mobile car key programmer dealer/mechanic.
Professional locksmiths can carry out various kinds of programming for keys to cars. Certain types are more complex and require sophisticated tools. These tools are not accessible to the general public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.
Other forms of car key programming are much simpler and can be done by the average person.

The reason is because the new key hasn't been programmed to the automobile's system, and this could be very costly. This is why it's a good idea to have two keys that work for a modern automobile and to have the replacement key programmed when necessary.
A keyprogrammer can recode the transponder chip of a new mechanical key or key fob. It is also able to copy the data of an existing key which allows duplicate keys to be made. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with the computer and also provide an interface that works bidirectionally with the immobilizer system.
There are many different types of keyprogrammers on the market. They come in all sizes, shapes and colors. Some are cheap and others are advanced and could cost thousands of dollars.

Transponder Chips
Transponder chips are likely be found in cars manufactured in the last 20 years. This is a little piece of plastic on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When activated by an electro-magnetic field, the chip emits a low level signal. The signal is then absorbed by the special antenna that is attached to the barrel that controls your ignition in your car. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the right one for your particular car.
This is what stops from modifying or hot-wiring the vehicle's ignition system to turn it on. The chip in the key also confirms that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys look like regular keys made of metal but they have a plastic cap. The chip is contained inside the plastic portion of the key and there are a few different types of cuts on these keys: a regular
cut and program car key, a laser
cut and program car keys (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will be received by the chip, causing it to send a signal back to the car. If the car's computer recognizes this signal as the right one, it will turn off the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding a siren. This system is designed to deter individuals from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and committed thief could still be able to get around this system using a special device to detect the signal.
It is evident that the transponder is a good option. Every car owner should take this into consideration in order to safeguard their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate a car in a parking space keys of today can also turn on a heated steering wheel or roll down all windows with just a single press. A lot of these additional features may seem convenient, but they can also make it more difficult to keep track of your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted by a small antenna located in the center of the key. The communication is encrypted, which helps keep others from stealing and retransmitting the signal.
Keyfobs can be programmed in various ways based on the model and make of your vehicle. You may be able to do it yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob, the microchip sends signals to the receiver inside the vehicle that it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob, and then locks or opens the car's doors. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to operate.
When a car is connected with a particular fob, it will only receive signals from that device. Other fobs won't work with the car, even though they appear similar. This protects the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only deal with cars with original fobs, or genuine replacements supplied 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 ones for older models with less sophisticated systems can be programmed with out the need for a dealership.
