Self-Programming
In the years prior to the 21st Century the technology for car keys began to evolve away from mechanical keys to an amalgamation of physical and electronic protocols to guard against theft. Many of these new keys are equipped with a microchip within them that must be programmed to link it to your vehicle's electronics system. Professional locksmiths with the right equipment can reprogram your keys. A lot of vehicles, especially luxurious ones, will only allow dealers to make new keys.
If you'd like to try this yourself, the process is different for each manufacturer. In general, you will have to insert the spare key in the ignition and turn it (according to the instructions in the owner's manual) until the car enters programming mode. You will need to move quickly, as this only lasts a few seconds before your car exits the mode.
When your car is in programming mode, you'll have to repeat the procedure for each key you'd like to program. Your owner's guide should include specific instructions for the particular model and type of key you wish to program. Certain models come with extra security features that need to be activated.
Certain models of vehicles require an additional code that can only be obtained from the dealership for a fee to you. This code protects against "skimming" which occurs when thieves try to read the information on your keys through the OBD2 ports in order to steal the vehicle.

Key Programmers
You might wonder if it's possible for you to reprogram your keys in case you've lost them or are replacing them. It is dependent on the car manufacturer, but in most instances you'll need work with an auto locksmith or dealer to program the new key into the vehicle. This process involves reprogramming the transponder in the new key to match the initial settings of your car.
Certain cars let you do it yourself, however the majority require a professional or dealer to use a tool that can connect to the vehicle and read programming data from the ECU. The key is then reprogrammed so that it matches the car's settings and you can use it as a regular key.
There are numerous kinds of car key programmers. Some are specific to specific models and makes while others are universal and work with a wide variety of vehicles. Most of these tools feature an LCD display with a few buttons to enter programming modes. After that, you plug the device into the OBD-II port to begin reading and programming the new key.
It takes only a few minutes for professionals to program a new key for most vehicles, though certain cars may require longer and more complicated procedures to reprogram the keys correctly. For example, some modern vehicles require a specific code that only the car dealer is able to access and use to read the immobilizer's system. In these instances it is best to leave the task to professionals in order to ensure that the system is not damaged and not having a method to start your car.

Key Fobs
Modern key fobs offer many conveniences and security benefits. They can be used to replace or augment traditional keys for cars 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 utilizes radio signals to communicate with a receiver that is installed in the vehicle. When you press the button on the keyfob, it sends the code to the receiver, which in turn fulfills the function you desire. Key fobs are also popular with commercial building owners, who can integrate them into the larger access control system. They can monitor who is allowed in or out, and block fobs which have been stolen or lost.
Key fobs, like any electronic device, can malfunction. They can break or lose their signal if they are jostled in pockets and purses. Even though they're designed to be able to withstand some punishment, they're not indestructible. After all, they're nothing more than plastic and metal.
If your key fobs stop functioning, it could be time to change the battery. Make sure you use the correct battery, and refer to your owner's manual to learn how to replace it correctly. Also, be G28 to follow any additional steps for recalibration or reprogramming that may apply.
Another reason for failed fobs is wear and tear. They may break or wear out if they are dropped, bumped against things and tossed around in purses and pockets. Often an easy and affordable fix is all that is required to get your key fobs back functioning.

Keyless Entry
Keyless entry allows you to unlock and start your car without having to insert a physical key. It utilizes a wireless signal to communicate with the car's internal system and it can also allow you to control different features within the vehicle, such as climate controls or music systems.
Modern keyless entry systems use rolling code technology to safeguard against security breaches. However, it's important to keep in mind that even this technology has its limitations. A thief could use a technique referred to as "replay attack" to transmit a message that is recorded by the receiver of the car. After the message has been recorded, a malicious device can transmit the transmission again to the vehicle's receiver and gain access.
Based on the make and model of your vehicle, you may be capable of programming new keys by yourself or you may have to employ an automotive locksmith to do it. Certain car manufacturers have an onboard programming procedure however, others require you to have an advanced programmer connected to the OBD2 port.
The most common method of programming new keys for cars is to insert the key fob in the ignition and then turn it on in a specific order. Once the car is in "programming mode," one or more buttons on the fob are pressed to transmit the digital identification code to the computer. The computer then stores this code and then takes the car out of programming mode.
Some manufacturers require that you have a special software programer to program key fobs. These are expensive and are difficult to use for the typical person. It's best to leave the task to an auto locksmith or dealer.
To begin programming for a car with keyless entry start by entering your car from the driver's side and close all doors, except the driver's. This will stop the system from locking your doors while you attempt to program the key. With the ignition key in place and the rest of the keys you wish to program nearby, push and hold the button on the fob that you wish to activate until the danger lights flash twice.
