About this document

Mid City Engineering designs and manufactures automotive electronics in Chicago, including:

  • Remote starters — the SmartKey Starter and SKS-NG series, for push-to-start and key-start Mercedes (Sprinter, C-Class, E-Class, GLE, S-Class, etc.), Porsche, Volvo, and Audi vehicles.
  • High-idle / SmartIdle interfaces — raise engine RPM while parked to charge batteries and run accessories, primarily for Mercedes Sprinter vans and RVs.
  • Radar-detector interfaces — integrate Escort (Redline CI, Max CI, 360 CI) and similar radar/laser detectors into the factory instrument cluster and steering-wheel controls.
  • OBD programmers — plug-in devices that configure vehicle features such as crosswind-assist delete, tire-size/speedometer calibration, fuel-gauge / Miles-to-Empty (J-51 / 907 MTE), camera programming, and eco/auto-start-stop disabling.
  • Alarm integration kits and camera systems.

This reference documents the common support issues for these products and their verified resolutions — including diagnostic procedures (parking-light flash codes, LED indicators), installation and wiring guidance, configuration steps, and escalation paths.
