Can you add a remote start to a car that doesnt have it?
Yes—it's usually possible to add remote start to many cars that didn’t come with one, but it typically requires either a factory-installed option via a dealer or an aftermarket kit installed by a professional. Some vehicles, especially newer models with advanced security or nonstandard transmissions, may have compatibility limits or warranty considerations.
Remote start systems allow you to start your engine remotely to warm or cool the cabin, precondition the climate, and unlock convenience features. Whether you can retrofit one depends on the vehicle’s electrical architecture, immobilizer system, and the existence of compatible wiring and sensors. This article outlines the practical routes, costs, and safety considerations involved in retrofitting remote-start capability.
Options to add remote start
There are several routes to energize a vehicle with remote-start capability after purchase. The right choice depends on your car, budget, and risk tolerance. The following overview highlights typical paths and what to expect.
- Factory/OEM remote start via dealership or new-car option: Some brands offer remote start as a factory option or through a dealer-installed package. Integration is usually seamless with the vehicle’s security system and climate controls, and it often preserves warranty when performed by an authorized dealer. Availability and pricing vary by model and region.
- Aftermarket remote-start kits installed by a professional: Aftermarket modules from reputable brands can be retrofitted to many vehicles, including push-to-start cars. A professional installer handles the wiring, immobilizer bypass, hood/door sensors, and integration with the car’s electrical system. Costs include parts and labor, and installation quality matters for reliability and safety.
- Smartphone-enabled aftermarket systems: Some aftermarket kits include a smartphone app or cloud service, giving you remote start, GPS, and status alerts. These typically require an add-on module and sometimes a cellular connection, with pricing reflecting hardware, subscription, and installation.
- Compatibility limits and things to watch: A few vehicles — especially those with highly integrated security, newer CAN networks, or nonstandard ignition setups — may require specialized solutions or may not be suitable for retrofit at all. In such cases, you may rely on a factory-equipped option if available or purchase a different vehicle that supports remote start more readily.
Considering options, costs, and the car’s security architecture is essential before committing to a retrofit. An informed choice reduces the risk of electrical faults, voided warranties, or warranty claims being affected by the modification.
Factory vs aftermarket considerations
This section compares the main routes to remote start. OEM options often offer the cleanest integration and better warranty protection, but they may be limited by model and market. Aftermarket installations provide broader compatibility but carry a higher risk of warranty issues and potential reliability concerns if installed by non-professionals.
Important considerations and safety
Before pursuing a retrofit, check transmission type, immobilizer interaction, warranty implications, and insurance requirements. Safety guidance includes never starting the car in a closed space, keeping children and pets away, and ensuring the vehicle’s gear is in park with the parking brake engaged when using remote start.
- Automatic transmission requirement: Most remote starts assume the car is in Park to prevent unintended movement. Some kits support anti-rollback setups, but manual trans models require careful assessment.
- Security and immobilizer compatibility: Some vehicles use more complex anti-theft electronics that require a bypass module, which can affect the vehicle’s security system if not properly installed.
- Warranty and insurance: Retrofit work can affect warranties or insurance coverage; verify with the dealer and your insurer before proceeding.
- Professional installation: A licensed installer reduces risk of wiring faults, false alarms, or engine damage.
- Maintenance and updates: Aftermarket systems may rely on software updates or app renewals; check ongoing support.
Setting realistic expectations and budgeting for installation and potential services will help you select the safest, most reliable option for your vehicle.
Summary
For cars without factory remote start, retrofit is usually feasible through a dealership option or an aftermarket installation by a qualified technician. The best path depends on your car’s configuration, your budget, and your tolerance for warranty and security considerations. Prioritize professional installation, confirm compatibility with the vehicle’s immobilizer, and choose a solution that aligns with safety guidelines to enjoy the convenience of remote starting with confidence.
