Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Depending on the vehicle's make and model, the procedure can be as simple as programming onboard using an extra working key or as complex as EEPROM or OBD2 programming.
Most US and Asian automakers share their programming protocol with auto tool manufacturers, so they can create hardware or software for automotive locksmiths.
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 signals. The microchips are equipped with an unique serial number that authenticates your key when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal, the engine will be shut down. This technology has been an immense success in stopping auto theft. This technology has also helped car owners save a good amount of money by not having to replace their vehicles.
The basic idea behind the transponder system is to make it impossible for thieves to get into your car without the proper key. In the past, thieves used an ordinary screwdriver to force the ignition switch of your car to go into "on" mode, or hot-wire it to evade the system. Transponder chips have drastically reduced these types of thefts.
When you insert a transponder key into the ignition, it will transmit the signal which is picked up by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed so that it can read the specific frequency of the chip within the key. The car's computer onboard will recognize that the key is valid and allow fuel to flow, power the starter or start it.
Depending on the manufacturer, certain vehicles can only accept a specific type of transponder chip. It is therefore important that your automotive locksmith is equipped with the correct equipment to program your car's keys and remotes.
A reputable locksmith for cars should have a multi-vehicle key programming tool that can work on many different car manufacturers and models. This is a more cost-effective option than purchasing individual tools for every brand of vehicle. They are not as common, but there are specialised automotive key programmers that can only be used on a specific type of vehicle. The best automotive locksmiths have the tools to work on any vehicle. Be sure to choose an established company that has this kind of equipment.
Key FOBs
Key FOBs are programmable transponder chips that allow your vehicle to open doors and begin the engine with the push of a button ignition. They also have buttons that you can push to activate features like trunk release, door locks or fuel flap control. Some fobs can be controlled by pressing buttons. For example, a "smart key" which allows you to summon your car into tight parking spaces, like a Tesla or Genesis GV60.
You can program replacement key fobs yourself with the assistance of a user guide, but you will need to call an automotive locksmith in the event that yours isn't working. This is because a professional locksmith has the equipment that is specialized and access to the programming tools required to connect your car's computer via the OBD (OBD) port located beneath the steering wheel.
The majority of key fobs today come with security features that make it difficult for criminals to duplicate or copy the signals they transmit. They include pseudo-random generators that generate an entirely new unlock code each time you press the key fob's button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In certain instances, you can buy a replacement keyfob from an auto dealer or other retailer. Your automotive locksmith will then program it to work with your vehicle. This is because the majority of the major US and Asian car manufacturers use key fob programming protocols with third-party firms that create the tools locksmiths utilize to program their customers' keys.
Some aftermarket key fobs may be marketed as compatible with any vehicle. However, automotive locksmiths recommend against using them because they're likely to function poorly or even not even work at all. Instead, reprogram car key suggest buying fobs designed specifically for your specific vehicle so that you can be sure they'll function properly and be less susceptible to issues such as interfering or incompatibility. This will save you money in the long run by avoiding costly repairs or replacing your fobs.

These key fobs have built-in security features that stop hot-wiring (like in a film) and the car won't start if it doesn't have the proper key.
These key fobs are more complex than your traditional mechanical keys, which is why you'll typically find them in the hands of an expert, professional auto locksmith. The cost of a key fob will differ based on the vehicle model and the key type however they usually cost between $85 to $400. This includes the labor cost to program the keyfob and any replacement parts.
Car key fobs are more intricate because they utilize a software system that works with the computer onboard of the car. The software blocks access by unauthorised persons by only allowing keys programmed specifically for a particular car to function. This means that if you get your keys replaced, you'll need to have the new key fob programed to the car for it to function.
The most common method to accomplish this is using the car key programming tool that is compatible with the model of the vehicle. This tool lets the locksmith connect to the OBD port (OBD) within the vehicle and then enter a programming mode. The key programming device can be a handheld device that's inexpensive or one that is fancy and can do more than just programming keys (like reading the eeprom file inside the ECU).
Although some people might attempt to program their own keys using these tools, it's an activity best left to a professional auto locksmith.

You can also program new keys by using the EEPROM. It is more complex and requires a deep understanding of electronic systems. This is why it should be left to a professional that has a lot of experience working with these kinds of systems.
