Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming using an extra working key or as complicated as OBD2 or EEPROM programming.
Most US and Asian auto manufacturers use the same programming protocols as auto tool makers, so they can develop tools or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips that emit low-level radio waves. They have a unique serial number that authenticates your key whenever you plug it into the ignition barrel. If your car doesn't recognise the signal it will stop the engine. This technology has been an enormous success in preventing auto theft. It also saves many car owners a significant amount of money because they don't need to replace their cars.
The principle of the transponder system is to make it difficult for thieves to get into your car without the right key.

Transponder chips have drastically decreased the likelihood of theft.
When you insert a transponder keys into the ignition, it will transmit the signal which is picked up by a hidden antenna circling the barrel of the ignition. The antenna is programmed to read the specific frequency of the chip within the key. The car's onboard computer will detect that the key is genuine and allow the fuel to flow, then power the starter or begin it.
Depending on the manufacturer certain vehicles can only recognize certain types of transponder chip. This is why it's crucial to make sure that your locksmith for automotive has the right equipment to program your vehicle's keys and fobs correctly.
