> Secure Passive Entry for your Tesla via BLE.

TeslaKee is a secure alternative to the official Tesla PhoneKey application for Android devices. It was designed specifically to mitigate BLE (Bluetooth Low Energy) relay attacks and provide advanced access control.

## Key Features

1. **Hardware-Backed Security (StrongBox)**
   Unlike the official application, TeslaKee generates and stores your cryptographic vehicle keys inside the Android StrongBox Keystore. This ensures keys cannot be extracted even if the device operating system is compromised.

2. **Relay Attack Mitigation**
   The official Tesla application continuously broadcasts your key. TeslaKee intelligently stops broadcasting if:
   - You are not physically near your vehicle.
   - Your phone has not detected motion for more than 5 minutes (e.g., keys resting on a kitchen counter).

3. **Advanced Policy Engine**
   Users can configure specific rules for when the key is active:
   - **Time Windows**: Restrict access to daytime hours.
   - **Geofencing**: Prevent unlocking when parked at specific locations like home or work.
   - **Trusted Networks**: Disable the key while connected to the home WiFi.

4. **Multi-Vehicle Support**
   The application is free for single-vehicle usage. Users with multiple Tesla vehicles can upgrade to the Premium tier (€2.49/mo) to manage unlimited vehicles with per-vehicle security policies.
