The latest models come with computer systems that are more secure against theft. These cars require a transponder-chip integrated key to be programmed by a professional locksmith mechanic or dealer in order to function properly.

There are many kinds of car key programming that can be done by locksmiths who are professionals. Certain types are more complex and require sophisticated tools. These tools are not available to the general public and are used only by professionals. This type of programming for car keys is known as EEPROM Programming and requires soldering, electronic knowledge, and a lot of time.

Other forms of programming for car keys are much simpler and can be accomplished by the average person. They are accomplished with the onboard diagnostic port, which is accessible via a tool specifically designed for key-fob programming.

Key Programmers

Modern cars require a key-programming method to initialize their vehicle's systems and then start the vehicle. In some cases the key needs to be programmed by an auto locksmith or a dealer. The key may not work correctly or will not start the car in any way. This is because the key has not yet been programmed into the car's system. This can be expensive. This is why it's a good idea to always have two keys that work for a modern car and have the replacement key programmed when needed.

Keyprogrammers can recode the transponder chip of an entirely new mechanical key or key fob. It can also clone the data of an existing key, allowing duplicates to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface to work with an immobilizer system.

There are a number of different types of keyprogrammers available on the market, and they come in all sizes and shapes.

Transponder Chips

If your car was manufactured in the last 20 years, then it contains a transponder chip within of it. It's the small piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.

When activated by an electro-magnetic field, the chip emits a low-level signal. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your vehicle. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.

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

Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is contained within the plastic part of the keys. There are a variety of cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will be received by the chip, causing it to transmit a signal back to the car. If the computer inside the car key programer detects the signal as correct it will turn off the car immobilizer so that the engine can start.

If the car doesn't recognize the transponder as the correct signal, it won't start the engine and warn you with flashing lights and an alarm. This feature is intended to deter people from trying to tamper with the vehicle, however it is not a foolproof security measure. A skilled and skilled criminal could still bypass this system using a special device that detects the signal.

As you can see there are quite few advantages to getting 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 do more than just lock and unlock doors. They can also start the vehicle remotely, make chirping noises to help locate cars or turn on the heated steering wheel. These extra features can make it difficult for you to locate your car keys.

Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted by an antenna in the center of the key. The transmission is encrypted, which helps prevent others from intercepting and re-transmitting the signal.

There are a few different ways to program a key fob based on the vehicle's model and make. Some cars allow you to do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a new key fob or an additional one.

When you press the button on a key fob, the microchip transmits signals to the receiver inside the car that it is paired. The receiver compares this information with the 'allowed' signals stored inside the fob, and either opens or locks the door. If the information isn't in line, a chirping sound is heard and the reprogram car keys isn't able to operate.

Once the car has been connected to a specific fob, it will only accept signals from that device. As a result, other fobs will not work with the vehicle even though they have the same appearance. This helps to protect 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 dealerships will only work with vehicles that have original fobs, or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the expertise to prepare the replacement fob is the service department of a dealer. However, some aftermarket fobs typically for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
