This is because the key hasn't yet been programmed into the vehicle's system. This can be expensive. It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key if needed.

Keyprogrammers are devices that can recode the transponder chip into the form of a new mechanical or key fob key. It is also able to copy data from an existing key to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with the computer and also provide an interface that works bidirectionally with the immobilizer system.

Transponder Chips

If your car was manufactured within the past 20 years, then it has a transponder inside of it. It's a tiny plastic piece inside the head of your key that contains an RFID (Radio Frequency Identification) chip with an individual code for your specific 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 attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder chip in the key is the right one for your specific vehicle.

This stops the vehicle from being started by either hot-wiring or by manipulating. The chip in the key also verifies that you are the legal owner of the vehicle. This can reduce car theft.

Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip is inside the plastic portion of the keys. There are several different cuts such as a standard cut laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is taken up by the chip, which sends a signal to the vehicle. If the onboard car computer recognizes this signal as being the correct one, it will disable the immobilizer on the vehicle and allow the engine to begin.

If the car does not recognize the transponder signal as being the correct one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This system is designed to deter people from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined criminal might be able get around this system using a device that can detect the signal.

As you can see there are quite a number of benefits to having transponder keys. This is something that all car owners should consider if they are looking to safeguard their investment and decrease the chance of theft.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also turn on the 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 locate your car keys.

Key fobs communicate with each with the car via radio frequencies that are transmitted by an antenna in the middle of the key. This communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.

Keyfobs can be programmed in various ways based on the make and model of your car. 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 an additional fob.

When you hit the button on a key fob it transmits a code to the car's radio that it is paired with. The receiver compared this information with the signals that are allowed on the fob and either opens or locks the door. If the data doesn't match an chirping sound is heard and the car isn't permitted to operate.

Once the car is associated with a particular fob, it only accepts signals from that device. In turn, other fobs will not work with the vehicle even if they look the same. This helps to protect the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control of the vehicle.

Most newer car dealerships will only deal with vehicles that have original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the knowledge to create a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by consumers without the need for an authorized dealer.
