Key Fobs
Modern key fobs provide a number of convenience and security advantages. They can be used to replace or augment traditional car keys and be used to control more than simply locking doors. They can start the engine, activate the alarm, and perform other functions.
The key fob communicates to the receiver inside the vehicle by using radio signals. When you press a button on the key fob, it sends a code to the receiver, which responds by performing the desired function. Commercial building owners also use key fobs because they can integrate them into an entire system of access control. They can monitor who is allowed in or out, and they can prevent fobs that were stolen or lost.
Key fobs, just like any other electronic device, may malfunction. Because they are constantly tossed around in pockets and purses, they can become damaged or lose their signal. While they are able to take many abuses but they're not indestructible. They are made from plastic and metal.
If your key fobs stop functioning, it could be time to change the battery. Use the correct battery and refer to your owner's manual to find out how to replace it properly. Also, make sure to follow any additional steps for recalibration or reprogramming that may apply.

Modern keyless entry systems use rolling code technology to protect against hacking and other security breaches. However, it's important to keep in mind that even this technology has its limitations. Utilizing a technique known as "replay attack," a thief can use the transmitter on the key fob to send a message that is recorded by the vehicle's receiver. After the message has been recorded by the receiver, a rogue device could send the same message again to the car's receiver and gain access to the protected property.
Based on the model and make of your vehicle, you may be capable of programming new keys on your own or you may have to hire an automotive locksmith to do it. Certain car manufacturers have an onboard program specifically designed for them and others require you have a sophisticated programmer connected to the OBD2 connector.
The most commonly used method to program new car keys is to place the fob of the key in the ignition and turning it multiple times in a particular sequence. This puts the car in a "programming mode," and once it is activated, one or more fob buttons are depressed to transmit the digital identity code to the car's computer. The computer saves the code and then removes the car from programming mode.
Certain manufacturers require that you have a special advanced programmer to program key fobs. They are costly and hard to use by the average person. For this reason, it's generally best to let an automotive locksmith or dealer handle the task for you.

This will stop the system from locking your doors while you try to program the key. Then, with the ignition key along with the other keys you wish to program close by, press and hold the button on the fob you wish to activate until the danger lights flash twice.
