Late-model Honda vehicles, especially those equipped with push-to-start systems, have become increasingly frequent targets for sophisticated theft techniques like the CAN Bus attack. In this method, thieves gain access to the car’s internal wiring—often through the wheel well or behind a headlight—and inject fake signals into the Controller Area Network (CAN), tricking the car into unlocking and starting. Many Hondas are particularly vulnerable because of how their electronic systems are configured and the accessibility of key CAN wires. Thieves can gain access and quietly drive off without ever needing to break a window or sound an alarm. With these cars you are almost always dealing with skilled thieves often involved in organized crime. They are also frequently stolen using methods like the relay attack, where thieves steal your key’s signal to unlock/start your car, as well as attacks using key programmers and other devices connected to the OBD port. Don’t forget to read our full articles on Layered Defense for Auto Theft Prevention and Late Model Car Theft- “Car Hacking” but here are some security measures that will be good for your newer push-start Honda:

Our Recommended Layered Defense Setups

Choose the setup that’s best for you, your budget and your vehicle. There are many great products not listed in these examples that you may decide to use (see other products below). Just make sure to choose products you won’t mind using consistently.

What is important to include when building the layered defense for your Honda (or Acura) is:

1. An immobilizer that will help prevent it from starting. For example IGLA, Ravelco, Immobilizers built into alarm systems, etc. Most immobilizers can be used together to further reduce the chance they will be overridden.
2. Protection against relay thefts, like a Faraday box or pouch
3. Physical blockage of the OBD port
4. Visible deterrent like a club
5. (Preferably) a 2-way alarm system to notify you of theft attempts in real-time

Aftermarket Alarm Systems

Installing an alarm system on a late-model Honda can be a smart way to help prevent theft, especially given how frequently these vehicles are targeted. However, it’s important to invest in a high-quality aftermarket system and have it professionally installed. Basic factory alarms that just trigger the horn are often ineffective and simply get ignored. While the loud noise might startle an inexperienced thief, many seasoned criminals know how to bypass or avoid triggering factory systems in certain Honda models. Fortunately, advanced aftermarket alarms offer more robust protection, provide you with an early warning, and require a little more guesswork for thieves to disable. These systems often include features such as:

• Starter Immobilizers that prevent car from being started if alarm is armed- even with the key.
• 2-way notifications that alert you via your key fob or phone when your alarm has been set off.
• Shock sensors that set off alarm when vehicle is hit
• Audio glass break sensors that listen for your glass being broken
• Tilt Sensors that can detect if your vehicle is being towed or jacked up to steal wheels.
• Built in GPS
• Blinking light for deterrence

Immobilizing Devices

Installing an immobilizing device is a crucial part of the anti-theft plan for your Honda. Whether the thieves try and hack your CAN Bus, or clone your key, you need an aftermarket system to help thwart their attempt to start the vehicle. Here are some different options of immobilizing devices that can be installed in your vehicle:

• IGLA Anti-Theft System– The IGLA Anti-Theft System is a discreet, advanced immobilizer designed to stop vehicle theft by preventing the engine from starting unless a unique PIN sequence is entered using factory controls, such as steering wheel buttons or radio buttons, etc. or by using the Bluetooth key fob or smartphone. On late-model Hondas, the system integrates directly with the vehicle’s electronic network, making it highly resistant to common theft methods like relay attacks, key cloning, and CAN bus exploitation. Because IGLA does not add visible hardware and leaves no obvious clues, it is extremely difficult for thieves to detect or bypass. (Read more about IGLA here.)
• Ravelco– The Ravelco is another quality immobilizer option that is deeply integrated into your cars wiring. It works by using a unique plug, typically located under your dash or steering wheel, that is discretely wired deep into your vehicle’s wiring harness, that typically disrupts multiple systems when the plug is removed, leaving your vehicle unable to start. It is important to remember that the Ravelco will not work if you fail to remove the plug and take it with you when you leave your vehicle. (Read more about Ravelco here.)
• Certain types of aftermarket alarm systems– As mentioned earlier, many aftermarket alarm systems also function as immobilizers. While they are generally somewhat easier to bypass than dedicated options like IGLA or Ravelco, they are most often effective at slowing a thief down enough to make them abandon the attempt. These systems are also simpler to use on a daily basis, since arming and disarming is typically done by pressing the lock or unlock button on your factory remote or alarm fob. (Read more on alarm systems here.)
• Kill switches– (View on Amazon) Kill switches are a low-cost way to add some theft protection, but they are not as effective as more advanced immobilizers. They work by wiring a hidden toggle, button, or magnetic switch into the vehicle’s starting circuit, preventing the engine from cranking when the switch is turned off. The biggest drawback is that they do not use a unique key or remote, so if a thief locates the switch, the vehicle can be started again. If you go this route, take extra care to conceal the switch and consider installing a decoy, non-functional switch under the dash to confuse would-be thieves. Most mechanics or experienced DIYers can install a kill switch without much difficulty. (Read more about kill switches here.)
• JDI Ghost Power RFID Kill Switch– The JDI Ghost Power RFID kill switch is a discreet and effective anti-theft solution. It uses a concealed RFID reader and interrupts the ignition system unless the programmed RFID tag is presented when starting, functioning as an invisible kill switch. (See more about Ghost Power Here)
• JDI Ghost Lock Tracking System/Remote Disable– The Ghost Lock is a tracking device that also allows you to remotely disable the fuel pump in the event your Honda has been stolen or if you want to add an extra layer of protection against starting. (See more about Ghost Lock Here)
• Remote Battery Disconnect Switches– (View on Amazon) Remote battery disconnect switches are a low-cost, easy-to-install theft deterrent. They work by using a remote-controlled switch on the negative battery cable to cut power to the vehicle. The downsides are notable: disconnecting the battery also disables alarm systems, and a thief who gains access to the hood can bypass the device. That said, they can still be effective for budget-conscious protection, as many thieves will not take the time to diagnose a vehicle that suddenly has no power. A disconnected battery can also interfere with relay attacks, since thieves will be unable to unlock the vehicle and may assume their signal is not working. (Read more on remote battery disconnect here.)
• Cyclops TAM– The Cyclops TAM replaces a factory relay in your vehicle and can be enabled or disabled using the included remote. When switched off, it prevents the car from starting unless the relay is reinstalled or the system is turned back on with the remote. Because it is located in the fuse panel, a determined thief with time and mechanical knowledge could potentially bypass it. Even so, it remains a solid, cost-effective option that adds meaningful protection and is simple for most owners to install themselves. (See more here)

Faraday Pouch for Push to Start Keys

Many Hondas are stolen by thieves using the relay attack, where they use special devices to clone your push-start key’s signal from as far as 30 feet away. A faraday pouch is a little pouch that can block this signal from being detected, you can also get a faraday box for when you’re at home. The downside is that you will not be able to use the convenient functions of proximity keys while utilizing the pouch such as unlocking or starting your car with the key in your pocket, but that’s better than coming out to no car at all. While it’s best to use one all the time, even only using a Faraday Box while you sleep at night can do a lot to reduce your risk of theft for a small investment. Keep in mind that the faraday pouch will not protect against theft methods like the CAN BUS attack or cloning your key using the OBD port and a key programmer. (See more about faraday pouches here.)

OBDII Port Lock

An OBD port lock is an effective way to stop or at least delay thieves who rely on access to the diagnostic port to steal your Honda. These devices physically block the port and require a key to remove. Even if a thief attempts to force it off, there is a good chance the port will be damaged, which still prevents it from being used. While replacing an OBD port is inconvenient, it is far preferable to replacing an entire vehicle. Given their low cost, OBD port locks are an easy addition to any layered anti-theft approach. (See more about OBD locks here.)

Removing a Fuse or Relay

A no-cost way to prevent your vehicle from starting is to remove a critical fuse or relay and keep it with you. Most thieves will not waste time diagnosing a no-start condition and will move on to another vehicle. If you are mechanically inclined, your owner’s manual can help identify a suitable fuse, or a mechanic can advise you. Be careful not to remove a fuse tied to other security systems or one that could cause damage if the car is started without it, and make sure you do not lose it. While dedicated immobilizers are far more convenient, this can be a useful extra measure for long-term parking or tight budgets.

Honda Radar Shield by Miller Cat

Available for late model CR-Vs, Accords, and Pilots, the Honda Radar Shield by Miller Cat blocks a popular point of entry for CAN Bus attacks. This can be a good addition to your security plan but should not be solely relied on for theft prevention, as it will not protect from relay attacks/ key cloning and there are other spots where thieves could access the CAN Bus. (See more about CAN Bus shields here)

“The Club” Steering Wheel Locks

Steering wheel locks, often referred to as “The Club,” are inexpensive and widely used theft deterrents. While a determined thief can still defeat them by cutting the lock or even the steering wheel, the highly visible barrier is often enough to push criminals toward an easier target. Because of their low cost and strong visual deterrence, they make a sensible addition to a layered security setup, even if you already use more advanced solutions like IGLA, Ravelco, or an aftermarket alarm system. (Read more about clubs here.)

Brake Pedal Locks

Brake pedal locks come in a variety of designs, but all function by preventing the brake pedal from being pressed, which can stop the vehicle from being shifted or started. This adds an extra obstacle for a thief to overcome, though they are less visible than steering wheel locks and can be slightly more inconvenient for daily use, since installation often requires standing outside the vehicle. (Read more about pedal locks here.)

“Boots”/Wheel Locks

You have probably seen a vehicle “booted” for parking violations, and similar wheel locks are available for personal use. While they can be bulky and inconvenient for everyday driving, they are an effective deterrent when you are willing to use them. Wheel locks add time, effort, and risk for a thief, making them a good complement to other security measures, especially if your vehicle will be left unattended for an extended period, such as during a vacation. As with any anti-theft device, the key is choosing options you will actually use consistently. (Read more about wheel locks here.)

Tracking Devices

You never want to need a tracking device, but if your vehicle is stolen, having one can make a huge difference. Providing police with a GPS location can lead to faster recovery and often less damage. Do not rely solely on your HondaLink built in GPS! The vast majority of thieves that are stealing these cars already know how to disable your Honda’s tracking systems and will do so quickly. Adding in a secondary, well-hidden device (or possibly more) will make make the thieves much less likely to discover and disable your tracking capabilities. There are many tracking options available, including hardwired and battery-powered devices that use GPS, cellular, or Bluetooth technology, each with its own advantages and limitations. For the best coverage, using more than one type of tracker is often recommended. The JDI Ghost Lock tracking system is available for many late-model Honda vehicles and can even allow remote vehicle disablement. (Read more about tracking devices here)

Security Measures When Parked at Home

• Park in a garage (if you have one)-If you have a garage, parking your car inside is one of the most effective theft-prevention measures you can take at home. A garage makes your vehicle more difficult to access while also keeping it out of sight. Just make sure to keep the garage locked, consider installing an alarm system for added security, and, as always, use other anti-theft measures as well. A garage should be one layer of protection, not your entire defense.
• Use home security cameras and lighting– (View on Amazon) Increase the pressure on would-be thieves by keeping your driveway and surrounding areas well lit with motion-activated floodlights and security cameras covering your vehicle and other parts of your property. While many thieves won’t be deterred by lights and cameras alone, they still make your home a slightly less attractive target and can provide valuable evidence if a theft or break-in does occur.. (Read more about lights and cameras here)
• Block in your Honda with lower risk cars– If you have another vehicle that’s less likely to be targeted than your Honda, consider parking it behind the Honda in your driveway. This makes your Honda more difficult to access and can discourage thieves looking for an easier target. Like parking in the garage, it also reduces the risk of (or at least slows down) theft by tow truck.
• Install a driveway motion sensor– (View on Amazon) Driveway sensors can notify you if someone enters your driveway at night, giving you a chance to respond before your vehicle is stolen. (Read more about driveway motion detectors here)
• Consider installing a gate– While it can be an expensive investment, a gated property adds another layer of security by making it more difficult for thieves to access your vehicle. The added barrier and delay can make your home a less appealing target compared to easier opportunities nearby.
