Self-Programming
In the years leading up to the 21st century, key technology began to move away from simple mechanical keys to an amalgamation of physical and electronic protocols to stop theft. These new keys are equipped with a microchip which must be programmed to connect to the vehicle's electronic system. The best method to change the programming of your car keys is with an experienced locksmith who has access to the appropriate equipment. Many vehicles, particularly high-end ones, allow only dealers to create new keys.
If you're looking to try this yourself, the procedure is different for each manufacturer. In general, you will need to place the spare key into the ignition and then manipulate it (according to the directions in the owner's manual) until your car enters the programming mode. This only lasts for just a few seconds before your car leaves the programming mode.
Once your vehicle is in programming mode, you will have to repeat the procedure for each key that you'd like to program. The instructions contained in the owner's manual are specific to the key type and model you are trying to program, as certain models come with additional security features that have to be enabled (for instance, a passcode that is required to enter certain programming modes).
Certain models also require a code that you can only obtain from the dealer for a fee. This code helps protect against "skimming" which happens when a thief attempts to read your key's information through the OBD2 port to start the car and steal it.
This is a great way to save money on a replacement car key, however it is crucial to know that if your key isn't properly programmed it won't be able to unlock or start the car. J.C.

Key Programmers
If you've lost your car keys or if you're replacing them, you might wonder whether it's possible to reprogram your key. It depends on the manufacturer, but most cars require that you work with an auto locksmith or dealer to have the new key programmed into the vehicle's system. This requires reprogramming the new key's transponder to match the settings of the original car.
While some vehicles allow you to do this yourself, most require a professional or dealer to use a specific tool that is able to connect with the vehicle and read the programming data from the ECU. Then, the key is modified to match the car's settings and you can begin using it as a normal key.
There are many types of car key programmers. Certain are designed specifically for specific models and makes, while others are universal and work with a wide variety of vehicles. The majority of these devices come with a small display and several buttons that you press to enter the programming mode. You can plug the device into an OBD-II connector to start reading and program the new key.
It takes only a few minutes for professionals to program a new lock in the majority of cars, but certain cars may take longer and require complex procedures to reprogram keys correctly. For instance, certain modern vehicles require a specific code that only the car dealer is able to access and use to access the immobilizer's system. In these instances you should delegate the job to professionals to avoid damaging the system and resulting in a non-existent way to start the car.

Key Fobs
Modern key fobs offer a number of convenience and security advantages. They replace or supplement traditional car keys and manage more than just locking doors; they can start the engine, activate the alarm and perform various other functions.
The key fob communicates to the receiver in the vehicle via radio signals. When you hit a button on the key fob, it will send an encoded code to the receiver, which responds by performing the desired function. Commercial building owners also make use of key fobs because they can integrate them with an entire system of access control. They can monitor who enters and exits, and also prevent fobs that were taken or lost.
As with any other electronic device key fobs are susceptible to failure periodically. They can break or lose their signal when they are placed in purses and pockets. Although they can withstand a lot of abuse however, they're not impervious to damage. They are made from plastic and metal.
If your key fobs stop working, it may be time to change the battery. Make sure you use the correct battery, and refer to the owner's manual for directions on how to replace it correctly. Also, ensure that you follow any additional steps for reprogramming or recalibration that might apply.
Another common cause of failed fobs is wear and tear. As they are continually being thrown around, smashed into objects, and jostled about in purses and pockets, they can become worn down or even damaged. A simple and inexpensive fix is often all you need to make your key fobs work again.

Keyless Entry
Keyless entry allows you to unlock your car and start it without having to insert a physical key. It uses radio signals to communicate with your car's internal system. You can also control other features, like the climate control or music system.
Modern keyless entry systems employ rolling code technology to protect against security breaches. It's important to note that even this technology is not completely secure. Utilizing a technique known as "replay attack," thieves can use the transmitter on the key fob to transmit a message that is recorded by the vehicle's receiver. Once the message is recorded by the receiver, a rogue device could send the same message again to the car's receiver and gain access to the secured property.
Based on the model and make of your vehicle, you may be able to program new keys on your own or you may have to hire an automotive locksmith to complete the task. Some 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 by putting the key fob into the ignition and engaging it several times in a specific order. This puts the car into the "programming mode," and once it is activated, one or more fob buttons will be pressed to transmit the digital identity code to the car's computer. The computer then saves the code and takes the car out of programming mode.
Certain manufacturers require a special advanced programmer to program key fobs and some of them are expensive and difficult to use for a common person. Therefore, it's best to let a professional locksmith or dealer do the job for you.
To set up the keyless entry system begin by stepping into your vehicle from the driver's side and close ALL the doors except the driver's. This will stop the system from locking the doors while trying to program the key. Push and hold the button of the fob you wish to activate when the ignition is turned on and the other keys you want to program are nearby. The hazard light will flash twice.
