There are certain things you must be aware of prior to programming your own key fob. The first thing is that the procedure will differ between different automobile models.

Modern cars are usually equipped with an immobilizer. If you don't own the original key to the car, you'll not be able to start the car.

Keyless Entry System

Keyless entry systems make your car more comfortable to drive and can make you feel safer. It allows you to open doors and start the engine without having to look for keys. The system uses radio frequencies to connect the key fobs with the receiver inside the car. The process is relatively simple, and it does not require any special equipment or experience.

When you press the button on your key fob it sends a 40-bit message to a receiver within your vehicle. The receiver matches the code with a function number that determines what action to perform, like unlocking the doors or rolling up the windows. The system is also designed to prevent others from using your key fob to unlock your car, since each transmitter has a unique code.

Modern vehicles have systems that automatically lock your car after you have left. This can be useful for those who are prone to forgetting things or are worried about leaving your vehicle unattended. However, these systems have disadvantages, such as the possibility for thieves to hack into them.

There are a few issues that can cause your keyless entry device and remote starter to fail to perform properly. The most frequent cause is a dead battery on your key fob. You can replace the battery if it is the reason. If this fails it is possible to program your device.

Keyless Start System

This technology allows drivers to start their engines without the need for a mechanical key. The fob instead transmits an access key to the console, that unlocks a set electrical switches that start the engine. Once the engine has begun it can be pressed in order to shut it off.

The system has safeguards to stop the car from getting started accidentally in gear when there is nobody around the steering wheel. The computer will check that the transmission is in Park and the brake pedal pressed before it can start the car. It is also possible to be programmed to demand a specific sequence of button presses.

Like many modern smart keys, Suzuki's key fob is an electronic device that connects to the vehicle via radio frequency. The transmitter is built into the fob and its signal is picked by antennas that are located inside and outside of the vehicle. These antennas, similar to those used by door locks, enable the car to detect when the fob is within range. Once the receivers detect the signal, they will disable the immobilizer and let the car run, just as normal keys would.

Keyless Remote Control

If your key fob isn't work, it could be an issue with the physical part, like damaged battery connector contacts, or a button. It could be a software issue that requires reconfiguring. Simple tests with the voltmeter or multimeter can reveal if the battery active and able to run the microprocessor of the remote.

The newer key fobs communicate with the vehicle computer using RFID (radio frequency identification). The key fob transmits an electronic code to the car's computer, which stores it so that the key can be unlocked and start your vehicle.

The key fobs emit signals in the same frequency as a cellphone, and this technology can be utilized to remotely turn on certain car features like lift gates that power up or to start a vehicle's engine from outside the car. Fobs emit loud sounds to deter thieves and unwanted guests.

Batteries are by far the most frequent cause of the fob's key not working. If this is the case, changing the fob's programming is done by following some simple steps.

Immobilizer

The Immobilizer as you deduce from its name stops the vehicle from starting without a key fob. The system utilizes LF (low frequency 125 milliseconds) transmitting antennas inside and outside the vehicle that are activated by the key fob's button presses or when its handle is pulled. The transponder chip on the key fob sends its ID back to the vehicle. The module that is aware of the vehicle's identity, checks the ID of the key fob with the BCM and If the two match, the vehicle will begin.

This system is very effective at deterring most carjackers, though it does not protect against the more technologically-advanced thieves. In a recent research, security researcher Bokslag was able get into the Immobilizer in three cars by popular brands within ten minutes of getting the keys.

Most older vehicles use a simpler, less reliable version of this system using a unique permanent personal code, and a dynamic second code that's read each time the key is turned on. Newer vehicles use an advanced, electronically-controlled Engine Immobilizer system that features two-tier security.

To reprogramme an authorized key, you need the 7-digit SKC (Skip Key Code) number for the specific vehicle you own. This number is obtained from the dealer when you buy your new Key Fob. You'll also require the Workshop Code and Importer Number. The Immobilizer system is typically not affected by a battery disconnect however the Transponder ECU on the Key Fob will need to be programmed via the OBDII port using the appropriate diagnostic tools.
