Slot Antenna Tester

California Residents: Proposition 65 Warning

Use the TDB006 Transponder Antenna Tester to check the antenna used on transponder key systems.

It has an internal antenna with a high gain receiver to pick up the signal from the antenna.

The TDB006 also includes an external antenna wand designed to slide into card readers and slot keys, it can slide into the key slot alongside the vehicle key and pick up the transponder signal being transmitted. 

When the key or card is inserted, the vehicle sends a signal to the transponder inside the key and the TDB006 will pick up this signal and identify that the slot key or card reader is functioning correctly.
