Summary:

Flexible, unique, and intuitive... In a critical time for the global development of smart key technology, Marquardt are fast establishing themselves as the market leaders for suppliers of smart key systems. This particular development with Audi offers one of the best smart key solutions available, with some unique features which combine good system performance with significantly reduced hardware. Continuing our “World Class Smart Key Benchmarking” research programme, this report explains what makes this system a market leader, as well as giving a full functional analysis and a comparison with UK insurance requirements. This Audi/Marquardt system uses intelligent software to “locate” the position of the remote control, resulting in the need for only three antennae to provide both the smart entry and smart start ranges. Furthermore, the smart start range balances interior coverage with external leakage to provide the best-defined range that we have tested to date. Feature levels are also high on the Audi A4 system, with selective unlock and the display/warning messages providing particularly good customer convenience. All configurable options are accessed through clear and easy-to-use computer menus. A wallet key is also provided for convenience in emergency situations. However, two potential security risks are highlighted in relation to locking a remote control within the vehicle and are detailed in the report.
