Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming using a spare key that works or as complex as EEPROM or OBD2 programming.
Most US and Asian automakers share their programming protocol with auto tool makers, which means they can design software or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are in a lot of modern cars to prevent car 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 plugged into the ignition barrel. If your vehicle doesn't recognize the signal it will shut down the engine. This technology has proven to be an enormous success in preventing auto theft. It has also saved many car owners a significant amount of money as they don't have to replace their vehicles.
The principle behind the transponder system is to make it difficult for thieves to get into your car without the proper key. In the past, thieves would force the ignition switch of your car into the "on" position with an ordinary screwdriver or use hot wires to disable the system entirely. These kinds of thefts have been drastically decreased with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it transmits an electrical signal that is picked up by a hidden antenna around the barrel of the ignition. see this is programmed to read the specific frequency of the chip inside the key. The onboard computer of the car will recognize the key as valid and will allow fuel flow, power the starter or begin the engine.
Certain vehicles only recognize a certain type of transponder chips depending on the manufacturer. Therefore, it is essential that your automotive locksmith is equipped with the appropriate equipment to program your keys and remotes for your vehicle.
A good automotive locksmith should have a multi-vehicle key programming device that can work on many different car manufacturers and models.

The best locksmiths for automotive have the tools to work on any vehicle. Be sure to choose a reliable company that is equipped with this type of equipment.

For instance the "smart key" that lets you call your car into tight parking spaces, such as the Genesis GV60 or a Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you using the aid of a user's guide but you'll usually require an auto locksmith to get a new one programmed if the one you have isn't functioning. A professional locksmith is more equipped to connect the computer of your vehicle to the OBD port located under the steering wheel.

Today, most key fobs come with security features that make it difficult for criminals to clone or replicate the signals they transmit. Certain key fobs feature pseudo-random code generators that generate a new unlock code every time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.
In most instances you can purchase an alternative key fob from the dealer or other retailer and have it programmed by a locksmith for your vehicle to fit your specific vehicle. This is due to the fact that most of the major US and Asian car manufacturers share their key fob programming protocols with third-party companies who make the tools that locksmiths employ to programme keys for their customers.
Certain key fobs from the aftermarket may be marketed as compatible with any vehicle. However, locksmiths for automotive advise against using them since they're likely to function poorly or not work even work at all. They suggest buying fobs designed specifically for your vehicle so that they function properly and are less prone to issues such as interference or incompatibility. This will save you money over the long term by avoiding expensive repairs or replacing your fobs.

This includes the cost of labor to program the key fob and the costs for any required replacement parts.

If you change your keys, you'll have to program the new key fob to the car in order 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 lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter the programming mode. The key programming tool can be a simple handheld device or a high-end one that is capable of performing many things beyond key programming (like reading and cloning the eeprom files in the ECU).

In certain instances the scanner may also be able to erase keys that have been stolen or lost from the system.
