Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the past 20 years. It’s the tiny plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.

When it is activated by an electromagnetic field the chip emits a low level signal. The signal is received by a specific antenna that is attached to the barrel of ignition. The computer system of the vehicle can then verify that the key’s transponder chip is the correct one for your car.

This stops the vehicle from being started through hot-wiring, or by manipulating. The chip inside the 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.

Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip is contained within the plastic portion of these keys. There are various cuts: a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer on the car detects this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.

If the car key cutting and programming doesn’t recognize the transponder key programming as being the proper signal, it won’t start the engine and will warn you with flashing lights and a siren. This system is designed to deter those who would attempt to alter the vehicle. However it’s not an unbreakable security measure. A skilled and determined criminal could still be able to escape this security system by using a device that can take over the signal.

As you can see, there are quite a number of advantages to having transponder keys. This is something that all car owners should consider if want to protect their investment and decrease the chance of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find a car key cut and programed in a parking lot keys of today can also activate the heated steering wheel or roll down all windows with just a single press. These additional features can make it difficult to locate your car keys.

Key fobs communicate with each other and with the car through radio frequencies that are transmitted by a small antenna located in the center of the key. The signal is encrypted to stop others from stealing or modifying the signal.

There are a few different ways to program a key fob based on the vehicle’s make and model. You can sometimes do this yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or a second fob.

When you hit the button on a key fob, the microchip inside transmits a code to the car’s radio that it is linked to. The receiver then compares this information with the signals that are allowed inside the fob, and either locks or opens the door. If the information doesn’t match the fob’s information, the car won’t be allowed to run.

After the car has been paired with a specific fob, it will only accept signals from that device. In turn, other fobs will not work with the vehicle, even though they have the same appearance. This safeguards the integrity of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control over it.

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