Automotive Locksmith Key Programming
Modern cars need some form of key programming. Depending on your vehicle’s model and make the process could be as simple as using an extra key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.

Transponder Chips
Transponder chips are used in many newer cars to guard against theft of vehicles. These are tiny computer microchips that emit low-level radio waves. The microchips have a unique serial number which authenticates your key when you connect it to the ignition barrel. If your vehicle isn’t able to recognize the signal, the engine will be shut down. This technology has been an incredible success in preventing auto theft. It has also saved many car key programer owners a lot of money as they don’t need to replace their vehicles.

In the past car thieves would use the flat screwdriver to push the ignition switch of your car to go into “on” mode, or hot-wire it in order to get around the system. Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder keys into the ignition, it will send the signal which is received by a hidden antenna around the barrel of the ignition. The antenna is programmed with the frequency of the chip in the key. The onboard computer in the car will recognize the key as being valid and will allow fuel flow and power the starter to start the engine.
Certain vehicles only recognize a certain type of transponder chip depending on the manufacturer. This is why it’s crucial to make sure that your locksmith in the automotive industry is equipped to program your car’s key and fobs correctly.

It is also possible to press buttons to activate features such as door locks, trunk releases or control of the fuel flap. Certain fobs come with additional functions that can be controlled using the button presses like a “smart” key fob that lets you bring your car into parking spaces that are difficult to access similar to the Genesis GV60 or Tesla.

The cost of a key fob will vary based on the vehicle model and the key type, but they typically run between $85 and $400. This includes labor costs to program the keyfob as well as any replacement parts.
Car key fobs are more intricate because they utilize a software system that works with the onboard computer of the car.

If you decide to replace your keys, you’ll need to program the new key fob to the car in order for it to work.
The most common method to accomplish this is using an auto key programming tool that is compatible with the brand of the vehicle. This tool allows locksmiths to connect to the OBD port of the vehicle and then enter programming mode. Key programming tools can be a handheld device that is inexpensive device or a more expensive one that is capable of performing a wide range of things beyond just key programming (like reading and cloning Eeprom files within the ECU).

EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. It is best to leave it to a professional with expertise with these systems.
Onboard programming is the quickest way for a locksmith to program the new key. If everything is done correctly it can take just one minute. If the key isn’t in good working order or the procedure isn’t being followed exactly, the process can take as long as a half hour.
There are a variety of key programmer scanners available that can be used with different vehicle models and brands.
