Cero Llave

CeroLlave is an innovative app for Wear OS smartwatches that transforms your watch into a smart digital key. It unlocks and locks your vehicle using Bluetooth Low Energy (BLE) technology, without having to touch your phone or use a physical key.

Main Features
• Manual control from your smartwatch: Lock or unlock your vehicle by tapping an icon on the screen.
• Automatic proximity mode: When you approach the vehicle, it unlocks automatically. If you move away, it locks.
• Simple and fast interface: Large, intuitive buttons with no text. Only icons for greater visual comfort.
• Easy setup: Enable or disable automatic proximity detection from the settings section.

Privacy and Security
CeroLlave does not store personal data or require an internet connection. The connection is made directly between your watch and the vehicle via secure Bluetooth.

Requirements
• Smartwatch with Wear OS.
• Vehicle with BLE receiver module.

CeroLlave is ideal for drivers who want more convenient, secure, and modern access to their vehicle, without complications or physical keys.
