Automotive Locksmith Key Programming
Most modern-day cars require some kind of key programming. Depending on the car's maker and model, the procedure can be as simple as programming onboard using a spare working key or as complicated as EEPROM or OBD2 programming.
The majority of US and Asian automakers share their programming protocol with auto tool makers, so they can develop hardware or software for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips to stop car theft. These are tiny computer microchips that emit low-level radio signals. The microchips are equipped with an unique serial number that authenticates your key whenever you insert it into the ignition barrel. If your vehicle isn't able to recognize the signal and the engine is shut down. This technology has proved to be an immense success in stopping auto theft. It has also saved many car owners a significant amount of money because they don't have to replace their vehicles.
The principle of the transponder system is to make it hard for thieves to get into your car without the right key. In the past, thieves would use a flat screwdriver to force the ignition switch in your car to go into "on" mode or even hot-wire it to evade the system. Transponder chips have drastically reduced the number of thefts.
When you insert a transponder key into the ignition, it transmits an electrical signal that is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed to match the frequency of the chip within the key. The car's onboard computer will recognise that the key is legitimate and allow fuel to flow, power the starter or begin it.
Based on the manufacturer, certain vehicles can only accept the specific type of transponder chip. This is why it's important to ensure that your automotive locksmith has the right equipment to program your vehicle's keys and fobs properly.

The majority of key fobs today have security features that make it difficult for hackers to clone or replicate the signals they transmit. Some key fobs have pseudo-random code generators which generate a unique unlock code each time you press the button. This is to prevent attackers from capturing and playing back the unlock signal in order to gain access to your car.

They suggest purchasing fobs that are designed specifically for your vehicle to ensure they work correctly and are less susceptible to issues like interference or incompatibility. This will save you money over time by avoiding costly repairs or replacements of your fobs.
