Transponder Chips
Transponder chips can be found in vehicles manufactured within the last 20 years. This is a little piece of plastic in the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When activated by an electro-magnetic field the chip emits a low-level signal. This signal is then amplified by the specific antenna that is fitted around the ignition barrel of your car. The computer system of the vehicle is then able to verify that the transponder chip of the key is the right one for your vehicle.
This prevents the vehicle from being started by hot-wiring, or by manipulating. The chip inside the car key confirms that the owner is the one who owns the vehicle. This can help to reduce car theft.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip is located inside the plastic part of the keys. There are various cuts: a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal will be absorbed by the chip and cause it to transmit a signal back to the car. If the computer in the car recognizes the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the vehicle does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding siren. This system is designed to deter those who would attempt to alter the vehicle. However it isn't an absolute security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that detects the signal.
As you can see there are quite few advantages to getting transponder keys. All car owners must take this into consideration when they want to safeguard their investment and minimize the risk of theft.

A lot of these features might seem useful however they could make it difficult for you to keep the track of your car keys.
Key fobs use radio frequencies to communicate with one another and the car. These frequencies are sent via a small antenna that is located within the middle of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal.
There are a few different ways to program a key fob, based on your vehicle's model and make. Some cars allow you to do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a new key fob, or an alternative one.
When you press the button on a key fob the microchip transmits an indication to the receiver inside the car with which it is linked. The receiver compares the information with the permitted signals stored on the key fob and then opens or locks the car door. If the information doesn't match an chirping sound is heard and the car isn't allowed to operate.
Once the car has been paired with a specific fob, it can only receive signals from the device. As a result, other fobs won't work with the vehicle even if they have the same appearance. This protects the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only accept vehicles that have original fobs, or genuine replacements sold 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 service department. Certain aftermarket fobs, typically those for older models with less advanced systems can be programmed without the need for a dealer.
