Automotive Locksmith Key Programming

Modern cars need some type of key programming. Depending on the car's maker and model, the process can be as easy as onboard programming with an extra working key or as complicated as OBD2 or EEPROM programming.

Most US and Asian automakers share their programming protocol with auto tool makers, which means they can develop tools or hardware for locksmiths in the automotive industry.

Transponder Chips

Most modern cars are equipped with what are called transponder chips in order to prevent theft. These are microchips in the form of computers that emit radio signals at a low level. They are equipped with a unique digital serial number that authenticates the key to your car when it is connected to the ignition barrel. If your vehicle doesn't recognize the signal it will stop the engine. This technology has been extremely successful in preventing car theft. It has also saved many car owners a lot of money because they don't need to replace their cars.

The principle behind the transponder system is to make it impossible for thieves to start your vehicle without a valid key. In the past, thieves would simply force your car's ignition switch into the "on" position with a flat screwdriver or even make use of hot-wires to bypass the system altogether. These kinds of thefts have been drastically reduced thanks to the introduction of the transponder chip.

When you insert a transponder key into the ignition, it will send a signal that is picked up by a hidden antenna that is positioned around the barrel of the ignition. 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 legitimate and allow fuel to flow, power up the starter, or even begin it.

Certain vehicles only recognize a certain type of transponder chips, depending on the manufacturer. It is therefore important that your locksmith for cars is equipped with the right equipment to program your keys and remotes for your vehicle.

Today, most key fobs come with security features that make it difficult for criminals to clone or replicate the signals they transmit. Some key fobs have pseudo-random code generators, which generate a new unlock code every time you press the button. This prevents attackers from capturing and replaying the unlock signal to gain access to your vehicle.

In most cases you can purchase an additional key fob at the dealership or another retailer and then have it programmed by a locksmith for your vehicle to work with your particular vehicle. This is due to the fact that most of the major US and Asian car manufacturers use key fob programming protocols with third-party firms that make the tools that locksmiths use to program keys for their customers.

While some of the aftermarket key fobs are marketed as being compatible with any vehicle, most automotive locksmiths do not recommend using them as they will likely only work poorly or not at all.

This will save you money over the long term by avoiding expensive repairs or replacing your fobs.

The software prevents unauthorized access by allowing the key to function only if it's programmed to that specific car. If you change your keys, you will have to program the new key fob in the car key programmed in order for it to work.

This is done by using a tool for programming keys for cars that are compatible with your vehicle's brand. This tool lets the locksmith connect to the OBD port (OBD) in the vehicle and then enter an programming mode.
