Reprogramming Car Keys

Transponder keys for car keys are believed to make vehicles safer and are more difficult for thieves to duplicate. However, a key may require reprogramming in the event that it is damaged or lost.

You can change the programming of your key fobs at home, but you must know the right process. For the best results, you must have the following items:

Keys

Nearly all modern vehicles require a transponder fob or transponder keys to operate, providing security and anti-theft protection. These keys are programmed by a locksmith or an authorized dealer to function with the car's systems and specific model. It is expensive to replace them if they're lost, so it's a good idea to have spares available. You can also find replacement keys fobs in various online stores and in many brick-and-mortar auto shops. How can you ensure that the one you purchased is authentic? Are you able to tell whether the unit has been programmed to work with another vehicle, or if it can be programmed differently?

To program a new car key you must first ensure that your car is running. Insert the key you wish to program into the ignition without turning it. You will only have a few seconds before the car's system reverts the commands and then exits programming mode. It is crucial to move quickly and do not delay between each step. To avoid this happening, shut off the engine. You can test the car's security system by turning the key to the "on" position, then back to the "off" position. You should hear a chime indicating that the process was successful. The door locks will be able to cycle.

Certain newer vehicles have rolling key system, which stops thieves from using a stolen car's key to open it. The technology is still susceptible to a method known as replay attack that allows thieves to record the signal of the key fob on the vehicle and then replicate it to unlock the car. To stop this, manufacturers have added a security feature called the CAN bus protocol to thwart attacks on hacking.

Certain manufacturers also have special encryption on their key fobs, that cannot be decoded with an easy program. These kinds of cars require programming by a professional, so you should only attempt this process if you have experience working with electronic devices. Refer to the manual for your car or visit the manufacturer's website to find out how to program it. The steps will vary depending on the type of vehicle.

Transponder chips

Car keys that feature transponder chips require a special reconfiguration to work. While any hardware store can cut keys for you, the real challenge is making it function in conjunction with your particular car. A reprogrammed key will need to be matched with the specific identification number of the vehicle, or it won't start the engine.

Transponder chips are a standard feature of modern cars and are designed to guard against car theft. The chip is a microcircuit which transmits a radio-frequency signal when the ignition key is placed. The car is able to detect the signal, and starts the engine only if the signal is in line with the one programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it much more difficult for thieves who are not experienced to connect a vehicle with hot wires and then start it.

A circuit board with an induction coil connects the chip to the key. When the key is placed in the ignition the magnetic field is generated 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 sent back to the car, and the engine starts if the identification number matches.

There are several methods to program car key a transponder key, however, they all require an instrument that is specifically designed for the purpose. You can buy these tools online or from most locksmiths in the automotive industry. These tools are not expensive, but they are essential for programming the chip in your car.

You may also utilize a transponder that is reprogrammable that was previously programmed for another vehicle. In this case you'll need sure that the key is not damaged or the transponder been altered in any way. You can read the chip with a scanner, or a computer equipped with a USB connector.

The process of reprogramming an transponder's key is simple, but it requires specialized software and a scan tool. If you're new to the process, it's best to seek help from an auto locksmith. Also, avoid buying secondhand keys, as they're likely to be programmed and will not be compatible with your car.

EZ Installer

Prior to recently the time when car owners wanted to replace their keys were required to visit an agent to have it electronically paired with the vehicle. This is because in order for modern keys to function, they need to be "paired". This required expensive and complex equipment that was available only to dealers. The EZ Installer by Car Keys Express simplifies the process of pairing modern keys with vehicles for locksmiths and retailers.
