Programming car key fobs can be completed in various ways, depending on the make and model of your vehicle. In many cases, you may need to enlist the services of an automotive locksmith to ensure you have the correct type of key fob for your particular car before attempting to program it.

In this article, our team at Car Key Rescue will explain why more vehicle manufacturers are choosing car key fobs over traditional keys, how car key fobs work to unlock and start a car, and how an automotive locksmith can program a new key fob to a car. With this information, you will be better prepared in case you ever need to program a new key fob for your vehicle.

Why are More Vehicle Manufacturers Choosing Car Key Fobs Over Traditional Keys?

Car key fobs, also known as keyless entry remotes, have become increasingly popular in recent years among vehicle manufacturers. These small devices allow drivers to unlock and start their cars without the need for a traditional key.

One of the main reasons for this shift is the added convenience and security that car key fobs provide. With a traditional key, it is possible to duplicate it without the owner’s knowledge, whereas, with a key fob, the code must be programmed specifically for that vehicle, making it much more difficult for a thief to gain access to the car.

Another advantage of car key fobs is the ability to remotely start the car, allowing the driver to warm up the vehicle in cold weather or cool it down on hot days, without having to physically be in the car.

How Do Car Key Fobs Work to Unlock & Start a Car?

Car key fobs work by sending a radio frequency (RF) signal to the car’s receiver, which is located near the ignition. When the button on the fob is pressed, it sends a unique code to the car’s receiver, telling it to unlock the doors or start the engine.

The RF signal is transmitted at a specific frequency, typically 315 MHz or 433 MHz, and is picked up by the car’s receiver. The receiver then decodes the signal and compares it to the codes programmed into the car’s computer. If the code matches, the doors will unlock, or the engine will start without ever having to insert a key.

How Does an Automotive Locksmith Program a New Key Fob to a Car?

An automotive locksmith is the best person to contact when it comes to programming new car key fobs. They will have access to the tools and knowledge needed to successfully program your new car key fob, as well as be able to test the signal strength and range of the device in order for it to work properly with your vehicle.

Programming a new key fob to a car typically involves connecting a diagnostic tool to the car’s computer and inputting a series of codes. The process usually takes around 30 minutes to an hour, and the cost will vary depending on the make and model of your vehicle.
