Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Depending on your vehicle's model and manufacturer the procedure could be as simple as using an extra key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.

Transponder Chips
Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are tiny computer microchips that emit radio signals at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal and the engine is shut down. This technology has been an enormous success in preventing theft of cars.

These kinds of thefts have drastically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits the signal which is detected by a hidden antenna circling the barrel of the ignition. The antenna is programmed to match the frequency of the chip inside the key. The onboard computer of the car will recognize the key as being valid and will allow fuel flow, power the starter or start the engine.

A professional locksmith is better equipped to connect your computer to the car via the OBD port under the steering wheel.
The majority of key fobs today have security features that make it difficult for attackers to clone or replicate the signals they transmit. They include pseudo-random generators that generate a new unlock code every time you press the button on the key fob. This stops attackers from recording and playing back the unlock signal to gain access to your car.
In certain instances, you can buy a replacement keyfob from an authorized dealer or another retailer. Your locksmith at your auto will then program it to work with your car.

The cost of a key fob will differ based on the vehicle model and the type of key however, they generally cost between $85 and $400. This includes labor costs to program the keyfob, as well as any replacement parts.
To make the process more difficult, these car key fobs utilize a specific software system to connect to the car's onboard computer. The software blocks access by unauthorised persons by only allowing keys that have been programmed for a specific car to work. If you change your keys, you will have to program the new key fob into the car in order for it to function.
This is accomplished by using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool lets the locksmith connect to the OBD port (OBD) within the vehicle and then enter the programming mode. The key programming device can be a handheld device that's inexpensive or one that is extravagant and can do more than just program keys (like reading the eeprom file in the ECU).

You can also program new keys with the EEPROM. It is more complex and requires an in-depth understanding of how electronic systems operate. This is why it should be left to a professional who has extensive expertise working on these types of systems.
