How to Block LoJack on a Car

LoJack is a stolen vehicle recovery system installed in your car. When police report a car stolen, they send a silent radio signal that activates the hidden LoJack unit in the vehicle. Once on, the LoJack device sends out short radio pulses on its frequency so equipped police cars or helicopters can follow the trail. Because LoJack uses wireless radio, it works even if the vehicle is in a garage or underground parking. It does not rely on GPS satellites. LoJack runs on a special radio band set aside by regulators for stolen car recovery. That band is around 173.075 MHz.

Since LoJack uses radio signals, you can block it by using a radio jammer. A jammer works by blasting noise on the LoJack frequency, raising the overall “static” so high that police equipment can’t hear the LoJack pulses. Think of it like turning up the static on a radio station: when the static is louder than the station’s song, the station’s music can’t be heard. In this guide, we explain how to use a signal jammer to block LoJack signals from reaching trackers.

What is Lojack and how does it work?

Lojack is a device that car owners or companies install in vehicles for safety. It sends out signals to help find your car if it is stolen. The system uses radio waves to tell where your car is.

The tracking device hidden inside the car sends a signal to a receiver if the car is reported stolen. The receiver tracks this signal and tells the police where to go. This makes it easier to find the car and catch the thief.

Why You Might Want to Block LoJack

There are several reasons why a person might want to stop Lojack signals from working:

• Privacy: Some people feel uncomfortable about being tracked.
• Control: The owner may want full control of their car without outside tracking.
• Selling the Car: The new owner might want to remove tracking devices.
• Avoid False Alarms: Sometimes Lojack can give false alerts.

No matter your reason, if you want to block Lojack, you need to understand how to do it safely and effectively.

How LoJack Signals Can Be Jammed

A key fact is that LoJack transmits at about 173 MHz. To stop it, you need a jammer that covers that band. Many jammers list the frequencies they block. For example, one portable jammer specification shows LOJACK: 167–173 MHz, exactly covering the LoJack channel. When you turn on such a jammer, it floods 173 MHz with strong noise.

Because the jammer’s signal is much stronger, the much weaker LoJack pulses can no longer be picked out by police radios. In practice, this means police receivers will just hear loud static on 173 MHz and lose your LoJack signal entirely.

How to Choose the Right Jammer

These are some factors when shopping for a LoJack jammer:

Frequency coverage (MHz):

The jammer should have the LoJack channel (approximately 173). Look at the specs; there should be an explicit mention of the LoJack band.

Output power (watts):

The higher the output power, the bigger the jamming. A 1-3-watt jammer is usually sufficient for a car.

Antenna:

This can increase the distance from an outside antenna. Some jammers have one or more antennas that may be removed.

Battery:

When it is a portable device, you will have to know how long it can last. As an example, a jammer may draw enough power with a 3,200mAh battery to cover approximately 1 hour.

Portability:

There is a portable jammer that can be carried in the car or a compact one. Bigger desktop versions may not be necessary for personal use in a vehicle.

Make sure that the product covers the LoJack. Some products cover 167-173 MHz and have a specification of 20 meters of interference. On a regular vehicle, a few meters can suffice to cover the entire interior.

Step-by-Step Guide on How to Block Lojack Using a Signal Jammer

Blocking the LoJack in a car is extremely difficult. Nevertheless, with several evident steps, you will be able to make it work. The most effective method of preventing Lojack from tracking your car is by using a signal jammer. Below is a step-by-step process to help you block Lojack signals safely.

Step 1: Find Where the Lojack Device Is Installed

The first thing you need to do before blocking Lojack is to locate the device inside your car. Lojack devices are often hidden so that thieves or others cannot easily find or remove them. They tend to be placed in spots that are hard to see or reach.

Common places include:

• Under the dashboard, near the driver’s seat or the passenger side
• Inside bumpers, usually at the back of the car
• Near the engine, under the hood
• Underneath the seats or the floor carpet

To find out the exact location, you can look online for guides made by other car owners. Many forums and websites also share information about common locations for Lojack devices in different car models. Taking time to find the device will help you block the signals better.

Step 2: Select an Appropriate Signal Jammer

Select a jammer that prevents the correct Lojack frequency. Most of the jammers cover a variety of frequencies, such as those employed by GPS and radio tracking gadgets.

Step 3: Test Your Signal Jammer close to Lojack

Power on the jammer about the possible source of the equipment. Use an app or a device that has tracking capabilities to determine whether the device ceases sending signals.

Step 4: Place the Jammer Correctly

After testing, put the signal jammer in the best spot inside your car. The jammer must be close to the Lojack device to block the signals correctly. If it is too far away, the jammer’s signal may not reach the tracker.

Good placement ideas include:

• Under the dashboard near where the device is
• Inside the glove box, if it’s close enough
• Near the area where the bumper or engine is, if accessible

make sure the jammer is fixed so it will not fall or get damaged while you drive. Also, keep it in a spot that doesn’t block your driving view or comfort.

Step 5: Keep the Jammer Running When You Need Insurance Against Tracking

To prevent the Lojack, leave the jammer on as you drive or park. You can switch it off when you do not want to jam, particularly in situations where you may be at risk of being monitored. This could be during sensitive trips or when you feel like your privacy is compromised.

The aim of keeping the jammer running is to protect oneself from being tracked while being mindful of when it’s appropriate to turn it off for normal use.

Don’t wait to secure your ride; get your signal jammer from H&G Jammer and stop unwanted signals.

Things to Consider

When you are planning to have your car equipped with a signal jammer to block the LoJack, it is good to remember these few essential details. In so doing, you will be able to operate the jammer without creating any complications for other gadgets or yourself.

Other Signals

A LoJack-specific jammer operates at the frequency of 173 MHz. This implies that it blocks signals of LoJack only. It will not make them cease to operate because of a pure LoJack jammer, as your cell phone and GPS are running on very different frequencies.

But there are also jammers like GPS Jammers that block other frequency bands. This may interfere with devices such as your phone, GPS tracker, or radio, provided the frequencies are shared. Be sure to check what frequencies a jammer covers before you purchase one or even use it.

When the jammer blocks more bands, it can prevent the phone from ringing or using GPS. Don’t use jammers that do this unless you want to, by design, block all signals.

Coverage Area of the Jammer

Depending on its strength and location of use, a jammer can create a blocked area based on the type of signal that can be blocked.

A jammer typically provides good coverage of the entire interior of a typical car. This means that LoJack in your vehicle would not be transmitting signals anywhere in the interior.

The range of the jammer may decrease slightly when travelling in a larger automobile, such as a van or SUV, or when your car windows are tightly closed. Thick windows or metal can also prevent signals from radiating out as much.

No doubt, the majority of jammer devices to be used in cars are effective enough to block the whole area where the LoJack gadget could broadcast its calls. In case you require more coverage, you can check out jammers of higher power.

Heat and Noise by Operating a Jammer

A jammer requires power, which can get hot when in operation. Certain jammers are equipped with small fans to be cool, whereas others only take the air available in their surroundings.

If your jammer lying flat on a non-flammable surface then nsure that it is not placed or covered by fabrics or any type or form of paper or other things, including its vents and fans. This serves to prevent overheating.

Moreover, some jammers rattle slightly during the cooling fan’s operation. This is often low, not too distracting noise, but at least you know what you are dealing with before you purchase one.

Jammer Battery Life

Consider the working time that your jammer can withstand on a single charge.

In case of dropping battery life while driving or even parking, the LoJack device will alert you immediately. To avoid this, you should charge your jammer to the full before any journey.

Assuming that your jammer can plug into the power outlet in your car, keep the jammer plugged in during travel. That way, you will not have to be concerned about it dying on you at the least opportune moment.

Checking for Interference with Other Devices

Other radios or electronic devices using the same frequency range as a signal jammer can jam LoJack, if you use such tools.

At 173 MHz, it is primarily occupied by LoJack and some vintage tracking devices. Most newer devices, such as cell phones or Bluetooth, operate on vastly different frequencies, so they are non-interfering.

When you employ special radio equipment or some other kind of tracker in your car, it is best to test your jammer to ensure it does not interfere with them.
