Automotive Locksmith Key Programming
Modern cars require some type of key programming. Depending on your vehicle's model and manufacturer 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 automakers share their programming protocol with auto tool makers, which means they can create hardware or software for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with transponder chips in order to prevent theft. These are tiny computer microchips which emit low-level radio waves. The microchips have a unique serial number which authenticates your key when you plug it into the ignition barrel. If your car isn't able to recognize the signal, it will shut down the engine. This technology has proven to be an enormous success in preventing auto theft. This technology has also helped car owners save a good deal of money by not having to purchase new cars.
The principle behind the transponder system is to make it impossible for thieves to open the doors of your vehicle without a valid key. In the past car thieves would use the flat screwdriver to push the ignition switch in your car into "on" mode, or wire it hot to bypass the system. These kinds of thefts have been dramatically reduced with the introduction of the transponder chip.
When you insert a transponder key into the ignition, it will send the signal which is picked up by a hidden antenna 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 detect that the key is legitimate and allow fuel to flow, power the starter or start it.
Depending on the manufacturer certain vehicles can only recognize the specific type of transponder chip. This is why it is important to ensure that your locksmith for automotive has the right equipment to program your car's key and fobs properly.
A reputable locksmith for automotive needs to have a multi-vehicle key programming device that works with different car manufacturers and models. This is a less expensive alternative to purchasing specific tools for each type of vehicle. They are not as common however, there are specialist automotive key programming tools that can only be used on a specific type of vehicle. The best locksmiths for automotive have the tools to work on any vehicle. Make sure you choose an established company that has this kind of equipment.
Key FOBs
Key FOBs are programmable transponder chip devices that permit your vehicle to open doors and begin the engine with the push of a button ignition. There are also buttons that you can press to trigger features such as door locks, trunk release or fuel flap control. Some fobs can be controlled with the press of buttons. For instance the "smart key" which allows you to summon your car to tight parking spaces, like the Genesis GV60, Tesla or Genesis GV60.
While certain replacement key fobs can be programmed by you with the help of a user manual but you'll usually require an auto locksmith to have a new one programmed if the one you have isn't working. This is because an expert locksmith has the right equipment and access to the programming tools needed to connect your car's computer via the on-board diagnostics (OBD) port that is located under the steering wheel.
The majority of key fobs come with security features that make it more difficult for criminals to duplicate and copy the signals they transmit. They include pseudo-random sequence generators that generate a fresh unlock code each time you press the button on the key fob. This prevents attackers capturing and replaying the unlock signal to gain access to your car.
In many cases, you can purchase an additional key fob at the dealer or other retailer and then have it programmed by your automotive locksmith to be compatible with your specific vehicle. This is because the majority of major US and Asian auto manufacturers have key-fob programming protocols with the third-party companies who make the tools used by auto locksmiths to program their customer's keys.
Certain aftermarket key fobs can be marketed as being compatible with all vehicles. However, locksmiths for automotive strongly discourage using them as they are likely to work poorly or not work even work at all. Instead, they recommend purchasing fobs specifically designed for your vehicle, so that you can be sure they'll function properly and be less susceptible to issues such as interfering or incompatibility. This will save you money over time, as you avoid costly repairs or replacements for your fobs.
Vehicle Manufacturers' Programming Tools
Automotive technologies have advanced considerably and today's vehicles need computer technology to function. Transponder chips are an essential component of this technology. It must be programmed by a locksmith mechanic, or dealer to work. These key fobs have built-in security features that will prevent hot-wiring (like in a movie) and the car won't start without the correct key.
Key fobs can be somewhat more complicated than a conventional mechanical key. This is why they are usually handled by experienced, professional auto locksmiths. The cost of a car key fob varies dependent on the model and type of key, but it is generally between $85 and $400. This includes the labor to program the key fob and the costs for any required replacement parts.
To make the process more difficult, these car key fobs make use of a special software to connect to the car's onboard computer. The software blocks access to unauthorized users by allowing the key to function only if it's programmed to the car in question. This means that if you need your keys replaced, you'll need to have the new key fob programmed to the car in order for it to function.
This is accomplished using a programming tool for car keys that is compatible with the brand of your vehicle. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter an programming mode. The key programming device could be a handheld device that is inexpensive or one that is sophisticated and capable of doing more than just program keys (like reading the eeprom file inside the ECU).
Although some people might attempt to program their own keys with these tools, it's something best left to a professional auto locksmith. If you're not familiar with the details of the various software systems, it's possible to accidentally change settings that could potentially damage the vehicle. It's important to remember that a knowledgeable professional can help you avoid these problems.
On-Board programming

Modern cars come with transponders that must be acknowledged and accepted by the computer system in order to start. This adds another layer of security that prevents car thieves from starting and driving away with a stolen vehicle. A locksmith who is certified will have the right tools and software to create a key that is compatible with the security system of your vehicle.

G28 Once your locksmith has the key, he'll connect the programming scanner to the diagnostic port of your vehicle. This will put the vehicle into a special programming mode that will allow the locksmith to add a new key to the system.
The key scanner is programmed to communicate with the computer of the vehicle to transmit an electronic code. The computer will detect the code and add it into the list of approved key. In some cases, the scanner will also be able to remove keys that are stolen or lost from the system.
EEPROM programming is another method that can be used to program new car keys. It is more complicated and requires an in-depth understanding of how electronic systems work. This is why it's best left to a professional that has a lot of experience working on these types of systems.
Onboard programming is the fastest way for a locksmith to program a new key. When everything is done correctly it could take just one minute. If the key isn't in good working order or the procedure isn't being followed exactly, the process can be as long as half an hour.
There are a variety of key programmer scanners available that support different vehicle models and brands. The Smart Pro and the Autel IM608 Pro are both extremely popular amongst locksmiths because they support a broad range of automobile models. The system cannot program every vehicle. These devices are also expensive. It's a good idea buy a programmer that receives regular updates as the manufacturer releases new technologies.
