How to Program Keys For Cars

Self-programming
As car technology has evolved throughout the years, ignition keys have evolved as well. Gone are the days of simple mechanical-only keys that could be made at an hardware store for less than $10. Modern models come with computers that offer improved 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.
There are several kinds of car key programming that can be done by professional locksmiths. Certain types are more complex and require sophisticated tools. These tools aren't generally accessible to the general public and are utilized only by professionals. This kind of programming for car keys is known as EEPROM Programming and requires soldering, electronic skills and a significant amount of time.
Other forms of programming car keys are much simpler and can be done by the average person. They are typically done using the diagnostics port on the car, that can be accessed using a special key-fob-programming tool. This procedure can be carried out by a trained locksmith with the help of an online guide or the car's owner's manual.
Most professional locksmiths can program a brand new or replacement car key fob swiftly and precisely.

You can be certain that the new key will work and is programmed for your vehicle. In the event that it doesn't, you'll need to pay the dealer for replacement keys and programming services.
Key Programmers
Modern automobiles typically require a key programming procedure to initialize the vehicle's system and allow the car to begin. In certain instances the key will have to be programmed by an auto locksmith or dealer. This is because the key could not work properly or start the vehicle at all. The reason is because the new key hasn't been programmed into the vehicle's system - and this can be very costly. This is why it's a good idea to always have two keys that work for a modern car, so you can get the replacement key programmed when required.
Keyprogrammers can recode the transponder chip of an entirely new mechanical key or key fob. It can also clone the information from 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 have diagnostic software that enables them to communicate with computers and also provide an interface that works bidirectionally with the immobilizer system.
There are many different kinds of keyprogrammers on the market and they come in all shapes and sizes. Certain keyprogrammers are affordable and others can cost thousands of dollar. Certain are designed for specific vehicles and can provide advanced diagnostics of the vehicle's electronic system.
Consult your owner's guide to learn how to program a key for your vehicle. Some manufacturers use proprietary software that only allows dealers to create new keys. Other manufacturers make it simple for anyone to complete.
If you are not able to program the new key by yourself or by yourself, you can have your dealer do it, but it'll be very costly. Another option is to buy an online keyprogrammer. These are cheaper than going to the dealership however they're expensive. Before buying one, do some research on the seller. Some aren't trustworthy and may damage your vehicle.
Transponder Chips
If your car was manufactured within the last 20 years, chances are it contains a transponder chip within of it. It's a small plastic thing in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. This allows the car's computer system to verify that the transponder chip that is in the key is the right one for the car you have.
This is what stops doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip in the key also proves that you are the genuine owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip itself is housed within the plastic part of the key and there are a few different types of cuts on these keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out the signal. The signal is absorbed by the chip, which sends a signal to the vehicle. If the car's computer detects this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.
If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine and notify you via flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However, it is not an absolute security measure. A determined and skilled thief can still get around this system by using a specific device that detects the signal.
As you can see there are quite a number of benefits to having a transponder key. This is something that all vehicle owners should consider if they want to protect their investment and minimize the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to aid in finding cars, or switch on the heated steering wheel. A lot of these additional features may appear convenient but they could make it more difficult to keep the track of your car keys.
Key fobs use radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located within the middle of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.
There are a few different ways to program a key fob, based on your vehicle's model and make. Certain cars let you do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order for them program a replacement key fob or additional one.
When you press a key fob's button the microchip inside sends an informational code to the car's radio that it is linked to. The receiver then compares this information with the 'allowed' signals stored in the fob and then either opens or closes the door. If the information isn't in line an chirping sound is heard and the car isn't able 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 appear like. This protects the integrity of the computer system of the car and prevents the use of unauthorized key fobs to gain control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer's service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
