10 Suzuki Swift Replacement Key Strategies All The Experts Recommend
There are a few things you should know before trying to program your own key fob. First, the procedure will differ for different automobile models.
Most modern cars are equipped with an immobilizer. This means that if you don't have the original key that you used, you won't be able to start the car.
Keyless Entry System
Keyless entry systems can make your car more comfortable to drive in addition to increasing security by allowing you to open the doors and start the engine without reaching for your keys. The system utilizes radio frequency to connect the key fobs and receivers inside the car. The process is fairly easy and does not require any special equipment or previous experience.
When you press the key fob, it transmits the 40-bit code to an receiver inside your vehicle. The receiver matches that code to an operation code that instructs it on what to do, like opening the doors or opening the windows. The system is designed to prevent other people from using your key fob to open your vehicle since each transmitter has its unique code.
Modern cars have systems that automatically lock the car after you have walked away from it, which is useful if you are prone to forgetting things or worry about leaving your vehicle unattended. However, these systems have their disadvantages, like the ability of thieves to hack into them.
There are a few issues that can cause your keyless entry device and remote starter to fail to perform as expected. The most common cause is a dead battery on your key fob. You can replace the battery if this is the reason. If this doesn't fix the issue, you might need to have your fob reprogrammed.
Keyless Start System
With this technology drivers can begin their engine without having to insert an electronic key. Instead, the fob sends an access code to the console which unlocks a series of electrical switches that turn on the engine and then start it. After the engine has been started it can be pressed in order to shut it down.
The system has safeguards to stop the car from getting started accidentally in gear when no one is near the wheel. The computer will check that the transmission is in Park and that the brake pedal is engaged prior to allowing the car to start. It can also be programmed to require a specific sequence of button presses.
Like many modern smart keys Key fobs from Suzuki are an electronic device that communicates with your vehicle via radio frequency. The transmitter is embedded in the fob and its signal is picked up by antennas inside and outside the vehicle. These antennas are similar to the ones used by door locks, and they allow the car to detect when the fob is in its range. When the receivers receive an indication, they shut off the immobilizer, allowing for the engine to rotate just like a regular key.
Keyless Remote Control
If your key fob does not work, it could be due to a physical problem like broken battery connector contacts or buttons. It could also have an issue with the software, which requires reprogramming. Simple tests with an voltmeter or multimeter determine if the battery is active and able to run the microprocessor in the remote.
The latest key fobs communicate with vehicle computer through RFID (radio frequency identification). The key fob transmits a code to the car's computer. The computer stores it so that the key is able to unlock and start your car.
The key fobs emit a signal on the same radio 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 a vehicle's engine from outside the vehicle. Fobs can also trigger an attention-grabbing blare to frighten away thieves and other unwanted guests.
The most common reason for a key fob to stop working is that the batteries have to be replaced. Follow these steps to reprogramme the fob in this case.
Immobilizer
The Immobilizer, as you imagine from its name, stops the vehicle from starting without the key fob. The system utilizes LF (low-frequency 125 KHz) transmitting antennas, which are activated when the key fob is press or its handle is pulled. The transponder chip that is on the key fob transmits the ID back to the vehicle. The module that is aware of the vehicle's identity compares the ID of the key fob with 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 report security researcher Bokslag managed to stealthily crack three popular car brands' Immobilizers within ten minutes of getting keys.
The majority of older vehicles use an unreliable, simpler version of this system. It is based on one code that is personal, that is permanent and has 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.
In order to reprogramme an authorized key, you need the 7-digit SKC (Skip Key Code) number that is specific to your vehicle. This number can be retrieved by the dealer when you purchase your new Key Fob. You will 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 reprogrammed using the OBDII port with the right diagnostic tools.
