How To Program A New Ignition Lock Cylinder

Ignition locks are one of the most important safety features on a car. If someone were to steal your car and drive off with it, an ignition lock would prevent them from starting the engine. Unfortunately, these locks can be easily broken, which is why it’s important to know how to program them if you want to keep your car safe. In this blog post, we will teach you how to do just that. ###

What is an Ignition Lock Cylinder?

An ignition lock cylinder is a small, cylindrical device that holds the key to your car’s ignition. When you turn the key in the ignition, the cylinder rotates and releases the key, preventing anyone else from starting your car. If your cylinder needs to be replaced, it can be done at a dealership or by yourself using a few simple tools.

How to Program a New Ignition Lock Cylinder

If you have a new ignition lock cylinder and need to program it, follow these steps:
1. Remove the OEM key from the ignition.
2. Insert the key into the “programming” slot on the side of the new cylinder (arrow pointing down). The programming light should turn green in response.
3. Turn the key all the way to the left (counterclockwise) until you hear a “click.”
4. Turn the key all the way to the right (clockwise) until you hear another “click.” This will confirm that you have entered correctly into programming mode.
5. Push and hold down both power buttons for five seconds each while turning the key to your desired setting. The programming light will turn off when successful, or stay on if there are errors or if you continue to try to change modes after programming is complete.

What To Do If Your Car Won’t Start

If your car won’t start, there are a few things you can do. Check the battery, the key, and the ground connection. If all of those seem to be working, check the cables that connect the ECU (electronic control unit) to the ignition switch. A bad cable can cause your car to not start. If everything else looks good, you may need to replace the ignition switch.


If your car’s ignition lock is no longer functioning, then you’ll need to replace the cylinder. This article will show you how to program the new ignition lock cylinder. Be sure to have a Phillips head screwdriver and an adjustable wrench ready before proceeding.
