Plastic door lock mechanism

Types of Plastic Door Lock Mechanism

A plastic door lock mechanism comes in different types to suit various needs. Here are some of them:

• Deadbolts

  Plastic deadbolt locks are usually used in residential settings. They offer a higher level of security compared to other locks. Deadbolts are called so because they don't have any springs. To unlock them, one has to twist an oval-shaped knob from the inside and use a key from the outside. Since they are not spring-loaded, it is almost impossible for intruders to unlock them forcefully.

• Knob Locks

  Plastic knob locks are some of the most common types of door locks. They get their name from the circular lock body that resembles a doorknob. These locks are usually installed on exterior doors. A key is used to lock or unlock the lock from the outside. On the other hand, a key or a thumb turn is used from the inside to lock or unlock the knob lock.

• Lever Handle Locks

  Lever handle locks are quite similar to knob locks. The only difference is that these ones use a lever handle to open and close the door. They are more convenient for people with disabilities and elderly people. Just like knob locks, lever handle locks are available in different designs. Some of them are designed to be locked using a key from the outside, while others can be locked using a thumb turn from the inside.

• Electric Strike Locks

  These are plastic door lock mechanisms that are commonly used in access control systems. They are electrically powered locks that work with a panic bar or a push button. When prompted, the strike lock receives a signal and releases the latch bolt.

• Deadlatch Locks

  Plastic deadlatch locks combine plastic deadbolts and spring-loaded bolt locks. They are usually installed on doors that are frequently accessed, such as back doors. These locks automatically latch close when one pushes the door against the frame. They are usually locked using a key from the outside or a turn knob from the inside.

• Mortise Locks

  Mortise locks are designed for plastic door lock mechanisms that are installed on a door frame. They are very complex locks and require a skilled locksmith to install them. Mortise locks come in different styles, including deadbolts and lever handle locks.

• Cam Locks

  Plastic cam locks are simple locks that are made up of a cylinder and a cam. They are usually installed on cabinets, mailboxes, and other furniture. To lock or unlock a cam lock, one has to rotate the key hole. The cam rotates and moves out of the opening or into it to lock or unlock, respectively.

Specification and maintenance of plastic door lock mechanisms

The specifications of locks with plastic parts vary depending on the type of lock and the manufacturer. Here are some general specifications to look out for:

• Lock type:

  There are different types of plastic door lock mechanisms as discussed earlier. Each type has its own way of functioning and offers a different level of security. For example, a deadbolt lock offers more security than a spring latch lock.

• Security level:

  Consider the security level of the lock. For deadbolt locks, the security level is rated from 1 to 3. Level 1 is for residential use while level 3 is for high security commercial use. Level 3 deadbolt locks are hard to penetrate.

• Keying options:

  Some plastic door lock mechanisms have different keying options. For instance, they can be keyed alike or have a master keying system. Keyed alike locks open using the same key while master keyed locks are opened using a master key and other individual keys.

• Material:

  Plastic door lock mechanisms are made from different materials. Each material offers a different level of durability. Popular materials used include ABS plastic, nylon and polycarbonate. ABS plastic is the most common material used in door locks because of its durability and affordability.

Maintaining plastic locks is an important part of ensuring their longevity and effectiveness. Here are some maintenance tips for door locks with plastic parts:

• Keep the locks clean: A dirty door lock can cause a lot of problems. Clean the door locks regularly using a damp cloth to remove dust and debris. This will prevent dirt from entering the locking mechanism and causing jams.
• Lubrication: Lubricate the door locks regularly using a graphite lubricant or silicone spray. This ensures the locking mechanism parts move smoothly. Do not use oil-based lubricants because they attract dust and debris.
• Check for wear and tear: Inspect the door locks occasionally to check for signs of damage. If there are any damaged parts, replace them immediately before they cause the lock to malfunction.
• Protect the lock: Plastic locks are vulnerable to attacks by lock picking and bumping. Install security cameras to deter burglars from attempting to break into the premises through the doors. A door lock reinforcement is also a great way to protect the door lock from tampering.

How to Choose Plastic Door Lock Mechanism

Choosing the right plastic door lock mechanism can be a crucial decision. Here are some factors that should be considered before selecting a plastic door lock mechanism.

• Security Level

  The security level of a door lock is important. Depending on the level of security needed, choose a lock with a suitable security level. A more secure lock will have advanced features and a lower risk of being broken into.

• Quality and Reliability

  Quality and reliability should also be considered when choosing a plastic door lock mechanism. Select a lock that has a reputation for being reliable and high-quality. This will ensure that the lock works well and is not faulty.

• Ease of Installation

  Consider the ease of installation. Some locks are easier to install than others. If the lock needs to be installed quickly or by someone without much experience, choose a lock that is simple to install with clear instructions.

• Cost

  Cost is also a factor to be considered when choosing a plastic door lock mechanism. Determine the budget and look for locks within that price range. Remember that very cheap locks may not be high quality, so choose a lock that is affordable but also of good quality.

• Type of Door

  The type of door should be considered when selecting a plastic door lock mechanism. Some locks are better for wooden doors, while others work well on metal or fiberglass doors. Choose a lock that is suitable for the material and type of door that needs to be locked.

• Additional Features

  Additional features should also be looked at. Some locks have extra features that make them better for certain situations. Features like keyless entry, adjustable latch size, or being pick-resistant can be useful and offer more convenience or security.

How to DIY and Replace Plastic Door Lock Mechanism

Replacing a plastic door lock mechanism can be accomplished with simple tools and a little DIY knowledge. Here are some general steps that can be followed:

• Find a suitable replacement lock mechanism. Ensure that the new lock matches the old one in size and function. A like-for-like mechanism is best.
• Make sure the door is open. This will allow for easy access, especially if any parts of the lock are difficult to access.
• Use a screwdriver to remove the screws holding the door handles in place. This will allow the handles to be removed and give access to the lock.
• After removing the handles, the screws holding the lock should be visible. Remove these screws and slide the lock out of the door.
• Fit the new lock into the space where the old one was. Secure it with screws. Then, test it to make sure it works before putting the handles back on.

It is advisable to consult the manufacturer's instructions for specific details on replacing a door lock, as each model may vary slightly.
