The system also includes security features to prevent the car from crashing in gear, or if someone is not near the steering column. Its computer checks to make sure the transmission is in park and that the brake pedal is turned down before it can start the engine and can be programmed to require a certain number of press-button presses before the motor can start.

suzuki ignis key's smart key fob, like other wireless devices today connects to your car's radio frequency. The transmitter is built into the fob and its signal is picked up by antennas that are located inside and outside of the vehicle. These antennas are similar in design to the ones used by the door locks, and enable the car to know the fob's the range of the fob. Once the receivers detect a signal, they deactivate the immobilizer, which allows the engine to rotate just like a regular key.

Keyless Remote Control

If your key-fob doesn't work, it could be due to a physical problem like broken battery connector contacts or buttons. It could be a software problem that requires reprogramming. A few simple tests with the voltmeter or multimeter can reveal whether or not the battery is still holding an energy level and is capable of operating the microprocessor in the remote.

Modern key fobs utilize RFID (radio-frequency identification) to communicate with the computer of the vehicle. The key fob transmits a digital code to the car's computer. The computer stores it so that the key is able to unlock and start your vehicle.

Immobilizer

The Immobilizer, as you deduce from its name prevents the vehicle from starting without the key fob. The system makes use of LF (low frequency 125 kHz) transmitting antennas inside and outside the vehicle that are activated by key fob's button press or when its handle is pulled. The transponder chip inside the key fob then sends the ID back to vehicle. The module that knows that the vehicle's identification compares the key fob's identification to the one stored in the BCM and if they match the vehicle will be able to start.

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

Most older vehicles have an unreliable, simpler version of this system. It utilizes one code that is personal, that is permanent and has a second code, which changes every time the ignition key is turned. Newer vehicles use an advanced, electronically-controlled Engine Immobilizer system that features two-tier security.
