Key Fobs
Modern key fobs come with a host of convenience and security benefits. They can replace or enhance traditional car keys and can control more than simply locking doors. They can start the engine, trigger the alarm, and perform other functions.
The key fob makes use of radio signals to communicate with a receiver installed in the vehicle. When you hit a button on the key fob, it transmits an encoded code to the receiver, which responds by performing the function you want. Key fobs are also popular with commercial building owners who can incorporate them into a larger access control system. They can track who is entering and leaving and prevent fobs from being lost or stolen.
Like any other electronic device keys can fail periodically. Because they are constantly tossed around in pockets and purses they may get damaged or lose their signal. Although they're built to withstand a lot, they are not indestructible. After all, they're nothing more than plastic and metal.
If your key fob stops functioning, it could be time to change the battery. Make sure you use the correct battery, and consult your owner's manual to learn how to replace it properly. Also, make sure to follow any additional steps to recalibration or reprogramming that may apply.

Keyless Entry
Keyless entry allows you to unlock your car and begin it without needing to insert a physical key. It utilizes a wireless signal to connect with the car's internal system, and it can also allow you to control different functions in the vehicle including climate controls or music systems.
Modern keyless entry systems utilize rolling code technology to protect against security breaches. It's important to note that even this technology isn't completely secure. A thief could use a technique known as "replay attack" to transmit a message that is recorded by the receiver of the car. After the message is recorded, a malicious device can retransmit this transmission to the vehicle's receiver and gain access.
Depending on your vehicle's make and model it could be possible to program new keys on your own or you may have to have an auto locksmith assist you. Some car companies have a special onboard programming process and others require an advanced programmer connected to the OBD2 port.
The most common method to program new keys for cars is to insert the key fob into the ignition and then turn it on in a specific order. When the car is placed in "programming mode," one or more buttons on the fob are pressed to send the digital identification code to the computer. The computer stores the code and then removes the car from programming mode.
Certain manufacturers require you to have a special advanced programer to program key fobs. They are costly and difficult to use by the typical person. For this reason, it's generally best to let a professional locksmith or dealer do the work for you.
