The Top Suzuki Swift Replacement Key Gurus Are Doing 3 Things
Suzuki Key Fob Programming
Before you try to program your key fob on your own, there are some things you need to be aware of. First, the procedure will differ for different car models.
Most modern cars are equipped with an immobilizer. If you don't own the original key for the car, you will not be able start it.
Keyless Entry System
A keyless entry system can make your car more comfortable to drive, and also improve security by permitting you to open the doors and start the engine without having to look for your keys. The system uses radio frequencies to connect the key fobs with the car's receiver. The process is easy and does not require any special equipment or prior experience.
When you press the button on your key fob, a 40-bit signal is sent to a receiver in your vehicle. The receiver matches that code with an operation code that will tell it what to do, such as opening the doors or rolling down the windows. The system is also designed to keep others from using your key fob to open your car, since each transmitter has a unique code.
Modern cars are equipped with systems that automatically lock your car after you leave. This is useful for those who are prone to not remembering things or worry about leaving your vehicle unattended. These systems aren't without their faults. For instance, thieves could hack into these systems.
There are a variety of 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 this is the issue. If this doesn't work it is possible to have your fob programmed.
Keyless Start System
This technology lets drivers start their engines without the need for an electronic key. Instead, the fob transmits an access code to the console that allows a series of electrical switches which activate the engine and allow it to start. Once the engine is running, a button on the fob can be pressed to shut the motor off.
The system also comes with safeguards to prevent the car from beginning in gear, or when someone is not in the vicinity of the steering column. The computer makes sure that the transmission is in park, and that the brake pedal is pulled down before allowing the engine's start and can be programmed to require a particular sequence of buttons before the motor will run.
Like other modern smart keys Key fobs from Suzuki are an electronic device that communicates with the car via radio frequency. G28CarKeys is built into the fob and its signal is picked up by antennas both inside and outside of the vehicle. These antennas, which are similar to those used by door locks, enable the car to recognize when the fob is in of the range. Once the receivers detect the signal, they'll disable the immobilizer and allow the engine to run, just as an ordinary key would.
Keyless Remote Control
If your key-fob doesn't work, it may be due to an issue with its physical components, like broken battery connector contacts or buttons. It may be a software issue that needs reprogramming. A few tests with the voltmeter or multimeter can confirm that the battery still holds a charge and is able to run the microprocessor that is inside the remote.
Newer key fobs use RFID (radio-frequency identification) to communicate with the computer in the vehicle. They transmit a digital identification code, and the car computer stores 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 car systems, such as lift gates that power up or even start the engine of a vehicle from outside. Fobs also can trigger an attention-grabbing blare to scare off thieves and other unwanted guests.
Batteries are the primary cause of a key fob not working. If this is the scenario, reprogramming the fob is done by following the steps below.
Immobilizer
As you can guess from the name, the Immobilizer stops the engine of the vehicle from starting without a key fob. The system uses LF (low-frequency 125 KHz) transmitting antennas which are activated when the key fob is held or its handle is pulled. The transponder chip in the key fob sends its ID back to the vehicle. The module that knows about the vehicle's identity compares the ID of the key fob against the BCM and should 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 study security researcher Bokslag was able to slyly break the Immobilizer on three vehicles belonging to popular brands within ten seconds of getting the keys.
Most older vehicles employ an older, less reliable version of this system, with a single, permanent personal code and a constantly changing second code that is 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, it is necessary to know the 7-digit SKC (Skip Key Code) number for your specific vehicle. This number is retrieved from the Dealership when you buy your new Key Fob. It also requires 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 reprogrammed through the OBDII port using the appropriate diagnostic tools.
