Remote keyless fobs operate on RF frequencies (typically 315 MHz or 433 MHz), sending encrypted commands to the vehicle's main getting unit. Smart keys utilize a combination of low‑frequency (LF) for proximity detection and RF for safe communication. This dual‑layer approach enhances security while offering convenience.
