Self-programming
As technology for cars has improved over time, the ignition keys have also evolved as well. The days of simple mechanical keys that you could purchase from a hardware shop for less than $10 are long gone. Newer models are equipped with computers that offer improved security against theft. To function correctly, these vehicles require that a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or car dealer/mechanic.
Professional locksmiths can perform various types of programming for keys for cars. Certain types are extremely complex and may require sophisticated tools. These tools are generally not accessible to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot time.
Other kinds of key programming can be carried out by anyone. These are usually done by using the onboard diagnostics port which can be accessed with the key-fob-programming device. This method can be performed by a locksmith who is trained with the help of an online guide or the vehicle's owner's manual.
Most professional locksmiths can program a new or replacement car key fob swiftly and precisely. This is the best option for car owners since they are able to provide a wide range of services. They can also offer a competitive price and peace of mind that the new key will work correctly.

This way, you can be sure that the new key is programmed for your vehicle and that it will work. Otherwise, you will need to pay the dealership for replacement keys and programming services.
Key Programmers
Modern automobiles require a key-programming method to start the vehicle's system and to start the car. In some instances the key needs to be set up by the dealer or an auto locksmith. The key might not function properly or 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 costly. This is why it's a great idea to always have two working keys for a modern car and have the replacement key programmed when required.
A keyprogrammer is a tool that can recode the transponder chip on the form of a new key fob or mechanical key. It also can clone data from an existing key in order to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with the computer, and they also have bidirectional interfaces to work with the immobilizer system.
There are automotive key programming of keyprogrammers available on the market. They come in all sizes, shapes and colors. Some are cheap while others are sophisticated and can cost thousands of dollars. Some are made for specific automobiles and offer advanced diagnostics of the car's electronic system.
If you're interested in programming an entirely new key for your vehicle, refer to the owner's manual to learn the procedure. Some manufacturers use proprietary software that only allows dealers to make new keys. Other manufacturers make it simple for anyone to do.
If you're unable to program a new key yourself, you can ask the dealership to do it for you, however it will cost a lot. You can also purchase an online keyprogrammer. These are cheaper than going to a dealer however they're not cheap. Before you purchase one do some research on the seller. Some are not reliable and may damage your vehicle.
Transponder Chips
If your car was manufactured within the past 20 years, chances are it has a transponder chip inside of it. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then received by a specific antenna attached to the barrel of ignition. This allows the car's computer system to verify that the transponder chip in the key is the correct one for your specific vehicle.
This prevents the vehicle from being started by either hot-wiring or by tampering. The chip inside the key also confirms that you are the genuine owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip itself is housed within the plastic part of the key, and there are different types of cuts on these keys: a regular standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
The circuit in the induction coil will emit an electrical signal when the transponder is inserted into the ignition barrel. The signal will be taken up by the chip and cause it to transmit a signal to the car. If the computer inside the car recognizes the signal as being correct, it will disable vehicle immobilizer to allow the engine start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and siren. This feature is designed to discourage people from attempting to alter the vehicle, but it isn't a foolproof security measure. A skilled and skilled criminal can still get around this system using a special device that detects the signal.
As you can see there are quite a number of benefits to having transponder keys. This is something that all vehicle owners should consider if are looking to safeguard their investment and reduce the chance of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start the car remotely, make chirping noises to help locate the car or turn on the heated steering wheel. These extra features could make it difficult to find your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted via a small antenna located in the center of the key. The communication is encrypted, which helps to keep others from stealing and re-transmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your car. It is possible to do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on your key fob it transmits an encoded code to the car's receiver it is linked to. The receiver compared this information to the signals that are allowed on the fob and either locks or opens the door. If the information does not match, the car will not be allowed to run.
When a car is connected 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 protects the integrity of the vehicle's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that is only available in the dealer service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by the consumer without the need for a dealership.
