Before you try to program your key fob yourself, there are a few things that you should be aware of. The first thing is that the process will vary between different automobile models.

The majority of modern cars have an immobilizer system. This means that if you don't have the original key and you don't have it, you won't be in a position 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 having to look for your keys. The system uses radio frequency to connect the key fobs to the car's receiver. It's a simple process and doesn't require any special equipment or experience.

When you press the button on your key fob the key fob sends a 40-bit signal to a device inside your vehicle. The receiver matches that code with an operation code that instructs it on what to do, like opening the doors or rolling down the windows. The system is designed to block other people from using your key fob to unlock your vehicle, since each transmitter has its own unique code.

Modern cars feature systems that automatically lock the vehicle after you've walked away from it. This is useful if you tend to forget things or are concerned about leaving your car unattended. These systems are not without their shortcomings. For instance, thieves are able to hack into these systems.

There are many issues that could cause the keyless entry system and remote starter not to work correctly. The most frequent cause is a dead battery on your key fob. You can replace the battery if this is the problem. If this fails will work, you may need to program your device.

Keyless Start System

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

The system also has security measures to stop the car from beginning in gear, or if someone is not near the steering column. Its computer checks to make sure that the transmission is in neutral and the brake pedal is pushed to the bottom before allowing the engine to begin and it can be set to require a certain number of button presses before the engine starts to run.

suzuki smart key's smart key fob, like other wireless devices of today connects to your car using 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 recognize when the fob is in range. If the receivers detect a signal, they deactivate the immobilizer, allowing the engine to operate like a regular key.

Keyless Remote Control

If your key fob doesn't work, it could be due to an issue with its physical components, like broken battery connector contacts or buttons. It could be a software problem that needs to be reprogrammed. Simple tests using an voltmeter or multimeter confirm that the battery is still in good condition and capable of running the microprocessor inside the remote.

Newer key fobs use RFID (radio-frequency identification) to communicate with the vehicle's computer. They transmit a digital identity code to the car computer saves this code to ensure that the key fob will be able to unlock and start the car.

Key fobs transmit signals at the same frequency as the cell phone. This technology can be used to remotely trigger car systems, such as lift gates that power up, or even start the engine of a vehicle from outside. Fobs emit a loud ring to stop thieves from entering the car.

Batteries are the most common reason for the fob's key not working. If this is the case, programming the fob is done by following the steps below.

Immobilizer

The Immobilizer, as you can imagine from its name, prevents the vehicle from beginning without the key fob. The system uses LF (low-frequency 125 kHz) transmitting antennas that are activated when the key fob is either pressed or its handle is pulled. The transponder chip on the key fob sends its ID back to the vehicle. The module that recognizes the vehicle's identity compares the key fob's ID with the one stored in the BCM, and if they 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 article, security researcher Bokslag was able to hack three popular Immobilizers for cars within ten seconds after obtaining keys.

The majority of older cars use a simpler, less reliable version of this system, using a unique permanent personal code and a 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.

To reprogram an authorized key, you need the 7 digit SKC (Skip Key Code) number for the specific vehicle you own. This number is obtained from the Dealership when you purchase a new Key Fob. You will also require the Workshop Code and Importer number. The Immobilizer will not be affected by a disconnected battery, but you will need the correct diagnostic tools in order to reprogram the Transponder's ECU in the Key Fob.
