Key Programmers
Modern cars often require a key programming procedure to set up the car's system and allow the car to start. In some instances the key will have to be programmed by an auto locksmith or dealer. This is because the key might not function properly, or it will not start the car in any way. This is because the new key hasn't been programmed to the car's system, and this could be quite costly. It's best to have two keys that work for the modern automobile so that you can program the replacement key whenever required.
A keyprogrammer is a tool that recodes the transponder chip into the form of a new key fob or mechanical key. It can also clone information from an existing key to make duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers. They also have a bidirectional user interface for working with an immobilizer system.
There are a variety of keyprogrammers available on the market. They come in all sizes, shapes and colors. Certain keyprogrammers are affordable while others could cost thousands of dollars. Some are made for specific automobiles and provide advanced diagnostics of the vehicle's electronic system.
Consult your owner's guide to learn how to program keys for your vehicle. Some manufacturers use proprietary technology that ensures the dealership is the sole entity that can create new keys, however other manufacturers make it fairly easy for anyone to do it themselves.
If you are unable to program a new key by yourself or request the dealer to program it for you, however this can be expensive. You can also buy a keyprogrammer on the internet. They're less expensive than going to the dealership, but they're still expensive. Be sure to investigate the seller prior to purchasing one - some are not reliable and can damage your vehicle.
Transponder Chips
If your car was manufactured in the last 20 years, then it has a transponder inside of it. It's a tiny plastic piece in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When activated by an electro-magnetic field, the chip emits a low level signal. The signal is taken up by an antenna that is attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip inside the key is the right one for your particular car.
This stops the vehicle from starting by hot-wiring, or by tampering. The chip inside the key ensures that the owner is the person who is the owner of the vehicle. This can reduce car theft.
Transponder keys look like regular keys made of metal but have caps made of plastic. The chip is housed in 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 Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will then get taken up by the chip and cause it to transmit a signal to the car. If the computer in the car detects the signal as valid it will turn off the car immobilizer to allow the engine start.
If the car doesn't recognize the transponder as being the proper signal, it will not start the engine, and will warn you with flashing lights and an alarm. This feature is intended to deter people from trying to tamper with the vehicle, but it is not a foolproof security measure. A skilled and determined criminal could still be able to get around this system using a device that can intercept the signal.
As you can see there are quite number of benefits to having transponder keys. This is something that all vehicle owners should consider if they are looking to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the car from a distance, make chirping sounds to help locate a car, or switch on the heated steering wheel. These additional features can make it difficult to find your car keys.
Key fobs are able to communicate with each with the car via radio frequencies that are transmitted through a small antenna located in the middle of the key. The transmission is encrypted, which helps stop others from stealing and re-transmitting the signal.
You can program a keyfob in different ways based on the model and make of your vehicle. It is possible to do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip sends a signal to the receiver in the vehicle with which it is linked. The receiver compares the information with the permitted signals stored on the key fob and then it opens or closes the car 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 particular fob, it will only receive signals from that device. Other fobs will not work with the car, despite the fact that they look similar. This protects the integrity of the computer system in the car and blocks the use of unauthorized key fobs to gain control over it.
Most dealerships with newer cars will only work with vehicles 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's service department. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems can be programmed by the consumer without the need of an authorized dealer.
