Car Key Programming
Car key programming is an essential step to ensure that the replacement key fob you purchase is compatible with your vehicle. Without this key, the key will activate the ignition cylinder, but won't start the engine or unlock the doors.
You can easily and quickly program your new keys with a locksmith who has the right equipment. Learn more about this process and why it's important.
Self-Programming
In the lead-up to the 21st century, key technology began to move away from traditional mechanical keys and toward the use of a combination of electronic and physical protocols to prevent theft. The new keys are fitted with a microchip, which needs to be programmed to connect to the electronic system of the vehicle. The best method to reprogram your car keys is by contacting a professional locksmith who has access the appropriate equipment. A lot of vehicles, especially high-end ones, allow only the dealer to create new keys.
The process to do this yourself is different from manufacturer to manufacturer. It usually involves inserting the working spare key into the ignition and then manipulating it (in conformity with the directions in your owner's manual) until your car enters programming mode. This only lasts for only a few minutes before the car exits the programming mode.
When your vehicle is in programming mode, you will need to repeat the process for each key you want to program. The owner's manual should contain specific instructions for the model and key type that you wish to program. Some models have extra security features that must be turned on.
Certain models of cars require an additional code that must be obtained through the dealership at a cost to you. This code guards against "skimming" in the event that a thief tries to read the information on your key through the OBD2 ports in order to steal your car.
This is a great method to save money on a replacement key, however it is important to remember that if the key isn't properly programmed it won't be able to unlock or start the vehicle. J.C.

Key Programmers
If you've lost your car keys, or when you're replacing them, you might wonder whether it's possible to reprogram your key. It's dependent on the vehicle manufacturer, but in the majority of cases you will need to collaborate with an auto locksmith or dealer to program the new key into your vehicle. This requires reprogramming the new key's transponder so that it matches the settings of the car that was originally programmed.
Some vehicles allow you to do it yourself, however most require a professional dealer to utilize a tool that is able to connect to the vehicle and read the programming data from the ECU. The key is then reprogrammed so that it is compatible with the car's settings and you can use it as a regular key.
There are a variety of car key programmers. Some are designed for specific makes and models of vehicles, while others are more universal and can be used on a wide variety of vehicles. Most of these tools come with a small display and a few buttons you press to enter the programming mode. You can then connect the device to an OBD-II connector to read and programm the new key.
Professionals can program a brand new car key in a few minutes, however certain cars require more time and intricate methods to reprogram keys correctly.

Key Fobs
Modern key fobs come with a host of security and convenience benefits. They can replace or enhance traditional car keys and be used to control more than just locking doors; they can start the engine, activate the alarm and perform various other functions.
The key fob uses radio signals to communicate with a receiver 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 the larger access control system. This allows them to track who is entering and leaving and block fobs that have been lost or stolen.
Like all electronic devices key fobs are susceptible to failure periodically. As they are constantly jostled around in pockets and purses, they can become damaged or lose their signal. Even though they're designed to be able to withstand many things, they're not indestructible. After all, they're no more than metal and plastic.
If your key fobs don't working, you may have to replace the battery. Make sure to use the correct battery, and refer to the owner's guide to find out how to replace it correctly. Also, make sure to follow any additional steps to reprogramming or recalibration that might apply.
Wear and tear is a second common reason for failing fobs. As they are continually dropped, bumped into things, and jostled about in purses and pockets they can wear down or even cracked. Sometimes an easy and affordable fix is all that's needed to get your key fobs back functioning.

Keyless Entry
Keyless entry lets you unlock and start your car without having to insert the physical key. It utilizes a radio signal to connect to your car's internal system. You can also control other functions, like the climate controls or music system.
Modern keyless entry systems use rolling code technology to protect against security breaches. However, it's crucial to keep in mind that even this technology has its limitations. By employing a technique dubbed "replay attack," thieves can use the transmitter of the key fob to transmit a message that is recorded by the car's receiver. After the message is recorded, a rogue device 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 might need to hire an automotive locksmith do it for 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 multiple times in a particular sequence. When the car is 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 then takes the car out of programming mode.
Some manufacturers require you to have an advanced computer to program key fobs and some are expensive and difficult to use for the average person. This is why it is generally better to let a professional locksmith or dealer do the work for you.
To set up for a car with keyless entry, enter your vehicle from the driver's seat and close all the doors, with the exception of the driver's. This will prevent the system from locking the doors while you're trying to set up the key. With the key in the ignition along with the other keys you want to program close by, press and hold the button on the fob you want to activate until the danger lights flash twice.
