The POCO X7 Pro doesn’t support the car keys feature.
For your reference, the reasons are as follows:
1. Digital car keys require compatibility with specific manufacturers' protocols, such as NFC or UWB (Ultra-Wideband) standards. Since not all carmakers use standardized systems, implementing universal car key functionality can be challenging;
2. Supporting digital car keys requires advanced hardware, such as dedicated UWB technology or enhanced NFC modules. Although the POCO X7 Pro offers NFC, it lacks the specific hardware required for car key functionality;
3. The car key feature is a niche requirement, mainly utilized in premium smartphone models and regions where smart cars are common. POCO X7 Pro focuses on other widely demanded features, making this functionality less of a priority.
