6 RKE & RF Monitor
Today's keyless remotes -- also known as key fobs -- make life easier. But when your
key fob stops working or starts to perform sporadically, it will be particularly frustrating.
Check your key fob to make sure it is in top condition so it will work when you really
need it.
Since a key fob is attuned to a special frequency that is only detected by the car for
which it was issued, you will need to use your vehicle to test the fob. Otherwise you will
have to take it to a dealership or an automotive locksmith to have it tested for the right
frequency. But with our TPMS tool, the key fob testing becomes easy and convenient.
1. Use the UP/DOWN scroll button and LEFT/RIGHT scroll button to select RKE & RF
Monitor from Main Menu (Figure 3-2), and press the Y button to confirm.
2. Hold the key fob very close to the tool and press the function buttons on key fob to
test. If the button works and the key fob is sending a signal, the tool will beep and
the screen shows as below. If the button does not work, the tool will do nothing. To
make sure each button is working properly, please test each button in turn.
Figure 6-1 Sample Receive Signal Screen
 The progress bar indicates the approximate power level of the key fob.
 The stronger the signal, the higher the beep tone.
 The tool only tests 315MHz and 433MHz key fobs.
3. Press the N button to return to previous menu.
