Understanding the Different Types of Car Keys

Not so long ago the loss of car keys wasn't an issue. In fact, you could find a spare at an auto parts store or at your local locksmith.

As car key and repair have evolved to accommodate technological advances replacement of keys that have been lost is more difficult and expensive. Find out more about the elements that affect the cost of a replacement car key.

Basic Keys

When we think of our car keys, they often think of a simple metal key that opens doors and turns on the engine. While these are the most common types of car keys however, there are other kinds that are more sophisticated and have enhanced security features. Knowing the distinctions between different types of keys for cars can help people know what to expect when replacing or fixing the keys.





Keys that are standard are the most basic kind of car key. They've been around for many years, and remain the most popular option for newer vehicles. These are the keys you can purchase at a hardware store and hook to your keychain. Keys that are standard can be copied at a relatively low cost, but they are expensive to replace when lost or damaged.

Modern alternatives include the transponder key which has been used since 1995 and provides an extra secure option than traditional keys. Microchips are incorporated into the handle of the key and activated when the key is inserted into the ignition. They are more expensive to replace in the event that they become damaged or lost, but offer better protection against theft than conventional keys.

Another option is the switchblade key, which folds into the form of a key fob when in use. They are more expensive than regular keys to replace, but they are more expensive when the shank of the key or the handle is damaged.

Additionally, there are the smart keys that have built-in Bluetooth trackers as well as remote starts. These are more expensive than standard keys, and may require a locksmith's specific tools to repair.

Mechanical Keys

In the past when you lost a car key or it stopped working out of the blue, all you had to do was go to your local hardware store and get a replacement. Today things are more complicated. There are several types of cars in circulation and each one has its own key. Depending on its type, it could cost more or less than 50 dollars.

key repair are the most basic type. They're also referred to as "insert-and-turn" keys. These keys were the ones you could buy from the hardware shop for a few cents. They don't have a transponder inside them and are used to lock the door or trunk locks, but not to start the car.

The transponder key is the other type that is frequently used. It has a tiny transponder inside the head of the key which transmits a coded signal to the ignition system of your car to verify the legitimacy of the key. This system was introduced in vehicles as early as 1995. It protects them from being started with an unauthorised key or a lost one.

To fix this kind of key the first step is to identify what is causing it to malfunction. In most cases it is a problem with the cap on the key or switch is the cause. To fix the problem, the key cap or key switch must be removed with an instrument. They will then need to be cleaned and lubricated. Lubricating the switch is important since it can eliminate issues like key chatter. This is a reference to keys which can register multiple inputs when they are they are pressed.

Transponder Keys

Transponder keys, also referred to as "chip keys" are an integral part of the anti-theft system in your vehicle. The small microchip embedded inside the plastic head of the car key sends the signal to the antenna ring surrounding the ignition cylinder. If the computer in the car doesn't receive the correct response from the transponder, it won't begin to turn on. This type of chip is found in most cars manufactured since 1998.

The issue is that the same thing that makes these types of keys more secure also makes them more expensive to replace. They are not only different from conventional mechanical keys in terms of design and appearance, but they also include a microchip that needs to be programmed into the computer of the vehicle in order to function.

Connecting a diagnostic tool with the computer in your car, and then entering the programming mode is the way to accomplish this. This procedure can be more complicated than simply cutting a blank and because these tools aren't widely available in all locksmith shops, you may pay more than if you were to replace the mechanical key.

Another consideration is the make and model of your vehicle. Certain manufacturers have their own specialized equipment that needs to be used to program their vehicles, which will increase the cost.

Some people prefer having professionals handle the programming of their transponder keys. This is due to the complicated procedures, like cutting wires to remove the transponder's antenna, and using a scanner device and the peace of mind that comes from knowing that a professional is working on your car. It is possible to save money by going directly to the dealership to have your new chip installed.

Keys Laser Cut Keys

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

This technology does prevent car thefts, however it's not able to stop them entirely. The key's unique blade and shape is difficult to duplicate, however a burglar with the right tools and equipment can still make use of it to gain access into your car. This is because traditional keys have the standard lock cylinder, which is easy to pick. However, laser keys have a sidewinder lock cylinder, which is much more resistant to picking.

The key is also more durable in comparison to traditional keys. The blade is constructed of hardened steel and can endure wear and tear for a long period before it begins to wear out. If the key is damaged or wears out, it's affordable to have it repaired by a locksmith.

Laser-cut keys are more expensive however they are more secure. The combination of the blade, the transponder and the lock makes it harder to duplicate. However, they're vulnerable to being lost or stolen if you do not take the necessary security measures to ensure their safety.

Key Fobs

While they're handy, key fobs can be difficult to use. They don't hold a charge for long, and they're likely to cease functioning when you least expect it. You could find yourself in a compromising situation if your fob malfunctions particularly when you are loading up your trunk with groceries or heading to work after a long and tiring day. It's possible to call for locksmith services or a tow truck and it could cost a lot to get your vehicle back on the road.

The type of key used and the materials used in the fob could affect the cost. It also depends on the brand which is usually more expensive. Some fobs can be programmed by the owner, while others require a dealer reprogram them to the vehicle.

If your key fob does not work or is working infrequently, a new battery may be the solution. The coin-shaped batteries can be found at hardware stores, online retailers and big box retailers for less than $10. To replace the battery, gently break off the two halves of your key fob and then insert the new one with the same orientation.

It's up to your dealer reprogramme it if your key fob has been damaged or is not functioning as it should. You can do it yourself, but it's preferential to leave it to a professional to avoid accidental damage that could lead to expensive repairs in the future. If you have spare keys and fob, you can bypass this step and buy a replacement to save money. If you've lost both your keys and fob it's worth the cost to have a dealer reprogram the new key and cut the new key at the same time.
