Car Key Vs Key Fob - What's The Difference?


You may not have thought much about the difference between a car key and a key fob before, but the difference can be a crucial one. Everyone wants to make sure their car is as secure as can be, and the right key is essential for making it as difficult to steal as possible.

What's The Difference?


First, it's important to understand the difference. The car key is the metal part that slides into the barrel of the lock. The key fob is usually made of plastic and is joined to the top of the key. On newer cars, the key can be integrated into the fob and swing-out at the press of a button, and many "keyless" cars don't even require a physical key at all.

What Are The Benefits Of Both?


The benefit of a mechanical key is that it's relatively simple and reliable. Metal is a durable material, and a well-cut key that's properly taken care of will last for years. There are no batteries or technology to replace. It's also much harder for car thieves to steal or clone mechanical key than to boost a signal from a smart key fob.

The benefit of a key fob is that it offers complete convenience. At the touch of a button, you can lock and unlock the car, unlock and maybe even open the boot, and if you have a smart key system,it can even mean the car can be started. All you have to do is have the key on your person, and the car knows when you're nearby.

What About The Disadvantages?


The disadvantage of mechanical keys is that they're not as convenient as smart key fobs. Also, it's possible for lock barrels to wear smooth over time, and for mechanical keys to become damaged.

The disadvantage of smart keys and fobs is that because they're so much more complicated, there's a much higher risk of something going wrong. They can also be more expensive to replace and will need to be reprogrammed.

The Major Disadvantage Of Smart Keys


The primary disadvantage of smart keys is that they can make it easier to steal cars. Thieves use a device called a signal booster to amplify the smart key signal, which can then unlock and start the car.
