Laser cut keys were developed with security in mind. It's much more difficult to steal a vehicle that requires a laser cut key in the ignition. This is one reason you'll typically find this type of key associated with high-end vehicle models. The whole purpose of laser cut keys is to make your vehicle less vulnerable to theft. If you misplace your keys or your key fob, however, this security can come at a high cost of replacement. This article will help you understand the basics of laser cut keys.

How Do I Know if My Key is a Laser Cut Key?

You can tell by looking at a key whether it's a laser cut version. These keys are sometimes referred to as sidewinder or internal-cut keys. They are often thicker than traditional keys and instead of having a series of notches, laser cut keys feature a wavy indentation along the length of the key -- usually on both sides. This allows you to insert the key either way to start the vehicle. 

What Makes a Laser Cut Key So Secure?

Many laser cut keys are electronic -- meaning that even if the key is duplicated, unless the electronic chip is present, the car still won't start. While this makes unauthorized key duplication difficult, it also makes it harder for you to replace a lost key. Not every locksmith has the computerized technology to recreate laser cut keys, and even if they do, there is still the problem of adding the chip. Most car owners who need to replace this type of key or key fob do so through their car dealership, making replacement more expensive.

What Do I Do if I Lose My Laser Cut Key?

If you misplace your laser cut key, you have several options. The most economical alternative is to check with your local locksmith. If you live in a larger, metropolitan area, finding a locksmith who specializes in laser cut keys is possible. If you can't find a locksmith, you may be forced to buy your replacement key fob and key through a dealership. 

How Do They Make My New Key?

Laser cutting a key typically involved using a type of milling machine that's operated by computer. The programmer enters the information that's customized specifically to your make of key into the computer, which then guides the milling machine through the cut.

How Do I Keep Track of My Key?

Owners of vehicles that use laser cut keys are less vulnerable to loss through theft, but the hassle and expense of replacing this type of key when it's lost or stolen is significant. For this reason, it's good to have a system of checks and balances in place regarding how you handle your keys. You can help lower the risk of losing your keys by creating a routine that you follow until it becomes habit:

• Designate a special storage area such as a hook or basket beside your door that you use exclusively to house your key. Remind yourself every time you enter your home to deposit the key in its assigned spot. 
• Never lend your key to anyone. If you need to lend someone your house key, remove your car key from the chain first. 
• Take a moment every time you park to double check that you've removed the key from the ignition, then put it in the same place every time you exit your vehicle -- a designated pocket, purse compartment, or inside your wallet. 

It's much easier and affordable to keep track of an existing laser cut key than it is to replace one. Take care to know where yours is at all times.
