Interlock customer beware. (This is not a review for the shop that placed the device, the shop and mechanics were very helpful and kind. This is an Intoxalock review.) I went with this company because my attorney had a coupon for them, and I thought they were less expensive. After this experience, my attorney is no longer recommending this company, and I deeply regret giving them my business.
1. The price they quote monthly is false. They charge bi-weekly, not twice a month, so this means extra payments. They also charge random fees for things that are not used. This makes them the most expensive company out of all of the options I had.
2. The hold time can easily be 30-40 minutes, and many times, they will hang up on you once they're finally on the line. It is very difficult to talk to a real person. I always had to pretend I had a lockout just to get someone on the phone.
3. Once they're on the phone, their Indian accent is so thick that they're almost impossible to understand. The company also said they do not have the ability to transfer calls and do not have supervisors. So, if you can't understand them, you have to start the process all over again.
4. The Intoxalock workers will lie to you. They will tell you they're waiving fees, but then they charge the fees anyways. They will tell you that they can troubleshoot from their department, but then they will tell you they don't have that capability. They will tell you they made notes to your account for the next person to be able to help more effectivity, but then the next person will say there are no notes.
5. The interlock device started to have problems and they refused to fix the device and instead charged multiple lockout fees. The device would stay active long after my car was off and then go off randomly and that would cause a lockout. The volume stopped working and the device had to be monitored by sight.
6. When it was time to remove the device, they stated it was 60 dollars plus the 200 to take it out. They then charged another 340 dollars for random fees.
7. Worst of all for me was that the Intoxalock workers seem to have no compassion or willingness to help when something did go wrong. They were rude and would not help when things went wrong. There is no one you can talk to if you have a problem. There is no recourse when something goes wrong. There isn't a person you can go and see. You are completely in their mercy, and that is not something this company has.
Frequently Asked Questions About Intoxalock Ignition Interlock
How does an interlock device work?
An ignition interlock device (IID) is a small breathalyzer installed in your vehicle to prevent it from starting if alcohol is detected on your breath. Before driving, you'll blow into the device. If your breath alcohol concentration (BrAC) is below the programmed limit, the car starts. Periodic retests occur during your trip to ensure continued compliance. To read more on Intoxalock, you can read our ignition interlock device guide.
What is the cost of an ignition interlock device?
The installation of an ignition interlock device, often called a car breathalyzer, typically costs between $70 and $150. This one-time fee is paid at the start of your lease and covers the service center's labor to install the device in your vehicle. Payment is made directly to the service center at the time of installation. For more on cost breakdowns, you can read our cost of ignition interlock device guide.
How do I use my interlock device?
Using an IID is simple. To start your vehicle, blow into the device as directed. If the device detects no alcohol, your car will start. You may be prompted for "rolling retests" while driving, where you’ll blow into the device again to confirm compliance. How-to videos are also available on the Intoxalock mobile app.
Where do I get an ignition interlock device?
Ignition interlock devices can be installed at certified service centers nationwide. Intoxalock offers a convenient network of locations and helps you schedule an installation appointment near you. Visit our Intoxalock locations page or call us to find the nearest service center and begin the installation process.
How long will my installation take?
Installing an ignition interlock device typically takes 1-2 hours, depending on your vehicle type. Certified technicians ensure the device is properly installed and provide you with training on how to use it. Contact Intoxalock for an appointment and an accurate time estimate for your installation.
What happens if I fail a breath test on my ignition interlock device?
If you fail a breath test, your vehicle will not start, and the device will log the event. Depending on your state’s regulations, multiple failed tests may trigger additional penalties, such as lockouts or reporting to your monitoring authority. Intoxalock devices allow you to retest after a short wait if alcohol is no longer detected. Always follow your state’s guidelines to remain compliant.
Can I install an ignition interlock device in a vehicle I don’t own?
Yes, in most cases, you can install an ignition interlock device in a vehicle you regularly drive, even if you’re not the registered owner. However, the vehicle owner must provide consent for the installation. Intoxalock works with you and the owner to ensure compliance with state regulations and the successful setup of the device.
What should I do if my ignition interlock device locks me out?
If your ignition interlock device locks you out, it’s usually due to missed tests, failed tests, or state-specific requirements. Intoxalock offers a simple lockout override process in most cases to help you get back on the road quickly. Contact Intoxalock customer support for assistance and to understand the steps needed to resolve the issue.
