So, how to jump start a car with intoxalock? Jump-starting a car might sound a bit complicated, especially if you have an Intoxalock device installed, but with the right guidance, you can do it without any trouble.

What is An Intoxalock?

Intoxalock, also known as an ignition interlock device (IID), is a breathalyzer device installed in a vehicle that prevents the engine from starting if the driver has been drinking alcohol. It is a breath alcohol testing device connected to a vehicle's ignition system.

Here's how it works:

1-Breath Sample: The driver must blow into the Intoxalock device before starting the car. It measures the alcohol content in the driver's breath.

2-Alcohol Content Analysis: The device analyzes the breath sample to determine the blood alcohol concentration (BAC) level. The car will start as usual if the BAC level is below a predetermined threshold (usually 0.02% or 0.04%).

3-Engine Ignition: Alcohol levels exceeding the limit are detected in breath samples, the device prevents the engine from starting. The vehicle remains immobilized until a sober breath sample is provided.

4-Periodic Retests: Additionally, the Intoxalock device requires periodic retests while the vehicle is in operation. These tests ensure that the driver remains sober during the journey.When the driver fails a retest, the horn may sound, and lights may flash until the engine is turned off. It ensures that the driver cannot continue driving under the influence.

How to Jump Start a Car with Intoxalock | Step-by-Step Guide

You should know the answer to “how to jump start a car with intoxalock?” Having an Intoxalock device in your car doesn't mean you're stuck if your battery dies. You can jump-start your car and get back on the road with the right steps. Here's a simple step-by-step guide to help you jump-start your car safely and effectively with an Intoxalock device.

Step 1: Getting Ready

The first step is to find another car to help you out. This car will give your battery the boost it needs to start your engine. Make sure both cars are parked close but not touching. This is important for safety. Also, make sure both cars are turned off. It's like putting both cars to sleep before waking them up again.

Step 2: Opening the Hood and Find the Battery

To give your car a jump-start, you need to open the hood of both cars. Think of it like opening the bonnet of a toy car - you need to see inside to fix it.

Once the hoods are open, it's time to find the battery. In most cars, the battery is a rectangular box with two metal bits sticking out, one red and one black. These metal bits are like the battery's hands; they need a little help to shake hands with the helping car.

Step 3: Connecting the Jumper Cables

Now comes the part where you connect the helping car to your car. But wait, we can't just plug them in randomly - there's a special way to do it. It's like connecting puzzle pieces; they need to fit just right.

First, find the jumper cables. These are like the magic strings that will bring your car's battery back to life. Jumper cables have clamps at the ends, like the clips you use to hold a stack of papers together.

One of the clamps is red, and the other is black. The red clamp is like the positive side, and the black clamp is like the negative side. Here's the trick: you need to connect the red clamp to the positive terminal of your car's battery. It's usually marked with a plus sign, just like in math. Then, the other red clamp goes to the positive terminal of the helping car's battery. It's like making a bridge between the two cars' batteries.

It's the black clamp's turn. Connect the black clamp to the negative terminal of the helping car's battery. It's marked with a minus sign. But here comes the important part: don't connect the other black clamp to your car's battery.

Instead, find an unpainted metal part under your car's hood. This can be a metal bracket or a shiny bolt. Connect the black clamp there. This is like grounding your car, giving it a safe path for the electricity to flow without any issues.

Step 4: Starting the Helping Car

Now that the jumper cables are all set up, it's time to wake up the helping car. The person helping you needs to start their car's engine. Once the helping car's engine is running, it's sending good vibes (or electricity, in this case) through the jumper cables to your car's battery.

Step 5: Giving Your Car a Boost

It needs some time to get back on its feet. Let the helping car run for a few minutes. This is like allowing your car's battery to catch its breath and gather some energy. While waiting, your car is taking a power nap before it's ready to roll again.

Step 6: Starting Your Car

It's the moment of truth after a few minutes. Try starting your car. Turn the key, and if everything works out, your car will roar to life, ready to hit the road again. It might take a couple of tries, but be patient. Just like waking up from a nap, your car might need a moment to fully wake up.

Step 7: Disconnecting the Jumper Cables

Congratulations! Your car is running again, thanks to the other car's helping hand (or engine). Now, it's time to say goodbye to the jumper cables. But remember, you can't just unplug them any way you like. There's a special order to follow. First, remove the black clamp from the unpainted metal part of your car.

Then, remove the black clamp from the helping car's battery. Next, remove the red clamp from the helping car's battery, and finally, remove the red clamp from your car's battery. It's like politely saying goodbye, one step at a time. Now you know - how to jump start a car with intoxalock?

Additional Tips

Sometimes, even after all these steps, your car might still be grumpy and not start. Don't worry; it happens to the best of us.

1. Check Your Battery Carefully

Before you attempt to jump-start your car, take a close look at your battery. Check for signs of damage like leaks or swelling. Your battery might need to be replaced if it looks odd. There is a risk of damaging the battery when jump-starting it and it might not work. Keeping an eye on your battery's health is like caring for a plant – the healthier it is, the better it functions.

2. Be Patient and Persistent

Sometimes, your car needs a bit of time to wake up. You don't have to worry if your car doesn't start immediately. Wait for a few minutes, and then try again. It's like waiting for your computer to start – sometimes, it just needs a moment. If, after a few tries, it still doesn't work, it's okay. Stay calm and consider asking for help from a professional. They're like car doctors; they know just what to do.

3. Take Care of Your Car Regularly

Keep an eye on your battery's connections – they should be clean and tight. Regular maintenance can help your battery live longer. It's like eating healthy and exercising to stay fit. A well-maintained car is less likely to surprise you with a dead battery.

These small devices store energy and can bring your car back to life. They're handy, especially in emergencies. Think of it as having a spare battery in your glove compartment.

5. Ask for Professional Help

Call the experts if all else fails or you're unsure what to do. Mechanics are like car wizards – they know the ins and outs of vehicles. They can help you jump-start your car safely and ensure everything is in shape. It's better to ask for help and be safe than to guess and risk damaging your car or Intoxalock device.

6. Know Your Intoxalock Device

Take some time to read the manual of your Intoxalock device. It's like reading a guidebook for a game – it tells you all the important rules. Understanding your device can prevent accidents during a jump-start. It's like knowing the right buttons to press. Familiarizing yourself with your Intoxalock device's features can make jump-starting much smoother.

Safety First

The idea of jumping-starting a car might seem like a fun experiment, but it is crucial to be safe while doing so. Just like wearing a helmet when riding a bike keeps you safe, there are rules to follow when jump-starting a car. Never let the red and black clamps touch each other; it's like making sure your toys don't collide and break.

Also, if the battery looks weird, like if it's leaking or damaged, don't touch it. Call for help from an adult or a professional. Lastly, it's best to wait if the engine is too hot. Similarly, a hot engine can be dangerous, so patience is better.


Car jump-starting might seem challenging, especially if your car has an Intoxalock device. But with the right steps and patience, you can bring your car back to life. Just remember the helping car, the jumper cables, and the special order to connect and disconnect them.
