Car Key Programming
Car key programming is a crucial step to ensure that the replacement key fob you purchase will work with your car. Without this, the key will engage the ignition cylinder, but will not start the engine or unlock the doors.
It is easy and quick to program your new keys using locksmiths with the right equipment. Read on to learn more about the process and the importance of it.
Self-Programming
In the early years of the 21st century, car keys technology began to shift away from mechanical keys to an amalgamation of physical and electronic protocols to stop theft. Most of these new keys have a microchip integrated into them that must be programmed to link the vehicle's electronic system. The best way to reprogram your car keys is by contacting a professional locksmith with access to the right equipment. Many vehicles, particularly luxurious ones, will only allow dealers to create new keys.
The procedure to do this yourself is different from manufacturer to manufacturer. It usually involves inserting the working spare key into the ignition, and manipulating it (in conformity with the directions in your owner's manual) until your car is in programming mode. It is necessary to move quickly because this will only last only a few seconds before your car exits the mode.
Once your vehicle is in programming mode, you'll need to repeat the process for each key you'd like to program. The instructions in the owner's manual are specific to the type of key and model that you are trying to program car key, as certain models have additional security features that have to be activated (for instance, a passcode that is required to enter certain programming modes).
Some models of vehicles also require an additional code that can only be obtained from the dealer at a cost to you. This code helps protect you from "skimming" in the event that thieves attempt to read the information on your key via the OBD2 ports in order to steal the car.
This is a great way to save money on a replacement car key, but it's important to remember that if your car key isn't properly programmed, it won't unlock or start the car.

Key Fobs
Modern key fobs come with numerous advantages in terms of security and convenience. They replace or supplement traditional car keys and 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 does the job you want it to. Key fobs are also popular with commercial building owners who can integrate them into an access control system. This lets them monitor who enters and leaves and also block fobs that have been lost or stolen.
As with any other electronic device keys can fail from time to time. They can be damaged or lose their signal if they are placed in purses and pockets. While they are able to endure many abuses however, they're not impervious to damage. After all, they are made of metal and plastic.
If your key fobs aren't working, you may need to replace the battery. Make sure to use the correct battery, and refer to your owner's manual to learn how to replace it correctly. Be sure to follow any additional steps needed for reprogramming and calibration.
Wear and tear is another frequent cause of failing fobs. When they are constantly dropped, bumped into things and tossed around in purses and pockets they can wear down or even cracked. Oftentimes, a quick and inexpensive fix is all that is required to get your key fobs back functioning.

Keyless Entry
Keyless entry is a feature that lets you unlock and start your car without having to insert an actual key. It utilizes a radio signal to communicate with the car's internal system. You can also control various features, such as the climate control or music system.
Modern keyless entry systems use rolling code technology to guard against security breaches. It's important to remember that even this technology isn't completely secure. Utilizing a technique known as "replay attack" thieves can use the key fob's transmitter to transmit a message that is recorded by the vehicle's receiver. After the message is recorded, a rogue gadget could retransmit the message to the vehicle receiver and gain access.
Based on the model and make, it may be possible to program new keys on your own, or you may need to have an automotive locksmith assist you. Certain car manufacturers have a special onboard programming process however, others require you to have an advanced programmer connected to the OBD2 port.
The most popular method to program new car keys is by putting the key fob into the ignition and engaging it repeatedly in a certain 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 stores this code and takes the car key cut and program out of programming mode.
Certain manufacturers require you to have a special advanced programmer to program key fobs and some of them are costly and difficult to use by a typical person. It's best to leave the task to an auto locksmith or dealer.
To begin the process of programming a new keyless entry car key, enter your vehicle from the driver's side and close all the doors, with the exception of the driver's door. This will prevent the system from locking the doors while you're trying to set up the key. Press and hold the button on the fob you wish to activate while the ignition is on and the other keys you wish to be programmed nearby. The warning light will flash twice.
