This is because the key may not function correctly or start the vehicle at all. The reason for this is that the new key hasn't been programmed into the vehicle's system, and this could be quite expensive. This is why it's a great idea to always have two keys that work for a modern automobile and have the replacement key programmed when necessary.

A keyprogrammer can recode the transponder chip of the new mechanical key or key fob. It is also able to copy data 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 the computer and also provide a bidirectional interface for working with the immobilizer system.

There are a variety of keyprogrammers that are available on the market. They are available in a variety of shapes, sizes and colors.

Certain manufacturers have proprietary technology that makes sure that 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're unable to program the new key by yourself and you are unable to do it, then ask your dealer to do it, but it'll cost you a lot. Another option is to buy an online keyprogrammer. These are cheaper than going to a dealer, but they're still expensive. Make sure you research the seller before purchasing one - some are not reliable and could damage your vehicle.

Transponder Chips

If your car was built in the last 20 years, it is likely that it contains a transponder chip within of it. It's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.

The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is attached to the ignition barrel of your car. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the correct one for your vehicle.

This stops the vehicle from being started through hot-wiring, or by manipulating. The chip inside the key also confirms that you are the genuine owner of the vehicle. This will help reduce car theft.

Regular transponder keys are shaped like regular keys and have a plastic top. The chip itself is housed in the plastic portion of the key, and there are a few different cuts that can be found on these keys: a standard cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the computer onboard the car detects the signal as valid, it will disable vehicle immobilizer so that the engine can start.

If the car isn't able to recognize the transponder as the correct signal, it will not start the engine, and will notify you via flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief could still be able to bypass this system by using a device that can take over the signal.

As you can see, there are quite a number of advantages to having a transponder key. This is something that all car owners should think about if they want to protect their investment and decrease the risk of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate the car in a parking space, today's key fobs can also activate a heated steering wheel or roll down all of the windows with a single button push. A lot of these features might seem useful, but they can also make it more difficult to keep the keys to your car.

Key fobs are able to communicate with each other and the car using radio frequencies which are transmitted by a small antenna located in the center of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal.

You can program a keyfob in various ways based on the model and brand of your car. Some cars allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order for them program a replacement key fob or additional one.

When you press the button on a key fob, the microchip sends an indication to the receiver inside the vehicle with which it is paired. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car's doors. If the data does not match the fob's information, the car won't be allowed to run.

Once the car is associated with a particular fob, it can only receive signals from that device. Other fobs will not work with the car, despite the fact that they look identical. This protects the integrity of the vehicle's computer system and prevent unauthorised key fobs from taking control of the vehicle.

The majority of newer dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because the only place that has the knowledge to create the replacement fob is the service department of the dealer. 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.
