This is because the key may not work properly or start the car at all. The reason is because the new key hasn't been programmed into the vehicle's system. This can be quite costly. This is why it's a good idea to have two working keys for a modern car, so you can get the replacement key programmed if necessary.
Keyprogrammers can recode the transponder chip of the new mechanical key or key fob. It is also able to copy the data from an existing key and allow duplicate keys to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with computers.

Transponder Chips
If your car was built in the past 20 years, then it has a transponder inside of it. It's a tiny piece of plastic on the back of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your car. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the right one for the car you have.
This prevents the vehicle from being started through either hot-wiring or by tampering. The chip inside the key ensures that the owner is the person who owns the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular keys and have an outer layer of plastic. 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 cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will be taken up by the chip, causing it to send a signal back to the car. If the car's computer detects this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as being the proper one, it will stop the engine from starting and will alert you by flashing its lights and sounding siren. This function is designed to discourage individuals from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined thief could still be able to get around this system employing a device designed to take over the signal.
As you can see, there are quite a number of benefits to having transponder keys. Every car owner must take this into consideration in order to safeguard their investment and minimize theft risk.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find the car in a parking lot, today's key fobs can also turn on a heated steering wheel or open all windows with a single button push. A lot of these additional features might seem useful but they could make it harder for you to keep the keys to your car.
Key fobs use radio frequencies to communicate with each other and with the car. The frequencies are transmitted through a small antenna located within the middle of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal.
There are a few different ways to program a key fob based on the vehicle's model and make. You can sometimes do this yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends a code to the car's radio that it is linked to. The receiver compared this information with the 'allowed' signals on the fob and either opens or closes the door. If the information doesn't match, the car will not be allowed to run.
Once the car is connected to a specific fob, it can only receive signals from the device. As a result, other fobs won't work with the vehicle even though they have the same appearance. This protects the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. The reason for this is that the only place that has the expertise to prepare a replacement fob is in a dealer's service department. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by consumers without the need of a dealership.
