The digital car key market is experiencing a significant boom, with a growing number of aftermarket options available. As you consider upgrading your vehicle with a digital key, a crucial question arises: What is the best technology to power it? The primary technologies used for digital car keys are Bluetooth and GSM. While both offer remote access, their differences in security, cost, and reliability are key. MoboKey, for instance, has chosen an encrypted Bluetooth-based system that avoids the hidden costs and vulnerabilities of other technologies.

The Case for GSM: Long-Range, But at What Cost?

GSM (Global System for Mobile Communications) technology offers an almost unlimited range for car access. A GSM-based system relies on a SIM card inside the vehicle to communicate with your phone via SMS or a data connection. This means you can send commands to your car from anywhere with a cellular connection, which is a major advantage for fleet managers.

However, GSM comes with significant drawbacks:

  • Hidden Costs: The presence of a GSM module in a vehicle’s security system automatically increases its cost. Furthermore, a SIM card requires a monthly or annual subscription fee, which adds to the long-term cost of ownership.
  • Security Vulnerabilities: While GSM provides some security features, its encryption is considered weak compared to newer standards. It is susceptible to various extraneous signals and can have security flaws.
  • Network Dependency: GSM systems rely heavily on a stable cellular network connection. In areas with weak or no signal, the system’s functionality may be limited.

The MoboKey Advantage: The Power of Bluetooth

MoboKey has chosen a Bluetooth-based system that offers a more secure, reliable, and cost-effective solution. Here is how it stands out:

  • Superior Security: MoboKey uses AES-encrypted communication over Bluetooth, which makes it extremely difficult for anyone to intercept or manipulate the signal. This technology is considered much safer than the RFID technology used in smart key fobs. It also avoids the security risks and network vulnerabilities of GSM and GPS-based solutions.
  • Low Cost and No Subscriptions: Since MoboKey does not require a SIM card, there are no monthly or annual subscription fees. The entire system operates on a one-time device cost, making it a more affordable long-term investment.
  • Offline Functionality: Because it uses Bluetooth, MoboKey can function even in areas with no cellular signal, such as underground parking garages. It relies on your smartphone’s Bluetooth connection, which is more reliable for short-range communication.

A Clear Winner for Smart Vehicle Access

When it comes to choosing a digital car key technology, the choice between Bluetooth and GSM is clear. While GSM offers long-range control, its costs, security flaws, and reliance on cellular networks make it a less ideal choice for a modern digital car key. MoboKey’s Bluetooth-based solution offers a superior combination of security, cost-effectiveness, and reliability. It provides a comprehensive solution that gives you peace of mind without the burden of ongoing subscriptions.
