Transponder Chips

Transponder chips are likely be found in vehicles manufactured in the last 20 years. This is a little piece of plastic on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.

When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then absorbed by a special antenna attached to the ignition barrel. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the correct one for the car you have.

This is what prevents hot-wiring or tampering with the ignition system of your vehicle to start it. The chip inside the car key ensures that the owner is the person who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip is housed in the plastic portion of the key, and there are a few different cuts that can be found on these keys: a standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.

A circuit inside the induction coil will emit an electrical signal when the transponder is placed in the ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer so that the engine can start.

If the car key cutting and programming isn't able to recognize the transponder as the correct signal, it won't start the engine and notify you via flashing lights and a siren. This is designed to deter people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and determined thief may still be able to get around this system using a special device to detect the signal.

As you can see there are quite number of benefits to having a transponder key. Every car owner must take this into consideration when they want to safeguard their investment and decrease the chance of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car keys cutting and programming remotely, or making sound chirps to help locate a car in a parking space Key fobs today can also turn on a heated steering wheel or roll down all of the windows with just a single push. These additional features could make it difficult to find your car keys.

Key fobs use radio frequencies to communicate with one another and the car. These frequencies are sent by a small antenna within the middle of the key. This communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.

You can program a keyfob in various ways based on the make and model of your car. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a replacement key fob, or an alternative one.

When you press a key fob's button the microchip inside sends an encoded code to the car's receiver it is linked to. The receiver compared this information with the 'allowed' signals stored inside the fob, and either opens or locks the door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.

Once the car is paired with a specific fob, it will only accept signals from that specific device. As a result, other fobs won't work with the vehicle even though they have the same appearance. This ensures the security of the computer system that runs the car and prevents unauthorised key fobs from taking control of it.

The majority of newer dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. The reason for this is that the only place that has the expertise to prepare the replacement fob is the service department of the dealer. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need of an authorized dealer.
