This feature is vital since it can save time and money since you don't need to wait for the correct part from a different country.

Transponder Chips

A lot of modern cars come with transponder chips that communicate with the computer system of the car. The chip emits a digital code each time the key is placed in the ignition barrel. This unique code recognizes the key as a valid key. This technology adds an additional layer of security to modern vehicles, and reduces the risk of theft. However, to take advantage of this added security feature the key must be cut correctly and programmed. A licensed auto locksmith or car dealership can provide this service.

The first step in a transponder key reprogramming process is to ensure that the key's blank contains an appropriate type of transponder or circuit board. The key should be compatible with the on-board computer of the vehicle and include a keyring that is correctly positioned around the ignition barrel.

This type of reprogramming is typically performed using the transponder cloning machine that can copy a particular circuit board or transponder. Some of the major blank manufacturers as well as some experts in reprogramming provide this equipment. The device that is cloned must be able to read the data that is sent on each of the transponders which are being copied. Some cloning devices are upgradeable and can be used to copy the most recent transponders when they are released.

Many automakers now require keys to transmit the unique VIN number of the vehicle as well as the transponder code. These additional security measures often require special key programming procedures which are not accessible to independent mechanics unless the have access to a dealer only tool like Autel's Immobilizer scanner tool IM608 or Launch Tech’s XProg3 scanner.

When programming a new key, it is crucial to choose the right PIN that is easy to remember, but difficult for someone else to figure out. The majority of experts recommend a combination of numbers and letters. Avoid using personal information such as birthdates, telephone numbers, or social security numbers.

If the destination doesn't require an actual copy of the data, this may not be an issue - however, it could be a problem when the data is changing or needs to be updated constantly. The ideal situation is that one copy of data should be destroyed after it's no longer required.

This credential allows technicians to access the vehicle's PIN code and immobilizer codes by using the Secure Data Release Model of the National Automotive Service Task Force.

Also, ensure that the shop has scanners that are able to handle the process. The scanners will need to be able to extract the PIN code from the modules, and allow technicians to program new keys. In addition, a lot of OEMs require that keys communicate more than its ID code. VW, Chrysler and other manufacturers require that the key also transmits the unique VIN number of the vehicle. These additional transmissions can be programmed by using the key programming tool.
