Reprogramming Car Keys

Car keys with transponders are thought to keep cars more secure and are harder for thieves to duplicate. However, keys may need to be reprogrammed in the event that it is damaged or lost.

You can change the programming of your key fobs at home, but you should know the right process. You should have these items to get the most effective results:

Keys

Almost all modern cars require a transponder fob or transponder keys to operate, ensuring security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to work with your car's systems and the specific model. It's expensive to replace them if they become lost, so it's a good idea to have spares available. You can purchase key fobs to replace them in online stores and many brick and mortar auto shops. How can you know that the key you purchased is authentic? Can you tell whether it has been programmed to work with another vehicle or if it is able to be programmed to work with your car?

If you want to program an entirely new key, the first step is to make sure that your car is running. Insert the key that you wish to program into the ignition, but don't turn it. There are only a few seconds before the car's system reverts the commands and then exits programming mode. This is why it is essential to move quickly and not wait between steps. Stop the engine to avoid this. Turn the key from "on" to "off" to test the system. There should be a chime signalling that the procedure was successful. The door locks will cycle.

Some newer vehicles use rolling key technology to prevent thieves from using stolen keys to open the car. The technology is still susceptible to a technique dubbed replay attacks which allows thieves to record the signal of the key fob on the vehicle and then replicate it to unlock the car. To combat this, manufacturers added the security feature known as the CAN bus protocols to ward off hackers from gaining access to the vehicle.

Certain manufacturers also have special encryption on their key fobs which cannot be decoded by an easy program. These types of cars require to be programmed by a professional. Therefore, you should only try this only if you've worked with electronics. It's a good idea to refer to the owner's manual for your car or search for the manufacturer on the internet, since the steps differ based on vehicle type.

Transponder chips

Car keys that feature transponder chips require special reconfiguration to work. While any hardware store can cut keys for you, the real problem is to make it work to work with the specific car you own. A key that has been reprogrammed will need to match the exact identification number of your car otherwise it won't even start the engine.

Transponder chips, which are used to stop theft of cars, are a common feature of modern cars. The chip is a microcircuit which transmits a radio frequency signals when the key is placed into the ignition. The car then detects the signal and begins the engine if it matches the original one that was programmed into the vehicle. The car will also shut down if the frequency is invalid. This makes it harder for thieves who aren't experienced to wire a vehicle hot and then turn it on.

A circuit board equipped with an induction coil that connects the chip to the key. When the key is placed in the ignition it creates a magnetic field generated around the transponder. This creates a signal that gets taken up by the coil, which sends it to the key's identification number. The key's ID number is then sent back to the vehicle and if it matches the engine will begin to run.

There are many ways to program a transponder, but all of them require the use of a specific tool. You can buy these tools online or from most automotive locksmiths. They are not cheap, but they're essential for programming the chip to your vehicle.

You can also use an resettable key that was programmed for another vehicle. In this instance you'll need sure that the key isn't damaged or the transponder has been altered in any way. To do this, you can use scanners or a computer with an USB port to identify the chip and establish its identity.

Reprogramming an transponder is a simple process, but requires specialized software. It also requires an scanner tool. It is recommended to contact an auto locksmith for assistance in case you're not an expert. Don't buy used keys since they may already be programmed and will not work with your car.
