Transponders in car keys are thought to keep vehicles more secure and less likely to be duplicated by thieves. A key may have to be reprogrammed in event of damage or lost.

Keys

Almost all modern cars require some kind of transponder key or fob in order to operate, providing security and anti-theft protection. These keys must be programmed to your particular vehicle and its features by a certified locksmith or dealer. It's costly to replace them if they become lost, so it's better to have spares in your possession. You will also find replacement key fobs in various online stores and in many brick-and mortar auto shops. But how can you tell that the one you purchased is genuine? Do you know if the unit has been programmed to work with a different vehicle or if yours can be programmed again?

If you are planning to program a new key first, you need to make sure that your car is running. Insert the key that you want to reprogramme into your ignition, but don't turn it. You only have a few seconds before the car's system resets commands and exits 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. You should hear a sound signalling that the procedure was successful. The door locks will go through a cycle.

Certain newer vehicles utilize rolling key technology to prevent thieves from using stolen keys to start the car. This technology is still vulnerable to a technique known as replay attack that allows thieves to record the signal received from the key fob of the car and reproduce it later to open the car. To prevent this, manufacturers have added the security feature known as the CAN bus protocols to prevent hackers from gaining access to the vehicle.

Certain manufacturers also have special encryption on their key fobs that cannot be decoded with an easy program. You should only try this method if your previous experiences are with electronic devices. It is recommended to refer to the owner's manual for your car or look up the manufacturer online, as the steps will differ depending on the vehicle type.

Transponder chips

Car keys with transponder chips require special reprogramming in order to work. Any hardware store can offer you a new car keys programmer key, however the real challenge lies in implementing it to your car. The key must be programmed to match the exact identification number of your car, otherwise it won't start.

Transponder chips, which are used to stop theft of cars are a standard feature of modern cars. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is placed. The car then detects the signal and starts the engine if it matches the original frequency that was programmed into the vehicle. The car will also shut down if a frequency is invalid. This makes it more difficult for novice car thefts to wire a vehicle hot 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, a magnetic field is created around the transponder. This produces a signal which is taken up by the coil, which then transmits it to key's identification number. The ID number of the key is sent back to the vehicle and if it is in line with the engine will begin to run.

There are a few different methods to program a transponder key, but they all involve using a special tool. You can buy these tools on the internet or at many locksmiths in the automotive industry. These tools are not inexpensive, but they are vital to program your car's chip.

You can also utilize a transponder that is reprogrammable that has been previously programmed for another vehicle. In this scenario you'll need to make sure that the key is not damaged or the transponder been altered in any way. To check this, you can use scanners or a computer with an USB port to scan the chip and determine its identity.
