"Ask Me Anything": Ten Responses To Your Questions About Automotive Locksmith Key Programming
Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on the model and manufacturer the process could be as simple as using an extra key to program the onboard computer or as complex as EEPROM or OBD2 programming.
Most US and Asian automobile manufacturers use the same programming protocols as auto tool makers in order to create tools and hardware for locksmiths working in automotive vehicles.
Transponder Chips
Most newer cars use what are called transponder chips to prevent car theft. These are tiny computer microchips which emit low-level radio waves. 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 an enormous success in preventing car theft. It also saves many car owners a significant amount of money because they don't have to buy new their vehicles.
The basic concept behind the transponder system is to make it hard for thieves to start your car without the right key. In the past car thieves would use a flat screwdriver to force the ignition switch of your vehicle to go into "on" mode or even hot-wire it in order to bypass the system. Transponder chips have drastically decreased the likelihood of theft.
When you place the transponder key in the ignition, the signal is received by an antenna that is hidden within the barrel. The antenna is programmed with the frequency of the chip within the key. The car's computer onboard will detect that the key is valid and allow fuel to flow, turn up the starter, or even begin it.
Depending on the manufacturer some vehicles will only recognise a specific type of transponder chip. Therefore, it is essential that your locksmith for cars is equipped with the correct equipment to program your keys and remotes for your vehicle.
