This is why it's a great idea to have two keys that work for a modern automobile and have the replacement key programmed when necessary.

These are handheld devices connected to a car's On Board Diagnostics (OBD port). They have diagnostic software that allows them to communicate with the computer as well as a bidirectional interface for working with the immobilizer system.

Transponder Chips

If your car was built within the last 20 years, it is likely that it has a transponder inside of it. This is a little plastic thing in the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.

The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. The computer system of the vehicle will then confirm that the transponder chip of the key is the right one for your car.

This stops the vehicle from being started by either hot-wiring or by altering the key. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to prevent car theft.

Regular transponder keys are designed like regular metal keys with a plastic top. The chip itself is housed inside the plastic portion of the key and there are a few different types of cuts on these keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

The circuit in the induction coil will emit signals when the transponder is inserted into an ignition barrel. The signal will be absorbed by the chip, causing it to transmit a signal to the car. If the car's computer detects this signal as the right one, it will shut down the immobilizer on the vehicle and allow the engine to begin.

If the vehicle does not recognize the transponder signal as the proper one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This system is designed to deter individuals from tampering with the vehicle. However, it is not an absolute security measure. A determined and skilled thief could still evade this system by using a specific device that blocks the signal.

As you can see there are quite number of advantages to having a transponder key. Every car owner should consider this when they want to safeguard their investment and reduce the chance of theft.

Key Fobs

Key fobs today do more than just lock and unlock doors. They can also start the car remotely, make chirping noises to aid in finding the car, or turn on the heated steering wheel. These extra features can make it difficult to find your car keys.

Key fobs communicate with each other and with the car key programmer through radio frequencies which are transmitted by a small antenna located in the center of the key. The communication is encrypted, which helps to stop others from stealing and replicating the signal.

You can program a keyfob in various ways based on the make and model of your car. It is possible to do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.

When you press a key fob's button the microchip inside sends a code to the car's radio that it is linked to. The receiver then compares this information to the 'allowed' signals in the fob and then either opens or locks the door. If the information does not match the signals, the car will not be allowed to operate.

Once the car is paired with a specific fob, it will only receive signals from that device. Other fobs won't work with the car, even though they look similar. This protects the integrity of the computer system that runs the vehicle and stops unauthorised key fobs from taking control of it.

Most dealerships with newer cars will only accept cars that have original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the expertise to prepare a replacement fob is in the service department of a dealer. Some aftermarket fobs, usually those for older models with less advanced systems can be programmed without the need for a dealership.
