Key Programmers

Modern automobiles require a key-programming process to start the vehicle's system and then start the vehicle. In certain instances the key needs to be programmed by an auto locksmith or dealer. The key might not function correctly or will not start the vehicle at all. The reason for this is that the new key has not been programmed to the automobile's system, and this could be quite expensive. It is recommended to have two keys that are compatible with your current car so you can program the replacement key if needed.

Keyprogrammers can recode the transponder chip on an entirely new mechanical key or key fob. It is also able to copy the data of an existing key, allowing duplicates to be made. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with the computer as well as an interface that works bidirectionally with the immobilizer system.

Transponder Chips

Transponder chips are likely be found in vehicles manufactured within the last 20 years. It's the tiny plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the ignition barrel of your vehicle. The computer system of the vehicle will then confirm that the key's transponder chip is the correct one for your car.

This stops the vehicle from being started through either hot-wiring or by tampering. The chip inside the car key verifies that the owner is the person who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle.

Transponder keys appear like regular keys made of metal but they have caps made of plastic. The chip itself is housed in the plastic portion of the key and there are different cuts that can be found on the keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the car's computer detects this signal as the correct one, it will disable the immobilizer on the vehicle and allow the engine to start.

If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine and will alert you with flashing lights and an alarm. This feature is designed to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined thief could still bypass this system using a special device that intercepts the signal.

As you can see, there are quite a number of advantages to having a transponder key. This is something that all vehicle owners should consider if want to safeguard their investment and minimize the chance of theft.

Key Fobs

Key fobs today can offer more than locking and unlock doors. They can also turn on the car from a distance, make chirping sounds to aid in finding the car or switch on the heated steering wheel. A lot of these features may appear convenient, but they can also make it difficult for you to keep the keys to your car.

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

There are a few different ways to program a key fob, based on the vehicle's make and model. 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 an additional fob.

When you hit the button on a key fob the microchip inside sends a code to the car's radio that it is linked to. The receiver compares this information with the signals that are allowed inside the fob, and either opens or closes the door. If the data does not match the fob's information, the car won't be allowed to operate.


Once the car is connected to a specific fob, it will only accept signals from the device. As a result, other fobs will not work with the vehicle, even though they look the same. This is to safeguard the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control over the vehicle.

The majority of newer dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security expertise that is only available 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 consumers without the need for a dealership.
