This is why it's a great idea to have two keys working for modern vehicles and have the replacement key programmed if necessary.
Keyprogrammers can recode the transponder chip of an entirely new mechanical key or key fob. It also can clone data 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 enables them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.

Transponder Chips
If your car is made within the past 20 years, chances are it contains a transponder chip within of it. It's the tiny piece of plastic in the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.
When it is activated by an electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by a special antenna attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip inside the key is the correct one for your particular car.
This prevents the vehicle from starting by hot-wiring, or by tampering. The chip inside the key also proves that you are the genuine owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip itself is housed within the plastic part of the key, and there are a few different cuts that can be found on these keys: a regular cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is received by the chip which sends a signal to the vehicle. If the car's computer recognizes this signal as being the correct one, it will turn off the vehicle immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will warn you with flashing lights and a siren. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not a foolproof measure of security. A skilled and determined thief could still evade this system by using a specific device that intercepts 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 are looking to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start the vehicle remotely, make chirping noises to aid in finding a car, or turn on the heated steering wheel. Many of these extra features may appear convenient however they could make it more difficult to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with each other and with the car. The frequencies are transmitted via a small antenna that is located within the middle of the key. This signal is encrypted to block other key fobs from stealing or modifying the signal.
There are a few different ways to program a key fob depending on the vehicle's make and model. Certain models allow you to do it yourself. However, most newer models require you to visit an expert locksmith or dealer for them program a replacement key fob, or an alternative one.
When you hit the button on a key fob, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver compares this information with the 'allowed' signals stored on the fob and either opens or closes the door. If the information does not match, the car will not be allowed to operate.
Once the car is paired with a specific fob, it will only accept signals from the device that is associated with it. In turn, other fobs won't work with the vehicle even if they look the same. This protects the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it.
Most newer car dealerships will only deal with vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security expertise which can only be obtained in the dealer service department. Certain aftermarket fobs, typically those for older models with less sophisticated systems can be programmed with out the need for a dealership.
