What is the difference between car key and key fob?

Car owners used simple metal keys to lock and unlock their cars in the past. It was not the best way to secure the car but it was all there was. These days, such keys are replaced by more secure keys, transponder chips, and remote control key fobs.

A key fob is a small electronic device with buttons that make car usage much more convenient and you can even say, it is a lot more fun. Keyless entry systems use key fobs for locking and unlocking doors from a distance. Besides being extremely convenient especially when your hands are full when you need to lock and unlock the doors. A key fob is also used to control a car’s trunk and windows. Some Fobs allow you to start the engine remotely and even allow you to activate a panic alarm, should if ever become necessary. A key fobs receiver and transmitter are synchronized so nobody else’s key fob will work with your car. This is because remote keyless entry systems will only allow access with the specific fob.

This relatively new locking system has become the best security method for cars, as it offers high-level security against thieves.

Key fob offers a lot of convenience for its user. You can lock or unlock the car just by pressing a button. All you need to do is have a key fob with you, and the car will know when you are nearby. Another advantage is that the car will automatically lock itself after you have walked a certain distance away. However, if the key fob doesn’t work, the car owner can use the metal car key that sits inside the fob, as a backup method, to lock or unlock the vehicle this will also prevent the alarm from sounding.

Each key fob has its own unique code, so the hazard of theft is low giving a strong sense of security to the car owner.

Key fobs need to be programmed so if you need to replace a key fob you must use a professional locksmith. Of course, Sure Lock & Key has the relevant knowledge and experience to help you.

The benefit of a car key is that it is simple and relatively reliable. The key is made of durable material. With proper care, it will last for years. One more benefit is that there are no batteries to replace.

They certainly are not as convenient as key fobs. You need to lock or unlock the door manually. It is especially uncomfortable in cold weather or when you are in a rush. Also, the lock and key can deteriorate over time. The biggest difference is security. When leaving one's car most people will lock their car but will not check to see if all the doors and windows as well as the trunk are shut. This is because it’s a real big inconvenience. However, with a key fob one quick use of the button, on the key fob and everything is closed.
