When you press the key fob, it will send the 40-bit number to a receiver in your vehicle. The receiver matches the code with a function number that indicates what action to perform, like unlocking the doors or rolling up the windows.

Suzuki's smart key fob, like other wireless devices of today, communicates with your car using radio frequency. The transmitter is built into the fob and its signal is picked by antennas on both sides of the vehicle.

When the receivers detect the signal, they will turn off the immobilizer, allowing the engine to run, just as an ordinary key would.

Keyless Remote Control

If your key fob doesn't work, it could be physical issues, like damaged battery connector contacts or button. It could be a software problem that requires reconfiguring. A few simple tests using an voltmeter or multimeter could confirm that the battery has the charge and is able to run the microprocessor that is inside the remote.

Newer key fobs use RFID (radio-frequency identification) to communicate with the vehicle's computer. They transmit a digital identification code, and the car computer stores this code to ensure that the key fob will be able to unlock and start the car.

The key fobs emit a signal on the same radio frequency as a phone, and this technology is used to remotely control certain car systems, like power lift gates, or to start a vehicle's engine from outside the car. Fobs emit a loud sound to stop thieves from entering the car.

The most frequent reason for a keyfob to stop working is that the batteries need to be replaced. If this is the scenario, changing the fob's program can be done by following a few easy steps.

The system uses LF (low frequency 125 kmhz) transmitting antennas both inside and outside of the vehicle that are activated by the replacement key for suzuki sx4 fob's button press or when its handle is pulled. The transponder chip in the key fob then transmits the ID back to the vehicle. The module that knows the vehicle's identity checks the ID of the key fob against the BCM and when the two match the vehicle will start.

This system is very effective at deterring most carjackers, though it does not protect against the more technologically-advanced thieves. In a recent investigation, security researcher Bokslag was able to slyly hack the Immobilizer in three vehicles of popular brands within ten seconds of getting the keys.

The majority of older vehicles utilize an older, less reliable version of this system, with a single permanent personal code and a changing second code that's read every time the key is switched on. Newer vehicles use an advanced, electronically-controlled Engine Immobilizer system that features two-tier security.
