10 Startups That'll Change The Smart Car Key Fob Replacement Industry For The Better

What Can a Smart Car Key Fob Do For You?

Mercedes introduced the first fobs back in 1998. They are also referred to as smart keys, keyless entry or keyless entry fobs. Key fobs that are computer controlled can perform a variety of functions, including locking and unlocking cars as well as starting it.

They work by transmitting an encrypted message that is continuously transmitted. This protects them from hackers with a technological edge.

Safety

A smart key fob constantly communicates with the vehicle using radiofrequency signals. It sends a low-power signal that, when pressed, tells the vehicle to unlock doors and start the engine. The car is programmed to recognize the unique encryption code of a specific key fob. This means that if the key fob is stolen, the car can't be started.

But a brand new type of hacking could enable thieves to gain access to that communication. Relay attacks are carried out using devices that transmit at the same frequency as a key fob. A thief can place one of these gadgets in a pocket or hiding spot to jam the lock command from a distance, according to How Stuff Works Electronics. This is a risk that may become more common as more and more drivers are switching to smart keys.

A smart key fob isn't just a security feature, but it can also make your life easier by automatically taking care of the needs of your vehicle. For smart key for cars connected to your smartphone will detect your proximity and unlock the doors, meaning you don't have to press a button on the remote. It can also detect when you're leaving the car and auto-lock the car, meaning you don't have to worry about not locking the doors. Many smart key fobs have a battery indicator that alerts you when the battery is depleted. In addition, replacing the battery on the majority of models is an easy and simple procedure that doesn't require any special tools.

Convenience

Contrary to traditional keys made of metal smart keys do not require physical insertion into an ignition slot to unlock or start a car. Instead, the driver must have it on their hands and bring it within range of the vehicle, as described by the BMW Group. Certain smart keys, such as the Display Key, feature a small LCD touchscreen that allows drivers access to features like locking, unlocking, and keyless starting directly from their key fob, without having to connect to the Bluetooth system of the car.

A smart key could also save drivers time by automating the locking of their doors when they leave. Consumer Reports says that this feature is present on a variety of vehicles. It also makes it easier for drivers to maneuver around tight spots without accidentally pushing someone or something.

Open Road Auto Group explains that smart key systems don't transmit the same frequency signal repeatedly, as this can make them more vulnerable to relay attacks. In this way a stolen vehicle can't be connected to a hotwire if equipped with a smart-key because the encrypted signal that the key fob transmits is unique to each vehicle. This technology makes it difficult for thieves steal cars.

Security

Some of the latest electronic features in today's newer vehicles are found in the key fob. These gadgets do much more than lock and unlock doors, or make chirping noises to help drivers find their car in a parking space, but some owners may not be aware of all that these smart key fobs are able to do.

For instance, some smart keys are able to activate the auto windows of a car and sunroof when they are pressed. One CR auto editor went into her Honda Accord to find the windows closed and the sunroof wide open. That's one of the reasons she was thankful for her Smart Key, which locked the car automatically.

According to How Stuff Works, some smart keys employ computer-encrypted signals to prevent car thieves from stealing. This technology stops hotwiring in which thieves steal a vehicle's engine controller module (ECM) which is typically located at the front of the engine. The ECM manages many essential functions including engine power, transmission control, and many more.

Smart keys also include anti-theft codes as well as a unique ID security code assigned to each key. This could stop ignition if the wrong key is used. The security ID is a special code that is transmitted from the ECM to the key when it's put in the ignition and checked by a sensor inside the car.

Maintenance

A smart car key fob can do more than just unlock your door. It can start your engine, and also activate suspension and brakes remotely. It can also provide details about your vehicle, such as the level of your fuel and oil temperatures.

Like any piece of electronic equipment smart car key fob needs regular maintenance to operate correctly. The majority of modern key fobs have battery indicators that warn the driver when the battery is low. It's simple to replace the battery and you don't need any special tools.

In some instances, the smart key will stop working completely. If you suspect that's the case, try to reset it by leaving the vehicle and then coming back inside. This will help the car recognize that the fob is still in use and allow it to regain functionality.

Contact a locksmith if you are not able to get your key fob to function. They can reprogram the fob to ensure that it can be recognized by your car and you are able to use all of its features. This is usually less expensive than purchasing a new key and could save you money over time. In some cases, the locksmith can fix an existing key fob in order to be able use it to purchase a new one.
