Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the last 20 years. It's a small piece of plastic inside the head of your key that houses an 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-level signal. This signal is then absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. This allows the car's computer system to determine if the transponder chip that is in the key is the correct one for your specific vehicle.
This prevents the vehicle from starting by hot-wiring, or by altering the key. The chip in the key also confirms that you are the genuine owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular keys and have an outer layer of plastic. The chip is contained within the plastic portion of the keys. There are several different cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer in the car recognizes the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine, and will alert you with flashing lights and an alarm. This system is designed to deter those who would attempt to alter the vehicle. However, it is not an absolute security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that intercepts the signal.
As you can see there are quite a few advantages to getting a transponder key. All car owners must take this into consideration when they want to safeguard their investment and decrease theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate the car in a parking space keys of today can also turn on the heated steering wheel or roll down all windows with a single button push. These extra features can make it difficult for you to find your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted through an antenna in the middle of the key. The communication is encrypted, which helps to stop others from stealing and replicating the signal.
There are several ways to program a key fob depending on the vehicle's make and model. You may be able to do it yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob the microchip sends a signal to the receiver inside the car with which it is linked. The receiver compared this information to the 'allowed' signals on the fob and either locks or opens the door. If the data does not 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 the device. Other fobs won't work with the car, despite the fact that they look similar. This safeguards the integrity of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because the only place that has the knowledge to create the replacement fob is a dealer's service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by customers without the need of dealers.
