How To Deactivate Honda Immobilizer

Immobilizers were first introduced in 1992 and have developed into state-of-the-art anti-theft systems that are included in most vehicles made in the last 20 years, including Hondas vehicles.

To deactivate a Honda immobilizer, insert the key into your ignition and switch to the on position then to the lock position.

Remove the key, then put it back in and turn to the on position. This should automatically reset your Honda’s immobilizer.

If your Honda’s anti-theft systems are not working then you will want to know how to deactivate the honda immobilizer until you fix the issue.

You will need to shut off the system so your vehicle will start and run as normal as a damaged or dead battery in your immobilizer chips will cause the vehicle to not run correctly.

Before we look into how to deactivate the Honda immobilizer let’s take a look at how this system in your vehicle functions.

What is An Immobilizer?

A car immobilizer (also known as an engine immobilizer) is a piece of electronic security equipment that is designed to prevent vehicle theft through hot-wiring.

A transponder chip in the key fob or smart key of your vehicle has to intercommunication with the car’s immobilizer and convey a passcode before your vehicle will start.

This is why car dealerships have started to increasingly use key fobs or smart keys on new vehicles instead of a physical key as it provides an extra level of safety whilst still maintaining all the functions you would need such as trunk access, unlocking doors, and sometimes to remotely start your vehicle.

If your immobilizer does not receive the right code when you attempt to start the engine then this will usually sound an alarm and some systems will notify a security company if it seems like theft is taking place.

Here are some methods to try if you wanted to know how to deactivate the Honda immobilizer.

Method One

If your vehicle has had an attempted break-in or the anti-theft system has been triggered for any reason then you will be unable to start it. Here’s how to disable it,

With your ignition off check your anti-theft light on the dashboard, it will either be blue or red, Turn your ignition on and check again if the light is illuminated. If it is no longer blinking then turn the key over to the off position and leave it to sit for up to 5 minutes to give it time to reset Try to start your engine.

Method Two

If you have a physical key for your vehicle then you can try and use this to disable your anti-theft systems and reset them.

Insert the key into your door lock on the driver’s side Turn the key to unlock your door and leave it like this for 30 seconds before trying to start your vehicle again. If this doesn’t work then some models may require a slightly different process such as turning the key back and forth multiple times before it recognizes the key is present in the cylinder and disables your Honda’s immobilizer.

Alternative Methods

If you find neither of these methods has worked to disable your Honda’s immobilizer then other users have reported that these methods have worked for them.

You can try pressing your key fob 5 times and hitting the lock button then waiting a few moments to see if this will reset your immobilizer.

Alternatively, you can try leaving your Honda with the ignition on for 10 minutes to reset the system or manually open your car door with the key and turn it to unlock then locked twice before leaving the car to run for 10 minutes.

Where Is My Honda Immobilizer Code?

If you need the immobilizer code for your Honda then you will need to have your service book or user manual to hand. These books will have a dedicated section for your vehicle’s specific immobilizer and there you will find the code.

If you cannot locate the code then you can sometimes ask a car garage to do this for you as long as you can provide sufficient evidence you are the owner of the vehicle.

Common Honda Immobilizer Faults

Honda vehicles are commonly known for suffering from immobilizer faults.

Most commonly reported is an issue with the transmitter which will then affect the immobilizer which will need a replacement as a more economical option, but you can also disable it however you will no longer be covered by your insurance if it gets stolen and you will be less protected against theft.

The second most common immobilizer fault is with the receiver which has a worn transponder that will need replacing by a technician.

Can You Bypass a Honda Engine Immobilizer?

The quick answer is yes you can and here is a video that shows you exactly how to do it step by step.

FAQs

How do you fix an immobilizer problem?

How do I know if my car is in anti-theft mode?

If your car’s anti-theft light is flashing when you try to start your vehicle and the engine doesn’t crank then your vehicle has an issue with the anti-theft system.

Conclusion

Having an issue with your Honda’s immobilizer is a regularly reported issue and there are ways you can reset this system to enable you to drive your vehicle safely.

The first thing you should try to deactivate a Honda immobilizer is to insert the key into your ignition and switch to the on position and then to the lock position. Remove the key, then put it back in and turn to the on position. This should automatically reset your Honda’s immobilizer.

We have listed several methods that should hopefully answer the burning question of how to deactivate the honda immobilizer.

If you have purchased a Honda second hand then make sure you have access to the immobilizer code to prevent these issues from reoccurring in the future and leaving your engine without power.

Tips on How to Prevent Your Honda From Being Stolen

Nothing ruins your day faster than finding your car missing from its parking spot. And if you are a Honda owner, you should realize that this is not an idle worry. The 2016 Hot Wheels report from the National Insurance Crime Bureau ranks the top 10 cars most beloved by thieves, and the Honda Accord is number one. In 2015, thieves stole 52,244 Accords, with model years 1994, 1996 and 1997 proving the most popular. The second spot goes to the Honda Civic, with 49,430 thefts that are topped by model years 1997, 1998 and 2000.

Will an immobilizer save your car from being stolen?

Automobiles are getting ever smarter, and cracking them with a crowbar and a screwdriver is getting ever more difficult. Statistics back up that assumption: According to research from Jan C. van Ours and Ben Vollaard highlighting car theft and recovery data, vehicle theft decreased by 70% between 1995 and 2008 in the Netherlands and by as much as 80% in Great Britain.

One of the causes of the decrease is the ubiquitous introduction of so-called “immobilizers.” Immobilizers, however, are just as susceptible to cracking as any other relatively complex technology. Cybersecurity researcher Wouter Bokslag chose this as the subject of his Master’s thesis and presented the results of his research at the 36th Chaos Communication Congress (36С3).

What an immobilizer is

In a nutshell, an immobilizer tries to ascertain if the person behind the wheel is a rightful owner. If it cannot be sure, it simply will not let the car start. The recognition process is imperceptible to the lawful owner; it happens within a fraction of a second, with no user participation.

The world’s first-ever immobilizer was patented as early as 1919. At the time, the driver needed to connect contacts in a certain order, and if the order was wrong when the car was started, an alarm went off.

Today’s immobilizer consists of two key parts: a transponder in the ignition key and a receiver in the car itself. When someone attempts to start the engine, the vehicle sends a request to the key. If the key returns the correct predefined signal, the immobilizer sends a command to the engine control unit to start. Without the right signal, you can’t start the car.

Hitag2, DST40, and Megamos Crypto were some of the first transponders. Having been scrutinized over the years, they are now considered insecure. You can read about the shortcomings of Hitag2 here, and those of Megamos Crypto here.

In the final decade of the 20th century, immobilizers proliferated. They became mandatory in the EU states in the late nineties, and other countries gradually followed suit. If we can believe those countries’ reports, immobilizers contributed to a significant decrease in auto theft.

Carjackers strike back

Car theft certainly did not stop there, though. Following a familiar pattern, once immobilizers went mainstream, an arms race between criminals and car brands ensued. As cars got smarter, offenders kept up, and immobilizers proved fairly easy to trick. Successful cracking attempts became frequent, and car theft’s long-standing, steady downward trend reversed around 2010. Great Britain’s car theft rate reached an eight-year high in 2018, and many other countries saw a similar trend: a plunge until 2010 followed by a slight rebound or a plateau.

Expensive luxury brands persisted as the most frequently hijacked cars. Cybersecurity researchers focused on those brands as well, but despite huge budgets, their studies were disappointing.

If an expensive luxury car can be stealthily cracked within ten seconds, what does that say about higher-volume models that most people drive, you might reasonably ask.

Studying immobilizer security

In his study, Bokslag tried cracking three cars by popular brands. None of the cars was new; they all dated back to around 2009. The models were inexpensive B-class hatchbacks — the aforementioned higher-volume models. According to the authors of the study, many newer cars use similar antitheft systems.

Bokslag used the following approach:

Gain access to CAN bus traffic. The CAN bus is what the internals of most current cars use for communication. Read messages that the immobilizer components exchange. Get a hold of the engine control module (ECM) or body control module (BCM) firmware. Identify the algorithm used in the messaging. Use the previously obtained data to prove that you can start the car without an original key.

Step one is fairly easy: Access to the bus is available through the standard OBD II port. All cars from after the year 2000 have it, and it serves the purpose of diagnostics. Once inside a car, you have access to the interface.

One could get the firmware in a hundred ways, from fairly complex techniques to a simple Internet download. That’s right: The firmware for many cars is available online; manufacturers provide it for diagnostics or maintenance.

Well, that’s fine as long as all traffic is reliably encrypted. But herein lies the biggest disappointment: The first two immobilizers were using very week encryption. On the first car, it took only seconds to retrieve vehicle security code, which allows for the authorization of a new key and subsequently disables immobilization. Obtaining the second test car’s security code took as many as 4,000 attempts, or about 15 minutes.

The third specimen was actually tougher — its immobilizer protocol did not have any obvious flaws and was not broken. However, the researcher determined that the key’s chip emulates the PCF7935 transponder, which is similar to the one used in the Hitag2. Using Hitag2’s known weaknesses, you can start the car in just 6 minutes without any need to mess with cryptography.

All three systems are still around, and installed in some cars built in 2019.

What do we do?

Immobilizers are really effective against more conservative offenders who are still using mechanical techniques. They are, however, no match for the more sophisticated among carjackers — in the mass-produced segment anyway.

Therefore, odd as it may seem, a possible recommendation for automobile owners is to remember their roots and not to discard technologies from the eighties and nineties. To break into an electronic security system supplemented with a mechanical steering wheel lock, a carjacker needs the skills to crack both electronics and mechanics.

You still might cross paths with a skilled “two-in-one” carjacker, but at a minimum, doubling up on your security will make stealing your car a little harder than the one next to it. As they say, you don’t have to outrun the bear — just be faster than the other guy.

That said, car manufacturers remain carjackers’ key adversaries, but they are cybersecurity beginners in many ways. Unfortunately, they use proprietary — and often unsophisticated — encryption algorithms that disregard industry standards, and antitheft systems become hopelessly obsolete by the time the cars they protect hit the market.

Despite that, we and others have taken some initial steps to improve automobile security. For some years, we have partnered with AVL, the largest independent manufacturer of automotive systems to make modern connected cars much more secure.
