Suzuki Key Fob Programming
There are certain things you should know before trying to program your own key fob. The first thing you need to know is that the process of programming will differ for different car models.
The majority of modern vehicles have an immobilizer system. This means that if you don't have the original key, you won't be able to start the car.
Keyless Entry System
Keyless entry systems make your car easier to drive and can make you feel safer. It lets you open doors and start the motor without having to reach for keys. The system uses radio frequencies to connect the key fobs to the car's receiver. The process is quite simple and does not require any special equipment or prior experience.
When you press a button on your key fob, it transmits the 40-bit number to a receiver in your vehicle. The receiver matches the code with a function code that indicates what action to do, such as opening the doors or rolling up the windows. The system is also designed to stop other people from using your key fob to unlock your car, since every transmitter has a unique code.
Modern cars are equipped with systems which automatically lock the car after you've walked away from it, which could be beneficial if you are prone to forgetting things or worry about leaving your vehicle unattended. However, these systems come with their drawbacks, including the ability for thieves to hack into them.
There are many problems that can cause the keyless entry system and remote starter to not function properly. The most frequent cause is a dead or dying battery in your key fob. If this is the case, you can try replacing the battery inside your fob. If this doesn't fix the issue, you may need to have your device reset to its original programming.
Keyless Start System
This technology lets drivers start their engines without having to use an electronic key. The fob instead sends an access key to the console which unlocks a set of electrical switches, and then starts the engine. Once the engine is started, the fob's button can be pressed to turn it off.
The system comes with safeguards that ensure that the car is not started without intention when there is no one at the steering wheel. The computer will ensure that the transmission is in Park and the brake pedal pressed before allowing the car to begin. It can also be programmed to require a certain sequence of presses.
As with other modern smart keys, Suzuki's key fob is a wireless device that connects to the car via radio frequency. The transmitter is built into the fob, and its signal is picked by antennas on both sides of the vehicle. These antennas, like those used for door locks, enable the car to sense when the fob is within the range. If the receivers detect an indication, they shut off the immobilizer, allowing for the engine to turn over just like a regular key.

If your key fob isn't work, it could be a physical issue such as broken battery connector contacts or button. It could also have an issue with the software, which requires the reprogramming. Simple tests using a multimeter or voltmeter will determine if the battery is still charged and is able to run the microprocessor inside the remote.
The latest key fobs communicate with vehicle computer using RFID (radio frequency identification). They transmit a digital identity code, and the car computer saves this code to ensure that the key fob can unlock and start the car.
The key fobs transmit a signal at the same frequency as a cell phone. This technology can be used to remotely activate car systems, such as lift gates that can be powered or even start the engine of a vehicle from outside. Fobs emit loud sounds to stop thieves from entering the car.
The most frequent reason for a key fob's device to stop working is because the batteries have to be replaced. If this is the case, reprogramming the fob is done by following a few simple steps.
Immobilizer
As you might guess from the name, the immobilizer prevents the vehicle's engine from starting without a key fob. The system makes use of LF (low frequency of 125 milliseconds) transmitting antennas both inside and outside the vehicle. They are activated by the key fob's button press or when its handle is pulled. The transponder chip that is on the key fob is then able to transmit the ID back to vehicle. The module that knows about the vehicle's identity, checks the ID of the key fob against the BCM and If the two 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 research, security researcher Bokslag was able to slyly break the Immobilizer on three vehicles belonging to popular brands within ten seconds of getting the keys.
The majority of older vehicles utilize the 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 reprogram an authorized key, you need the 7-digit SKC (Skip Key Code) number that is specific to your vehicle. This number is obtained from the dealer when you buy your new Key Fob. You will also require the Workshop Code and Importer number. The Immobilizer system won't be affected by a disconnected battery, but you will need the correct diagnostic tools in order to reprogram the Transponder ECU in the Key Fob.
