OEM vs Aftermarket Keyless Ignition: Pros, Cons & Myths
The convenience of a push-button start system is one of the most sought-after features in modern vehicles. No more fumbling for keys—just get in, press a button, and go. While many new cars roll off the assembly line with this technology, what about the millions of other vehicles on the road? This is where the debate between OEM and aftermarket keyless ignition systems begins.
If you own a classic car, a custom hot rod, or a vehicle that didn't come with a factory-installed system, an aftermarket solution can be a game-changing upgrade. This guide will compare OEM (Original Equipment Manufacturer) and aftermarket keyless ignition systems, breaking down the pros, cons, and common myths associated with each. You'll discover why an aftermarket system often provides superior security, customization, and compatibility for a wider range of vehicles.
What's the Difference Between OEM and Aftermarket?
OEM (Original Equipment Manufacturer): These are the keyless ignition systems designed and installed by the car manufacturer (like Ford, Toyota, or BMW) during the vehicle's assembly. They are engineered specifically for that make and model.
Aftermarket: These systems are produced by independent companies, like Digital Guard Dawg, that specialize in automotive electronics. They are designed to be installed in a vehicle after it has left the factory, offering compatibility with a vast range of cars, trucks, and motorcycles, including those built long before keyless technology was common.
OEM Keyless Ignition Systems: The Pros and Cons
Pros of OEM Systems
- Seamless Integration: Since the system is designed by the manufacturer, it integrates perfectly with the vehicle's electronics and interior design.
- Warranty Coverage: A new vehicle's bumper-to-bumper warranty typically covers the keyless ignition system.
- No Installation Required: The system is ready to go the moment you drive the car off the lot.
Cons of OEM Systems
- Limited Availability: OEM keyless start is generally only available on newer, often higher-end, trim levels.
- Lack of Customization: OEM systems are one-size-fits-all. You can't choose the style of your start button or add custom features.
- Expensive Repairs and Replacements: Losing an OEM key fob can be costly. Replacement and reprogramming must be done at a dealership and can run several hundred dollars.
- Potentially Weaker Security: While modern OEM systems are secure, older factory systems may use less sophisticated encryption, making them more vulnerable to advanced theft techniques like relay attacks.
Aftermarket Keyless Ignition Systems: The Better Choice for Many
Pros of Aftermarket Systems
- Universal Compatibility: Can be installed in almost any vehicle, regardless of its age or make. Whether you have a 1969 Camaro or a 2010 work truck, you can add modern keyless convenience.
- Enhanced Security: Leading aftermarket companies use more advanced RFID encryption and rolling code technology than older OEM systems. Digital Guard Dawg's proprietary DFDE (Dual Frequency ~ Dual Encryption) technology provides exceptional protection against code-grabbing thieves.
- Full Customization: Choose from dozens of start button styles, from classic billet aluminum to genuine OEM buttons from brands like Honda or even Aston Martin.
- Advanced Features: Systems like the PBS-II allow you to control power accessories like door locks, windows, and trunk release from the key fob. The iKey Premier adds true Passive Keyless Entry (PKE).
Cons of Aftermarket Systems
- Installation Required: Needs to be installed. Professional installation is often recommended.
- Potential for Poor Quality (If Not Chosen Carefully): The market is flooded with cheap, low-quality systems. Choose a reputable brand with a proven track record.
Debunking Common Myths
Myth 1: Aftermarket systems are less secure than OEM.
Fact: This is often the opposite of the truth. Reputable aftermarket systems from specialists like Digital Guard Dawg are built with security as the top priority.
Myth 2: Installing an aftermarket system will void my car's warranty.
Fact: In the United States, the Magnuson-Moss Warranty Act protects consumers. A manufacturer cannot void your entire vehicle warranty simply because you installed an aftermarket part.
Myth 3: Aftermarket systems look cheap and out of place.
Fact: High-quality systems are designed to look sleek and factory-installed. With a massive selection of OEM-style and custom start buttons, you can achieve an integrated look.
The Verdict: When is Aftermarket the Right Choice?
- Choose OEM if: You are buying a brand-new car and the feature is included in a trim level you already want.
- Choose Aftermarket if: You own a classic, custom, or older vehicle; you want superior security features; you want to customize the look and feel of your ignition system.
For most drivers looking to upgrade, an aftermarket system offers a level of freedom, security, and personalization that OEM systems simply can't provide.
