How to Program Keys For Cars
Automotive specialists or locksmiths are typically the ones who re-program car keys. They can make use of a specific program to program your new key using your old one.
The procedure involves reprogramming the chip in your replacement key to fit the current settings of your vehicle. Certain manufacturers make it simple, while other require an expert locksmith or dealer.
Self-Programming
As the technology of cars has advanced throughout the years, ignition keys have evolved as well. The days of basic mechanical keys you could buy from the hardware shop for less than $10 are gone. The latest models come with computers that have improved anti-theft security. To function properly, these cars require that a transponder chip key be programmed to the vehicle by a certified locksmith or mechanic/car dealer.
Professional locksmiths can carry out various kinds of programming for keys for cars. Certain types are extremely complex and may require advanced tools. These tools are not available to the general public and are used only by professionals. This kind of programming is referred to as EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.
Other kinds of programming car keys are much simpler and can be done by anyone who is able to. They are typically accomplished by using the onboard diagnostics port which is accessible with an instrument for programming keys. Locksmiths can execute this method with the assistance of a guide online and the owner's manual.
Professional locksmiths can program a new or replacement car key fob in a short time. This is the ideal option for vehicle owners as they can offer a full range of services. They can provide a competitive rate and the peace of mind knowing that the replacement key is guaranteed to work.
It is important to note that a lot of vehicles only accept a single key for their system. If you're looking to save money, it's a good idea to purchase an additional key fob that is functional and then have it programmed. You can be certain that the new key will work and is programmable for your vehicle. You will have to pay the dealer for programming and replacement keys if you do not.
Key Programmers
Modern cars often require a key programming process to initialize the vehicle's system and allow the car to start. In certain instances the key needs to be programmed by an auto locksmith or dealer. This is because the key might not function correctly, or it will not start the car in any way. The reason is because the new key has not been programmed to the automobile's system, and this could be quite costly. This is why it's a good idea to have two working keys for a modern car, so you can get the replacement key programmed if required.
Keyprogrammers are devices that can recode the transponder chip into an entirely new key fob or mechanical key. It is also able to copy the data of an existing key which allows duplicate keys to be made. 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 computers. They also feature a bidirectional user interface that works with an immobilizer system.
There are a number of different kinds of keyprogrammers on the market and they come in all sizes and shapes. Some are cheap, while others are very advanced and could cost thousands of dollars. Some are specifically designed for certain types of vehicles and can provide advanced diagnostics for your vehicle's electronic systems.
Refer to the owner's manual of your vehicle to learn how to program a key for your vehicle. Certain manufacturers have proprietary technology that guarantees that the dealership is the only entity that can make new keys. However, other manufacturers make it simple for anyone to do it themselves.
If you are not able to program the new key by yourself and you are unable to do it, then ask your dealer to do it, but it'll be very costly. Another option is to buy a keyprogrammer online. They're less expensive than going to a dealership but they aren't inexpensive. Before buying one do some research on the seller. Some aren't reliable and could cause damage to your vehicle.
Transponder Chips
If your car was manufactured in the past 20 years, then it has a transponder inside of it. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the transponder chip of the key is the right one for your vehicle.
This prevents the vehicle from being started through either hot-wiring or by altering the key. The chip in the key also verifies that you are the legitimate owner of the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip is housed inside the plastic portion of the key and there are a few different types of cuts on these keys: a standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil emits signals when the transponder is put into ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer on the car 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 does not recognize the transponder signal as being the right one, it will stop the engine from running and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage people from attempting to tamper with the vehicle, but it isn't a foolproof security measure. A determined and skilled thief could still evade this system by using a specific device that intercepts the signal.
As you can see there are quite number of benefits to having a transponder key. This is something that all car owners should consider if want to protect their investment and minimize the risk of theft.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start your vehicle remotely, emit chirping sounds to aid in finding cars, or switch on the heated steering wheel. These additional features could make it difficult to locate your car keys.
Key fobs make use of radio frequencies to communicate with each other and with the car. The frequencies are transmitted by a small antenna inside the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
Keyfobs can be programmed in different ways based on the model and make of your vehicle. Certain cars let you do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer for them program a replacement key fob or additional one.
When you press the button on a key fob the microchip sends a signal to the receiver inside the car with which it is paired. The receiver compared the information with the 'allowed signals' that are stored in the key fob and then it opens or closes the car's doors. If the information does not match, the car will not be allowed to operate.

Once the car has been associated with a particular fob, it will only accept signals from the device. Other fobs will not work with the car, even if they appear like. This ensures the security of the computer system of the car and prev ents unauthorised key fobs from taking control of it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills which can only be obtained 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 consumers without the need for a dealership.
