Can you add remote start to a car that doesnt have it?

Yes. In most cases you can add remote start to a car that didn’t come with it, either through aftermarket kits or an available OEM option, depending on the model, year, and transmission. The right path depends on your vehicle, budget, and safety considerations.

Understanding feasibility

Several variables determine whether you can add remote start and how smoothly it will work. Here are the key factors to consider:

• Transmission type: Automatic transmissions are typically compatible with most remote-start kits. Manual transmissions are usually not supported by standard aftermarket systems due to safety concerns, and some jurisdictions restrict remote starting a manual car.


• Immobilizer and security: Cars with built‑in immobilizers often need a bypass module or an OEM-style integration to start remotely without the key, which adds complexity.


• Electrical architecture: Modern CAN-bus systems may require specialized adapters to communicate with existing modules without causing faults or warnings.


• Warranty and insurance: Aftermarket installations can affect warranties and insurance coverage; check with the dealer and your insurer before proceeding.


• Safety and reliability: Hood, door, brake, and gear-position safety features are commonly wired into remote-start systems to prevent unintended starts or movement.

If you’re unsure about your specific model, a professional assessment is the best way to determine feasibility and avoid unintended consequences.

Options to add remote start

There are two general routes to adding remote start: aftermarket kits and OEM/official options. Each has distinct advantages and trade-offs.

Aftermarket remote start kits

Aftermarket kits are widely available and can work with many older and newer cars. They typically include a control module, one or more remotes (or a smartphone app), a immobilizer bypass (when needed), and wiring harnesses. Installation quality and compatibility vary by vehicle and installer.

• Pros: Broad compatibility, often lower upfront cost, wide selection of features.


• Cons: Installation quality matters; some cars require advanced CAN-bus integration; potential warranty concerns.

Bottom line: Aftermarket kits offer flexibility and cost advantages, but require careful model matching and reputable installation to ensure reliability and security.

OEM remote start options

Some carmakers offer remote start as an official option or as part of a connected-services package. These solutions tend to integrate more seamlessly with the vehicle’s security and electronics and may preserve warranty coverage when installed through a dealer.

• What you get: Factory-style integration, often with the same push-button/remote experience as other features and support from the brand network.


• Pros: Strong compatibility, potential warranty and service benefits, better deep-system integration.


• Cons: Availability varies by model/trim; higher upfront cost; may require newer vehicles.

Bottom line: OEM options offer smoother integration and better dealer support but may be limited to specific models or trims and can be pricier.

Smartphone/app-based solutions

Some solutions use connected-services or aftermarket modules that let you start or schedule a start via a smartphone app. These depend on your car’s compatibility and may require a subscription.

• What you get: Start via app, often with additional features like climate preconditioning and remote confirmations.


• Pros: Convenience and remote control from anywhere; may be bundled with other connected services.


• Cons: Service availability and costs vary; privacy and data considerations; may require ongoing subscriptions.

Bottom line: App-based options can be very convenient, but verify service coverage, costs, and data privacy before committing.

Installation considerations

Before you commit to a particular path, weigh these installation realities and planning steps:

• Professional installation is strongly recommended to ensure correct wiring, immobilizer handling, and safety interlocks.


• Request a written warranty for both hardware and labor from the installer.


• Ensure compatibility with your vehicle’s security system and verify that the setup won’t trigger fault codes or warning lights.

• Ongoing costs: Potential subscription fees for app-based or connected services.

Conclusion: Plan for parts plus professional installation, and factor in potential ongoing service costs if you choose app-based or OEM-connected options.

What to ask before you buy

To avoid surprises, ask installers or retailers these questions:

• Is the kit compatible with your exact year, make, model, and engine?


• Does it support your preferred starting method (remote, app, or both) and what is the range?


• Will immobilizer bypass be required, and does it preserve anti-theft protections?


• What is the warranty on parts and labor, and who covers what if something fails?


• Could installation affect your vehicle’s warranty or insurance, and are there recommended service providers?

Conclusion: Clear, written answers help you compare options and avoid costly missteps.

Summary

For many cars, adding remote start after purchase is feasible through aftermarket kits, OEM options, or app-based solutions. The right choice depends on your vehicle’s transmission, security system, and electrical architecture, as well as your budget and tolerance for risk. A qualified installer or dealer can guide you to the safest, most reliable option, ensuring proper integration with safety features and preserving warranty where possible. If you decide against modifying, some newer models offer factory remote-start or connected services as part of higher trims or packages.

Can remote start be added to any vehicle?

No, remote start cannot be added to every vehicle, but most vehicles with automatic transmissions, especially those made after the mid-2000s, can have an aftermarket system installed. The most significant hurdles are the vehicle's security system and the transmission type, so it is crucial to confirm compatibility with a professional before purchase and installation, Autozone and CarParts.com report. 
Factors that affect compatibility

• Transmission type: Remote start is possible on manual transmission vehicles, but it is not recommended due to the lack of a starter lockout feature, which could allow the car to start while in gear. 
• Vehicle age: Most modern cars, especially those made after the mid-2000s, are good candidates for remote start. Older vehicles may require more complex or custom installations. 
• Security system: The vehicle's anti-theft and immobilizer systems are the main technical challenges for adding remote start. A bypass module is often required to get around these systems. 

Options for installation
