Transponder Chips

If your car was manufactured within the past 20 years, chances are it has a transponder chip inside of it. It's a tiny plastic piece inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.

When it is activated by an electro-magnetic field, the chip emits a low level signal. This signal then gets taken up by the antenna that is attached to the ignition barrel of your vehicle. This allows the vehicle's computer system to verify that the transponder chip that is in the key is the correct one for the car you have.

This is what stops doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip in the key also verifies that you are the genuine owner of the vehicle. This will help reduce car theft.

Transponder keys resemble regular metal keys, but with a plastic cap. The chip is inside the plastic part of the keys. There are several different cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the onboard car computer detects this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to begin.

If the vehicle doesn't recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This feature is intended to deter people from trying to hack into the vehicle, but it's not a 100% security measure. A determined and skilled thief could still evade this system by using a specific device that detects the signal.

As you can see there are quite few advantages to getting transponder keys. This is something that all vehicle owners should consider if want to protect their investment and minimize the risk of theft.

Key Fobs

Key fobs today can offer more than locking and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to aid in finding a cheap car key programming, or switch on the heated steering wheel. Many of these extra features may appear convenient but they could make it more difficult to keep the keys to your car.

Key fobs communicate with each other and with the car through radio frequencies which are transmitted through an antenna that is located in the middle of the key. This communication is encrypted to prevent others from intercepting or replicating the signal.

You can program a keyfob in different ways based on the model and make of your vehicle. You may be able to do it yourself, however most modern cars require that you visit a locksmith shop or a professional to program a replacement or a second fob.

When you press the button on a key fob the microchip transmits an indication to the receiver in the vehicle with which it is linked. The receiver compares the information with the 'allowed signals' stored on the key fob and then locks or opens the car door. If the data does not match, the car will not be allowed to drive.

After the car has been associated with a particular fob, it will only accept signals from the device. This means that other fobs will not work with the vehicle even though they appear similar. This safeguards the integrity of the computer system in the vehicle and stops unauthorized key fobs gaining control of it.

The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. The reason for this is that the only place that has the experience to design a replacement fob is in the service department of the dealer. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by customers without the need for dealers.
