The key may not function properly or not start the car at all. This is because the key hasn't yet been programmed into the car's system. This can be costly. It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key if required.

Keyprogrammers are devices that recodes the transponder chip into the form of a new key fob or mechanical key. It can also clone data from an existing key in order to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with the computer as well as an interface that works bidirectionally with the immobilizer system.

There are a myriad of types of keyprogrammers that are available on the market. They come in all sizes, shapes and colors.

Transponder Chips

If your car was manufactured in the last 20 years, it is likely that it has a transponder chip inside of it. It's a tiny piece of plastic in the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.

The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is fitted around the ignition barrel of your car. The computer system in the vehicle can then verify that the transponder chip of the key is the right one for your car.

This is the reason why doing hot-wiring or altering the ignition system of your vehicle to turn it on. The chip in the car key confirms that the owner is the one who is the owner of the vehicle. This will help reduce car theft.

Transponder keys that are regular in shape like regular metal keys with an outer layer of plastic. The chip itself is housed inside the plastic portion of the key and there are a few different types of cuts on these keys: a regular cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.

The circuit in the induction coil will emit an electrical signal when the transponder is placed in the ignition barrel. The signal will be received by the chip, causing it to send a signal back to the car. If the computer inside the car detects the signal as correct it will turn off the vehicle immobilizer so that the engine can start.

If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine and notify you via flashing lights and a siren. This feature is intended to deter people from trying to hack into the vehicle, however it is not a foolproof security measure. A determined and skilled thief could still evade this system using a special device that detects the signal.

As you can see, there are quite a number of benefits to having a transponder key. This is something that all vehicle owners should consider if want to safeguard their investment and reduce the risk of theft.

Key Fobs

Key fobs today be more than just a way to lock and unlock doors. They can also start your car remotely, make chirping noises to aid in finding a car, or turn on the heated steering wheel. Many of these extra features may seem convenient however they could make it more difficult to keep track of your car keys.

Key fobs use radio frequencies to connect with one another and the car. The frequencies are transmitted by a small antenna inside the middle of the key. The signal is encrypted to stop others from intercepting or replicating the signal.

There are many ways to program a key fob, based on the vehicle's model and make. You can sometimes do this 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 linked to. The receiver compares the information with the 'allowed signals' stored in the key fob and then locks or opens the car's door. If the information doesn't match, the car will not be allowed to drive.

Once the car is linked with a particular fob, it will only accept signals from that device. In turn, other fobs won't work with the vehicle even though they look the same. This protects the integrity of the computer system in the car and blocks unauthorized key fobs gaining control of it.

The majority of newer dealerships will only deal with vehicles that have original fobs, or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the expertise to prepare the replacement fob is the service department of a dealer. Some aftermarket fobs, usually ones for older models with less sophisticated systems can be programmed without the need for a dealer.
