This is why it's a good idea to always have two keys that work for modern vehicles and to have the replacement key programmed if needed.
A keyprogrammer can reprogram the transponder chip of a new mechanical key or key fob. It can also clone the information from an existing key, allowing duplicates to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface that works with an immobilizer system.

Transponder Chips
If your car was built in the last 20 years, chances are it contains a transponder chip within of it. It's a small plastic piece inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When it is activated by an electromagnetic field the chip emits a low level signal. This signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your car. This allows the vehicle's computer system to verify that the transponder chip that is in the key is the correct one for your particular car.
This stops the vehicle from starting by either hot-wiring or by manipulating. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip itself is housed within the plastic part of the key and there are different kinds of cuts available on these keys: a regular cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil will emit a signal when the transponder is placed in the an ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the onboard car computer recognizes this signal as being the correct 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 the proper one, it will prevent the engine from running and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined thief can still get around this system by using a specific device that intercepts the signal.
As you can see there are quite number of benefits to having a transponder key. This is something that all car owners should think about if they are looking to safeguard their investment and decrease the chance of theft.
Key Fobs

These additional features can make it difficult for you to find your car keys.
Key fobs communicate with one other and the car using radio frequencies that are transmitted through a small antenna located in the center of the key. The communication is encrypted, which helps to keep others from stealing and retransmitting the signal.
You can program a keyfob in different ways based on the make and model of your car. Some cars allow you to do this by yourself. However, the majority of modern models require you to visit an expert locksmith or dealer in order to program a new key fob or an additional one.
When you press the button on a key fob the microchip sends signals to the receiver inside the vehicle with which it is linked. The receiver then compares the data with the permitted signals stored in the key fob and then it opens or closes the car's doors. If the information doesn't match the fob's information, the car won't be allowed to drive.
Once the car has been paired with a specific fob, it will only accept signals from that device. Other fobs won't work with the car, even though they look similar. This is to safeguard the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security skills that can only be found in the dealer service department. Some fobs from the aftermarket, especially ones for older models with less advanced systems can be programmed with out the need for a dealership.
