There are certain things you must know before trying to program your own key fob. The first thing to know is that the method of programming will differ between car models.

Modern cars are usually equipped with an immobilizer. If you don't own the original key for the car, you'll not be able start it.

Keyless Entry System

A keyless entry system can make your car more comfortable to drive and improve security by allowing you to open doors and start the engine without having to reach for your 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 previous knowledge.

When you hit a button on the key fob, it broadcasts a 40-bit code to a receiver in your vehicle. The receiver matches the code to an operation code that tells it what to do, such as unlocking the doors or rolling down the windows. The system is also designed to prevent others from using your key fob to open your car, since each transmitter has its own unique code.

Modern cars come with systems that automatically lock your car when you've walked away from it, which is useful when you tend to forget things or worry about leaving your vehicle unattended. However, these systems have disadvantages, such as the possibility of thieves being able to hack into them.

There are several issues that can cause your keyless entry or remote starter to not perform properly. The most frequent cause is a dead or dying battery in your key fob. If this is the case, attempt replacing the battery in your fob. If this does nothing, you may have to have your fob programed.

Keyless Start System

With this technology, drivers can start their engines without having insert a mechanical key. Instead, the fob transmits an access code to the console that unlocks a number of electrical switches which activate the engine and allow it to start. After the engine has been started the fob's button can be pressed to shut it off.

The system is protected by safeguards that will stop the car from beginning accidentally in gear when there is no one at the steering wheel. The computer will verify that the transmission is in Park and that the brake pedal is pressed prior to allowing the car to start. It can also be set up to require an exact sequence of button presses.

Suzuki Alto Remote Key (Lodberg-Katz-2.Blogbright.Net)'s smart key fob, like other modern wireless devices connects to your car through radio frequency. The transmitter is built into the fob and its signal is picked up by antennas that are located inside and outside of the vehicle. These antennas, which are similar to those used for door locks, enable the car to detect when the fob is in of the range. Once the receivers detect a signal, they deactivate the immobilizer and allow the engine to operate like a regular key.

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 have an issue with software that requires the reprogramming. Simple tests using a multimeter or voltmeter will show if the battery is still charged and is able to run the microprocessor of the remote.

The newer key fobs are able to communicate with the vehicle computer through RFID (radio frequency identification). The key fob transmits a code and the car computer stores it so that the replacement key for suzuki sx4 is able to unlock and start your car.

Key fobs transmit a signal on the same frequency as the cell phone. This technology can be used to remotely trigger car systems, such as lift gates that can be powered or even start the engine of a car from outside. Fobs can also sound an alarming sound to scare off thieves and other unwanted guests.

Batteries are by far the most frequent cause of a key fob not working. Follow a few easy steps to reprogramme your fob if this is the case.

Immobilizer

As you might guess from the name, the Immobilizer prevents the engine of the vehicle from starting without a key fob. The system makes use of LF (low-frequency 125 KHz), transmitting antennas that are activated when the key fob is pressed or its handle pulled. The transponder chip inside the key fob then transmits the ID back to the vehicle. The module that knows the vehicle's identity compares the ID of the key fob against the BCM and If 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 study security researcher Bokslag was able to stealthily get into the Immobilizer on three vehicles belonging to popular brands within ten minutes of obtaining the keys.

Most older vehicles employ an older, less reliable version of this system, using a unique 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.

In order 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 available from the Dealership at the time of purchasing your new Key Fob. You will also need the Workshop Code and Importer Number. The Immobilizer system usually is not affected by a disconnect of the battery however the Transponder Electronic Control Unit on the Key Fob will need to be programmed via the OBDII port using the appropriate diagnostic tools.
