Can I upgrade my car to keyless entry?
Yes. In most cases you can add keyless entry to a car either with an aftermarket kit or through an OEM-style upgrade, but what fits depends on your model, age, and budget. This article explains the options, what to expect, and how to approach the upgrade safely.
What keyless entry means for your car
Keyless entry refers to the ability to lock and unlock a vehicle without inserting a physical key. Basic systems use remote fobs to operate door locks, while newer setups may include passive entry (automatic unlock when you approach) and push-button start. Upgrading your car to keyless entry can range from a simple remote control upgrade to a full factory-style system with proximity sensing and start capability.
Paths to upgrading your car
Here are the main routes you can take, depending on your vehicle and your goals:
- Aftermarket remote keyless entry (RKE) kits: These add remote lock/unlock, sometimes trunk release and a basic alarm. They require installation of door actuators and a control module; many kits are DIY-friendly but professional installation is recommended for reliability and security.
- OEM-style upgrade through a dealer or certified installer: For vehicles that support modular upgrades, you can add factory-like keyless entry or even passive entry and start. This tends to be more seamless but costs more and may require compatible hardware and reprogramming.
- Smartphone-enabled or telematics-based options via existing services: If your car already supports manufacturer services (for example OnStar, Blue Link, or similar), you may unlock remote features through the app, sometimes with a subscription; retrofitting these features into older cars is typically limited to supported hardware and service plans.
- Manual locks? You’ll also need power door lock hardware: If your car has traditional manual locks, enabling keyless entry will require converting to power locks and connecting actuators, which adds cost and complexity.
Not all vehicles are equally receptive to upgrades; some models—especially older ones or those with advanced security systems—may require specialized modules or may not be compatible with certain aftermarket kits. Always verify compatibility and security implications with the installer or dealership.
What to know before you commit
These considerations will help you decide the best path and avoid surprises after installation:
- Assess your goals: Do you want remote lock/unlock only, trunk release, remote start, or passive entry?
- Check compatibility: Identify whether your car has power door locks, what year and trim you have, and whether the vehicle’s immobilizer system can be integrated with aftermarket hardware.
- Choose between aftermarket vs OEM: Aftermarket kits are cheaper and flexible but may void warranties or impact security; OEM upgrades are more seamless but costlier and model-dependent.
- Plan for keys and programming: You’ll likely need new or reprogrammed key fobs and possibly dealer or professional programming to ensure reliability.
- Consider installation and warranty: Professional installation is advised for security and reliability; confirm any warranty implications and whether the installer offers a warranty on labor and parts.
- Factor in safety and security: Remote start and other features can pose safety risks (e.g., starting a car in a garage); ensure features are configured with safe usage in mind.
After weighing these steps, you can determine whether an aftermarket kit, an OEM upgrade, or a manufacturer-enabled telematics option best fits your vehicle and needs.
Security, warranties, and costs
Security and reliability
Security is a key concern with any upgrade. Aftermarket systems can introduce vulnerabilities if not properly installed or updated. Work with a reputable installer who follows best practices, uses high-quality modules, and ensures proper immobilizer integration. Avoid shortcuts that bypass anti-theft features, and keep all software up to date.
Costs and warranties
Costs vary widely. Basic aftermarket RKE installations can start around a few tens of dollars for components if you DIY, but professional installation usually ranges from roughly 150 to 500 or more, depending on features and vehicle complexity. OEM-style upgrades and dealer-installed options can run higher, often several hundred to over a thousand dollars, plus potential subscription fees for telematics services. Check warranty implications with the installer or your dealer before proceeding.
Summary
Most cars can be upgraded to keyless entry, but the best path depends on your vehicle’s age, hardware, and your priorities. Aftermarket kits offer affordability and flexibility but may require more hands-on setup and careful compatibility checks. OEM upgrades provide seamless integration and stronger support but at higher cost and with model-specific limitations. Always verify compatibility, consider security and warranty impacts, and rely on a qualified installer to ensure a reliable, safe upgrade.
