Self-Programming

The ignition keys have changed along with the car technology. Gone are the days of simple mechanical keys that were made at a hardware store for under $10. 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 car dealer or mechanic for proper operation.

There are several types of car key programming that can be accomplished by professional locksmiths. Some are extremely complicated and may require sophisticated tools. These tools are usually not available to the general public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.

Other types of programming car keys are much simpler and can be accomplished by anyone who is able to.

You'll have to pay the dealer for programming and replacement keys if you don't.

Key Programmers

Modern automobiles require a key-programming process to set up their systems and start the car. In many cases keys must be programmed by the dealer or an auto locksmith. The key may not work properly or not start the vehicle in any way. This is because the key has not yet been programmed into the vehicle's system. This could be costly. It is recommended to have two keys that are compatible for the modern automobile so that you can program the replacement key if needed.

A keyprogrammer is a tool that can recode the transponder chip in the form of a new mechanical or key fob key. It can also clone the data from an existing key, allowing duplicates to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with the computer and also provide an interface that works bidirectionally with the immobilizer system.

There are many various kinds of keyprogrammers that are available and they are available in all sizes and shapes. Some are affordable while others are advanced and can cost thousands of dollars. Certain models are specifically designed for vehicles and can provide advanced diagnostics of the car's electronic system.


Refer to the owner's manual of your vehicle to learn how to program the key to your vehicle. Certain manufacturers employ proprietary technology that ensures the dealership is the only entity that can make new keys, however other manufacturers make it fairly easy for anyone to accomplish it on their own.

If you are unable to program a new key yourself or request the dealer to program it for you, however it will cost a lot. You can also buy an online keyprogrammer. They're less expensive than visiting a dealership, but still not cheap. Be sure to investigate the seller prior to purchasing one. Some aren't reliable and can damage your vehicle.

Transponder Chips

Transponder chips are likely to be found in cars manufactured in the last 20 years. This is the little plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.

The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is positioned around the ignition barrel of your car. The computer system of the vehicle will then confirm that the chip in the key's transponder is the right one for your vehicle.

This prevents the vehicle from starting by hot-wiring, or by tampering. The chip in the key also verifies that you are the legitimate owner of the vehicle. This helps to prevent car theft.

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

When automotive key programming is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer on the car recognizes this signal as being the correct one, it will shut down the vehicle immobilizer and allow the engine to start.

If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and will notify you via flashing lights and an alarm. This function is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and skilled criminal can still get around this system by using a specific device that intercepts the signal.

As you can see there are quite few advantages to getting transponder keys. This is something that all car owners should consider if they are looking to safeguard their investment and minimize the risk of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding the car in a parking space Key fobs today can also switch on a heated steering wheel or roll down all of the windows with a single button click. These extra features can make it difficult to find your car keys.

Key fobs communicate with each other and the car using radio frequencies which are transmitted via an antenna in the center of the key. The transmission is encrypted, which helps stop others from stealing and replicating the signal.

You can program a keyfob in a variety of ways depending on the make and model of your vehicle. Some cars allow you to do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob or additional one.

When you press the button on your key fob the microchip inside sends an informational code to the car's radio that it is paired with. The receiver compared the information with the 'allowed signals' stored in the key fob and then locks or opens the car's doors. If the information doesn't match, the car will not be allowed to operate.

After the car has been connected to a specific fob, it will only accept signals from the device. Other fobs will not work with the car, even though they look like. This is to safeguard the integrity of the car's computer system and prevent unauthorised key fobs from taking control of the vehicle.

Most newer car dealerships will only accept cars that have original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the experience to design the replacement fob is a dealer's service department. Some aftermarket fobs, usually those from older models that have less sophisticated systems, can be programmed without the need for a dealer.
