All About Car Smart Key
A car smart key uses technology to assist you in starting your engine, managing the locks on your car, or performing other functions. Smart keys communicate with your car through antennas installed within it. It receives and sends signals, which are interpreted by the vehicle’s electronic computer. After understanding the message, the car computer sends a command to ensure the specific function is carried out. Initially, smart keys were only limited to opening car trunks or locks. Now, they can also turn on the ignition system of a car or disengage its immobilizer.
How a Car Smart Key Works
Unlike traditional car keys, the smart car key doesn’t need whoever is driving to bring out the key fob from their pocket. Once it’s connected to an antenna in a car, the control unit sends out a radio pulse with instructions to activate the ignition or unlock the vehicle.
Modern smart keys can also be used to adjust other car settings like steering wheel adjustment, driver’s seat position and stereo presets once inside the car. Some smart keys can also be used to prevent cars from going over a set speed limit. This is very helpful if you’re giving your car to an inexperienced driver, as it helps to minimize the risk of car accidents.
What Are The Security Requirements For Vehicle Smart Key Systems?
Using smart keys offers a convenient method of car ownership. Still, it can be quite dangerous when it’s not protected or utilized properly. For example, if a car picks up the low-frequency transmission from a smart key when the owner is far from it, a stranger could get into the car or even start and drive it. To avoid this, the maximum frequency field for your car’s smart key system should be 10 cm. Fortunately, a smart key doesn’t send a particular frequency signal repeatedly. As a result, it makes the system protected from tech-savvy thieves.
Does A Smart Key Have Battery Backup?
Yeah, smart keys use batteries that can become depleted. In fact, some smart key systems are even designed to inform their users that the battery is low. Moreover, most smart key systems have additional ways to lock, unlock or start a vehicle when the battery’s low. Additionally, emergency starting can be done by holding the key near a special area in the cockpit or placing it in the slot. The procedure is called inductive coupling.
Benefits Of Using Car Smart Keys
Convenience
One of the major advantages of using a smart key is convenience. Since its discovery, there has been a deduction in the number of drivers that fumble with keys, especially in the dark.
Reduce Ignition Worries
A conventional car key will automatically wear out after a while. Besides, these keys are heavy, so carrying them around can be stressful. This is because most people combine their house and car keys.
Emergency
When you’re in a state of emergency, trying to get your keys out of your pocket can waste and put you at more risk. With a smart key stream, the door unlocks automatically. All you have to do is get inside and zoom off. This has saved a lot of people from difficult situations.
Given the benefits of car smart keys explained above, don’t hesitate to contact a good automobile service provider to see if your car can be equipped with one. If your car is too old to get one, you can use that avenue to upgrade the car to a newer version that supports a smart key or get a new car that has a smart key feature installed directly by the manufacturer.
