Question
What is the difference between “OEM” and “aftermarket” TPMS sensor firmware?
Answer
OEM firmware is locked to one brand; aftermarket (CHEPQ) supports multiple makes via updates.
Explain
OEM sensors can’t be reprogrammed for other vehicles; CHEPQ sensors update firmware to add new protocols (e.g., 2024 Hyundai TPMS).
