An Introduction To Advanced Key Fobs
We live in an era that promotes progressive convenience. That is, society is deeply interested in a never-ending pursuit to make our lives more convenient. In the past 20 years, that pursuit has led to the invention of the television remote, gas pumps that accepts credit cards, and even drive-thru coffee shops. In the automotive world, key fobs that allow you to crank your car’s engine without sticking the key in the ignition are becoming commonplace.
Today, I’ll describe how they work. I’ll also explain the safety features that are built into the system in order to prevent mistakes and reduce incidents of theft.
How They Work
When you approach your vehicle, a sensor that is built within identifies the key fob. The two devices share information in order to authenticate your identity. Once you’ve been identified, your driver’s door will unlock, allowing you entry, even if the key fob is in your pocket or purse. Once you’re in the driver’s seat, you’ll be able to start the engine by simply pressing a button on the ignition.
All key fobs rely upon batteries for their power. As you can imagine, that leads a lot of people to ask, “What happens when the battery dies? Will I be locked out of my car?” If the battery within the unit dies, it will continue to share information with your car. That means you’ll still be able to gain entry and start the engine.
Averting Common Problems
Some of the common mistakes that have plagued drivers for years include locking themselves out of their vehicles and unwittingly locking their keys within. With these advanced devices, there’s little chance of that happening. The sensors built within your car can detect the presence of the device. Specifically, if the system identifies that the remote device is within the vehicle (including the trunk), it will keep the locks disengaged, allowing you access.
The 2 Main Benefits
You might be tempted to rationalize why you “need” a system that lets you to unlock your car doors and start the engine while your keys remain in your pocket or purse. In the end, it’s mostly about convenience and theft prevention. For example, reaching into your pocket to grab your keys may be inconvenient, especially if you’re carrying other items. Meanwhile, thieves who lack the remote device required to gain entry and “push button” start the engine are left with no opportunity to steal your vehicle.
These systems aren’t widespread at the time of this writing. However, given society’s continual trend toward convenience, that’s likely to change. Over the next few years, automakers will begin producing larger portions of their fleets with advanced key fob options.
