How Long Does It Take to Install a Push Start System?

One of the most common questions people ask before upgrading to a push start ignition system is: "How long does it take to install?"

The answer depends on your experience level, your vehicle, and how well you understand the wiring.

For most DIY installers, a realistic estimate is 3–6 hours. That number can stretch to a full weekend if something goes wrong. It can also shrink to under 90 minutes if you've done it before.

For a complete walkthrough of the entire process, start with our step-by-step push start installation guide.

Average Installation Time by Experience Level

• Beginner DIY installer: 3–6 hours — see our beginner-friendly installation guide for a detailed walkthrough
• Experienced DIY installer: 1–2 hours
• Professional shop: Usually under 90 minutes for the basic push start function

Wondering whether a push start system is easy to install? We break down the difficulty level and what to expect at each skill level.

If you've never touched vehicle wiring before, don't assume it will be a two-hour job. Read our honest take on why push button start installation takes longer than YouTube shows.

One owner documented his own experience in "I Thought Installing a Push-to-Start System Would Take Two Hours. It Didn't." — worth reading before you start.

What Makes Installation Take Longer?

Every vehicle is different. Several factors can significantly extend installation time:

• Factory immobilizer systems — Toyota, Honda, Ford, GM, and Dodge all use different anti-theft systems that may require a bypass module
• Vehicle age and wiring condition — previous owners, alarm installers, and stereo shops may have modified the harness
• Difficult-to-reach ignition harnesses — some vehicles require removing more trim than others
• Adding remote start or PKE keyless entry — these are separate functions that require additional wiring and testing
• First-time installation — everything takes longer when you're learning

What Makes Installation Faster?

Modern push start kits often include:

• Plug-and-play style harnesses
• Pre-labeled wiring
• Universal 12V compatibility
• Compact control modules
• Vehicle-specific wiring diagrams

If you're adding remote start functionality at the same time, our guide on how to install a universal 2-way remote start system covers the additional steps.

Step-by-Step Installation Overview

Step 1 — Disconnect the Battery

Always disconnect the negative battery terminal before touching vehicle wiring.

Step 2 — Remove Dashboard Panels

Carefully remove the steering column trim and dashboard covers. Take photos as you go so you can reassemble everything correctly.

Step 3 — Locate Ignition Wiring

Find the ignition harness behind the factory key cylinder. Identify constant power, ACC, IGN, and starter circuits.

Step 4 — Connect the Push Start Module

Connect the system according to the wiring diagram. If your vehicle has a factory immobilizer, verify whether a bypass module is required.

Step 5 — Mount the Start Button

Choose a clean, visible location for the push button. Avoid placing it where it could be accidentally pressed.

Step 6 — Test the System

Reconnect the battery and verify all functions:

• ACC mode works
• IGN mode works
• Brake + START starts the engine
• Engine shuts down correctly
• Remote start works (if installed)
• Lock and unlock work (if installed)

If something doesn't work, our troubleshooting guide if your push start isn't working will help you diagnose the issue.

Should You Install It Yourself or Pay a Professional?

If you're comfortable with basic electrical work and have a multimeter, a DIY installation is realistic.

If you're not, professional installation usually costs far less than the damage caused by miswiring a vehicle.
