Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the car's maker and model, the process could be as simple as programming onboard using an extra working key or as complex as OBD2 or EEPROM programming.
The majority of US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Transponder chips are used in a lot of modern cars to guard against theft of vehicles. These are small computer microchips that emit low-level radio signals. They have an unique serial number that authenticates your keys when you connect it to the ignition barrel. If your car doesn't recognise the signal it will shut down the engine. This technology has been an immense success in stopping auto theft. This technology has also saved car owners a great amount of money by not having to buy new vehicles.
The basic idea behind the transponder system is to make it impossible for thieves to open the doors of your car without a key. In the past, thieves would force your car's ignition switch into the "on" position with the flat screwdriver, or hot-wire the car to bypass the system completely. Transponder chips have drastically reduced these types of thefts.
When you insert the transponder key into the ignition the signal is received 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 then recognize 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. It is therefore essential that your locksmith for cars is equipped with the right equipment to program your keys and remotes for your vehicle.
A reputable locksmith for cars should have an instrument for programming keys for multiple vehicles that can work on many different models and manufacturers of cars. This is a far cheaper alternative than buying specific tools for each model of vehicle. There are also specific automotive key programmer devices that can only be used on specific models of vehicles, but these are less popular. The top automotive locksmiths have the tools to work on any vehicle. Make sure you select an established company that has this type of equipment.
Key FOBs
The name implies that key FOBs are home to the transponder chips that can be programmed to allow your car to recognize and unlock the doors, or start the engine with a push-button ignition. You can also use the buttons to activate features like trunk releases, door locks or controls for the fuel flap. Some fobs have additional functions that can be controlled with the push of a button, such as 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. Tesla or Genesis GV60.
While some replacement key fobs can be programmed by you using the assistance of a user's manual but you'll usually require an automotive locksmith to get a brand new one programmed if yours stops working. A professional is better equipped to connect your computer to the vehicle to the OBD port under the steering wheel.
Most key fobs today include security features that make it difficult for hackers to duplicate or copy the signals they transmit. Some key fobs have pseudo-random code generators that generate a new unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your car.
In most cases you can buy an additional key fob at the dealer or other retailer and have it programmable by your automotive locksmith 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 firms that produce the tools locksmiths employ to programme keys for their customers.
Certain aftermarket key fobs can be marketed as being compatible with all vehicles. However, locksmiths for automotive strongly discourage using them as they're more likely to perform poorly or not work even work at all. Instead, they recommend purchasing fobs designed specifically for your vehicle so that you can be certain they'll work properly and are less susceptible to issues like interfering or not working. This will save money over time by avoiding costly repairs or replacements for your fobs.

This includes the cost of labor to program the key fob, as well as the cost of any needed replacement parts.
These car key fobs are more intricate because they use a software system that works with the onboard computer of the car. The software prevents unauthorized access by only permitting the key to function only if it's programmed for the specific car. This means that if you get your keys replaced, you'll need have the new key fob programmed to the car to function.

The EEPROM programming method is a different one that can be used to program new car keys. It is more complex and requires an in-depth understanding of how electronic systems operate. This is why it's best left to a professional who has extensive experience working with these kinds of systems.
