Key Programmers
Modern automobiles require a key-programming method to initialize their vehicle's systems and to start the car. In a number of cases the key needs to be programmed by the dealer or auto locksmith. This is because the key may not function properly or start the car at all. The reason for this is that the new key hasn't been programmed to the automobile's system, and this could be very costly. This is why it's a good idea to always have two working keys for a modern automobile and to have the replacement key programmed if needed.
A keyprogrammer is a device that recodes the transponder chip into a new key fob or mechanical key. It also can clone information from an existing key in order to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with a computer. They also feature a bidirectional user interface to work with an immobilizer system.
There are a number of various kinds of keyprogrammers that are available and they come in all sizes and shapes. Some are affordable and others are advanced and could cost thousands of dollars. Certain models are specifically designed for certain types of vehicles and can offer advanced diagnostics for the car's electronic systems.
If you're interested in programming a new key to your vehicle, refer to the owner's manual for instructions on how to do it. Certain manufacturers have proprietary software that only permits dealers to make new keys. Other manufacturers make it simple for anyone to do.
If you are not able to program the new key yourself and you are unable to do it, then request your dealer to do it, however it will be very costly. You can also buy a keyprogrammer from the internet. They're less expensive than going to a dealer however they're not cheap. Make sure you look up the seller before buying one - some are not reliable and could harm your car.
Transponder Chips
If your car was built within the past 20 years, then it contains a transponder chip within of it. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. This signal is then received by a specific antenna attached to the barrel of ignition. This allows the vehicle's computer system to verify that the transponder chip in the key is the correct one for your particular car.
This prevents the vehicle from starting by either hot-wiring or by altering the key. The chip in the key also verifies that you are the genuine owner of the vehicle. This can help to reduce car theft.
Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip is contained within the plastic part of the keys. There are various cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and the Ford Tibbe.
A circuit within the induction coil will emit an electrical signal when the transponder is inserted into an ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal to the car. If the computer onboard the car detects the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as the correct signal, it will not start the engine, and will warn you with flashing lights and an alarm. This function is designed to discourage individuals from tampering with the vehicle. However, it is not an unbreakable security measure. A skilled and determined thief could still evade this system with a specially designed device that intercepts the signal.
It is evident that a transponder is a great option. This is something that all car owners should consider if they want to protect their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making sound chirps to help locate a car in a parking space Key fobs today can also activate a heated steering wheel, or roll down all of the windows with a single button press. These extra features can make it difficult for you to find your car keys.
Key fobs utilize radio frequencies to communicate with each other and with the car. The frequencies are transmitted by a small antenna within the middle of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal.
You can program a keyfob in different ways based on the make and model of your car. Some cars allow you to do this yourself. However, most newer models require you to visit an expert locksmith or dealer to program a new key fob or additional one.
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 'allowed signals' that are stored in the key fob and then locks or opens the car's door. If the information does not match, the car will not be allowed to drive.
Once the car is connected to a specific fob, it only accepts signals from that device. This means that other fobs won't work with the vehicle even though they have the same appearance. 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 cars with original fobs or genuine replacements that are 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. Some fobs from the aftermarket, especially ones for older models with less advanced systems, can be programmed without the need for a dealer.
