Modern models come with computers that have improved anti-theft protection. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith, mechanic or dealer for proper operation.
Professional locksmiths can perform various kinds of programming for keys for cars. Certain are complicated and require advanced tools. These tools are not accessible to the general public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a lot of time.
Other kinds of key programming can be done by anyone. They are accomplished using the onboard diagnostic port, which is accessible by a specific tool for key fob programming. This procedure can be carried out by a trained locksmith with the help of an online guide or the car's owner's manual.

Key Programmers
Modern automobiles typically require a key programming process to initialize the vehicle's system and allow the vehicle to start. In some cases the key needs to be programmed by an auto locksmith or dealer. This is because the key may not work properly or start the vehicle in any way. This is because the new key hasn't been programmed to the automobile's system - and this can be quite expensive. It is best to have two keys that work for the modern automobile so that you can program the replacement key whenever required.
A keyprogrammer is a device that can recode the transponder chip on the form of a new key fob or mechanical key. It can also clone the information from an existing key, allowing duplicates to be made. 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 a computer. They also feature a bidirectional user interface for working with an immobilizer system.
There are a variety of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes and colors. Some are affordable, while others are very advanced and could cost thousands of dollars. Some are designed for specific kinds of vehicles and offer advanced diagnostics for the car's electronic systems.
If you're interested in programming an entirely new key for your vehicle, check the owner's manual to learn how to do it. Some manufacturers use proprietary software that only allows dealers to make new keys. Other manufacturers make it easy for anyone to complete.
If you are unable to program the new key yourself and you are unable to do it, then request your dealer to do it, but it'll cost a lot. Another option is to purchase a keyprogrammer online. They're less expensive than going to the dealership however they're not cheap. Make sure you investigate the seller prior to purchasing one. Some aren't reliable and could damage your vehicle.
Transponder Chips
Transponder chips are likely to be found in vehicles manufactured within the past 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 car.
When activated by an electro-magnetic field, the chip emits a low-level signal. This signal is then taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system in the vehicle can then verify that the key's transponder chip is the right one for your car.
This is what prevents from modifying or hot-wiring the vehicle's ignition system to start it. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. car key programming is housed within the plastic part of the key and there are a few different cuts that can be found on the keys: a cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil sends out a signal. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the computer onboard the car recognizes the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and notify you via flashing lights and an alarm. This system is designed to deter people from tampering with the vehicle. However it's not an absolute security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that intercepts the signal.
It is evident that a transponder is a great option. This is something that all vehicle owners should consider if they want to protect their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding a car in a parking lot, today's key fobs can also turn on the heated steering wheel or roll down all windows with a single button push. A lot of these features may seem convenient but they could make it more difficult to keep the track of your car keys.
Key fobs utilize radio frequencies to communicate with each other and with the car. These frequencies are sent by a small antenna in the middle of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your vehicle. Certain models allow you to do it 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 alternative one.
When you press the button on a key fob the microchip sends a signal to the receiver in the vehicle with which it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob, and then opens or locks the car's door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to function.
Once the car is paired with a particular fob, it will only receive signals from the device that is associated with it. In turn, other fobs won't work with the vehicle even though they appear similar. This helps to protect 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 that have original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security expertise that can only be found in the dealer service department. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by customers without the need for dealers.
