Reprogramming Car Keys

Transponder keys are believed to be more secure for vehicles and more difficult to copy by thieves. However, a key may require reprogramming when it becomes damaged or lost.

You can change the key fobs you own, but you must know the proper procedure. You should have these items to achieve the best results:

Keys

Nearly all modern vehicles require a transponder key or fob to operate, ensuring security and anti-theft protection. The keys are programmed by a locksmith or an authorized dealer to function with your car's system and specific model. It's costly to replace them if they're lost, so it's best to have spares available. You can also find replacement key fobs in various online stores and in many brick-and mortar auto shops. How do you ensure that the new key fob you bought is genuine? Can you tell whether it was programmed to work with another vehicle or if it can be programmed to work with your car?

To program a new car key, first make sure that your vehicle is operating. Insert the key you wish to program a car key into the ignition without turning it. You only have just a few seconds before the car's system resets commands and leaves programming mode. It is crucial to move quickly and don't be patient between each step. To prevent this from happening, shut off the engine. You can test the car's system by turning the key to the "on" position and back to the "off" position. You should hear a sound indicating that the process was successful. The door locks will cycle.

Some newer cars use a rolling key system, which stops thieves from using a stolen vehicle's key to start it. This feature is still vulnerable to a technique known as replay attack which allows thieves to record the signal of the vehicle's key fob and then replicate it to open the car. To prevent this, manufacturers introduced a security feature known as the CAN bus protocols to stop 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. You should only attempt this method if your previous experience is with electronic devices. Consult your car's manual or visit the manufacturer's website to learn how to program it. The steps are different depending on the type of vehicle.

Transponder chips

Car keys with transponder chips require a special reprogramming to function. While any hardware store can cut a new key for you, the biggest challenge is making it function to work with the specific car you own. The key you reprogrammed needs to be compatible with the specific identification number of your car otherwise it won't even start the engine.

Transponder chips, used to prevent car theft are a standard feature of modern cars. The chip is a tiny microcircuit which transmits a radio-frequency signal when the ignition key is inserted. The car detects the signal, and starts the engine only if the signal is in line with the original that was programmed into the vehicle. The car also shuts down if the frequency is invalid. This makes it more difficult for novice car thieves to hot wire a vehicle and start it.

The key and the chip are connected by an electronic circuit board that contains an induction coil. When the key programming car is put in the ignition it creates a magnetic field created around the transponder. This generates a signal that gets taken up by the coil, which sends it to the key's identification number. The key's identification code is returned to the car and the engine will start when the identification number matches.

There are many methods to program a key transponder, but each requires an instrument that is specifically designed for. These tools can be bought through the internet or from many automotive locksmiths. These tools aren't cheap but are essential for programming your car's chip.

You could also use a reprogrammable transponder key that was previously programmed for another vehicle. In this scenario you'll need sure that the key isn't damaged or that the transponder has been altered in any way. You can read the chip by using a scanner or a computer that has a USB connector.

Reprogramming the transponder key is simple, however it requires specialized software and a scan tool. It's best to ask an auto locksmith for assistance for those who are new to the process. You should also avoid buying second-hand keys as they're likely to be programmed and will not work with your vehicle.
