In most modern vehicles, traditional car keys have become a thing of the past, replaced by keyless entry key fobs. The switch is due largely to the fact that key fobs offer additional convenient features. For instance, car key fobs can include abilities like opening your trunk, sounding your alarm, unlocking and locking doors remotely and even starting your vehicle remotely—a feature you might be happy to have when you need to warm up the car in winter.
Like dash cams and backup cameras, key fobs can also increase the security of your vehicle. Since modern vehicles with a push-button start are designed to sense whether or not the key fob is inside the car, the car can also prevent you from accidentally locking your keys in the car.
When choosing a new or replacement key fob, you will want to identify the specific features you anticipate needing. Don’t forget that you may want a spare car key fob if you share your vehicle.
