I-CAR · July 8, 2025 · General Motors
Summary
This article outlines General Motors' digital key and key card systems, which rely on UHF transceivers located in collision-prone areas like bumpers and entry points. It establishes that a Digital Key Sensor Position Learn procedure is mandatory whenever any digital key system component is replaced.
What to do on the job
Perform the Digital Key Sensor Position Learn procedure whenever any digital key system component (such as bumper-mounted transceivers) is replaced, ensuring stable battery voltage and device preparation beforehand.
How to use it
When writing an estimate or supplement for bumper or door replacements on GM vehicles equipped with digital keys, include line items for the Digital Key Sensor Position Learn procedure and battery support. Use this document to justify the calibration labor by showing that GM explicitly requires this learn procedure whenever digital key components are replaced.
