The key may not function properly or it may not even start the car at all. This is because the key hasn't yet been programmed into the car's system. This can be costly. It is best to have two keys that are compatible for the modern automobile so that you can program the replacement key if required.

A keyprogrammer can reprogram a transponder chip on a new mechanical key or key fob. It can also clone the data of an existing key in order to create duplicates. These are handheld devices that connect to a car key programer's On Board Diagnostics (OBD port). They have diagnostic software that enables them to communicate with computers as well as an interface that works bidirectionally with the immobilizer system.

There are a variety of keyprogrammers on the market. They are available in a variety of shapes, sizes and colors.

These are cheaper than going to a dealer however, they're expensive. Before you purchase one make sure you research the seller. Some are not reliable and could cause damage to your vehicle.

Transponder Chips

If your car was manufactured within the past 20 years, it is likely that it has a transponder inside of it. It's a tiny plastic piece inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the right one for the car you have.

This is what stops doing hot-wiring or altering the ignition system of your vehicle to start it. The chip inside the car key ensures that the owner is the person who is the owner of the vehicle. This can help to reduce car theft.

Transponder keys look like regular metal keys but have a plastic cap. The chip is housed within the plastic part of the key and there are different cuts that can be found on these keys: a standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.

A circuit inside the induction coil will emit signals when the transponder is inserted into an ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer inside the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.

If the vehicle does not recognize the transponder signal as being the correct one, it will stop the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is designed to deter people from trying to alter the vehicle, but it is not a foolproof security measure. A skilled and committed thief could still be able to get around this system using a special device to intercept the signal.

It is evident that the transponder is an excellent option. This is something that all car owners should consider if they are looking to safeguard their investment and minimize the risk of theft.

Key Fobs

Key fobs today can be more than just a way to lock and unlock doors. They can also start your vehicle remotely, emit chirping sounds to help locate cars, or turn on the heated steering wheel. These extra features could make it difficult to find your car keys.

Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are sent by a small antenna within the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and retransmitting the signal.

There are many ways to program a key fob based on the make and model. You may be able to do it yourself, but the majority of newer cars require that you visit a locksmith shop or a professional to program a replacement or additional fob.

When you press the button on a key fob, the microchip transmits an indication to the receiver inside the vehicle that it is paired. The receiver then compares this information with the 'allowed' signals stored in the fob and then either opens or closes the door. If the information doesn't match an chirping sound is heard and the car isn't allowed to function.

Once the car is linked with a particular fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even if they appear similar. This protects the integrity of the computer system of the car and blocks unauthorized key fobs gaining control over it.

Most newer car dealerships will only accept cars that have original fobs, or genuine replacements offered by the manufacturer. It is because the only place that has the knowledge to create an appropriate replacement fob is the service department of a dealer. Some fobs from the aftermarket, especially those for older models that have less sophisticated systems, can be programmed without the need for a dealer.
