How to Program a Key Fob for Push-to-Start Cars: Step-by-Step Guide

Published Date: Nov 27, 2025

Programming a push-start key fob can feel confusing, especially with modern vehicles. If you’re searching for how to program a key fob push start, you’re not alone — many drivers want a clear, reliable way to handle it themselves. Some cars support DIY key fob programming, while others may require special tools or expert help. In this guide, we’ll walk through the typical process, common issues to watch for, and when it makes sense to contact a trusted automotive locksmith like Sure Lock & Key.

Can You Program a Push-to-Start Key Fob Yourself?

In many vehicles, especially older models, car remote programming can be done without special tools. This is called onboard programming, and it allows you to register a new or replacement fob using only in-car steps. The process can vary by make and model, but the general method includes inserting the fob, cycling ignition modes, and pressing certain buttons in a sequence.

However, newer vehicles with keyless start fob systems or push-button start key programming often require diagnostic tools or encrypted software access. In those cases, you’ll need help from a dealer or a certified automotive locksmith.

To understand more about how these systems work, take a look at our article on understanding key fob programming.

Step-by-Step Method: How to Program a Push-to-Start Key Fob

Before starting, check your owner’s manual. Not all cars allow DIY key fob programming, especially push-start models.

Step 1: Get Ready

Sit in the driver’s seat with all doors closed. Have all key fobs you want to program ready.

Step 2: Turn On Accessory Mode

Press the “Start” button (without your foot on the brake) to turn on the ignition to “Accessory” or “On.”

Step 3: Enter Programming Mode

Depending on your vehicle:

Some require pressing the “Lock” and “Unlock” buttons together.
Others need the key fob inserted into a slot or placed near the start button.

Step 4: Program the New Fob

Press the required button combination as instructed. The car may beep or flash lights to confirm pairing.

Step 5: Test and Exit

Turn off the ignition and test all buttons. Try starting the vehicle to make sure the keyless entry remote works properly.
