Ramsey Kits Are Always Cool, Even In The Summer Heat!
Ahh!!... the conveniences of today's technology in our modern world!
Voice recognition, LED's instead of incandescent bulbs, on-board computers, on-board hard drives, automatic parallel parking, automatic radar cruise
control, and of course, wireless remote controls! They make it so simple,
just have the "key" (called a key fob) somewhere in your pocket or purse, get
near the vehicle, it knows that you are there! Touch the door handle and the vehicle
unlocks. Get in and touch the start button and the vehicle starts. You have yet to use a
key through the whole process! And don't forget all the wireless controls for your house
lights, building access and entertainment systems. They're so great… until they don't
Just like the days of "plugs, points, and condenser" are over, so are the days of having the
hardware store grind out a spare key for your car! Now when your keyless access system
doesn't work, you need to accurately detect what part of the system is malfunctioning. This could be anything
from a dead battery in the key fob, a "brain-dead" key fob, to malfunctioning sensors, antennas, or other system
components in the vehicle. The WCT3 is designed for both the car dealer service shops as well as the consumer.
Until now there was no way to determine where the system was failing. Please note that the WCT3 simply verifies the generation of the control signals. Indication of signal presence is not an indication the encoded data is
valid, nor is it a reader of that code, so don’t worry, this will not help anyone steal your car!
First, let's cover a few basics about vehicular keyless entry. In general, (not all systems are created equal), the
vehicle itself generates a signal at 125 kHz or 20kHz. This is the signal that is used to "talk" to your individual
key fob. Upon receiving the signal, your key fob "returns" a 315MHz signal uniquely encoded with an identification code and unlock command. If the embedded codes of the vehicle and your key fob match, you're in! Once
you have "unlocked" the vehicle, and are inside the vehicle, the presence of your key fob is detected in the same
way when the "start" button is pressed. If the codes match, the vehicle can be started. Some manufacturers
also use Infrared (IR) signals in their key fobs to add additional user control functions to the vehicle. In that
case, the key fob generates a modulated IR signal that is received by the vehicle's IR detectors placed throughout the perimeter of the vehicle.
Testing your system is easy. To test the complete 125 kHz/315 MHz communications path just stand close to
the vehicle with the WCT3 and your key fob in hand. Press the test button and the WCT3 will detect and display
the presence of the vehicle's 125kHz/20KHz signal and, if they "handshake", will also detect and display the
presence of your key fob's 315MHz return signal. You can independently test key fob only signals (panic, lock,
trunk, etc.) by holding the key fob near the WCT3, pressing the test button, and pushing the function button on
the key fob. The same functionality testing can be done with IR key fobs. The modulated IR signal is detected
and will illuminate the IR test LED on the test set. If you know a few "secrets" you can also see if the tire pressure sensors/transmitters are generating signals or the built-in garage door opener in your rear view mirror is
transmitting a signal! But the WCT3's uses go beyond the automotive world. The majority of building wireless
access systems also utilize 125 kHz. Just hold the test set near the building access sensor and the WCT3 will
detect the 125 kHz signal. That will help you troubleshoot door access locations that are not working. It gets
even better... you can use the WCT3 to test virtually any other 315 MHz, 433 MHz, 125kHz, 20kHz and IR wireless control system to verify generation of a signal. We should rename this "the handy-dandy,
universal, wireless remote control tester"!
The WCT3 test set is housed in a compact 2. 25" x 4. 6" x 9" case and is powered by a standard 9VDC battery. The test set is available as a do-it-yourself hobby kit or factory assembled
and tested. For the kit builder, the WCT3 contains both SMT and through-hole components,
with 170 solder points. If you're a car dealer, independent service shop, or simply an owner
of a newer vehicle with keyless entry, or have wireless entertainment controls you can't afford
not to have a WCT3!
