Mortise cylinder and rim cylinder are both cylinders in door locks, and superficially they are very similar. However, in reality, they are different. In today’s guide, we will discuss in detail the differences between mortise cylinders and rim cylinders. If you’re wondering about this too, read on to learn more.
A Mortise cylinder is a type of lock cylinder, usually used in a mortise lock. A Mortise cylinder is just a hardware accessory that is usually used with a door lock that has a threaded exterior and a cam. The main function of this matching door lock is to facilitate the user to lock and ensure the user’s home safety. The threads on the outside of the Mortise cylinder are primarily for screwing into other manufacturers’ mortise lock boxes. A cam on the back of the cylinder operates the locking mechanism and a set screw holds the mortise cylinder in place. When you insert the correct key into the mortise cylinder and turn it, the gears in the mortise cylinder will turn, unlocking the door.

Likewise, a rim cylinder is a type of lock cylinder, often used in rim locks. A rim cylinder is the mechanical and functional part of a standard lock cylinder and consists of a lock cylinder that can be rekeyed by a professional locksmith. Rim cylinders can incorporate a variety of different locking mechanisms, but the most common include chip cylinder locks, pin cylinder locks, and disc cylinder locks. The rim cylinder is specially installed on the night lock on the exterior door.
They are designed to be opened from the outside with a key and operated by a lever on the inside. When you encounter special circumstances (such as theft), you can quickly replace the rim cylinder in the rim lock to ensure your safety.
Next, iLockey will compare the mortise cylinder and rim cylinder from different aspects.
The mortise lock and rim lock, which are composed of mortise cylinder and rim cylinder respectively, are different in design features.
Smooth appearance: The metal on the outside of the Rim cylinder is smooth and flat, and there is no threaded appearance. So you’ll need to use long screws or mounting bolts to secure it to the door surface. This requires you to slide in the lock from the front, and tighten the bolt from the other side of the door. Without these two screws, the cylinder would slide off the door. In addition, due to the smooth cylinder shape of the Rim cylinder, suppliers should use custom paper tube packaging to protect Rim cylinder parts from damage during transportation.
Locking Rod: The back of the Rim cylinder has a short piece of metal rod that doesn’t sit flat against the back of the cylinder. You use the correct key to turn the stem through the door to unlock the device by turning the stem.
Outer Lock Body: Rim locks are designed with a rod and bolt protruding into the door. As a result, the Mortise cylinder looks like it sinks into the door when secured, while the Rim cylinder protrudes out. This could be in the form of an emergency bar, an exit bar, or some other form of external unit, of which the Rim cylinder fixture is the most common in commercial settings. The remaining forms are generally found in dwellings. To further illustrate what a panic lever is, it’s the horizontal length of metal that you push to open the door. A part of the metal will be depressed (like a big button) which will retract the latch and allow the door to open freely. The biggest difference is that one is inside the lock and one is outside the lock.

The locking mechanism of these two cylinders is also an important point of difference that you should be aware of. The locking system operates differently for rim locks and mortise locks. A mortise lock cylinder has a cam that rotates when the key is inserted. This triggers the lock. With a rim lock, as soon as the key is turned, the threaded rod turns to activate the lock. A mortise door lock actuates down from the inside of the door, while a rim cylinder actuates backward behind the door.
As we all know, the cost of an item is determined by many factors, including materials, functions, and labor costs. We mentioned above that the structure and installation of the mortise cylinder are very complicated, so the cost price of the mortise cylinder will be more expensive than the rim cylinder.
The structure and installation of the rim cylinder are simpler than the mortise cylinder, so overall, its cost will be lower.

A door lock is an essential part of any building as it secures the premises from unauthorized access. Door locks are simple mechanisms, consisting of two main parts, the lock and the key. The lock is the part that fastens the door, and the key is used to open it. However, in order for the lock to work, it needs a cylinder. But what is the purpose of the cylinder on a door lock?
The cylinder is the central part of the lock that receives the key and turns to release the bolt, allowing the door to open. The cylinder plays a crucial role in the operation of the lock, as it is the part that translates the key's unique shape, or code, into an instruction that releases the bolt.
There are several types of lock cylinders, each with its own advantages and disadvantages. The most common types of lock cylinders are pin tumbler, wafer tumbler, and disc tumbler.
Pin-tumbler cylinders are commonly found in residential and commercial locks. This type of cylinder has pins of varying lengths that correspond to the grooves in the key. When the key is inserted into the lock, the pins are lifted to the correct height, aligning them with the shear line, allowing the lock to turn.
Wafer-tumbler cylinders are commonly found in automobile locks. They use flat, thin wafers that move up and down to correspond with the grooves in the key. When the key is inserted into the lock, the wafers are lifted into place, aligning them with the shear line, allowing the lock to turn.
Disc-tumbler cylinders are commonly found in high-security locks. They use flat, rotating discs that interact with the key to allow the lock to turn. When the key is inserted into the lock, it pushes the discs into alignment with the shear line, allowing the lock to turn.
Another cylinder style is the eurolock cylinder, which is a type of lock that is often used on doors in European countries. It is easily recognizable as a lock that has a long, thin cylinder. Like other locks, it uses a key to operate the lock. The key is inserted into the eurolock cylinder, and when it is turned, it locks or unlocks the door.
Choosing the right type of lock cylinder is essential for ensuring that the lock on your door is as secure as possible. If you are unsure which type of lock cylinder is best for your needs, it is always best to contact a professional locksmith or a reputable supplier of lock cylinders. These experts can guide you through the process of selecting the right cylinder for your lock and help ensure that your door remains secure.
In conclusion, the purpose of the cylinder on a door lock is crucial, as it is the part that receives the key and turns to release the bolt, allowing the door to open. There are several types of lock cylinders available, including pin tumbler, wafer tumbler, and disc tumbler. The eurolock cylinder is often used on doors in European countries, and it is easily recognizable as a lock with a long, thin cylinder. If you need assistance in selecting the right lock cylinder for your needs, be sure to contact a professional locksmith or a reputable supplier of lock cylinders.
