Key checks

18 October 2013  

The TDB002 Transponder Tester quickly checks if a key or remote control has a working transponder fitted. It will work on most vehicle, truck and motorbike keys and remotes – checking that data is being sent and at what frequency. The gadget, available from The Diagnostic Box, will run for at least 20 hours on three AA batteries and powers off if left unused to save battery life.
