The ignition keys have changed in tandem with the advancements in car technology. The days of simple mechanical keys you could buy from a hardware shop for less than $10 are gone. The newer models have computer systems that are more secure against theft. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith car dealer or mechanic for proper operation.

Professional locksmiths can perform various types of programming for keys for cars. Some are complex and require specialized tools. These tools are generally not accessible to the general public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot time.

Other kinds of key programming can be done by anyone. These are usually done by using the diagnostics port on the car keys programmer, that can be accessed using the key-fob-programming device. A locksmith can perform this procedure with the help of an online guide and the owner's manual.

This way, you will ensure that the new key has been programmed to your reprogramme car key and will function. You'll have to pay the dealer for programming and replacement keys if you do not.

Key Programmers

Modern vehicles frequently require a key programming process to initialize the vehicle's system and allow the vehicle to start. In many cases keys must be set up by the dealer or auto locksmith. The key may not work properly or not start the vehicle at all. This is because the new key hasn't been programmed to the car's system. This can be quite expensive. It is recommended to have two keys that are compatible with your current car so you can program the replacement key when needed.

A keyprogrammer can recode the transponder chip on an entirely new mechanical key or key fob. It can also clone the data of an existing key in order to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with the computer as well as an interface that works bidirectionally with the immobilizer system.

There are many different kinds of keyprogrammers that are available and they are available in all sizes and shapes. Some are affordable while others are advanced and can cost thousands of dollars.

Some manufacturers use proprietary technology that guarantees that the dealership is the sole entity able to create new keys, however other manufacturers make it simple for anyone to do it themselves.

These are cheaper than visiting a dealership however, they're not cheap. Before you purchase one make sure you research the seller. Some aren't reliable and may damage your vehicle.

Transponder Chips

If your car was manufactured within the past 20 years, then it has a transponder inside of it. It's a tiny plastic piece on the back of your key which contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.

When it is activated by an electro-magnetic field the chip emits a low-frequency signal. This signal then gets taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to verify that the transponder chip that is in the key is the correct one for your specific vehicle.

This is the reason why doing hot-wiring or altering the ignition system of the vehicle to get it started. The chip inside the key also verifies that you are the legal owner of the vehicle. This will help reduce car theft.

Transponder keys look like normal keys but have caps made of plastic. The chip itself is housed inside the plastic portion of the key and there are a few different types of cuts on the keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.

The circuit in the induction coil will emit a signal when the transponder is inserted into an ignition barrel. The signal is received 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 shut down the vehicle immobilizer and allow the engine to start.

If the car does not recognize the transponder signal as the right one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to deter people from trying to hack into the vehicle, however it is not a foolproof security measure. A skilled and skilled criminal can still get around this system by using a specific device that blocks the signal.

As you can see there are quite a number of benefits to having a transponder key. All car owners should consider this in order to safeguard their investment and minimize theft risk.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to help locate cars, or turn on the heated steering wheel. These extra features can make it difficult to locate your car keys.

Key fobs are able to 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 keep others from stealing and replicating the signal.

Keyfobs can be programmed in different ways based on the model and brand of your vehicle. You can sometimes do this yourself, but the majority of newer automobiles 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 a code to the car's radio that it is linked to. The receiver compared this information to the signals that are allowed in the fob and then either opens or locks the door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.

Once the car is associated with a particular fob, it only accepts signals from that device. Other fobs won't work with the car, even though they look like. This safeguards the integrity of the computer system of the car and blocks unauthorized key fobs gaining control of it.

The majority of newer dealers will only work on a car key reprogrammed with original fobs or genuine replacements supplied by the manufacturer. The reason for this is that the only place that has the expertise to prepare the replacement fob is a dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by customers without the need of dealers.
