Key Programmers
Modern vehicles frequently require a key programming process to initialize the vehicle's system and allow the car to start. In some instances, the key will need to be programmed by an auto locksmith or dealer. This is because the key might not work properly or start the vehicle in any way. The reason is because the new key has not been programmed to the automobile's system - and this can be quite expensive. It is recommended to have two keys that work for the modern automobile so that you can program the replacement key when required.
Keyprogrammers are devices that recodes the transponder chip in the form of a new key fob or mechanical key. It can also clone data from an existing key to make duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with computers. They also have a bidirectional interface to work with an immobilizer system.
There are a number of various kinds of keyprogrammers that are available, and they come in all shapes and sizes. Some are inexpensive while others can cost thousands of dollar. Certain are designed for specific automobiles and offer advanced diagnostics of the vehicle's electronic system.
If you're interested in programming the new key into your vehicle, consult the owner's manual for instructions on how. Certain manufacturers employ proprietary software that allows only the dealership to create new keys. Other manufacturers make it simple for anyone to do.
If you're unable to program a new key on your own, you can ask the dealership to do it for you, but this can be expensive. You can also purchase a keyprogrammer on the internet. They are cheaper than visiting a dealership, but still not inexpensive. Before you purchase one do some research on the seller. Some aren't reliable and could cause damage to your vehicle.
Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. It's a tiny plastic piece on the back of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the barrel of ignition. The computer system of the vehicle can then verify that the transponder chip of the key is the correct one for your vehicle.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip in the car key ensures that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys appear like normal keys but have a plastic cap. The chip is housed within the plastic part of the key and there are a few different kinds of cuts available on the keys: a standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
The circuit in the induction coil emits signals when the transponder is inserted into the ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the car's computer recognizes this signal as being the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding a siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined thief may still be able to bypass this system by using a special device to take over the signal.
As you can see, there are quite a number of benefits to having a transponder key. Every car owner should take this into consideration in order to safeguard their investment and decrease theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate a car in a parking space Key fobs today can also switch on a heated steering wheel or roll down all of the windows with a single button push. A lot of these additional features might seem useful, but they can also make it more difficult to keep track of your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted by an antenna in the middle of the key. The transmission is encrypted, which helps stop others from stealing and retransmitting the signal.
There are a few different ways to program a key fob based on the vehicle's make and model. You can sometimes do this yourself, but the majority of newer vehicles require a dealer or professional locksmith to program a replacement or a second fob.
When you press a key fob's button it transmits an informational code to the car's radio that it is linked to. The receiver compares this information with the 'allowed' signals stored on the fob and either opens or closes the door. If the information doesn't match, a chirping sound is heard and the car isn't allowed to operate.
When a car is connected with a specific fob it will only receive signals from that specific device. Other fobs will not work with the car, even though they appear like. This ensures the security of the computer system in the car and prevents the use of unauthorized key fobs to gain control of it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place that has the knowledge to create the replacement fob is the service department of a dealer. Some fobs from the aftermarket, especially ones for older models that have less advanced systems can be programmed without the need for a dealer.
