The key difference between house keys lies in the specific keyhole they are designed to operate. Each key and lock mechanism has its own unique code, ensuring that only the correct key can unlock or lock a particular door.
When you buy a new door, it usually comes with a couple of keys that match the lock set. Your insurance company might also have certain security requirements that you’ll need to meet when selecting the most secure type of key or lock. If you ever need extra keys, you can always order more.
Common Types of House keys
At first glance, house keys might all look the same, but a closer look shows that they are actually quite different.
There are many types of house keys, each designed to work with a specific keyhole, providing its own level of security. While the differences between house keys may seem small, they are important.
In this article, we’ll clear up any confusion by exploring the 12 types of house keys commonly found on the market.
1. Traditional Flat Key
The traditional flat key is probably what comes to mind when you think of a house key. It’s a single-sided key with a series of ridges that match the pins inside a standard pin-tumbler lock.
Despite its simplicity, this key has been the backbone of home security for decades. However, its straightforward design also makes it easier to pick, which is something to consider if you’re looking for maximum security.
2. Double-Sided Key
2. Double-Sided KeyA step up from the traditional flat key is the double-sided house keys, which features ridges on both sides. This design provides a bit more security because it’s harder to pick than a single-sided key.
Double-sided keys are often used for deadbolts and other high-security locks, making them a good choice for exterior doors.
3. Four-Sided Key
The four-sided house keys takes the concept of the double-sided key even further. As the name suggests, it has cuts on all four sides, making it even more challenging for would-be intruders to pick the lock.
This key is often used in high-security locks and offers a good balance between cost and protection.
4. Tubular Key
4. Tubular KeyTubular keys are instantly recognizable by their cylindrical shape. Often used in vending machines, bike locks, and some high-security door locks, these keys are much harder to pick due to their unique design.
If you’re looking for an option that offers more security than the average house key, a tubular key could be worth considering.
5. Paracentric Key
Paracentric keys are a type of skeleton key with a more complex design. They feature an asymmetrical blade that requires a special lock mechanism to operate.
Paracentric keys are usually found in prisons and high-security facilities, but they can also be used in residential settings where maximum security is needed.
6. Dimple Key
6. Dimple KeyThe dimple house keys is a more modern take on traditional keys. Instead of the typical ridges, it has a series of dimples or indentations on its surface.
These dimples align with pins in the lock, providing a higher level of security. Dimple keys are often used in Europe and are gaining popularity in other parts of the world due to their durability and security.
7. Skeleton Key
Skeleton keys are often associated with old, historic homes. These house keys are designed to work with multiple locks, particularly warded locks, which are now largely obsolete.
While they are not commonly used today, some older homes may still have locks that use skeleton keys. They also make great collectibles or conversation pieces.
8. Keycard
8. KeycardKeycards are flat, rectangular cards often used in hotels, office buildings, and modern homes. They operate using electronic locks and are a staple in keyless entry systems.
Keycards house keys are convenient and eliminate the need for traditional keys, but they do require electronic systems to function.
9. Magnetic Key
Magnetic keys work by using magnets to align pins inside the lock. They offer a good level of security and are usually found in high-security environments, such as government buildings or secure facilities.

11. Restricted Key
Restricted keys are designed to provide an additional layer of security by limiting who can make copies.
These house keys are usually patent-protected, meaning only authorized locksmiths can duplicate them.

12. Laser-Cut Key
Laser-cut keys, also known as sidewinder keys, have intricate cuts on both sides, making them difficult to duplicate and pick.
These house keys are often used in high-end vehicles, but they are also suitable for home locks that require higher security.
Factors to Consider when Choosing a House
When choosing a house key, it’s essential to consider several factors to ensure that your choice meets your security needs, budget, and convenience. Here are the key factors to keep in mind:
1. Security Level: The security of your key is directly related to the type of lock it operates. High-security locks, like those that use restricted or laser-cut keys, are harder to pick or duplicate.
Some keys, like restricted keys, cannot be easily duplicated, adding an extra layer of security.
2. Durability: Keys made from durable materials like brass or steel are less likely to wear down over time.
Keys with complex designs, such as four-sided or dimple keys, often offer better longevity.
3. Compatibility: Ensure that the key you choose is compatible with your current locks, or be prepared to upgrade your locks to match a new type of key.
If you have or plan to use smart home systems, consider keys like smart keys that can integrate with these technologies.
4. Convenience: Consider how easy it is to use the key, especially if you have specific needs, such as easy access for children or elderly family members. Bulky keys or those with unusual shapes may be inconvenient to carry.
5. Cost: High-security keys like laser-cut or magnetic keys are more expensive upfront compared to traditional flat keys.
Consider the cost of duplicating or replacing the key. Some keys require specialized equipment for duplication, which can add to the cost.
6. Potential for Future Upgrades:If you plan to upgrade your security system in the future, consider whether the key type you choose will be compatible with new technologies or locks.
7. Aesthetic Considerations: Some people prefer keys that match the style of their home, especially if the key or lock is visible.
8. Legal and Patent Restrictions: Some keys are protected by patents, meaning only authorized locksmiths can duplicate them. This adds security but can be less convenient if you lose a key.
Choosing the right house key is about balancing your need for security, convenience, and cost. Whether you opt for a traditional flat key, a modern smart key, or something in between, understanding the strengths and weaknesses of each type can help you make an informed decision.
As you consider your options, think about your specific needs, the level of security you require, and your budget.
