Suzuki Key Fob Programming

Before you attempt to program your key fob on your own, reprogrammed there are some points you must be aware of. The first is that the procedure can differ between different car models.

Modern cars are equipped with 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 can make your car more comfortable to drive in addition to increasing security by permitting you to open the doors and start the engine without reaching for your keys. The system uses radio frequencies to connect the key fobs with the car's receiver. The process is quite simple, and it does not require any special equipment or past experience.

When you hit a button on the key fob, it transmits an encrypted 40-bit code to a receiver in your vehicle. The receiver matches the code to a function code that tells it what to do, like opening the doors or opening the windows. The system is designed to keep others from using your key fob in order to unlock your car, as each transmitter has its unique code.

Modern cars are equipped with systems that automatically lock your car when you walk away. This can be useful for those who are prone to forgetting things, or if you are worried about leaving your car unattended. These systems do not come without their shortcomings. For example, thieves are able to hack into these systems.

There are many problems that could cause the keyless entry system as well as remote starter to not function properly. A dead battery inside your fob is the most frequent issue. You can replace the battery if it is the problem. If this does not fix the issue, you might need to have your device reprogrammed.

Keyless Start System

This technology allows drivers to start their engines without the need of an electronic key. The fob instead sends an access key to the console that unlocks a set electrical switches and starts the engine. Once the engine has begun, the fob's button can be pressed to turn it off.

The system also comes with security measures to stop the car from starting in gear, or when someone is not in the vicinity of the steering column. The computer will verify that the transmission is in Park and that the brake pedal is engaged prior to allowing the car's engine to start. It is also possible to be configured to require an exact sequence of button presses.

Suzuki's smart key fob like other wireless devices of the present communicates with your car through radio frequency. The transmitter is built into the fob, and the signal is picked up by antennas in and outside the vehicle. These antennas, like those used for door locks, allow the car to detect when the fob is within range. Once the receivers detect the signal, they will disable the immobilizer and let the engine turn over, just like the normal key would.

Keyless Remote Control

If your key fob doesn't function, it could be due to physical issues, like damaged battery connector contacts or button. It could also be an issue with the software, which requires reprogramming. Simple tests using an voltmeter or multimeter reveal if the battery fully charged and able to run the microprocessor that is in the remote.

The newer key fobs connect to the car computer using RFID (radio frequency identification). They transmit a digital identification code to the car computer stores this code so that the key fob will be able to unlock and start the car.

The key fobs transmit a signal at the same frequency as cellphones do. This technology can be used to remotely trigger automobile systems, like lift gates that can be powered or even start the engine of a car from outside. Fobs also can trigger an attention-grabbing blare to frighten away criminals and other undesirable guests.

The most common reason for a key fob to stop working is because the batteries need to be replaced. Follow these steps to reprogramme the fob if this is the situation.

Immobilizer

The Immobilizer, as one can guess from its name, prevents the vehicle from starting without a key fob. The system employs LF (low frequency of 125 kmhz) transmitting antennas inside and outside the vehicle that are activated by the key fob's button press or when its handle is pulled. The transponder chip on the key fob then transmits the ID back to the vehicle. The module that recognizes the vehicle's identity checks the key fob's ID with the one stored in the BCM If they 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 crack the Immobilizer in three cars by popular brands within ten second of getting the keys.

Most older vehicles use an older, less reliable version of this system, with a single permanent personal code, and a dynamic 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.

You'll require the 7-digit SKC (Skip Key Code), that is specific to your car, to reprogram a key. This number can be found by the dealer when you purchase your new Key Fob. You will also need the Workshop Code and Importer Number. The Immobilizer system won't be affected by a disconnected battery however, you will require the correct diagnostic tools to reprogram the Transponder ECU in the Key Fob.
