Automotive Locksmith Key Programming

Modern automobiles require some kind of key programming. Depending on your vehicle's model and make the process could be as simple as using an additional key to program the onboard computer or as complicated as OBD2 programming or EEPROM.

Most US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can create software or hardware for automotive locksmiths.

Transponder Chips

Transponder chips are in many newer cars to guard against theft of vehicles. These are microchips in the form of computers that emit radio signals at a low level. The microchips have a unique serial number that authenticates your key when you plug it into the ignition barrel. If your vehicle does not recognize the signal it will shut down. This technology has proven to be a huge success in preventing theft of cars. It also saves many car owners a lot of money because they don't have to replace their vehicles.


The basic concept behind the transponder system is to make it hard for thieves to start your vehicle without the correct key. In the past, thieves would simply push your car's ignition switch into the "on" position with the flat screwdriver, or use hot wires to disable the system altogether. Transponder chips have dramatically reduced the number of thefts.

When you insert a transponder key into the ignition, it will transmit an electrical signal that is detected by a hidden antenna around the barrel of the ignition. programmed car keys is programmed to match the frequency of the chip in the key. The onboard computer in the car will then recognise the key as valid and will allow fuel flow and start the starter. start the engine.

They suggest purchasing fobs that are designed specifically for your vehicle to ensure they work correctly and are less prone to issues such as interference or incompatibility.

You can also program new keys with EEPROM. It is more complicated and requires a thorough understanding of how electronic systems work. It is best to delegate it to a professional who has expertise with these systems.

Locksmiths can program keys quickly using onboard programming. If everything is done properly it could take just one minute. However, if the key isn't placed in the right situation or the procedure is not strictly followed, it could take up to an hour.

There are numerous key programmer scanners which can work with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both very popular amongst locksmiths because they can be used with a variety of vehicles. However, no system can program every vehicle on the market.
