20 Myths About Automotive Locksmith Key Programming: Busted

Automotive Locksmith Key Programming

Modern cars require some type of mobile key programmer programming. Based on the model and make, the process may be as simple as using a spare key to programme the computer onboard, or as complex as EEPROM or OBD2 programming.

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

Transponder Chips

Transponder chips are used in a lot of modern cars to stop theft of cars. These are tiny computer microchips that emit radio signals at a low level. They have a unique serial number which authenticates your keys when you connect it to the ignition barrel. If your car isn't able to recognize the signal it will stop the engine. This technology has been an enormous success in preventing auto theft. It has also saved many car owners a lot of money since they don't need to replace their cars.

In the past, car thieves would force your car's ignition switch into the "on" position with a flat screwdriver or even hot-wire the car to bypass the system altogether. These types of thefts have drastically reduced with the introduction of the transponder chip.

When you insert the transponder keys in the ignition the signal is received by an antenna hidden around the barrel. The antenna is programmed with the frequency of the chip in the key. The onboard computer in the car will then recognise the key as valid and allow fuel flow, power the starter or begin the engine.

Depending on the manufacturer, certain vehicles can only recognize certain types of transponder chip. This is why it is essential to ensure that your automotive locksmith has the right equipment to program your car's key and fobs properly.

A professional locksmith is better equipped to connect the computer of your car via the OBD port under the steering wheel.

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