This is because the new key hasn't been programmed into the vehicle's system - and this can be quite costly. This is why it's a great idea to always have two working keys for a modern car and to have the replacement key programmed when necessary.

A keyprogrammer can recode the transponder chip of an entirely new mechanical key or key fob. It also can clone the data of an existing key to create duplicates. 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 computers. They also have a bidirectional interface to work with an immobilizer system.

Transponder Chips

If your car was built within the last 20 years, it is likely that it has a transponder chip inside of it. It's the tiny plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your vehicle.

When activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then received by a specific antenna that is attached to the ignition barrel. This allows the vehicle's computer system to determine if the transponder chip that is in the key is the correct one for your particular car.

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

Transponder keys appear like regular metal keys but they have a plastic cap. The chip is contained within the plastic portion of these keys. There are a variety of cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will then get taken up by the chip and cause it to send a signal back to the car. If the computer inside the car recognizes the signal as being correct it will turn off the car immobilizer to allow the engine start.

If the vehicle doesn't recognize the transponder signal as being the right one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This is designed to discourage people from attempting to alter the vehicle, but it's not a 100% security measure. A skilled and determined thief can still get around this system with a specially designed device that blocks the signal.

As you can see there are quite a number of advantages to having a transponder key. All car owners should consider this in order to safeguard their investment and minimize theft risk.

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 space keys of today can also activate the heated steering wheel or roll down all of the windows with just a single push. Many of these extra features may seem convenient but they could make it difficult for you to keep the track of your car keys.

Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are transmitted through a small antenna located in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and replicating the signal.

You can program a keyfob in various ways based on the model and make of your vehicle. It is possible to do this yourself, but the majority of newer automobiles require a dealer or professional locksmith to program a replacement or an additional fob.

When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver it is linked to. The receiver compared the information with the 'allowed signals' stored in the key fob and then opens or locks the car's doors. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.

When a car is connected with a specific fob it will only receive signals from that device. Other fobs won't work with the car keys programming near me, despite the fact that they appear like. This is to safeguard the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.

The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. It is because the only place that has the knowledge to create the replacement fob is the service department of a dealer. Certain aftermarket fobs, typically those from older models that have less sophisticated systems, can be programmed without the need for a dealer.
