Owning an older vehicle doesn’t mean you have to miss out on the latest comforts and security features. In fact, adding keyless entry and remote start can be one of the most rewarding upgrades you can make. The aftermarket industry, led by innovators like MoboKey, has made it simple and affordable to retrofit a traditional turn-key vehicle with smartphone-controlled technology.

Here is your guide to upgrading your old vehicle to a smart, keyless car.

1. The Feasibility: Converting a Turn-Key Ignition

For years, it was assumed that only new cars could have remote access. However, aftermarket systems are designed to integrate with your existing electrical system, converting the functions of your keyed ignition into digital commands.

  • Turn-Key Conversion is Possible: Systems like MoboKey can be installed on vehicles with a traditional key ignition, transforming the manual turn-and-hold process into a smartphone-activated command.
  • The Immobilizer Challenge: Most cars manufactured after 1998 include an engine immobilizer—a security feature that prevents the engine from starting without a correctly coded chip present in the key. For a remote start system to work, it must use a bypass module to temporarily trick the car into thinking the key is present.

2. Essential Components for the Upgrade

To achieve full smartphone-controlled access and remote start functionality, you need four key components:

Component Purpose MoboKey Solution
Control Module The “brain” that sends signals to the car’s lock and ignition wires. MoboKey Device (Pro Model)
Bypass Module Deactivates the factory immobilizer during remote start. External Unit (Needed for remote start)
Wiring & Integration Connects the control module to the ignition, starter, and lock wires. Specific Wiring Harness (Simplifies connection to ACC, Ignition, Start)
App-Based Remote Replaces the physical key or fob for control. MoboKey App (Free, no subscription)

3. Installation, Cost, and Professional Advice

Attempting complex automotive wiring can create electrical problems or void your warranty. The best approach is to seek professional installation.

  • Cost of Kits and Installation: The overall cost depends on your vehicle and the kit you choose. A basic remote start system typically costs between $150 and $500 for the kit alone. Professional installation can add another $100 to $600 to the price, depending on the complexity of your vehicle’s wiring and immobilizer.
  • Recommendation: Professional Installation: Due to the risk of issues and the complexity of integrating with security and ignition wires, hiring an experienced car electrician or auto security professional is highly recommended.

Why MoboKey is the Best Choice for Retrofitting

MoboKey stands out as the ideal aftermarket solution for older vehicles:

  • Universal Compatibility: MoboKey works with a vast majority of key-start and push-start vehicles, making it a reliable solution regardless of your car’s age or model.
  • Smart Features: You gain more than just remote start; you get hands-free proximity lock/unlock, digital key sharing, and the Engine Kill anti-theft feature.
  • One-Time Fee Model: MoboKey avoids the costly monthly subscription fees charged by many competitors (like DroneMobile or Viper SmartStart) for app-based control, making it a superior long-term investment.
