"Ask Me Anything": Ten Responses To Your Questions About Automotive Locksmith Key Programming
Automotive Locksmith Key ProgrammingModern cars need some kind of key programming. Depending on your vehicle's model and make the procedure 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 automakers share their programming protocol with auto tool makers, which means they can design software or hardware for automotive locksmiths.
Transponder Chips
Most modern cars are equipped with what are called transponder chips to prevent car theft. These are microchips in the form of computers that emit radio signals at a low level. They have a unique serial number that authenticates your key whenever 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 been a huge success in preventing car theft. It has also saved many car owners a significant amount of money because they don't have to replace their vehicles.
The basic 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 car thieves would use an ordinary screwdriver to force the ignition switch of your vehicle into the "on" mode, or hot-wire it in order to evade the system. Transponder chips have drastically reduced these types of thefts.
When you insert the transponder key into the ignition, the signal is received by an antenna hidden around the barrel. This antenna is programmed with the frequency of the chip inside the key. The car's computer onboard will recognize that the key is genuine and allow fuel to flow, turn up the starter or begin it.
Some vehicles only recognize a certain type of transponder chips depending on the manufacturer. It is therefore essential that your automotive locksmith is equipped with the right equipment to program your keys and remotes for your vehicle.
A good automotive locksmith will possess a multi-vehicle programing device that can be used on many different models and brands of cars. This is a cheaper alternative than buying specific tools for each model of vehicle. These are less common however, there are specialist automotive key programmers that are able to only be used on a specific model of vehicle. The best automotive locksmiths have the tools needed to work on any vehicle. Be sure to choose a reputable firm that has this type of equipment.
Key FOBs
The name implies that key FOBs house the programmable transponder chips that enable your vehicle to identify and unlock the doors or start the engine using push-button ignition. They also have buttons that you can press to activate features such as trunk release, door locks or control of the fuel flap. Some fobs can be controlled using buttons. For instance the "smart key" that allows you summon your car to parking spaces, such as the Genesis GV60, Tesla or Genesis GV60.
You can program some spare key fobs by yourself with the help from a user guide, but you'll need to call an automotive locksmith if yours isn't functioning. A professional is better equipped to connect the computer of your vehicle via the OBD port on the steering wheel.
The majority of key fobs are equipped with security features to make it more difficult for criminals to duplicate and copy the signals that they transmit. These include pseudo-random sequence generators that generate a fresh unlock code each time you press the button on your key fob. This stops attackers from recording and replaying the unlock signal in order to gain access to your car.
In many instances, you can purchase an additional key fob at the dealership or another retailer and then have it programmed by your locksmith in your car to be compatible with your particular vehicle. This is because the majority of major US and Asian automakers use the same key-fob programming protocol with the third-party companies who make the tools used by auto locksmiths to program their customer's keys.
Some aftermarket key fobs may be advertised as compatible with any vehicle. However, locksmiths for automotive advise against using them since they're likely to function poorly or even not at all. Instead, they suggest buying fobs specifically designed for your vehicle so that you can be sure they'll work properly and are less prone to issues like interfering or incompatibility. This will save you money over time by avoiding costly repairs or replacements of your fobs.

Automotive technologies have advanced considerably, and today's vehicles require computer technology to function. A transponder chip is an essential component of this technology. It needs to be programmed by a locksmith mechanic or dealer to function. Key fobs are fitted with security features that prevent hot-wiring, like in a film. The car won't start without the correct keys.
Key fobs are a bit more complex than the traditional mechanical key, which is why you'll usually find them in the hands of an expert professional auto locksmith. The cost of a key fob may vary depending on the car model and the type of key, but they typically run between $85 and $400. This includes labor costs to program the keyfob, as well as any replacement parts.
To make the process more complicated the car key fobs use a special software system to connect to the car's onboard computer. The software prevents unauthorized access by allowing the key to function only if it's been programmed to that specific car. If you change your keys, you'll need to program the new key fob to the car for it to work.
The most common method to accomplish this is using a car key programming tool that is compatible with the model of the vehicle. This tool lets the locksmith connect to the onboard diagnostics port (OBD) within the vehicle and then enter an programming mode. Key programming devices can be a handheld device that is affordable or fancy and can do more than just programming keys (like reading the eeprom files in the ECU).
Some people attempt to program their keys on their own using these tools. However it's best to leave this task to an expert auto locksmith. If you're not aware of all the aspects of the various software systems, it's very easy to accidentally alter settings that could damage the vehicle. The most important thing to remember is that a professional with experience can assist you in avoiding these problems.
On-Board Programming
If your car is old enough to be considered old-fashioned, you'll have a key from the past to open the doors and turn off the ignition. Modern cars have transponder chips that need to be recognized by the computer system of the car in order to start. This is a further layer of security to keep thieves from stealing the car and driving away with a stolen vehicle. A certified locksmith will have the right tools and software to program a new key that will work with your car's security system.
The locksmith needs to purchase an uncut key that is compatible with the model and make of your car. Once your locksmith has the key, he'll connect the scanner for programming to the diagnostic port of your vehicle. This will place the car into an exclusive programming mode which will allow the locksmith to add a new key to the system.
The key scanner that is programmed communicates with the computer of the vehicle to send the code. The computer will detect the code and add it into the list of approved key. In some instances the scanner may also be able to remove keys that are stolen or lost from the system.
You can also program new keys with the EEPROM. It is more complex and requires an in-depth understanding of how electronic systems work. This is why it's best left to a professional that has extensive experience working on these types of systems.
Locksmiths can program keys quickly using onboard programming. If everything is done properly, it can take as little as one minute. If the key is not in good working order or the procedure isn't followed exactly, the process can take up to half an hour.
There are a variety of key programmer scanners that support different vehicle models and brands. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due their broad range of vehicle models. No system can program every vehicle. Additionally, these devices cost a lot. It's a good idea to purchase a programer that is updated regularly as the manufacturer develops new technologies. Your programming machine will quickly become obsolete if you don't do this.
