For decades, the key fob has been the standard for remote car access. This small device gave us the power to lock and unlock our cars with the press of a button. However, technology is moving on. Today, your smartphone is poised to replace the key fob entirely, offering a level of convenience, functionality, and security that a traditional fob simply cannot match. MoboKey’s solution transforms your smartphone into the ultimate vehicle remote, providing an all-in-one digital key that simplifies every aspect of car ownership.

The Problem with a Traditional Key Fob

A key fob is fundamentally limited by its hardware. It is a bulky, single-purpose item that comes with major flaws:

  • Limited Range: Key fobs work only within a limited, short range—often only a few hundred feet. You cannot start your car from your office, a restaurant, or a different floor in your building.
  • Security Vulnerabilities: Many key fobs are vulnerable to a type of car theft known as a relay attack. Thieves use signal amplifiers to trick the car into unlocking and starting, a risk that is eliminated with an encrypted digital key.
  • Single-User Access: Fobs are cumbersome to share. Lending your car requires physically handing over the device, which creates security risks and major inconvenience.

How a Smartphone Becomes the Ultimate Remote

Your smartphone is already the central hub for your life, making it the perfect tool to control your vehicle. MoboKey’s technology turns your device into a comprehensive car remote, providing superior convenience and functionality.

A smartphone-based remote is also a superior security and management tool:

  • Enhanced Security: MoboKey uses AES-encrypted Bluetooth communication, making it highly resistant to the types of hacks that threaten key fobs.
  • Instant Access Revocation: If your phone is lost, you can log in from any other device and instantly revoke access to your digital car key, a crucial security feature that a key fob cannot offer.
  • Centralized Control: You can manage the access, security, and remote features of multiple vehicles from a single MoboKey app dashboard, which is perfect for fleet managers and car-sharing hosts.
