You can reprogram your key fobs at home, but you must be aware of the correct procedure. To get the best results, you should have the following items:

Keys

Almost all modern cars require a transponder key or fob in order to operate, ensuring security and protection against theft. The keys must be programmed to your specific car and its systems by a licensed dealer or automotive locksmith key programming. They are costly to replace if they are lost therefore, you should have spares in your car. You will also find replacement key fobs in various online stores and in many brick-and mortar auto shops. How can you be sure that the one you purchased is authentic? Do you know if the unit has been programmed to work with another vehicle, or if it can be reprogrammed?

If you are planning to program an entirely new key the first step is to ensure that your vehicle is running. Insert the key you'd like to reprogramme into your ignition, but don't turn it. There are only a few seconds left before the system resets all commands and then exits the programming mode. It is crucial to move quickly and don't be patient between each step. Shut off the engine to stop this. Turn the key from "on" to "off" to test the system. The door locks should cycle and you'll hear a chime signalling that the procedure was successful.

Some newer vehicles use rolling keys to stop thieves from using stolen keys to start the vehicle. This technology is still vulnerable to a technique known as a replay attack which allows thieves to record the signal received from the key fob of the car key programer and then replicate it to open the car. To counter this, manufacturers have introduced a security feature called CAN bus protocol to prevent attacks on hacking.

Some manufacturers use a special encryption on their keys that cannot be decoded using a simple program. You should only try this method if your previous experiences are with electronics. Consult your car's manual or go to the website of the manufacturer to learn how to program it. The steps to follow will differ according to the type of vehicle.

Transponder chips

car keys cut and programmed keys that feature transponder chips require a special programming to function. While any hardware store can cut keys for you, the main problem is to make it work in conjunction with your particular car. The key needs to be programmed to match the exact identification number on your car, otherwise it will not start.

Transponder chips, which are used to protect cars from theft are a standard feature of modern cars. The chip is a small microcircuit that transmits a radio-frequency signal when the ignition key is put in. The car then scans for the signal and then starts the engine if it is in line with the original one that was programmed into the vehicle. The car will also shut down if the frequency is not valid. This makes it more difficult for thieves who aren't experienced to hot-wire a vehicle and then start it.

The chip and the key are connected by the circuit board which includes an induction coil. When the key is placed in the ignition, it creates an electric field around the transponder. This produces a signal which gets amplified by the coil which then transmits it to key's identification number. The key's identification number is transmitted back to the car and the engine is started if the identification number matches.

There are several ways to program a key transponder, however each requires the use of a specific tool. These tools can be bought on the internet or at most auto locksmiths. These tools are not expensive, but they are essential for programming your car's chip.

You may also use a resettable key that was programmed for an alternative vehicle. In this scenario you'll need to make sure that the key has not been damaged or that the transponder has been altered in any way. You can read the chip by using a scanner or a computer equipped with an USB connector.

The process of reprogramming the transponder key is easy, but it will require specialized software and a scan tool. It is recommended to contact an auto locksmith for assistance in case you're not an expert. Avoid buying used keys because they may already be programmed and won't work with your vehicle.
