Automotive Locksmith Key Programming
Modern automobiles require some kind of key programming. Based on the model and make the procedure could be as simple as using a spare key to programme the computer onboard, or as complicated as OBD2 programming or EEPROM.
Most US and Asian automakers share their programming protocol with auto tool makers, so they can design hardware or software for automotive locksmiths.
Transponder Chips
Transponder chips are in many newer cars to guard against theft of vehicles. These are microchips in the form of computers that emit radio signals at a low level. The microchips have a unique serial number which authenticates your key when you plug it into the ignition barrel. If your vehicle isn't able to recognize the signal, the engine will be shut down. This technology has been a huge success in preventing theft of cars. This technology has also helped car owners save a good amount of money since they don't have to purchase new cars.
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 would use a flat screwdriver to force the ignition switch of your car to go into "on" mode, or hot-wire it to bypass the system. Transponder chips have dramatically reduced the number of thefts.
When you insert a transponder key into the ignition, it transmits an electrical signal that is detected by a hidden antenna around the barrel of the ignition. The antenna is programmed to match the frequency of the chip in the key. The car's computer onboard will recognise that the key is valid and allow the fuel to flow, then power up the starter, or even begin it.
Depending on the manufacturer, certain vehicles can only accept the specific type of transponder chip. This is why it's essential to ensure that your locksmith for automotive has the right equipment to program your car's key and fobs properly.
A reliable locksmith for cars will utilize a multi-vehicle programmable device which can be used on many different models and brands of cars.

There are also specific key programming devices for automotive that are only suitable for one particular brand of vehicle however, they are less common. The best locksmiths for automotive have the tools needed to work on any vehicle. Make sure you choose a reputable firm that has this kind of equipment.
Key FOBs
The key FOBs are programmable transponder chip devices that permit your vehicle to unlock doors and start the engine using the push of a button ignition. You can also press buttons to trigger features such as trunk releases, door locks or control of the fuel flap. Some fobs have additional functions that can be controlled with the press of a button, such as a "smart" key fob that allows you to bring your car to parking spots that are tight, like you would with the Genesis GV60, Tesla or Genesis GV60.
You can program some replacement key fobs yourself with the help from an instruction manual, however you'll need to contact an automotive locksmith if the one you have has stopped functioning. A professional is better equipped to connect the computer of your car via the OBD port on the steering wheel.
The majority of key fobs today have security features that make it difficult for attackers to duplicate or copy the signals they transmit. These include pseudo-random sequence generators that generate a fresh unlock code every time you press the button on the key fob. This prevents attackers capturing and playing back the unlock signal to gain access to your car.
In some instances you can purchase a replacement keyfob from a dealership or another retailer. The locksmith you choose to use will then program it to work with your car. This is because most of the major US and Asian car makers use key fob programming protocols with third-party companies who make the tools that auto locksmiths utilize to program their customers' keys.
Certain aftermarket key fobs can be advertised as compatible with any vehicle. However, locksmiths for automotive advise against using them since they are likely to work poorly or even not even work at all. Instead, they suggest purchasing fobs specifically designed for your vehicle, so that you can be sure they'll function properly and be less prone to issues such as interfering or incompatibility. This will save you money in the end by avoiding expensive repairs or replacing the fobs.

One key element of this technology is a transponder chipset that needs to be programmed to the vehicle by a locksmith or dealer/mechanic in order to work. Key fobs with embedded security features that stop hot-wiring (like in a film) and the car won't start without the proper key.
Key fobs are more complicated than a traditional mechanical key and are the reason you'll usually find them in the hands of an expert, professional auto locksmith. The cost of a key fob can vary depending on the car model and the type of key however they usually cost between $85 to $400. This includes the labor to program the key fob and the cost of any needed replacement parts.
To complicate the process, these car key fobs make use of a special software to connect to the car's onboard computer. The software blocks access to unauthorized users by only allowing the key to function if it has been programmed for the specific car. If you change your keys, you will have to program the new key fob to the car in order for it to work.
The most popular method to do this is by using the car key programming tool that is compatible with the brand 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 tool can be a simple handheld device or a high-end one that is capable of performing various things beyond just key programming (like reading and cloning eeprom files in the ECU).

You can also program new keys by using the EEPROM. It is more complicated and requires a deep understanding of how electronic systems operate. This is why it should be left to a professional that has extensive expertise working on these types of systems.
Onboard programming is the quickest way for a locksmith to program an entirely new key. It can take less than an hour if everything is completed correctly. If the key isn't in the right condition or the procedure isn't being followed precisely, the procedure could take as long as a half hour.
There are numerous key programmer scanners which can work with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both very popular with locksmiths since they can be used with a variety of vehicle models. The system cannot program every vehicle.
