Automotive Locksmith Key Programming
Modern cars require some type of key programming. Based on the car's make and model, the process can be as simple as onboard programming with a spare working key or as complex as EEPROM or OBD2 programming.
Most US and Asian automakers use the same programming protocols as auto tool manufacturers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are in a variety of newer vehicles to guard against theft of vehicles. These are tiny computer microchips which emit low-level radio waves. 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 car isn't able to recognize the signal it will shut down the engine. This technology has proven to be an enormous success in preventing auto theft. This technology has also helped car owners save a huge amount of money since they don't have to replace their vehicles.

When you insert the transponder keys in the ignition, the signal is picked up by an antenna that is hidden within the barrel. This antenna is programmed so that it can detect the particular frequency of the chip inside the key. The onboard computer in the car will recognize the key as being valid and will allow fuel flow, power the starter or start the engine.
Depending on the manufacturer, some vehicles will only recognise a specific type of transponder chip. This is why it is essential to ensure that your automotive locksmith has the appropriate equipment to program your car's keys and fobs correctly.
A good automotive locksmith should have an instrument for programming keys for multiple vehicles that works with different car manufacturers and models. This is a far cheaper option than buying separate tools for each type of vehicle. There are also specialised key programming tools for automobiles that are only suitable for one particular brand of vehicle, but these are less common. The top automotive locksmiths have the tools needed to work on any vehicle. Be sure to choose an established company that has this type of equipment.

The majority of key fobs come with security features to make it more difficult for criminals to replicate and clone the signals that they transmit. They include pseudo-random generators that generate an entirely new unlock code every time you press the button on the key fob. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.

The cost of a key fob can differ based on the vehicle model and the type of key however, they generally cost between $85 to $400. This includes the cost of labor to program the keyfob and any replacement parts.

If you replace your keys, you will have to program the new key fob to the car for it to function.
This is accomplished using a programming tool for keys for cars that are compatible with the vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter the programming mode. Key programming devices can be a handheld device that's affordable or sophisticated and capable of doing more than just programming keys (like reading the eeprom files in the ECU).
Some people might try to program their keys themselves using these tools. However, this is best left to a professional auto locksmith.

In certain instances the scanner may also be able to delete keys that are stolen or lost from the system.
The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires a deep understanding of how electronic systems function. It is best to leave it to a professional who has expertise with these systems.
Onboard programming is the most efficient method for locksmiths to program a new key. It takes as little as an hour if everything is completed correctly. If the key isn't placed in the correct condition or the procedure isn't strictly followed, it could take up to a half hour.
There are many key programmer scanners on the market that can be used with different car models and makes.
