Before you try to program your key fob by yourself, there are a few points you must be aware of. First, the procedure will differ between different automobile models.

Most modern cars have 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 make your car more comfortable to drive, and it can help you feel more secure. It lets you open doors and start the engine without having to look for keys. The system utilizes radio frequencies to connect the key fobs to the car's receiver. The process is simple and doesn't require any special equipment or prior knowledge.

When you press a button on your key fob, it sends an encrypted 40-bit code to a receiver in your vehicle. The receiver matches the code with a function number that tells it what action to take, like opening the doors or lowering the windows. The system is also designed to block others from using the key fob as a way to open your car, since every transmitter has a unique code.

Modern cars feature systems that automatically lock the vehicle after you have walked away from it. This could be beneficial if you tend to forget things or are worried about leaving your vehicle unattended. These systems do not come without their weaknesses. For instance, criminals could hack into these systems.

There are a few issues that can cause your keyless entry system and remote starter to not work properly. A dead battery inside your fob is the most common problem. You can replace the battery in case this is the cause. If this fails to fix the issue, you might require your fob to be changed to a different program.

Keyless Start System

With this technology, drivers can start their engines without having insert the mechanical key. The fob instead transmits an access key to the console, which unlocks a series of electrical switches, and then starts the engine. Once the engine is running at a certain speed, a button on fob can be pressed to turn off the motor off.

The system has safeguards that prevent the car from starting unintentionally in gear when there is no one at the steering wheel. Its computer monitors to make sure that the transmission is in park and the brake pedal is turned down before allowing the engine to start and can be set to require a specific sequence of press-button presses before the motor starts to run.

As with other modern smart keys like the suzuki swift key fob key fob, it's a wireless device that communicates with the car via radio frequency. The transmitter is built into the fob and its signal is picked up by antennas on both sides of the vehicle. These antennas are similar to ones used by the door locks and enable the car to sense that the fob is within its range. Once the receivers sense the signal, they will disable the immobilizer, allowing the engine to rotate, just as a normal key would.

Keyless Remote Control

If your key-fob doesn't work, it may be due to physical issues, like damaged battery connector contacts or buttons. It could be a software issue that requires reconfiguring. Simple tests with a multimeter or voltmeter will confirm that the battery is still in good condition and able to run the microprocessor that is in the remote.

The latest key fobs communicate with vehicle computer through RFID (radio frequency identification). They transmit a digital identification code, and the car computer saves this code to ensure that the key fob can unlock and start the car.

The key fobs transmit a signal at the same frequency as the cell phone. This technology can be used to remotely turn on vehicle systems, such as lift gates that power up or even start the engine of a car from outside. Fobs can also sound an attractive blare to frighten away thieves and other unwanted guests.

Batteries are by far the most frequent cause of the fob's key not working. If this is the case, changing the fob's programming is done by following the steps below.

Immobilizer

Based on the name, the Immobilizer stops the engine from running without a key fob. The system uses LF (low-frequency 125 KHz) transmitting antennas which are activated when the key fob is press or its handle is pulled. The key fob's transponder chip sends its ID back to the vehicle. The module that has information about the vehicle's identity checks the ID of the key fob with 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 article, security researcher Bokslag was able to hack three popular brands' immobilizers within a matter of ten seconds after receiving the keys.

The majority of older vehicles utilize a simpler, less reliable version of this system, that has a single permanent personal code and a constantly changing 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.

You'll require the 7-digit SKC (Skip Key Code), which is specific to your vehicle, in order to reprogramme a key. This number is available from the Dealership at the time of purchasing your new Key Fob. You'll also require the Workshop Code and Importer Number. The Immobilizer will not be affected by a battery disconnect, but you will need the right diagnostic tools to reprogram the Transponder ECU on the Key Fob.
