The system utilizes radio frequency to connect the key fobs to the receivers inside the car. The process is quite simple and does not require any special equipment or experience.

When you press the key fob, it sends the 40-bit code to an receiver inside your vehicle. The receiver matches that code to an operation code that will tell it what to do, like unlocking the doors or rolling down the windows. The system is designed to prevent other people from using your key fob in order to unlock your car, as each transmitter has its unique code.

Modern cars have systems that automatically lock your car when you walk away. This can be useful in the event that you are susceptible to forgetting things or are worried about leaving your vehicle unattended. However, these systems have their drawbacks, including the possibility for thieves to hack into them.

This technology allows drivers to start their engines without having to use a mechanical key. The fob instead transmits an access key to the console which opens a set of electrical switches and starts the engine. Once the engine is running, a button on the fob can be pressed to shut the motor off.

The system also has security measures to stop the car from starting in gear, or if someone is not in the vicinity of the steering column. The computer will check that the transmission is in Park and that the brake pedal has been pressed prior to allowing the car to begin. It can also be set up to require a certain sequence of presses.

suzuki vitara key programming's smart key fob like other wireless devices of today, communicates with your car through radio frequency. The transmitter is built into the fob, and its signal is picked up by antennas inside and outside the vehicle. These antennas, similar to those used in door locks, enable the car to detect the fob's presence within of the range. Once the receivers detect a signal, they deactivate the immobilizer, allowing for the engine to turn as a normal key.

Keyless Remote Control

If your key fob doesn't function, it could be due to an issue with the physical device, such as broken battery connector contacts or button. It may be a software issue that requires reconfiguring. A few tests with a voltmeter or multimeter should confirm that the battery still holds the charge and is able to run the microprocessor inside the remote.

The newer key fobs connect to the vehicle computer through RFID (radio frequency identification). The key fob sends a digital code and the car computer stores it so that the key can be unlocked and start your car.

The key fobs emit signals in the same radio frequency as a phone, and this technology can be used to remotely activate certain car systems such as power lift gates, or how to program suzuki swift key start a vehicle's engine from outside the car. Fobs can also sound an attention-grabbing blare to scare away criminals and other undesirable guests.

Immobilizer

The Immobilizer as you guess from its name, prevents the vehicle from starting without a key fob. The system utilizes LF (low frequency 125 KHz) transmitting antennas both inside and outside of the vehicle that are activated by the key fob's button press or when its handle is pulled. The key fob's transponder chip transmits its identification back to the vehicle. The module that is aware of 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 article, security researcher Bokslag was able to stealthily hack three popular immobilizers of Car Lockout brands within ten seconds of receiving the keys.

The majority of older vehicles use a less reliable, simpler version of this system. It works with a single personal code, which is permanent as well as a second code that changes each time the ignition key is turned. Newer vehicles use an advanced, electronically-controlled Engine Immobilizer system that features two-tier security.

You'll need the seven-digit SKC (Skip Key Code), that is unique to your vehicle, in order to reprogramme your key. This number can be found by the Dealership when you purchase your new Key Fob.
