What You Should Know About Smart Keys

Smart keys, also referred to as digital keys or information key, allow drivers to access their vehicle without having to fiddle with traditional keyholes. Certain vehicles come with them as standard features while others allow them to be upgraded.

The technology is better than the traditional key fob as well. Certain systems have emergency start capabilities that let you open the car and start the engine without a key fob (or even a traditional one). The most effective ones also come with battery indicators which warn you ahead of time when the battery is about to run out.

Security

Smart keys are a lot more practical than traditional key fobs as they have added security and safety features. They connect to the computer system of your car by using radio-frequency identification (RFID). If the key is within range of the antenna it is able to unlock the doors and start the car without the need to use a phone or push the button.

While this may seem like a useful feature however, car thieves can hack into the system to open your doors and start the engine. Certain manufacturers employ a method called "rolling codes" that stop this from happening. This code is projected from the key to the starter and then verified by the Broken Car Key Repair's computer prior to beginning. This prevents thieves from creating multiple copies of the key.

You can also ensure your vehicle is safe by not putting your phone and the key in the same pocket. The two devices placed too close to each other could block signals, which can stop the devices from communicating correctly.

The KeySmart Pro has a built in Tile that helps you locate your phone. If you have the app installed on your iPhone and place the Smart Key near it, a press of its activation button triggers the Tile to emit an unintentional melody and flash an LED. This can be life-saving in case you've lost your phone in a dark space or even when it is in silent mode.

Convenience

In addition to locking and unlocking your car Smart keys can also store and recall personal settings such as seat, mirror and steering wheel positioning. Some, such as BMW's Comfort Access, even allow you to start your car without having to press the ignition button.

Modern smart keys communicate with the car's antennas through radio waves. They transmit an encrypted message that is then interpreted and acted upon by the computer. These signals can be modified to perform different functions like opening and closing the trunk or activating an electronic child lock.

The technology isn't completely foolproof However, it's not completely foolproof. It is possible for cybercriminals to recognize the frequency transmission of a smart car key fob key and intercept its unique identification number. Fortunately, manufacturers are striving to improve the security of the system.

One of the most useful features is that you can remotely lock and unlock your vehicle by pressing the screen of your phone. This can help you save time when loading up your kids or cargo. This can be particularly beneficial if you're a parent of teens who are just learning how to drive.

The sleek compact design of the smartkey is one of its most appealing features. This makes it much simpler to carry than other key organizers which can be heavy and take up a lot more space than is needed. KeySmart is also quiet and comfortable to carry. KeySmart is also quiet and easy to carry, removing the annoying jingle that can cause you to be irritable.

Battery Life

Typically, smart keys last half as long as regular keys with blades (two to three years, versus four to six). The smart keys have to communicate with the car smart key at a much higher frequency and more frequently to unlock and start the vehicle. Smart keys also drain faster if they are placed close to electronic devices, such as phones, computers and screens that produce electromagnetic fields.

Fortunately, the majority of smart keys have battery backup features. According to Open Road Auto Group, most come with an emergency blade that acts as a traditional key to open the driver's door in the event that the smart key fob battery fails. Most have a slot that an old-fashioned key can be placed to start the engine in the event that the smart key fob isn't functioning or is dead.

A "power saving mode" is another smart key backup. If you lose your smart key while driving, your car will still run regardless of whether it's not running. To do this, place the smart key flat on the steering column and press the ignition button. If you have done this correctly, the system will notify the driver that it's low on the key, but nonetheless functional.

Cost

Smart keys are not always inexpensive. Many owners of vehicles upgrade their keys to smart ones to enhance security and convenience. It can be expensive to replace a lost smart key and reprogram your vehicle.

Smart keys appear like normal key fobs, however they are equipped with a microchip that can be used to unlock, lock or start a car without a physical one. The chip transmits a unique code to the vehicle's system, which recognizes and validates the code prior starting the engine.

This technology has been around for a while, but isn't completely yet perfect. This technique has been used by thieves to steal cars in numerous instances. There are ways to prevent this from occurring. One option is to utilize a smart key that has security codes that roll, which alters the code each time it's transmitted.

A key fob that has an LCD screen can be extremely expensive. BMW's Display Key is an example of this type of smart key. Its LCD color touchscreen serves the usual functions of a keyfob such as locking, unlocking and keyless start but it can also transmit commands from an iPhone to the car's systems. This makes it easier to operate the vehicle smart key and keep the track of charging and location. It even allows the vehicle to park itself. This is a great feature for those with physical limitations or disabilities.
