Automotive Locksmith Key Programming
Modern cars need some kind of key programming. Depending on your vehicle's model and manufacturer, the process may be as simple as using an extra key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
Most US and Asian automakers use the same programming protocols as auto tool makers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are used in a variety of newer vehicles to stop theft of cars. These are small computer microchips that emit radio signals at a low level. The microchips are equipped with a unique serial number that authenticates your key when you plug it into the ignition barrel. If your vehicle does not recognize the signal and the engine is shut down. This technology has been extremely successful in preventing theft of cars. It also saves many car owners a significant amount of money because they don't have to replace their cars.
The basic concept behind the transponder system is to make it impossible for thieves to get into your vehicle without the correct key. In the past, car thieves would use an ordinary screwdriver to force the ignition switch of your vehicle into the "on" mode or even hot-wire it in order to get around the system. These types of thefts have been drastically reduced with the introduction of the transponder chip.
When you place the transponder key in the ignition the signal is picked up by an antenna that is concealed around the barrel. This antenna is programmed with the frequency of the chip in the key. The car's onboard computer will detect that the key is genuine and allow fuel to flow, power up the starter, or even start it.
Some vehicles only recognize certain type of transponder chip, depending on the manufacturer. This is why it's essential to ensure that your locksmith for automotive is equipped to program your vehicle's keys and fobs properly.
A good automotive locksmith will have a multi-vehicle programming tool that can be used with different automobile models and manufacturers. This is a far cheaper alternative than buying separate tools for each type of vehicle. These aren't as popular but there are automotive key programming tools that can only work on a specific type of vehicle. The top automotive locksmiths are equipped to work on any vehicle. Make sure you select a reputable firm that has this kind of equipment.
Key FOBs

You can also press buttons to trigger features such as trunk releases, door locks or control of the fuel flap. Some fobs can be controlled with the press of buttons. For example the "smart key" that lets you call your car to tight parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
While certain replacement key fobs can be programmed with the help of a user manual, you'll often require an automotive locksmith to get a brand new one programmed in case yours stops working.

The majority of key fobs today come with security features that make it difficult for hackers to duplicate or copy the signals they transmit. Certain key fobs feature pseudo-random code generators, which generate a new unlock code every time you press the button. This prevents attackers capturing and playing back the unlock signal in order to gain access to your vehicle.
In most instances you can buy a replacement key fob from the dealer or from another retailer and have it programmable by a locksmith for your vehicle to work with your particular vehicle.

This will save money over time by avoiding costly repairs or replacements for your fobs.
Tools for programming vehicles used by manufacturers

One of the key components of this technology is a transponder chipset that requires to be programmed to the vehicle by an expert locksmith or dealer/mechanic in order to work. Key fobs are fitted with security features to prevent hot-wiring like in a movie. The car won't start without the correct keys.

The cost of a car key fob varies depending on the model and type of key, but it is usually between $85 and $400. This includes the cost of labor to program the keyfob as well as any replacement parts.
These car key fobs are more complex due to the fact that they use an operating system that communicates with the onboard computer of the car. The software blocks access to unauthorized users by allowing the key to operate if it has been programmed to that specific car. If you change your keys, you will need to program the new key fob into the car to allow it to work.
This is accomplished by using a programing tool for keys for cars that are compatible with the vehicle's brand. This tool lets the locksmith connect to the onboard diagnostics port (OBD) within the vehicle and then enter a programming mode. Key programming devices can be a handheld device that's affordable or extravagant and can do more than just programming keys (like reading the eeprom file inside the ECU).

You can also program new keys with EEPROM. It is more complex and requires a deep understanding of electronic systems. It's best to leave it to a professional with experience with these systems.
Locksmiths can program keys quickly by using onboard programming. When everything is done correctly it could take just one minute. However, if the key isn't in the proper situation or the procedure is not strictly followed, it could take up to an hour.
There are a variety of key programmer scanners which can work with different models and makes of vehicles. The Smart Pro and the Autel IM608 Pro are both well-liked by locksmiths due to the fact that they can be used with a variety of automobile models.
