Transponder Chips

If your car was built in the past 20 years, chances are it has a transponder inside of it. It's a small plastic thing on the back of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.

When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is then absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. This allows the computer in your vehicle system to confirm that the transponder chip inside the key is the correct one for the car you have.

This stops the vehicle from being started through hot-wiring, or by tampering. The chip inside the car key verifies that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.

Transponder keys appear like regular metal keys, but with a plastic cap. The chip is contained within the plastic part of the key and there are different types of cuts on these keys: a cut laser cut (also called a sidewinder key), or a Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is received by the chip which sends a signal to the vehicle. If the computer onboard the car detects the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.

If the car doesn't recognize the transponder as being the proper signal, it won't start the engine and warn you with flashing lights and siren. This feature is designed to discourage those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A skilled and committed thief could still be able to get around this system using a special device to detect the signal.

As you can see, there are quite a number of advantages to having a transponder key. This is something that all vehicle owners should think about if they are looking to safeguard their investment and decrease the chance of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate a car in a parking lot Key fobs today can also activate a heated steering wheel or roll down all windows with a single push. These extra features can make it difficult to find your car keys.

Key fobs communicate with one other and with the car through radio frequencies which are transmitted by an antenna that is located in the middle of the key. This communication is encrypted to stop others from stealing or modifying the signal.

You can program car key a keyfob in a variety of ways depending on the make and model of your car. Some cars allow you to do it 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 it transmits an encoded code to the car's receiver it is linked to. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then locks or opens the car's doors. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.

When a car is connected with a specific fob it will only receive signals from that specific device. Other fobs will not work with the car, despite the fact that they appear similar. This protects the integrity of the car's computer system and prevent unauthorised key fobs from taking control over the vehicle.

The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security skills that can only be found in the dealer's service department. Some aftermarket fobs, usually those for older models that have less advanced systems can be programmed with out the need for a dealer.
