What is a key fob, anyway?

A key fob is a small remote device that allows you to control a keyless system. With a key fob, you don't need an actual key to get into your car. The key fob uses radio frequencies to communicate with your car and control it. The jingling of keys becomes a sound of the past if you have this handy device (you shouldn't attach any other keys to your ignition key, anyways.)

Turns out, there's a lot you can do with this convenient piece of technology. Here are some secret uses for your car key fob that you may not have known before—try them out for yourself!

Start your car remotely with your key fob

In some cars, your car key fob can remote start your vehicle during chilly days, depending on whether or not idling is legal in your state. Just look for the remote engine start button often labeled with a circular arrow, Consumer Reports says.

Use your fob to lower your windows

Did you know you can also use your key fob to catch a breeze? HuffPost reports the key fob for many cars now can roll down all windows at once. Try pressing your unlock button twice, holding down the second time until all windows are open. Speaking of car windows—have you ever wondered why they have those black dots on them?

Fold in your mirrors with your key fob

If you've maneuvered your car into a tight parking space, your key fob can help make sure your side-view mirrors don't get knocked off when someone else is squeezing by. For cars that don't do this automatically when they lock, try holding the key fob lock button for ten seconds. Consumer Reports says this feature tends to be available on newer Chevrolet and GMC pickup trucks. Here are some other weird car features you may not have known you have.

Unlock your trunk with your fob

In older cars, you may have had to use a mechanical key to get back in the trunk, but now many newer models have key fobs that allow you to open your back hatch with just the click of a button. Nervous about locking your keys in your car? Here's how to unlock a car door without your keys (just in case).

Start your car with your key fob

Keyless ignition systems are becoming more common, with 62 percent of cars sold last year having this feature, Edmunds reports. Should you choose to go keyless on your next model, your fob can serve as a way to start or stop your car as long as the fob is in the car with you and your foot is on the brake. Just make sure to never leave your key fob in your car (but you can leave these items in there).

Use your fob to stay safe at night

The key fob of almost every car has a "panic" button which will set off your emergency alert systems, helping you find your vehicle in the most crowded parking garage. But if the garage is deserted, setting off this feature can also help ward off would-be criminals, says RepairPal. Here are some new car safety features no vehicle should be without.

Prevent home break-ins with your key fob

The attention-grabbing blare of your car's alarm system can also prevent home break-ins. If your key fob works on your car from within your home, keep it by your nightstand, says RepairPal. If you hear something in the night, hitting the panic button can scare off criminals and is one of several things you can do to save your home from a break-in.

Use the fob to unlock your car

OK, this one may seem obvious… unless you have a keyless car and a fob with a dead battery. As keyless ignitions become more popular, fewer and fewer cars operate with traditional mechanical keys. The problem here? The fob that unlocks the car by sending computer signals to the vehicle can run out of batteries. Luckily, Toyota says the fobs for its keyless cars also have a mechanical key tucked in them should this be the case. Good to know, especially if you need to get something you shouldn't have left in your car.

Adjust your seat with your fob

Sharing your car with a gentle giant or someone whose legs just don't have the same reach as yours? GMC offers some models that allow you to set a "memory" of where you like your seat. Each key fob is assigned a different number, so when you get in the car, it knows who's driving. From there, you can set your seat preference and go. By the way, bookmark these car maintenance tips that will extend the life of your vehicle—they're so helpful!

Use the fob to park in tight spaces

Never again worry about scraping another vehicle. The car key fob for Teslas can be used to park your car in tight spaces, says Business Insider. The driver doesn't even need to be inside. The "summon" feature will stop when obstacles are detected and even close your garage door for you. How's that for a car accessory that'll change the way you drive?
