The short answer is that a locksmith uses all of the same tools and methods that a car mechanic, machinist, or mechanic would create a function key for your car. The main difference is that locksmiths work with metals and other components instead of engines.
A car lock is definitely not the kind of thing you let an amateur play with. Car locks are very sensitive, and new models have programmed keys. The locksmith has to be very careful when handling old keys and programming new ones.
Locksmiths have to use a CNC machine (computerized numerical control) for dealing with cars, especially automated vehicles. This computerized machine can cut, heat, and melt metals so that the locksmith’s service tools can create an exact copy of your key. There are few steps of making a car key that the locksmith is required to follow.
Replacement Of The Lost Key
Cutting Vehicle Keys
Programming Car Key Fobs
Tracking the Key Code
To create a key that will match your current car, a locksmith will track your key code. A locksmith will usually have to use a scanner to scan the car’s computer and check the memory for your key code to get the key code. This is generally done using a special programming machine that is connected directly to the car. If this is done correctly, your car will start immediately (without an additional copy of your key). If you require an extra copy of a key instead, you may pay much more than expected.
Key-Cutting Process
An experienced locksmith will use a key cutting machine that takes certain information, such as the type of vehicle, and creates an appropriate critical template for that vehicle. An accurate, high-performance key cutting machine will do the job. The locksmith moves the cutting head and metal parts to create each drawing so that the locksmith moves, not the machine, as most people mistakenly believe. The locksmith then uses a machine tool to bend the cutting edge of the key. The process is completed by drilling holes on both sides of the key and filling this space with small pieces. As with the key cutting machine, the locksmith will use the key on the cutting surface to make a copy.
The key, which is now identical to the original, can be used in any vehicle equipped with these special keys and locks.
Programming the Key
It is a critical task in a car key process. The locksmith must connect the programming device to the EWS connector port of your vehicle and turn the ignition on. Then they can send commands to your vehicle. These commands are sent via not only OBD2 but also on a different channel, specific to each carmaker. After that, the car will respond with a series of diagnostic codes. With that information, a locksmith can determine if there is a problem with your key (bad code), ignition (bad connection), or both. The good news is that this information makes it easier for the professional to fix the problem. All locksmiths have to do is replace the ignition cylinder or reprogram your blank transponder chip. Then they can use the programming tool again and reprogram the actual key (which has now been fixed).
Using Scoping to Make A New Key
This process is used when a locksmith needs to make a key for a specific vehicle. The locks are called push-to-start that provide keyless entry, but they’re also locationally unique. The modern locks of today are typically equipped with a remote starter and proximity unlock, which allows owners to carry out a start-up procedure by merely inserting a key fob.
To begin creating a blank key, the locksmith will need to measure the space of the lock cylinder on your vehicle. This measurement should be precise and requires special tools, such as an electronic distance measuring device or the appropriate space finder. The locksmith will then create a pattern file after removing the existing key from your vehicle. The patterns include all information to make any keys that fit in your vehicle’s lock cylinder. The locksmith can then use the same lock cylinder and the information given to create the key.
