A key fob, or car remote, is an electronic device that allows cars to be opened and locked without a key. It typically has buttons for unlocking doors and opening the trunk. A key fob is a small keyless entry system that uses a low-frequency, short-range radio transmitter to send a signal to the receiver inside the car. Some fobs can even be used to start the car. In addition to locking and unlocking doors, and starting the engine, a fob can perform other tasks. Some of the buttons on the fob may be dual functional and pressing them more than once or holding them down for longer will activate a different function.
Everything to Know About Your Car’s Key Fob
Wing Mirrors
Unless your car automatically senses a risk to side-view mirrors and folds them in, a car key fob now has a button for this too. Those who shop at busy shopping malls will appreciate the benefit of folding in the wing mirrors. This can help to prevent damage by laden shoppers trying to squeeze past or by other vehicles struggling to park beside your vehicle.
Seat Adjustment Memory
It is rather annoying to climb into the driver’s seat after your tall, lanky, or small teenager has been behind the wheel. A key fob comes with its own unique number and therefore knows who the driver is. Once you have set the position of the seat and set the car’s memory, the fob will be able to return the seat in accordance with your preferences.
Radio Memory
Just as with memory seats, a fob can return your radio to your favorite radio stations after the kids have left the radio on a head-banging station. The radio memory inside the key fob will restore sanity instantly.
Car Summoning
Some of the newest cars have a function on the key fob that allows the car to move when the driver is not inside. To activate this feature, enable the summon function on the control panel on the dashboard. The fob will then be able to engage the car to move forward or backward. This is a very nifty function when parked in a tight bay and you are unable to open the door.
Lost Car Keys
Perhaps the most practical function of a fob is that you can track it from a mobile phone. However, you must install the application on your smartphone before synchronizing it with the fob. If you are in the vicinity of the lost fob and you call it, some key fobs will emit an alarm long enough for you to find it. This feature can be a lifesaver in the worst of handbags or a busy parking lot.
Key Fob Range
These days, car thieves are very clever at blocking remote signals sent from the fob to the car from a distance. One solution to this is to extend the range of your fob. To do so, hold the key fob against your chin. Then, by pushing the lock, unlock, or panic button, the key fob range will expand. Test the range by increasing your distance from the car to see how far away the key fob will work. It may sound like science fiction or an April fool’s joke, but give it a try.
Windows and Sunroof
A generic feature of a modern-day automotive key fob is that it can open and close windows as well as the trunk and sunroof.
