Suzuki Key Fob Programming
Before you attempt to program your key fob yourself, there are some points you should be aware. First, you must know is that the process of programming is different for different models of cars.
Most modern cars come with an immobilizer. This means that if you don't have the original key, you won't be able to start the vehicle.
Keyless Entry System
Keyless entry systems make your car easier to drive, and can help you feel safer. It allows you to open doors and start the motor without having to look for keys. The system uses radio frequencies to connect the key fobs to the receiver inside the car. The process is relatively simple and does not require any special equipment or past experience.
When you press the key fob, it transmits the 40-bit code to an receiver in your vehicle. The receiver matches the code with a function code that determines what action to take, such as unlocking the doors or rolling up the windows. The system is also designed to prevent other people from using the key fob as a way to open your car, since every transmitter has a unique code.
Modern cars come with systems that automatically lock the vehicle when you've gone away from it. This is useful if you tend to forget things or worry about leaving your vehicle unattended. However, these systems have their disadvantages, like the ability for thieves to hack into them.
There are many issues that could cause the keyless entry system and remote starter not to work correctly. A dead battery in your fob is the most frequent problem. If this is the case, attempt replacing the battery in your fob. If this doesn't fix the problem, you may require having your fob reprogrammed.
With this technology, drivers can start their engines without having insert a mechanical key. Instead, the fob sends an access key to the console which unlocks a set of electrical switches that start the engine. Once the engine is running it is possible to press a button on the fob can be pressed to shut the motor off.
The system has safeguards that stop the car from getting started by accident in gear even though nobody is around the steering wheel. Its computer checks to make sure the transmission is in neutral and the brake pedal is pulled down before allowing the engine to begin and it could also be set to require a specific sequence of buttons before the motor will run.
Suzuki's smart key fob, like other modern wireless devices communicates with your car using radio frequency. The transmitter is built into the fob and its signal is picked up by antennas in and outside the vehicle. These antennas, which are like those used for door locks, enable the car to detect the fob's presence within range. Once the receivers detect the signal, they turn off the immobilizer, allowing the engine to operate like a normal key.
Keyless Remote Control
If your key fob won't work, it could be due to an issue with the physical structure, such as broken battery connector contacts or buttons. It could be a problem with software that needs reprogramming. Simple tests with a multimeter or voltmeter will show if the battery is still charged and able to run the microprocessor inside the remote.
Key fobs that are newer use RFID (radio-frequency identification) to communicate with the computer of the vehicle. They transmit a digital identity code to the car computer saves this code to ensure that the key fob can unlock and start the car.
The key fobs transmit signals at the same frequency as phones do. This technology can be used to remotely turn on automobile systems, like lift gates that power up or even start the engine of a vehicle from outside. Fobs can also emit an alarming sound to scare off thieves and other unwanted guests.
Batteries are the main reason for an unresponsive key fob. Follow a few easy steps to reprogram the fob in this case.
Immobilizer
Based on the name, the immobilizer prevents the engine from running without the key fob present. The system makes use of LF (low frequency of 125 milliseconds) transmitting antennas both inside and outside the vehicle that are activated by key fob's button press or when its handle is pulled. The transponder chip on the key fob sends its ID back to the vehicle. The module that knows the vehicle's identity checks the key fob's identification to the one stored in the BCM and, if they are compatible the vehicle can 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 managed to hack three popular Immobilizers for cars within a matter of ten seconds after receiving keys.
Most older vehicles have an older, less reliable version of this system. It uses one code that is personal, that is permanent as well as 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.
You'll need the seven-digit SKC (Skip Key Code), that is specific to your vehicle, to reprogram a key. This number is obtained from the Dealership when you purchase a new Key Fob. You will also require the Workshop Code and Importer number. The Immobilizer system won't be affected by a battery disconnect however, you will require the correct diagnostic tools to reprogram the Transponder ECU in the Key Fob.
