This is because the key has not yet been programmed into the car's system. This could be costly. This is why it's a good idea to have two keys that work for a modern car and to have the replacement key programmed when necessary.

A keyprogrammer is a device that recodes the transponder chip in an entirely new mechanical or key fob key. It can also clone the information from an existing key which allows duplicate keys to be made. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with a computer. They also feature a bidirectional user interface to work with an immobilizer system.

Transponder Chips

If your car is made within the past 20 years, chances are it has a transponder inside of it. It's a small plastic thing inside the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.

When activated by an electro-magnetic field the chip emits a low level signal. The signal is then taken up by the antenna that is attached to the ignition barrel of your vehicle. This allows the car's computer system to confirm that the transponder chip that is in the key is the right one for your specific vehicle.

This prevents the vehicle from being started by hot-wiring, or by manipulating. The chip inside the car key ensures that the owner is the one who owns the vehicle. This helps to reduce the risk of theft from your car.

Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is housed in the plastic portion of the key and there are a few different cuts that can be found on the keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car detects the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.

If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine and will alert you with flashing lights and siren. This is designed to deter people from trying to tamper with the vehicle, however it is not a foolproof security measure. A skilled and determined criminal could still be able to get around this system using a special device to detect the signal.

It is evident that the transponder is an excellent option. This is something that all car owners should consider if they want to safeguard their investment and minimize the chance 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 windows with just a single press. These extra features could make it difficult to locate your car keys.

Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted through an antenna that is located in the center of the key. The communication is encrypted, which helps keep others from stealing and re-transmitting the signal.

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

When you hit the button on a key fob, the microchip inside transmits a code to the car's receiver it is linked to. The receiver compared this information to the signals that are allowed on the fob and either locks or opens the door. If the information does not match the fob's information, the car won't be allowed to drive.

Once the car has been connected to a specific fob, it only accepts signals from that device. In turn, other fobs won't work with the vehicle even if they appear similar. This is to safeguard 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 a car with original fobs or genuine replacements that are sold by the manufacturer. The reason for this is that the only place that has the experience to design a replacement fob is in a dealer's service department. Some aftermarket fobs, usually those for older models that have less sophisticated systems can be programmed with out the need for a dealer.
