Self-programming

As technology for cars has improved over time, the ignition keys have evolved as well. The days of the simple mechanical keys you could buy from the hardware shop for less than $10 are long gone. The newer models have computer systems that are more secure against theft. To function properly, these cars require that a transponder chip key be programmed to the vehicle by a professional locksmith or a car dealer/mechanic.

There are many types of car keys programming that can be accomplished by locksmiths who are professionals. Some are extremely complicated and may require sophisticated tools. These tools are not generally available to the public and are utilized only by professionals. This kind of programming is referred to as EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.

Other kinds of programming car key s are a lot simpler and can be accomplished by the average person. They are typically done using the onboard diagnostics port, which is accessible with a special key-fob-programming tool.

You can be sure the new key will work and is compatible with your car. If not, you'll have to pay the dealer for replacement keys and programming services.

Key Programmers

Modern cars require a key-programming procedure to set up their systems and start the car. In a number of cases keys must be configured by the dealer or auto locksmith. The key may not work correctly or will not start the vehicle in any way. This is because the new key hasn't been programmed to the car's system - and this can be quite costly. It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key if needed.

A keyprogrammer can recode the transponder chip of an entirely new mechanical key or key fob. It is also able to clone information from an existing key, allowing duplicates to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that enables them to communicate with computers, and they also have a bidirectional interface for working with the immobilizer system.


There are a number of various kinds of keyprogrammers on the market, and they come in all shapes and sizes. Some are affordable, while others are very sophisticated and can cost thousands of dollars. Certain models are specifically designed for certain types of vehicles and can offer advanced diagnostics for the electronic systems of the car.

If you're looking to program the new key into your vehicle, refer to the owner's manual to learn how to do it. Certain manufacturers employ proprietary software that only permits the dealership to create new keys. Other manufacturers make it simple for anyone to do.

If you are unable to program a new key by yourself or ask the dealership to do it for you, however it will cost a lot. Another option is to purchase an online keyprogrammer. These are cheaper than going to a dealer however, they're expensive. Before buying one make sure you research the seller. Some aren't trustworthy and could damage your vehicle.

Transponder Chips

Transponder chips are likely to be found in cars manufactured within the last 20 years. It's the tiny 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 it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal then gets taken up by the antenna that is fitted around the ignition barrel of your car. The computer system in 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 starting by hot-wiring or tampering. The chip in the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.

Transponder keys look like regular keys made of metal, but with caps made of plastic. The chip itself is housed in the plastic portion of the key, and there are a few different types of cuts on these keys: a cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is received by the chip which sends a signal to the vehicle. If the car's computer recognizes this signal as being the correct one, it will turn off the immobilizer on the vehicle and allow the engine to begin.

If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However it's not an unbreakable security measure. A determined and skilled thief could still bypass this system with a specially designed device that blocks the signal.

As you can see, there are quite a number of benefits to having transponder keys. All car owners must take this into consideration if they wish to protect their investment and reduce the chance of theft.

Key Fobs

Key fobs today be more than just a way to lock and unlock doors. They can also start the vehicle remotely, make chirping noises to aid in finding the car or switch on the heated steering wheel. These additional features could make it difficult to find your car keys.

Key fobs communicate with one other and with the car through radio frequencies which are transmitted through a small antenna located in the center of the key. The communication is encrypted, which helps keep others from stealing and replicating the signal.

There are several ways to program a key fob depending on the vehicle's model and make. It is possible to do this yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or additional fob.

When you hit the button on a key fob the microchip inside sends an encoded code to the car's radio that it is linked to. The receiver then compares this information with the 'allowed' signals on the fob and either opens or closes the door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.

Once the car is paired with a specific fob it will only receive signals from that device. As a result, other fobs won't work with the vehicle even if they look the same. This helps to protect the integrity of the car's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.

The majority of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by customers without the need for an authorized dealer.
