Understanding the Different Types of Car Keys

In the past, misplacing-or worse, losing-your car keys was not a big deal. In fact, you could probably find a spare at an auto parts shop or even your local locksmith.

Since cars have been upgraded to adapt to technological advances replacing keys lost in the car is becoming more difficult and costly. Learn more about the variables that impact the cost of a replacement car key.

Basic Keys

When people think of their car keys, they may think of a basic metal key that can open doors and start the engine. While these are the most popular kinds of keys for cars but there are a variety of kinds that are more advanced and offer enhanced security features. Understanding the differences between various kinds of car keys can help people know what to anticipate when replacing or repairing keys.

One of the most basic types of keys for cars is a standard one, that has been in use for decades and remains the most common option for newer cars. These are the keys you can purchase from an establishment that sells hardware and attach to your keychain. Keys that are standard are fairly affordable to duplicate, but could cost a lot to replace when they're damaged or lost.

Transponder keys are a modern alternative that has been in use since 1995. They are security and are more secure than traditional keys. They are equipped with microchips inside the key handle and are activated when inserted into the ignition. They are more costly to replace in the event of a damage or loss, but they are more secure against theft than traditional keys.

Another alternative is the switchblade that folds down into a key fob when not in use. They are more expensive than regular keys, but they may cost more in the event that the shank of the key or the handle are damaged.

There are also smart keys that have built-in Bluetooth trackers, as well as remote starters. They are more expensive than standard keys and could require a locksmith's special tools to repair.

Mechanical Keys

In the old days when you lost a car key or it stopped working out of the sudden, all you needed to do was head to the local hardware store and find an alternative. The process is a bit more complicated in the present. There are a variety of cars in circulation and each has a different key. Based on the model, replacing it may cost you more or less than $50.

Mechanical keys, also referred to as "insert and turn" keys are the simplest type. They are the keys that you used to be in a position to replace at the hardware store for pocket change. They don't have a transponder inside them and are used to lock the trunk or door locks, but not for starting the car.

The other type of key, which is the most common in use is the transponder key. This key has an internal transponder within the head that transmits a coded signal the ignition system in your car to verify that the key is legitimate. The system was put in vehicles from 1995 onwards. It prevents the ignition from being started using an unauthorized key or a lost one.

To fix this type of key, the first step is to identify the reason for its malfunction. In the majority of cases, a problem with either the key cap or key switch is the culprit. To fix this issue, the key cap and key switch must be removed carefully using tools, then cleaned and lubricated to resolve the issue. Lubricating the switch on the key is essential as this can help to eliminate issues such as key chatter, which refers to keys that register multiple inputs each press.

Transponder Keys

Transponder keys (also called "chip" keys) are an essential part of your car's anti-theft system. The microchip inside the plastic head of the car key sends the signal to the antenna ring that surrounds the ignition cylinder. If the computer of the car isn't receiving the correct response from the transponder, it won't start. The majority of cars manufactured from 1998 include this type of chip.

The problem is, the same thing that makes these types of keys more secure also makes them more expensive to replace. In addition to having distinct design from traditional mechanical keys, they also contain a special microchip that needs to be programmed into the computer in your vehicle to work correctly.

Connecting a diagnostic device to your car's computer and then entering the programming mode is how you accomplish this. This process can be more complicated than cutting a blank, because these devices aren't widely available in all locksmith shops, you could have to pay more than if were to replace the mechanical key.

The make and model of your vehicle is an additional aspect. Certain manufacturers have their own equipment that needs to be used to program their vehicles, which can increase your cost.

Some people prefer that professional programming of their transponder keys. This is due to the complex procedures involved, such as cutting wires to disconnect the transponder antenna, and using a scanning device as well as the peace of mind that comes with knowing you are working with a professional who is experienced on your vehicle. You could save money by going directly to the dealership to get your new chip installed.

Laser Cut Keys

Laser cut keys are a form of car key that comes with a high-security blade. They were introduced in the 1990s to combat vehicle theft. They are much harder to duplicate than traditional keys and have transponder chips inside their heads. The chips communicate with the ignition when inserted into it, preventing the vehicle from starting in the event that the wrong key is used.

While this technology works to stop car thieves from entering your home however, it isn't able to stop them completely. The unique blade and design of the key is difficult to duplicate, but a burglar can still use it with the appropriate tools to gain entry to your vehicle. This is because traditional keys have the standard lock cylinder, which is easy to pick. Laser keys, however, come with a sidewinder cylinder lock that is much more difficult to pick.

The design of the key is more durable than conventional keys. The blade is composed of hardened steel and can endure wear and tear for a long period before it begins to wear out. If the key breaks or wears out, it is affordable to have it repaired by a locksmith.

Laser-cut keys are more expensive, but they offer greater security. The combination of the blade, the transponder and the lock makes it harder to duplicate. However, you can try this out are still vulnerable to being lost or stolen if you do not take the necessary security measures to ensure their safety.

Key Fobs

Key fobs are not always reliable even though they're practical. They won't last forever and tend to stop functioning when you most likely don't. You may find yourself in an embarrassing situation if your device fails in the middle of taking your trunk full of groceries or going to work after a tiring day. You may have to call a locksmith or a tow truck, and it could cost you a considerable amount to get your car back on the road.





Many factors influence the cost of a fob, such as the type of key it is made of and the materials it is made of. Brands are also an important factor in that they can be more expensive. Some fobs can be programmed by the owner, while others require a dealer to reprogram them to the vehicle.

If your key fob does not work or works intermittently, a replacement battery could be the answer. The coin-shaped batteries usually cost $10 or less and are available at hardware stores and big box retailers and on the internet. To replace the battery, gently pull the two parts of the key fob and then insert the new one in the same way as the previous one.

If your key fob is damaged or isn't functioning correctly, you'll need to have it reprogrammed by the dealer. You can do this yourself, but it's best to let it be done by a professional to avoid any accidental damage that could lead to costly repairs in the future. If you have a spare key and fob, you could skip this step and buy a replacement to save money. If, however, you've lost both fob and keys, it's worth the extra cost to have a dealer reprogram the new key and cut the new key at the same time.
