Keyless Ignition & Entry Systems for Cars and Trucks

What Is a Keyless Ignition System?

A keyless ignition system replaces or supplements your key-turn ignition with a push button, a key fob, or both. Most push to start kits combine a push-button ignition switch, a control module, wiring harnesses, and often keyless entry. With an RFID proximity ignition setup, you keep the fob near the vehicle, press the button, and the engine starts.

These kits sit within our keyless entry & ignition systems category, next to keyless entry systems that lock and unlock doors with a remote. If you're upgrading security at the same time, you can pair a keyless ignition kit with vehicle alarms.

Kits fall into two broad groups. Universal kits adapt to many 12V vehicles, while vehicle-specific kits are built around one platform. Knowing which group you need narrows your search fast and helps you avoid ordering a kit that won't fit.

Types of Keyless Ignition Kits and Parts

This category covers several part types, and each one solves a different problem:

• RFID proximity ignition kits that start the engine when the fob is near and you press the button
• Push button start kits with a switch, control module, and wiring harnesses
• Vehicle-specific remote start kits from Kleinn Automotive Accessories
• Remote keyless antennas, passive entry antennas, replacement remotes, and key covers from Mopar Accessories, such as 2012-13 Fiat 500 parts
• Keyless remote cases and case repair kits from Dorman Products for select Honda, Chevrolet, Buick, Mazda 6, and Hyundai Elantra applications

For RFID proximity-based ignition kits, remote door entry systems, and direct-fit start button replacements, look to Digital Guard Dawg, Ididit, and Ford Performance. Dorman cases also cover select Pontiac, Saturn, and Oldsmobile remotes. Match the part to the job, whether you're adding a new feature or repairing a factory remote.

How a Push To Start Conversion Kit Is Installed

Most push to start conversion kits wire into your existing ignition circuits instead of replacing them outright. The Flaming River push button start system is a good example. Its instructions on JEGS explain that it supplements the standard ignition switch and is wired in parallel to it.

Three relays control the accessory (ACC), ignition (IGN), and starter (ST) circuits through an illuminated push button. The maker recommends keeping your stock ignition switch and wiring intact as a backup. That way, you still have a working key if you ever need it.

Before you start, identify each circuit on your vehicle. If you're new to tracing wires, our guide on how to read automotive wiring diagrams helps you find the right wires before you splice anything. Universal and vehicle-specific kits can differ in how much wiring work they need, so read the instructions before you order.

Push Button Starter Switches for Race and Custom Builds

A standalone push-button starter switch is a momentary switch that sends power to the starter only while you hold it. It doesn't replace your full ignition system. In race and custom builds, it's often paired with a toggle or ignition switch that powers the ignition circuit first.

You can shop push-button starter switches in our switches category. Many builders mount them in switch panels to keep starter, ignition, and accessory controls in one spot. That setup suits race cars, hot rods, and custom dashes where a factory key cylinder doesn't fit the build.

Choosing between a standalone switch and a full keyless ignition kit comes down to what you need. A switch handles starting only. A kit adds a control module and, often, keyless entry or proximity features. If you want push-button convenience with proximity or remote functions, a kit is the better fit.

How To Find the Right Keyless Ignition Kit for Your Vehicle

Start with fitment: use the Add a Vehicle tool on JEGS to confirm a keyless ignition kit fits your car or truck. Most 12V vehicles can accept an aftermarket push-button start, but compatibility varies by kit. Some kits are vehicle-specific, so check the listing details too.

Next, decide which features you want: push-button start only, RFID proximity ignition, remote start, or keyless entry. Then check what's already working on your vehicle. If your factory system is fine and only the remote is worn, a replacement key fob or case may be all you need. That saves you from rewiring a system that still works.
