This is why it's a great idea to have two keys working for modern vehicles, so you can get the replacement key programmed when necessary.

A keyprogrammer can recode the transponder chip of a new mechanical key or key fob. It is also able to copy information from an existing key in order to create duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with the computer, and they also have an interface that works bidirectionally with the immobilizer system.

Transponder Chips

Transponder chips are likely be found in cars manufactured within the past 20 years. It's a small piece of plastic on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.

When it is activated by an electro-magnetic field, the chip emits a low level signal. The signal is then absorbed by a special antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to verify that the transponder chip inside the key is the correct one for your particular car.

This is what prevents from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip in the car key ensures that the owner is the person who owns the vehicle. This will help reduce car theft.

Transponder keys appear like normal keys but have a plastic cap. The chip is contained within the plastic part of the key, and there are a few different types of cuts on these keys: a standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.

The circuit in the induction coil emits an electrical signal when the transponder is inserted into the ignition barrel. The signal is received by the chip which then transmits a signal to the vehicle. If the computer in the car recognizes the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.

If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and a siren. This is designed to deter people from trying to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still bypass this system using a special device that intercepts the signal.

You can see that a transponder is a great option. This is something that all car owners should consider if they want to protect their investment and minimize the risk of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely or making noises to aid in finding a car in a parking lot, today's key fobs can also switch on the heated steering wheel or roll down all of the windows with just a single push. These extra features can make it difficult to find your car keys.

Key fobs communicate with one with the car via radio frequencies that are transmitted via a small antenna located in the center of the key. This communication is encrypted to stop others from stealing or stealing the signal.

There are several ways to program a key fob, based on the vehicle's model and make. Certain models allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer to program a replacement key fob, or an alternative one.

When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver it is paired with. The receiver then compares this information to the 'allowed' signals stored on the fob and either opens or closes the door. If the data doesn't match an chirping sound is heard and the car isn't able to operate.

Once the car is linked with a specific fob, it will only receive signals from that device. This means that other fobs won't work with the vehicle even though they have the same appearance. This protects the integrity of the car's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.

The majority of newer dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise that can only be found in the dealer service department. However, some fobs from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need of dealers.
