Mercedes-Benz Mail-In Module Programming
EIS cloning, key replacement, and ELV emulator — pre-2014 specialty
Mercedes ELV Emulator — $350 vs $2,400 dealer
The OEM Electronic Steering Lock is the #1 most-reported Mercedes electrical fault on W204/W212/W166/X204/Sprinter. Dealer replaces the failure-prone motor for $1,800-$3,500. AML's ELV Emulator bypasses the motor entirely with solid-state electronics — permanent fix, $350 flat, no recurrence.

Mercedes W164/X164/W251 EIS Repair
ML/GL/R key won't turn, or the EIS is dead? We repair (not clone) the original EIS on Mercedes 2008-2012 DAS3 infrared systems — your keys keep working.
Mercedes ESL Motor Repair & Clone
We rebuild the failed motor inside your OEM Electronic Steering Lock or clone it to a donor — keeping the genuine part, not swapping in an emulator.
Mercedes ME9.7 / MED17 ECU Clone
Used Mercedes engine ECU that cranks but never starts? We clone it to your car's exact data — VIN, FBS3 immobilizer, and adaptations — so the replacement runs plug-and-play.
Mercedes SIM271DE2.0 ECU Clone / Renew
Replacing a failed Continental SIM271DE2.0 engine ECU on a 2010-era Mercedes? Mail in your original plus a used donor and we clone the identity, immobilizer, and drive-authorization data across on the bench — plug and play. Renew-to-virgin available when a clone isn't possible.

Failed 722.9 conductor plate? Mail in your original (and a donor) and we clone your data over, or virginize a donor and SCN-code it to your VIN — plug-and-play.
Mercedes 722.9 NEW Conductor Plate — NASTF-Ordered, Programmed
No original to clone? We order a BRAND-NEW 722.9 plate from Mercedes for your VIN through NASTF, program and SCN-code it, and ship it plug-and-play.
Mercedes FBS4 DSM / ISM Cloning (2013+)
Newer Mercedes DSM/ISM shifter or servo module failed? On FBS4 cloning is the only fix — mail in your original plus a donor and we clone it plug-and-play.
Mercedes ME9.7 ECU — SCN / Unlock / VIN-Write / Clone
Dead ME9.7, or a used one the car refuses? Everything the engine computer needs on the bench — unlock, VIN write, SCN code, or clone your data onto a replacement.
Mercedes SCN Coding — EIS / ECU / Cluster / TCU
Bought a used or new Mercedes module elsewhere and it needs SCN coding to work? Mail it in and we online-SCN-code it to your VIN.
Sprinter Remote Key & All-Keys-Lost
Lost every key to your Sprinter? Ship the EIS and your door lock and we cut and program a working remote key — no tow, no dealer appointment, van back on the road.
Sprinter "Start Error" Repair (T1N)
The classic T1N Sprinter START ERROR on the dash — we resynchronize the key, immobilizer and ECM on the bench and clear the counters, returned plug-and-play.
Sprinter Valet Key (Start-Only)
The budget path back to a running Sprinter: a start-only key programmed to your EIS, blade cut from your door lock. $250 flat, all keys lost included.
Mercedes AAM / DAS Valet Key (ML, SLK, SL & More)
A working start-only key for the Mercedes the dealer gave up on — ML320/ML430, SLK, SL, W140 S-Class, G-Wagen and more. Ship the AAM or DAS immobilizer box and we program the key to it.
Mercedes AAM / DAS Repair (ML No-Start)
ML320 cranks but will not start? Key suddenly not recognized? The AAM immobilizer is the usual suspect — ship it and we repair and resynchronize it on the bench.
Mercedes Classic Remote Key (SLK, SL, W140, G)
A full remote key — start, lock and unlock — for late-90s Mercedes the dealer no longer supports. Programmed from your DAS/SKREEM or AAM module on the bench.
