Aluminum door locks are famous as the most robust, solid locks for commercial and residential properties. One of the best benefits of these locks is their high resistance to rust and corrosion. Keep reading to learn about different types, repair options, installation tips, and more.

Aluminum Door Lock Types

Aluminum door locks come in various styles, each with features and benefits. Here are the most popular options.

Mortise Locks

A mortice lock is a mechanism commonly used indoors, like on the entrance or interior doors of commercial or residential properties requiring a high level of security. The mortice lock is typically placed into a recessed area cut out of the door. It consists of a mechanism, a lock cylinder that controls the door locking and unlocking, and a key that opens the lock.
Mortise locks are known for their complex mechanisms, durability, and the use of high-quality materials that can withstand use over time.

Deadbolt Locks: One of the Best Secure Options for an Aluminum Door Lock

Deadbolt locks require a key or a thumb turn to operate. It provides dependable security because it cannot be easily unlocked with a knife or a credit card. Installing a deadbolt lock on solid steel, wood, or fiberglass doors is always advised for maximum security because these doors cannot be readily jimmied open.

Generally, there are two main types of deadbolt locks:

Single-cylinder:

This model is activated with a key on the exterior door side and a thumb-turn piece on the interior side. Pay attention to the fact that this lock should be installed where there is no breakage glass within 40 inches of the thumb turn, as intruders can easily break the glass, reach the inside, and turn the thumbpiece.

Double-cylinder:

This model consists of keyed cylinders on both sides, meaning you need a key to lock or unlock it from both sides. It should be installed in the glass within 40 inches of the lock. Always remember to leave a key near the safety when someone is home, as double-cylinder locks can prevent escape from a burning house.

Handle Sets

A handle set is a distinctive aluminum door lock option virtually solely utilized for the main entry doors.

Handle sets have a more distinct and conspicuous form since they serve both a cosmetic and a security function.


Most handle sets are lengthy, with the keyed deadbolt lying above the handle as a single piece or split apart. The handle component of this hardware often contains a thumb lever or button to release the latch from the door frame.


The keyed deadbolt rests above the handle in most handle sets, either as a single piece or separately. This hardware's handle piece typically incorporates a thumb lever or button to disengage the door frame latch.

FAQ

Can a door lock cylinder be repaired?

Yes, although it greatly depends on the extent and type of damage. A locksmith can fix minor damage (such as a jammed lock or a loose cylinder) by rekeying the cylinder or tightening any loose parts. In other circumstances, the locksmith may advise you to replace specific components, such as pins or springs, to restore them to proper functioning order.

However, if the damage is severe, such as a cracked or fractured cylinder, you should generally replace the complete cylinder because a damaged cylinder can undermine security.

Additionally, attempting to repair a severely damaged cylinder may not be cost-effective or reliable in the long term. In these cases, consult a professional locksmith to determine the best action for repairing or replacing the door lock cylinder.

How do you cut a lock hole in an aluminum door?

  • Step 1. Measure and mark the lock hole location on the door.
  • Step 2. Use a center punch to make an indentation in the center of the marked area. It will help guide the drill bit.
  • Step 3. Use a hole saw drill bit to drill a spot at the marked location. Apply slow and steady pressure to prevent the drill bit from wandering or damaging the aluminum.
  • Step 4. After drilling the hole, use a jigsaw to carefully cut out the lock hole, following the marked lines. Be sure to file down any rough edges or burrs on the spot to ensure a smooth and secure fit for the lock.

Finally, remember to follow safety precautions and wear eye and ear protection while cutting the hole.

What type of lock on the aluminum door is proper?

The appropriate lock type is determined by various criteria, including the desired level of security, the kind of door, and personal preferences.

Deadbolts and smart locks, in general, are reasonable solutions for locking an aluminum door since they give high levels of security and are frequently compatible with aluminum door frames. A deadbolt is a strong lock that cannot be opened with a credit card or other flexible tools, making it a dependable choice for door security.

Smart locks, which can be locked and opened remotely and integrated with other smart home devices, are another option that provides increased convenience and flexibility.

Finally, your specific needs and tastes determine the best lock for you.
