To function properly, these cars require that a transponder chip-integrated key be programmed to the vehicle by a professional locksmith or mechanic/car dealer.

These tools are not generally accessible to the general public and are only used by professionals. This type of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a significant amount of time.

Other kinds of key programming can be done by anyone. They are accomplished using the onboard diagnostic port, which is accessible by a specific tool for key fob programming.

Key Programmers

Modern cars require a key-programming process to start the vehicle's system and start the car. In many cases, the key must be programmed by the dealer or an auto locksmith. This is because the key could not function properly, or it will not start the vehicle at all. This is because the new key hasn't been programmed to the automobile's system - and this can be very costly. This is why it's a good idea to always have two keys working for modern vehicles and have the replacement key programmed if needed.

A keyprogrammer can reprogram the transponder chip on the new mechanical key or key fob. It is also able to copy the data of an existing key, allowing duplicates to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.

Some are designed for specific kinds of vehicles, and they can even offer advanced diagnostics for the vehicle's electronic systems.

If you want to program an entirely new key for your vehicle, refer to the owner's manual for instructions on how. Some manufacturers use proprietary technology that ensures the dealership is the only entity able to create new keys. However, other manufacturers make it simple for anyone to do it on their own.

They are less expensive than going to a dealership but they aren't expensive. Make sure you investigate the seller prior to purchasing one. Some aren't reliable and could damage your car.

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 inside the head of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.

When activated by an electro-magnetic field the chip emits a low-level signal. This signal then gets taken up by the antenna that is positioned around the ignition barrel of your car keys programmed. The computer system of the vehicle will then confirm that the chip in the key's transponder is the right one for your car.

This stops the vehicle from being started through hot-wiring, or by altering the key. The chip inside the key confirms that the owner is the one who owns the vehicle. This helps to prevent the possibility of theft from your vehicle.

Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip is contained in the plastic portion of the key, and there are different kinds of cuts available on the keys: a standard cut, a laser cut and program car key (also called a sidewinder key) or Ford Tibbe key.

When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is received by the chip which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.

If the vehicle doesn't recognize the transponder signal as being the correct one, it will stop the engine from running and will alert you by flashing its lights and sounding siren. This is designed to discourage people from attempting to hack into the vehicle, however it isn't a foolproof security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that intercepts the signal.

You can see that the transponder is a good option. Every car owner should take this into consideration when they want to safeguard their investment and reduce 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 keys of today can also switch on a heated steering wheel, or roll down all of the windows with a single push. A lot of these features may seem convenient, but they can also make it more difficult to keep the track of your car keys.

Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted via an antenna that is located in the middle of the key. The communication is encrypted, which helps stop others from stealing and re-transmitting the signal.

There are several ways to program a key fob, based on the vehicle's model and make. You may be able to do it yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or additional fob.

When you press the button on your key fob it transmits a code to the car's receiver it is paired with. The receiver then compares the data with the permitted signals stored in the key fob, and then opens or locks the car door. If the data does not match the signals, the car will not be allowed to run.

When a car is connected with a specific fob it will only receive signals from that device. Other fobs will not work with the car, even if they look similar. This is to safeguard the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.

The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security expertise that can only be found in the dealer service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by the consumer without the need for an authorized dealer.
