Why Dealership May Work Better in Some Cases

Although locksmiths have the skills and equipment to handle various types of vehicles, it is important to note that their services may not be applicable to all cars. Some car manufacturers, particularly German ones, do not share the key reprogramming protocols with locksmiths, making it necessary to seek the services of a dealership for the reprogramming of the key fob.

How Do Locksmiths Reprogram a Key Fob

Generally, locksmiths utilize OBD—II programming. It involves utilizing specialized equipment and cooperation with the car manufacturers. Most auto manufacturers, except for some such as German manufacturers, share programming protocols with locksmiths. This allows them to use a key programmer device to reprogram the keys.

First off, the locksmith identifies the vehicle’s make, model, and year to determine the necessary equipment. Then they connect their key programmer device with the car’s OBD port. They can then add or remove key fobs from the vehicle system. This allows the locksmith to program the new key fob into the system and remove any old key programming if necessary, such as in the case of a stolen key.

There is usually a token system in place for the reprogramming protocol. Locksmiths have to pay for each programming attempt to add a new key fob. This system only permits the equipment to program the car when a pre—paid token is available to use. As such, locksmiths incur some cost for the token at every car key programming attempt, which is taken into account in the service costs,

The entire procedure generally takes only a few minutes. Once the reprogramming is done, the locksmith will test the key fob to ensure the programming procedure was done accurately.
