Transponder Chips

Transponder chips are likely to be found in vehicles manufactured in the last 20 years. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.

The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is attached to 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 right one for your specific vehicle.

This stops the vehicle from starting by hot-wiring or altering the key. The chip in the car key confirms that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.

Transponder keys resemble normal keys but have a plastic cap. The chip is contained within the plastic part of the key and there are a few different kinds of cuts available on the keys: a standard cut laser cut (also called a sidewinder) or Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out a signal. The signal is received by the chip which then transmits a signal the vehicle. If the car's computer recognizes this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to start.

If the car does not recognize the transponder signal as the correct one, it will keep the engine from running and will alert you by flashing its lights and sounding siren. This feature is designed to deter people from trying to hack into the vehicle, however it isn't a foolproof security measure. A skilled and committed thief might be able get around this system employing a device designed to detect the signal.

As you can see there are quite a few advantages to getting transponder keys. This is something that all vehicle owners should consider if are looking to safeguard their investment and decrease the chance of theft.

Key Fobs

In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find the car in a parking lot, today's key fobs can also turn on the heated steering wheel or open all windows with just a single press. These extra features can make it difficult to locate your car keys.

Key fobs communicate with one other and the car using radio frequencies that are transmitted through an antenna in the middle of the key. The transmission is encrypted, which helps to stop others from stealing and retransmitting the signal.

There are a few different ways to program a key fob, based on your vehicle's make and model. Certain models allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a new key fob or an additional one.

When you press the button on a key fob, the microchip transmits signals to the receiver inside the vehicle that it is paired. The receiver compared the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car's door. If the data does not match the fob's information, the car won't be allowed to drive.

When a car is connected with a specific fob it will only receive signals from the device that is associated with it. In turn, other fobs won't work with the vehicle, even though they look the same. This protects the integrity of the computer system in the car and blocks the use of unauthorized key fobs to gain control of it.

The majority of newer dealers will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because the only place that has the expertise to prepare the replacement fob is a dealer's service department. Certain aftermarket fobs, typically those for older models with less advanced systems, can be programmed without the need for a dealer.
