25 Shocking Facts About Automotive Locksmith Key Programming

Automotive Locksmith Key Programming

Most modern-day cars require some kind of key programming. Depending on your vehicle's model and make the procedure could be as simple as using an additional key to program the onboard computer, or as complicated as EEPROM or OBD2 programming.

The majority of US and Asian car makers have programming protocols that they share with auto tool makers in order to create hardware and software for locksmiths in the automotive industry to use.

Transponder Chips

Most newer cars use what are called transponder chips to stop car theft. These are microchips in the form of computers that emit low-level radio signals. The microchips have an unique serial number that authenticates your keys when you connect it to 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. It has also saved many car owners a lot of money as they don't need to replace their cars.

The principle behind the transponder system is to make it difficult for thieves to open the doors of your vehicle without a valid key. In the past, thieves would simply push your car's ignition switch into the "on" position with a flat screwdriver or even make use of hot-wires to bypass the system completely. Transponder chips have dramatically decreased the likelihood of theft.

When you place the transponder key in the ignition, the signal is received by an antenna hidden around the barrel. The antenna is programmed to detect the particular frequency of the chip inside the key. The car's onboard computer will then detect that the key is genuine and allow fuel to flow, power the starter or start it.

Depending on the manufacturer certain vehicles can only accept a specific type of transponder chip. Therefore, it is essential that your locksmith for cars is equipped with the right equipment to program your car's keys and remotes.

For instance, a "smart key" that lets you call your car to parking spaces, such as a Tesla or Genesis GV60.

While some replacement key fobs can be programmed by you with the aid of a user's guide but you'll usually require an auto locksmith to get a new one programmed in case yours stops functioning.

They suggest buying fobs designed specifically for your vehicle so that they will work properly and are less prone to issues like interference or incompatibility. This will save you money over the long term by avoiding costly repairs or replacing the fobs.
