What is Laser Cut Keys?

Laser cut keys are also known as sidewinder keys, internal cut keys, or high security keys. They have a flat metal blade with a wavy groove cut along one or both sides of the key. The groove is cut by a laser machine that follows a precise pattern based on the key code of the car. The key code is a series of numbers and letters that corresponds to the groove pattern of the key. The groove acts as a unique identifier for the car’s ignition system and door locks. Laser cut keys are harder to duplicate and pick than regular keys, as they require a specialized equipment and skill.

Laser cut keys are not new, but they have become more popular in recent years. Many car manufacturers have switched to laser cut keys for their newer models, as they provide more security and convenience for the car owners. Some of the car brands that use laser cut keys include Audi, BMW, Honda, Hyundai, Lexus, Mercedes-Benz, Volkswagen, and Volvo.

How are Laser Cut Keys Made?

A professional locksmith or a car dealer who has access to a laser key cutting machine and the key code of the car can make laser cut keys. The original key, the car manual, the door lock, or the car’s computer system may have the key code. The locksmith or the dealer enters the key code into the laser key cutting machine, which then cuts the groove on a blank key using a high-powered laser beam. The process takes only a few minutes and produces a perfectly matched and smooth key.

However, making a laser cut key is not as simple as it sounds. Laser cut keys require more expertise and programming than regular keys, as they have a transponder chip embedded in the key head that communicates with the car’s immobilizer system. The immobilizer system is a security feature that prevents the car from starting if the key is not recognized. The transponder chip has a unique code that matches the code of the car. The locksmith or the dealer has to program the chip using a diagnostic tool that connects to the car’s computer system. This adds an extra layer of protection and complexity to the laser cut key.

Some Tips and Warnings:

Tip 1.

Do not try to make a laser cut key yourself, unless you have the proper equipment and skill. You may end up damaging the key or the lock or voiding the warranty of your car.

Tips 2.

Do not use a regular key cutting machine to make a laser cut key, as it will not be able to cut the groove accurately and smoothly. You may end up with a key that does not fit or work properly.

Tip 3.

Do not lose or damage your original laser cut key, as it will be harder and more expensive to replace or duplicate. You may need to provide proof of ownership and identity to get a new key.

How to Replace or Duplicate Laser Cut Keys

If you lose your laser cut key or it gets damaged, you may wonder how to get a new one. Replacing or duplicating a laser cut key is not as easy and cheap as replacing or duplicating a regular key. You should be well aware of the process of laser cut keys to prevent any loss. You have three main options: going to a dealer, going to a locksmith, or doing it yourself.

Going to a dealer:

This is the most expensive and time-consuming option, as dealers charge a high fee for making and programming a laser cut key. If you do not have a spare key, the dealer may take several days or weeks to deliver the key or you may have to tow your car to them. However, this option guarantees that you will get a genuine and quality key that works perfectly with your car.

Going to a locksmith:

This is the most convenient and affordable option, as locksmiths charge a lower fee for making and programming a laser cut key. You can also get the key on the same day or within a few hours or call a mobile locksmith to come to your location if you do not have a spare key. However, this option requires that you find a reputable and experienced locksmith. One should have necessary equipment and the access to the key code of your car.

Doing it yourself:

This is the riskiest and challenging option, as it involves buying a blank key and a programming tool online and following the instructions to make and program the key yourself. You may save some money and time. But you may also end up with a key that does not work or damages your car. This option is not recommended unless you have the proper knowledge and skill.

Some Suggestions and Recommendations:

Here is a detailed table about some suggestions and recommendation that are very essential for one to know before replacement of laser cut keys.  Let’s check this table and avoid any loss or any incident.

Look for a reputable and reliable locksmith that has experience with laser cut keys. Ask for a written estimate and a warranty for the service.
Make sure you have the necessary information and documents to prove your ownership of the car. Laser cut keys are high-security keys that require programming and verification to work with your car.
