How Far Can You Drive Without Key Fob?
Driving a car without inserting the key is not a big deal anymore. It is not necessary to insert an appropriate key to start the ignition. The matchbox-sized gadget does all the tricks these days. You can easily lock, unlock, or start your car without inserting the key. Driving the car with the key still in your pocket is trouble-free.
But the question is how far can a keyless car drive without the key? The answer to this question lies inside your fuel tank. The car will not stop until it runs out of fuel. No matter how far you go or want to go. It will be impossible to start the vehicle once you turn the ignition OFF.
The process may vary in different vehicles with different technology. Some key fobs do not let you cross the zone unless you have them inside the cabin only. It all depends upon the proximity of the key fob to the vehicle.
Additionally, the exact answer depends on the make and model of your vehicle. You can drive a short distance without using a key fob in some cars (some key jobs can operate more than 30 to 50 feet), and if you expect to drive farther than that, you have to use your key.
Normally, drivers can continue driving until they turn off the ignition system. But other models can’t start or shut down automatically without a key fob. Ideally, you should always have this key with you while driving a car to prevent any unwanted issues.
However, don’t worry! With the developed technology, some modern cars have been equipped with a system that will give you a warning when your key fob is out of range so that you can come back and take it before driving too far away.

How Does a Key Fob Connect & Work? The Explanation
Key fobs are a vital part of vehicles nowadays. These are some of the best gadgets in an automobile. One must use the fob wisely, with proper attention and care. A key fob is nothing but a transmitter with a unique ID.
It has a battery and tag number matching that of your vehicle. It sends signals to the vehicle for locking, unlocking, or starting the car. The key can only operate within the set range and not more than that. The receivers of the car antenna transmit these signals and control your commands appropriately.
Some cars notify you about the key fob while you drive. You might not notice the signals and beeps coming from the car. The situation might lead to serious troubles sometimes.
According to expert driving tips, it is imperative to check your key fob before starting your ride. One can place it inside the cup holder, pocket, ignition, or anywhere inside the car.

Some Notes When Using A Key Fob
Drivers also need to master the following notes to use a key fob more effectively:
- Do not use a key fob when the battery of the key is low or near TV towers, radio stations, airports, or devices with strong radio waves.
- Shouldn’t put the key together with wirelessly linked devices, smartphones, or laptops.
- Do not place metal objects on the FOB handheld.
- Avoid storing the FOB controller in a place subject to high temperature, humidity, or strong magnetic fields.
- Read the manufacturer’s manual carefully to perform the correct operation of starting the car with the smart key.
