Speak "Yes" To These 5 Suzuki Swift Replacement Key Tips
Suzuki Key Fob Programming
Before you attempt to program your key fob on your own, there are a few things that you should be aware. The first thing you need to know is that the procedure for programming will differ from car models.
Modern cars are usually equipped with an immobilizer. This means that if you don't possess the original key, you won't be able to start the vehicle.
Keyless Entry System
A keyless entry system makes your car easier to drive, and it can make you feel more secure. It lets you open doors and start the motor without having to look for keys. The system uses radio frequencies to connect the key fobs to the car's receiver. The process is simple and does not require special equipment or prior experience.
When you press the key fob, it broadcasts an encrypted 40-bit code to a receiver in your vehicle. The receiver matches the code with a function code which tells it what action to take, such as unlocking the doors or opening the windows. The system is designed to block other people from using your key fob in order to open your vehicle, because each transmitter has its own unique code.
Modern cars have systems that automatically lock the car after you've walked away from it, which could be beneficial if you tend to forget things or worry about leaving your car unattended. However, these systems have some drawbacks, for instance, the possibility of thieves being able to hack into them.
There are a few problems that can cause your keyless entry system and remote starter to fail to function properly. The most common issue is a dead battery on your key fob. If this is the case, you can try replacing the battery inside your fob. If this doesn't solve the issue, you might require having your fob programmed again.
Keyless Start System
With this technology drivers can begin their engine without needing to insert a mechanical key. Instead, the fob transmits an access code to the console which unlocks a series of electrical switches to activate the engine and then start it. Once the engine is running it is possible to press a button on the fob can be pressed to turn off the motor off.
The system also features security features to prevent the car from starting in gear or when a person is not within the steering column. The computer will ensure that the transmission is in Park and the brake pedal is pressed prior to allowing the car's engine to start. It is also possible to be configured to require a certain sequence of presses.
Suzuki's smart key fob like other modern wireless devices communicates with your car's radio frequency. The transmitter is built into the fob, and its signal is picked up by antennas inside and outside of the vehicle. These antennas, similar to those used by door locks, enable the car to detect when the fob comes within the range. When the receivers receive an indication, they shut off the immobilizer and allow the engine to operate like a regular key.
Keyless Remote Control
If your key fob does not work, it could be an issue with the physical part, like damaged battery connector contacts or button. It could also have an issue with software that requires the reprogramming. A few simple tests with the voltmeter or multimeter can reveal whether or not the battery still holds a charge and is capable of operating the microprocessor in the remote.
The latest key fobs communicate with the vehicle computer using RFID (radio frequency identification). The key fob transmits an electronic code to the car's computer. The computer stores it so that the key can be opened and start your car.
Key fobs emit a signal in the same frequency as a cellphone, and this technology can be employed to remotely trigger certain car systems, like lift gates that power up or to start the engine from outside the car. Fobs can also emit an attractive blare to frighten away criminals and other undesirable guests.
Batteries are by far the most frequent reason for a key fob not working. Follow suzuki key fob programming G28 to reprogram the fob if this is the situation.
Immobilizer
The Immobilizer, as you deduce from its name prevents the vehicle from beginning without the key fob. The system uses LF (low-frequency 125 kHz) transmitting antennas, which are activated when the key fob is either pressed or its handle is pulled. The transponder chip in the key fob then transmits the ID back to the vehicle. The module that is aware of the identity of the vehicle checks the ID of the key fob with the BCM and should 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 report security researcher Bokslag managed to hack three popular immobilizers of car brands within a matter of ten seconds after receiving the keys.
The majority of older cars use a simpler, less-reliable version of this system, that has a single permanent personal code, and a dynamic second code that's read each time the key is switched on. Newer vehicles use an advanced, electronically-controlled Engine Immobilizer system that features two-tier security.
To reprogram an authorized key, you will need the 7 digit SKC (Skip Key Code) number that is specific to your vehicle. This number can be obtained by the dealer when you purchase your new Key Fob. You'll also require the Workshop Code and Importer Number. The Immobilizer system usually is not affected by a disconnect of the battery however the Transponder ECU on the Key Fob will need to be programmed via the OBDII port with the right diagnostic tools.
