operated normally does not necessarily guarantee that the EIS is capable of accepting additional keys.

During the programming process, we may discover an internal EIS issue such as:

• Corrupted or damaged EIS data

• Internal memory/EEPROM faults

• Communication problems

• Failed or inconsistent key-track data

• An EIS that will no longer accept or pair additional keys

• Previous unsuccessful programming or repair attempts

• Internal electrical or hardware faults

If an EIS fault prevents normal key programming, we will contact you with the available repair, cloning, or replacement options.

No additional paid repair, replacement, cloning, or board-level work will be performed without customer approval.

EIS CLONING / REPLACEMENT

If your original EIS cannot reliably accept new keys, transferring or cloning its data to a compatible replacement EIS may be recommended.

Where technically supported and applicable, EIS cloning/data-transfer labor may be performed as part of our service process.

Replacement or donor EIS hardware is not included in the standard service price unless specifically stated.

The customer may provide a compatible replacement EIS, or WMSTek LLC may be able to assist with obtaining one for an additional charge.

Customer-supplied replacement modules should be approved by WMSTek LLC before purchase whenever possible.

We cannot guarantee compatibility of an unverified customer-supplied replacement EIS.

W215 & W220 – ADDITIONAL $200 BOARD-LEVEL SERVICE FEE

Mercedes-Benz W215 and W220 EIS modules require an additional $200 service fee due to the substantially greater labor involved in retrieving the programming data.

Unlike many later EIS modules, these units may require specialized board-level procedures including:

• EIS disassembly

• Direct circuit-board access

• Precision soldering

• Electrical connections to board-level components or test points

• EEPROM/MCU data extraction

• Data verification

• Additional bench testing

• Reassembly after programming

This work requires substantially more time and intricate electrical work than our standard EIS programming procedure.

The additional $200 W215/W220 board-level service charge is separate from the standard listing price.

IMPORTANT DIAGNOSTIC FEE DISCLOSURE

Once your EIS has been received and bench diagnostic/programming work has begun, a minimum $100 diagnostic/service charge applies.

This charge compensates WMSTek LLC for labor already performed, which may include:

• Module communication

• EIS data retrieval

• Password/data calculation

• Key-track verification

• Bench testing

• Programming attempts

• Identification of EIS-related faults

This diagnostic/service charge applies even if an internal EIS fault prevents successful key programming or if the customer declines additional recommended repair, cloning, or replacement work.

The diagnostic/service portion of the order is non-refundable once testing has begun.

If additional repair or replacement work is recommended, the customer may:

• Approve the recommended additional service; or

• Decline additional work and have the original items returned.

If additional work is declined, any eligible refund will be reduced by the diagnostic/service labor already completed.

VEHICLE-SIDE PROBLEMS

Our mail-in service is limited to the EIS/key components and the work that can be performed and tested at our facility.

Successful EIS/key programming or bench testing does not guarantee that an unrelated vehicle no-start or immobilizer problem will be corrected.

Vehicle-side problems may involve components including:

• ESL / electronic steering lock

• SAM modules

• ECU / ME

• ISM or transmission authorization modules

• CAN communication

• Vehicle wiring

• Power or ground circuits

• Fuses or relays

• Vehicle battery

• Other immobilizer or electrical components

Diagnosis or repair of these vehicle-side components is not included with this mail-in service.

CUSTOMER-SUPPLIED OR PREVIOUSLY SERVICED MODULES

WMSTek LLC is not responsible for problems caused by:

• Incorrect replacement part numbers

• Incompatible donor modules

• Previous programming attempts

• Previous repair attempts

• Water or physical damage

• Previously opened or modified EIS modules

• Damaged circuit boards

• Corrupted data caused before the module arrived at our facility

Modules requiring additional repair because of previous damage, modification, or programming attempts may require additional charges or may be returned without further service.

LIFETIME WARRANTY ON KEYS

All replacement keys supplied by WMSTek LLC include a Lifetime Key Warranty for as long as the original customer owns the vehicle.

The warranty covers failures or defects of the replacement key under normal use.

The warranty does not cover:

Please contact us before sending a key in for warranty service.

FUTURE REPLACEMENT KEYS

WMSTek LLC securely retains customer EIS programming data on file for future service.

If you need another key for the same vehicle in the future, you will normally not need to remove and ship your EIS to us again, provided the vehicle\'s original EIS/security system has not been replaced or altered.

Additional keys are currently available for $99 each with return shipping included.

Future pricing and key availability are subject to change.

SHIPPING & HANDLING

Buyer is responsible for safely packaging and shipping the EIS and any original keys to our facility.

Return shipping is included with standard service.

USPS, UPS, or FedEx may be used for return shipping.

Overnight or expedited shipping may be available at the customer\'s expense.

WMSTek LLC is not responsible for packages that are lost, delayed, or damaged while being shipped to our facility.

VEHICLE COMPATIBILITY

This service is designed primarily for Mercedes-Benz vehicles equipped with the FBS3 / DAS3 immobilizer system.

FBS4 vehicles are not supported by this standard key-programming service.

We can service a large range of Mercedes-Benz vehicles, with most supported applications being 2014 model year and older.

However, model year alone does not determine whether a vehicle uses FBS3 or FBS4. Some vehicles produced before 2015 may use a different immobilizer generation.
