Automotive Locksmith Key Programming
Most modern-day cars require some form of key programming. Based on the model and make the procedure could be as simple as using a spare key to program the onboard computer, or as complex as EEPROM or OBD2 programming.
The majority of US and Asian automobile manufacturers have programming protocols that they share with auto tool makers so that they can develop tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most newer cars use transponder chips in order to prevent theft. These are small computer microchips that emit radio signals at a low level. They have a unique digital serial number that authenticates the key to your car when it is plugged into the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has proven to be an enormous success in preventing theft of cars. This technology has also saved car owners a great amount of money since they don't have to buy new vehicles.
The transponder system's basic idea is to make it impossible for thieves to start your vehicle without a valid key. In the past, car thieves used the flat screwdriver to push the ignition switch in your car into the "on" mode or even hot-wire it in order to bypass the system. Transponder chips have dramatically decreased the likelihood of theft.
When you insert a transponder key into the ignition, it will transmit an electrical signal that is detected by a hidden antenna circling the barrel of the ignition. This antenna is programmed to detect the specific frequency of the chip inside the key. The computer onboard of the car will recognize the key as valid and will allow fuel flow and power the starter to start the engine.
Certain vehicles only recognize a specific type of transponder chip according to the manufacturer. It is therefore essential that your locksmith for cars is equipped with the appropriate equipment to program your car's keys and remotes.

A professional locksmith is better equipped to connect your computer to the vehicle via the OBD port located under the steering wheel.
The majority of key fobs today come with security features that make it difficult for attackers to clone or replicate the signals they transmit. They include pseudo-random sequence generators that generate a 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 most cases, you can purchase a replacement key fob from the dealership or another retailer and then have it programmed by your automotive locksmith to work with your specific vehicle. This is because the majority of major US and Asian automakers have key-fob programming protocols with the third-party firms who make the tools used by auto locksmiths to program their customer's keys.

The software prevents unauthorized access by only permitting the key to function if it has been programmed for the specific car. If you decide to replace your keys, you will have to program the new key fob into the car for it to function.

This tool lets the locksmith connect to the onboard diagnostics port (OBD) within the vehicle and then enter the programming mode. Key programming tools can be a handheld device that is inexpensive device or a more expensive one that can perform many things beyond just key programming (like reading and cloning eeprom files in the ECU).

EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a thorough understanding of electronic systems. It is best to delegate it to a professional who has knowledge of these systems.
Onboard programming is the most efficient method for locksmiths to program an entirely new key. It takes as little as one minute if everything is done correctly. If the key is not in good working order or the procedure isn't being followed precisely, the procedure could take up to half an hour.
There are a variety of key programmer scanners that can be used 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 vehicle models. The system cannot program every vehicle. In addition, these machines are expensive. It is best to buy an instrument that receives regular updates from the manufacturer whenever new technologies are developed.
