How to Program Keys For Cars
Locksmiths or automotive specialists are usually the ones who re-program keys for cars. They could take your old key and then use a special tool to program a new key for your vehicle.
This involves the reprogramming of a blank chip on your replacement key to ensure that it is compatible with the current settings on your vehicle. Some manufacturers make it simple to do, while others require the assistance of a locksmith or dealer.
Self Programming
The ignition keys have developed along with the car technology. The days of simple mechanical keys that you could buy from the hardware shop for less than $10 have gone. Newer models are equipped with computers that offer improved security against theft. The cars require a transponder chip-integrated key to be programmed by a professional locksmith mechanic or dealer for proper operation.
There are many types of car keys programming that can be done by professional locksmiths. Some are complex and require sophisticated tools. These tools aren't generally accessible to the general public and are used only by professionals. This kind of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.
Other kinds of key programming can be carried out by anyone. They can be done by using the onboard diagnostic port, which is accessible by a specific tool for key fob programming. This method can be done by a locksmith who is trained with the help of an online guide or the car's owner's manual.
Most professional locksmiths can program a brand new or replacement car key fob fast and precisely. This is the ideal option for vehicle owners as they can provide a complete range of services. They can provide a competitive rate and the security of knowing that the replacement key is going to work.

This way, you can be certain that the new key has been programmed for your vehicle and that it will work. You'll have to pay the dealer for programming and replacement keys if you do not.
Key Programmers
Modern automobiles require a key-programming procedure to set up their 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 vehicle in any way. The reason is because the new key hasn't been programmed into the vehicle's system. This can be quite expensive. This is why it's a great idea to have two working keys for a modern car, so you can get the replacement key programmed when needed.
A keyprogrammer can reprogram a transponder chip on the new mechanical key or key fob. It also can clone the data of an existing key to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with computers. They also feature a bidirectional user interface to work with an immobilizer system.
There are a number of different types of keyprogrammers available that are available and they come in all shapes and sizes. Certain keyprogrammers are affordable while others may cost thousands of dollars. Certain are designed for specific automobiles and offer advanced diagnostics of the vehicle's electronic system.
If you want 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 allows dealers to make new keys. Other manufacturers make it easy for anyone to do.
If you're not able to program a new key by yourself or ask the dealership to program it for you, but it will cost a lot. Another option is to buy an online keyprogrammer. They are less expensive than visiting a dealership however, they aren't expensive. Be sure to research the seller before purchasing one - some are not reliable and can damage your car.

Transponder chips are likely be found in vehicles manufactured within the last 20 years. It's a small plastic thing inside the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
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 attached to the barrel that controls your ignition in your vehicle. The computer system of the vehicle can then verify that the chip in the key's transponder is the correct one for your car.
This prevents the vehicle from being started through hot-wiring or tampering. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip is contained inside the plastic portion of the key and there are a few different cuts that can be found on these keys: a regular standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal will be taken up by the chip, causing it to transmit a signal back to the car. If the computer in the car recognizes the signal as being correct it will turn off the vehicle immobilizer to allow the engine start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and will alert you with flashing lights and a siren. This feature is intended to deter people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A determined and skilled thief can still get around this system by using a specific device that blocks the signal.
As you can see there are quite number of advantages to having a transponder key. This is something that all vehicle owners should think about if they are looking to safeguard their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making noises to aid in finding the car in a parking space, today's key fobs can also activate the heated steering wheel or roll down all of the windows with just a single push. These extra features can make it difficult for you to locate your car keys.
Key fobs utilize radio frequencies to connect with one another and with the car. These frequencies are sent by a small antenna in the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal.
There are many ways to program a key fob, based on the vehicle's model and make. You may be able to do it yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on your key fob, the microchip inside transmits a code to the car's receiver that it is paired with. The receiver compared this information with the 'allowed' signals on the fob and either locks or opens the door. If the information doesn't match an chirping sound is heard and the car isn't allowed to operate.
Once the car has been connected to a specific fob, it only accepts signals from that device. In turn, other fobs will not work with the vehicle even if they appear similar. This ensures the security of the computer system that runs the car and prevents unauthorized key fobs gaining control over it.
Most dealerships with newer cars will only work with cars that have original fobs or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer service department. Some aftermarket fobs, usually those from older models that have less sophisticated systems, can be programmed without the need for a dealership.
