"Ask Me Anything": Ten Responses To Your Questions About Automotive Locksmith Key Programming
Automotive Locksmith Key ProgrammingModern cars require some type of key programming. Depending on the car's maker and model, the procedure can be as simple as onboard programming using a spare key that works or as complicated as OBD2 or EEPROM programming.
The majority of US and Asian auto manufacturers have a programming protocol that they share with auto tool makers, which means they can design tools or hardware for automotive locksmiths.
Transponder Chips
Most newer cars use what are called transponder chips to stop car theft. These are tiny computer microchips that emit radio waves at a low level. They have a unique serial number which authenticates your keys when you connect it to the ignition barrel. If your vehicle doesn't recognize the signal it will shut down. This technology has proven to be an enormous success in preventing theft of cars. It also saves many car owners a lot of money because they don't need to replace their cars.
The fundamental idea behind the transponder system is to make it difficult for thieves to start your car without a key. In the past, thieves would use the flat screwdriver to push the ignition switch of your car into the "on" mode, or wire it hot to bypass the system. These types of thefts have been dramatically reduced thanks to the introduction of the transponder chip.
When you place the transponder key in the ignition, the signal is picked up by an antenna that is hidden within the barrel. The antenna is programmed with the frequency of the chip in the key. The onboard computer of the car will then recognize the key as being valid and will allow fuel flow and power the starter to start the engine.
Some vehicles only recognize certain type of transponder chip depending on the manufacturer. This is why it is crucial to make sure that your automotive locksmith has the right equipment to program your car's key and fobs properly.
A good automotive locksmith should have a multi-vehicle key programming tool that is compatible with different models and car brands. This is a much more cost-effective approach than purchasing specific tools for each model of vehicle. There are also specially-designed key programming tools for automobiles that are only suitable for specific brands of vehicles, but these are less frequently used. The top automotive locksmiths have the tools needed to work on any vehicle. Make sure you choose a reliable company that is equipped with this type of equipment.
Key FOBs
Key FOBs are programmeable transponder chip devices that permit your vehicle to open doors and start the engine with the push of a button ignition. There are also buttons that you can push to activate features such as door locks, trunk release or control of the fuel flap. Certain fobs come with additional functions that can be controlled by the button presses like a "smart" key fob that lets you summon your car to parking spots that are tight similar to the Genesis GV60, Tesla or Genesis GV60.
You can program spare key fobs by yourself with the assistance of an instruction manual, however you'll need to call an automotive locksmith if yours has stopped functioning. A professional is better equipped to connect the computer of your vehicle to the OBD port under the steering wheel.
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 feature pseudo-random code generators, which generate a unique unlock code each time you press the button. This stops attackers from recording and replaying the unlock signal to gain access to your vehicle.
In many instances, you can purchase an alternative key fob from the dealership or another retailer and 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 share their key fob programming protocols with third-party companies who produce the tools locksmiths for auto use to program their customers' keys.
Certain aftermarket key fobs can be advertised as compatible with any vehicle. However, automotive locksmiths advise against using them since they are likely to work poorly or not 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 not working. This will save you money over the long term by avoiding expensive repairs or replacing the fobs.
Vehicle Manufacturers' Programming Tool

It must be programmed by a locksmith mechanic, or dealer to work. These key fobs are equipped with security features that prevent hot-wiring, like in a film. The car won't start if the keys are not correct.
These key fobs are more complex than the traditional mechanical key and are the reason you'll typically find them in the hands of a skilled, professional auto locksmith. The cost of a key fob may differ based on the vehicle model and the key type, 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 to make the process more complicated, these key fobs for cars use a special software system to communicate with the car's onboard computer. The software prevents unauthorized access by only permitting the key to function only if it's programmed to the car in question. This means that if you get your keys replaced, you'll have to have the new key fob programed to the car to function.
This is accomplished by using a tool for programming car keys that is compatible with the vehicle's brand. This tool allows the locksmith to connect to the onboard diagnostics port (OBD) in the vehicle and then enter an programming mode. Key programming tools can either be an inexpensive handheld device or a fancy one that can perform many things beyond key programming (like reading and cloning Eeprom files within the ECU).
Some people may try to program their keys themselves using these tools. However this should be left to an experienced auto locksmith. It's easy to make mistakes when using software systems if you aren't aware of the nuances. This could lead to damage.

You can also program new keys by using the EEPROM. It is more complicated and requires an in-depth understanding of how electronic systems function. This is why it's best left to a professional who has a lot of expertise working on these types of systems.
Locksmiths can program a key quickly using onboard programming. If everything is done properly it could take as little as one minute. However, if the key isn't placed in the proper condition or the procedure is not adhered to, it could take as long as a half hour.
There are many different key programmer scanners which can work with different models and makes of vehicles. Both the Smart Pro and Autel IM608 Pro have become very popular with locksmiths due to their wide range of models for vehicles. There is no system that can program every vehicle. Furthermore, these systems are quite expensive. It's a good idea purchase a computer that will get regular updates as the manufacturer releases new technologies.
