Transponder Chips

If your car is made within the past 20 years, chances are it has a transponder inside of it. This is the little 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 electro-magnetic field the chip emits a low level signal. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your vehicle. The computer system in the vehicle will then confirm that the chip in the key's transponder is the correct one for your vehicle.

This is the reason why hot-wiring or tampering with the ignition system of your vehicle to turn it on. The chip in the key also verifies that you are the legal owner of the vehicle. This helps to prevent car theft.

Transponder keys resemble regular metal keys, but with a plastic cap. The chip itself is housed in the plastic portion of the key, and there are a few different cuts that can be found on these keys: a regular standard cut and program car key (pop over to these guys) laser cut (also known as a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer onboard the car detects 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 a valid signal, it won't start the engine and will notify you via flashing lights and siren. This system is designed to deter those who would attempt to alter the vehicle. However it's not a foolproof measure of security. A skilled and skilled criminal could still evade this system using a special device that blocks the signal.

You can see that the transponder is a good option. Every car owner should take this into consideration when they want to safeguard their investment and decrease the risk of theft.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also start your vehicle remotely, make chirping noises to aid in finding cars, or turn on the heated steering wheel. These extra features can make it difficult for you to find your car keys.

Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are transmitted by a small antenna inside the middle of the key. The transmission is encrypted, which helps to keep others from stealing and re-transmitting the signal.

Keyfobs can be programmed in a variety of ways depending on the model and make of your car. You may be able to do it yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.

When you press a key fob's button it transmits an encoded code to the car's receiver that it is linked to. The receiver then compares this information with the 'allowed' signals on the fob and either opens or locks the door. If the information isn't in line, a chirping sound is heard and the car isn't able to operate.

After the car has been connected to a specific fob, it can only receive signals from that device. Other fobs won't work with the car, even though they appear similar. This helps to protect the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.

The majority of newer dealerships will only accept cars with original fobs, or genuine replacements supplied by the manufacturer. The reason for this is that the only place with the knowledge to create an appropriate replacement fob is the service department of the dealer. Some aftermarket fobs, usually those for older models that have less sophisticated systems can be programmed without the need for a dealership.
