Transponder Chips

Transponder chips are likely to be found in vehicles manufactured within the past 20 years. It's a tiny plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the ignition barrel. This allows the vehicle's computer system to determine if 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 altering the key. The chip inside the car key verifies that the owner is the one who owns the vehicle. This will help reduce car theft.

Transponder keys resemble regular keys made of metal, but with caps made of plastic. The chip is inside the plastic portion of the keys. There are various cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the Car keys cut And programmed's computer detects this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine, and will alert you with flashing lights and a siren. This is designed to discourage people from attempting to hack into the vehicle, but it isn't a foolproof security measure. A skilled and skilled criminal could still evade this system by using a specific device that blocks the signal.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely, or making noises to aid in finding a car in a parking space keys of today can also activate a heated steering wheel, or roll down all windows with a single button push. Many of these extra features may seem convenient, but they can also make it harder for you to keep the keys to your car.

Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located within the middle of the key. The signal is encrypted to stop others from stealing or modifying the signal.

Keyfobs can be programmed in different ways based on the model and brand of your car. It is possible to do this yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.

When you press the button on a key fob the microchip sends an indication to the receiver in the vehicle that it is paired. The receiver then compares the data with the 'allowed signals' that are stored in the key fob and then it opens or closes the car's door. If the information does not match the fob's information, the car won't be allowed to operate.

After the car has been connected to a specific fob, it will only accept signals from the device. Other fobs won't work with the car, even though they look like. This is to safeguard the integrity of the car's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.

The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security skills that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by customers without the need of dealers.
