TRANSPONDER KEY TESTING DEVICE AND METHOD OF TESTING A TRANSPONDER KEY

摘要

This invention relates to a transponder key testing device and to a method of testing a transponder key. The transponder key may be used with any article using transponder key technology, typically a motor vehicle. The transponder key testing device has a first memory (30) in which is stored data relating to an article signal emitted by each one of a number of articles (10) and a second memory (32) in which is stored data relating to a response signal emitted by each one of a number of transponder keys (20). The testing device has a receiver (24) adapted to receive the article signal and the response signal. The testing device compares the article signal with data in the first memory, compares the response signal with data in the second memory, and determines whether or not the transponder key (20) is compatible with the article (10). There is also provided a method of testing a transponder key for compatibility with a particular article.
