The manufacturer hard-codes restrictions into the device firmware, preventing it from transmitting on forbidden or restricted frequencies (like those reserved for emergency services or aviation). How to Defend Against Brute Force Attacks

The Flipper Zero can read, emulate, and save Low-Frequency (125 kHz) RFID and High-Frequency (13.56 MHz) NFC cards. 🏷️ 125 kHz RFID (Emarine & HID)

The Flipper Zero is an extraordinary device—a Swiss Army knife for wireless experimentation. Its brute-force capabilities are real, powerful, and dangerous, but only against obsolete or cheaply designed static-code systems. A full brute force that works on modern rolling-code locks, cars, or garage doors does not exist on the Flipper Zero, nor will it anytime soon.

Replace old 433MHz garage openers with rolling-code systems.
