This is why it's a good idea to have two keys working for modern vehicles, so you can get the replacement key programmed if necessary.

These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with the computer as well as bidirectional interfaces to work with the immobilizer system.

Transponder Chips

If your car was manufactured 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 that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.

When it is activated by an electromagnetic field, the chip emits a low level signal. The signal is then received by a specific antenna attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip in the key is the correct one for your particular car.

This prevents the vehicle from starting by hot-wiring or manipulating. The chip inside the key programming car also proves that you are the genuine owner of the vehicle. This helps to reduce the risk of theft from your car.

Transponder keys look like regular keys made of metal, but with caps made of plastic. The chip itself is housed within the plastic part of the key, and there are different cuts that can be found on these keys: a regular cut, a laser cut and program car keys (also called a sidewinder) or 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 will then get taken up by the chip and cause it to transmit a signal back to the car. If the car's computer detects this signal as 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 being the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding an alarm. This system is designed to deter individuals from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined thief may still be able to get around this system using a special device to detect the signal.

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

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also turn on the car remotely, make chirping noises to help locate the car, or switch on the heated steering wheel. These extra features could make it difficult to locate your car keys.

Key fobs communicate with each other and the car using radio frequencies which are transmitted by an antenna in the center of the key. This communication is encrypted, which helps to prevent others from intercepting and replicating the signal.

Keyfobs can be programmed in different ways based on the model and brand of your vehicle. It is possible to 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 receiver it is linked to. The receiver compares this information to the 'allowed' signals stored inside the fob, and either opens or locks the door. If the information doesn't match, the car will not be allowed to run.

Once the car is paired with a specific fob, it will only receive signals from that device. In turn, other fobs will not work with the vehicle even though they appear similar. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it.

The majority of newer dealerships will only accept cars that have original fobs, or genuine replacements sold by the manufacturer. This is because the only place with the expertise to prepare the replacement fob is the service department of the dealer. Certain aftermarket fobs, typically those for older models with less advanced systems can be programmed without the need for a dealer.
