Automotive Locksmith Key Programming
Modern cars need some type of key programming. Depending on the model and manufacturer the process could be as simple as using a spare 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 design hardware or software for automotive locksmiths.
Transponder Chips
The majority of newer cars have transponder chips to prevent car theft. These are tiny computer microchips that emit radio waves at a low level. The microchips have a unique serial number which authenticates your key whenever you plug it into the ignition barrel. If your vehicle doesn't recognize the signal, it will shut down the engine. This technology has been an enormous success in preventing car theft. It also saves many car owners a significant amount of money since they don't need to replace their cars.
The principle behind the transponder system is to make it impossible for thieves to open the doors of your car without a key. In the past, car thieves would simply force your car's ignition switch into the "on" position using an ordinary screwdriver or use hot wires to disable the system completely. These kinds of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will transmit an electrical signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. This antenna is programmed with the frequency of the chip in the key. The onboard computer in the car will then recognize the key as being valid and will allow fuel flow, power the starter or start the engine.
Based on the manufacturer, some vehicles will only recognise certain types of transponder chip. Therefore, it is essential that your automotive locksmith is equipped with the right equipment to program your keys and remotes for your vehicle.
A reputable locksmith for automotive will utilize a multi-vehicle programmable device that can be used on a variety of different car models and manufacturers. This is a cheaper solution than buying separate tools for each brand of vehicle. There are also specially-designed key programming devices for automotive that can only be used on one particular brand of vehicle, but these are less popular. The best locksmiths for automotive have the tools to work on any vehicle. Make sure you select a reliable company that is equipped with this kind of equipment.
Key FOBs
As the name implies, key FOBs house the programmable transponder chips that enable your vehicle to recognize and open the doors or start the engine using a push button ignition. They also have buttons you can press to activate features like trunk release, door locks or fuel flap control. Some fobs can be controlled with the press of buttons. For example an "smart key" which allows you to summon your car into tight parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
You can program spare key fobs by yourself with the assistance of a user guide, but you'll need to contact an automotive locksmith if yours has stopped functioning. This is because a professional has the specialized equipment and access to the programming tools needed to connect your car's computer through the OBD (OBD) port beneath the steering wheel.
The majority of key fobs are equipped with security features that make it harder for attackers replicate and clone the signals they transmit. Some key fobs have pseudo-random code generators that generate a unique unlock code every time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many instances, you can purchase a replacement key fob from the dealership or another retailer and have it programmed by your locksmith in your car to be compatible with your particular vehicle. This is due to the fact that most of the major US and Asian car makers have key fob programming protocols with third-party companies that make the tools that auto locksmiths use to programme keys for their customers.
While some aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths don't recommend using them since they will likely only work poorly or not at all. They suggest buying fobs designed specifically for your vehicle so that they work correctly and are less prone to issues like interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing the fobs.
Tool for programming the vehicle manufacturers

It has to be programmed by a locksmith, mechanic or dealer to function. Key fobs come with built-in security features that will prevent hot-wiring (like in a film) and the car will not start if you don't have the proper key.
These key fobs are a bit more complex than your traditional mechanical key and are the reason you'll typically find them in the hands of an expert professional auto locksmith. The cost of the car key fob is dependent on the model and type of key, but it is typically between $85 and $400. This includes the labor to program the key fob, as well as the costs for any required replacement parts.
To make the process more complicated, these car key fobs make use of a special software to work with the car's onboard computer. The software blocks access to unauthorised users by only permitting keys that have been programmed for a specific vehicle to work. If you replace your keys, you will have to program the new key fob into the car in order for it to function.
The most common way to accomplish this is using an auto key programming tool that is compatible with the brand of the vehicle. This tool lets the locksmith connect to the onboard diagnostics port (OBD) in the vehicle and then enter the programming mode. The key programming tool can be a handheld device that is inexpensive device or a fancy one that can do various things beyond key programming (like reading and cloning the EEEPROM files in the ECU).
Some people might attempt to program their keys by themselves using these tools. However it's best to leave this task to a professional auto locksmith.

You can also program new keys with the EEPROM. It is more complicated 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.
Locksmiths can program a key quickly using onboard programming. It can take as little as an hour if everything is done correctly. If the key isn't in the right situation or the procedure is not adhered to, it could take as long as a half hour.
There are a variety of key programmer scanners which can work with various models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro are very popular with locksmiths due their broad range of models for vehicles. There is no system that can program every vehicle. These machines are also quite expensive. It's best to purchase an instrument that receives regular updates from the manufacturer as new technologies are released. Your computer's programming software will soon become obsolete if you don't do this.
