Automotive Locksmith Key Programming: The Good, The Bad, And The Ugly
Automotive Locksmith Key Programming
Modern vehicles require some form of key programming. Based on the car's make and model, the process could be as simple as onboard programming using an extra working key or as complex as EEPROM or OBD2 programming.

Transponder Chips
Most modern cars are equipped with transponder chips to prevent car theft. These are tiny computer microchips which emit radio waves of 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 does not recognize the signal it will shut down. This technology has proven to be an enormous success in preventing auto theft.

The fundamental idea behind the transponder system is to make it impossible for thieves to open the doors of your car without the proper key. In the past, thieves would force the ignition switch of your car into the "on" position using a flat screwdriver or even hot-wire the car to bypass the system altogether. These kinds of thefts have drastically reduced thanks to the introduction of the transponder chip.
When you insert a transponder keys into the ignition, it transmits a signal that is received by a hidden antenna circling the barrel of the ignition. The antenna is programmed to detect the particular frequency of the chip within the key. The onboard computer of the car will recognize the key as being valid and allow fuel flow and power the starter to start the engine.
Some vehicles only recognize a specific type of transponder chip depending on the manufacturer. This is why it's essential to ensure that your automotive locksmith is equipped to program your vehicle's keys and fobs properly.

For example an "smart key" which allows you to summon your car into tight parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.

The majority of key fobs are equipped with security features that make it difficult for attackers to duplicate and copy the signals that they transmit. Certain key fobs come with pseudo-random code generators that generate a unique unlock code every time you press the button.

Instead, they suggest buying fobs designed specifically for your vehicle, so that you can be sure they'll function correctly and are less prone to issues like interference or incompatibility. This will save you money over time by avoiding costly repairs or replacements of your fobs.

EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a thorough understanding of how electronic systems work. It is best to delegate it to a professional with expertise with these systems.
Locksmiths can program a key quickly with onboard programming. If everything is done correctly it could take as little as one minute. If the key is not in good working order or the procedure isn't being followed exactly, the process can be as long as half an hour.
There are many different key programmer scanners that can be used with different makes and models of vehicles. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they cover a wide range of vehicle models.
