Modern models come with computers that are enhanced anti-theft protection. These cars require a transponder-chip integrated key to be programmed by a professional locksmith, mechanic or dealer in order to function properly.
Professional locksmiths are able to perform a variety of different types of programming for keys for cars. Some are complex and require sophisticated tools. These tools aren't generally accessible to the general public and are utilized only by professionals. This type of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.
Other types of programming car keys are much simpler and can be accomplished by the average person. They are typically done using the diagnostics port on the car, which is accessible with an instrument for programming keys. Locksmiths can carry out this method with the help of an online guide as well as the owner's manual.

You can be assured that the new key will work and is compatible with your car. In the event that it doesn't, you'll need to pay the dealership for replacement keys and programming services.
Key Programmers

The key may not function properly or not start the vehicle in any way. This is because the new key hasn't been programmed into the vehicle's system. This can be quite expensive. It is recommended to have two keys that work for the modern automobile so that you can program the replacement key whenever needed.
A keyprogrammer is a device that can recode the transponder chip into a new key fob or mechanical key. It is also able to copy information 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 enables them to communicate with computers as well as a bidirectional interface for working with the immobilizer system.
There are many different types of keyprogrammers available on the market and they are available in a variety of sizes and shapes. Some are affordable while others are sophisticated and can cost thousands of dollars. Certain models are specifically designed for certain kinds of vehicles and provide advanced diagnostics for the electronic systems of the car.

They are less expensive than going to a dealership however, they aren't expensive. Be sure to look up the seller before buying one - some are not reliable and could damage your vehicle.
Transponder Chips
Transponder chips are likely to be found in cars that were manufactured in the last 20 years. 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 vehicle.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is then received by a specific antenna attached to the barrel of ignition. The computer system in the vehicle can then verify that the transponder chip of the key is the right one for your car.
This is what prevents doing hot-wiring or altering the vehicle's ignition system to get it started. The chip inside the key confirms that the owner is the person who owns the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is inside the plastic part of these keys. There are a variety of cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
A circuit within the induction coil emits a signal when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car recognizes the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from tampering with the vehicle. However it isn't a foolproof measure of security. A determined and skilled thief could still evade this system using a special device that intercepts the signal.
As you can see there are quite few advantages to getting transponder keys. This is something that all car owners should think about if they want to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also start the vehicle remotely, emit chirping sounds to aid in finding the car or switch on the heated steering wheel. A lot of these features may seem convenient but they could make it harder for you to keep the keys to your car.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted via an antenna in the center of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
There are a few different ways to program a key fob, based on your vehicle's make and model. You may be able to do it yourself, but most newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.
When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver it is paired with. The receiver compares the information with the 'allowed signals' stored in the key fob and then opens or locks the car door. If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.
When a car is connected with a particular fob, it will only accept signals from that specific device. In turn, other fobs won't be able to work with the vehicle even though they appear similar. This protects the integrity of the computer system that runs the car and blocks the use of unauthorized key fobs to gain control over it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place that has the knowledge to create an appropriate replacement fob is the service department of a dealer. Certain aftermarket fobs, typically ones for older models with less sophisticated systems can be programmed with out the need for a dealer.
