One such feature offered by modern car keys is locating your car in a parking lot. If you misplace your vehicle in an ample parking space, you merely need to press a button on your key. Your car will then alert you to its location by honking. This proves particularly useful in winter when distinguishing your car from a sea of snow-covered vehicles can be challenging.

Another convenient feature is the ability to remotely open and close all windows in the car. This is handy during the hot summer months when your car is parked under the scorching sun, and you need to cool the inside quickly. Simply holding the door opening button will roll down the windows, allowing the cabin to ventilate. Similarly, to ensure all windows are securely shut, you only need to hold down the car locking button.

Some car keys offer a panic mode feature. In emergencies, this function can trigger a loud alarm from the car, inevitably catching the attention of passersby.

Another intriguing feature allows the disabling of the keyless system. Some car models, including specific makes of Mercedes, permit this with a double press on the vehicle lock button. This function ensures that the vehicle won't respond to triggers like a cat scampering under the bumper, which typically causes the trunk to open. It also functions as a safety feature against thieves who could exploit vulnerabilities in the keyless system.

However, it's important to note that even the most modern cars can encounter difficulties. Hence, traditional blades are tactically hidden in keys as a failsafe for opening the car in instances of the key battery failing.

Some manufacturers, such as BMW and Hyundai, provide the ability to maneuver the car using an electric motor. While this could be useful in tightly packed parking spaces, it is generally considered an unnecessary luxury.
