Car Key Programming

Car key programming is a crucial step to ensure that the replacement key fob that you purchase works with your vehicle. Without car key programming , the key will engage the ignition cylinder, but will not start the engine or open the doors.

A locksmith equipped with the right equipment can program your new car keys quickly and effortlessly. Find out more about the procedure and the importance of it.

Self-Programming

In the early years of the 21st century, key technology started to move away from traditional mechanical keys to a hybrid of electronic and physical protocols to guard against theft. Most of these new keys are equipped with a microchip within them that must be programmed to connect them to your vehicle's electronic system. Professional locksmiths with the necessary equipment can reprogram your keys. Many cars, particularly luxury cars, require that only the dealer is allowed to create new keys.

If you'd like to attempt this yourself, the method differs by manufacturer. In general, you'll need to insert the spare key in the ignition and manipulate it (according to the instructions in your owner’s manual) until the car enters programming mode. It only takes just a few seconds before the car is out of programming mode.

You'll have to repeat this process for each key you want to program once your vehicle is in the programming mode. The instructions contained in the owner's manual must be specific to the key type and model you want to program, since some models come with additional security features that have to be activated (for instance, a passcode that is required to access certain programming modes).

Some models of vehicles also require an additional code that must be obtained from the dealership for a fee to you. This code helps protect you from "skimming" which occurs when thieves try to read the information on your key via the OBD2 ports to steal your car.

This is a great method to save money on a replacement car key, but it's important to remember that if the key isn't programmed correctly it won't be able to unlock or start the car. J.C.

They can keep track of who enters and exits and can prevent fobs from being lost or stolen.
