Car Key Programming

Professional locksmiths equipped with the required equipment can reprogram your keys. Many cars, particularly high-end ones, require that only the dealer is allowed to make new keys.
If you want to try this yourself, the process is different for each manufacturer. It usually involves inserting the spare key that works into the ignition and then manipulating it (in accordance with the instructions in your owner's manual) until your car enters programming mode. It is necessary to be quick, as this only lasts a few seconds before your car exits the mode.
You'll need repeat this procedure for each key you want to program once your vehicle is in the programming mode. The instructions in your owner's manual should be specific to the type of key and model you're trying to program, as some models have additional security features that have to be enabled (for instance, a passcode that is required to access certain programming modes).
Some models also require a code that you can only get through a dealer for a fee. This code helps protect against "skimming" which happens the process where thieves attempt to read the information of your key through the OBD2 port to start the car, and then steal it.

Many of these devices come with small displays and a variety of buttons to switch between programming modes. Then, plug the device into an OBD-II connector to begin reading and programming the new key.

Key Fobs
Modern key fobs provide numerous convenience and security advantages. They replace or supplement traditional car keys and can control more than only locking doors. They can start the engine, trigger the alarm and perform other functions.
The key fob uses radio signals to communicate with a receiver that is installed in the vehicle. When you press the button on the keyfob, it transmits the code to the receiver, which performs the desired function. Key fobs are also popular with commercial building owners, who can integrate them into an access control system. This lets them track who enters and exits, and they can block fobs which have been taken or lost.
Key fobs, as with any electronic device, can malfunction. Because they are constantly tossed around in purses and pockets they are prone to damage or lose their signal. And although they are built to be able to withstand some punishment, they're not impervious to damage; after all, they're little more than metal and plastic.
If your key fobs don't working, you may need to replace the battery. Make sure you use the correct battery, and refer to your owner's manual to learn how to replace it properly. Be sure to follow all other steps needed for reprogramming and calibration.
Another common cause of failed fobs is simple wear and wear and tear. When they are constantly dropped, pushed into objects and tossed around in purses and pockets, they can become worn down or even cracked. A simple and inexpensive fix can often be all you need to make your key fobs work again.

Keyless Entry
Keyless entry allows you to unlock your car and start it without the need to insert a physical key. It utilizes a radio signal to connect to your car's internal system. You can also control different features, like the climate controls or music system.
Modern keyless entry systems use rolling code technology to safeguard against security breaches. It's important to remember that even this technology is not 100% secure. Utilizing a technique known as "replay attack," thieves can make use of the transmitter of the key fob to send a message that is recorded by the vehicle's receiver. Once the message is recorded, a rogue device can retransmit the same transmission to the vehicle's receiver and gain access to the property.
Based on the model and make of your vehicle, you might be able to program new keys yourself, or hire an automotive locksmith to do it. Some car companies have a special onboard programming process however, others require you to have an advanced programmer connected to the OBD2 port.
The most popular method of programming new keys for cars is to put the key fob in the ignition and then turn it on in a particular 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 then saves this code and then takes the car out of programming mode.
Certain manufacturers require you to use a specific advanced programmer to program key fobs. They are costly and hard to use by the typical person. It is recommended to delegate the work to an automotive locksmith or dealer.
To set up the keyless entry system begin by stepping into your vehicle from the driver's seat 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 automotive key programming and the rest of the keys you wish to program in the vicinity, push and hold the button on the fob you want to activate until the hazard lights flash twice.
