Best Outdoor Combination Lock

With all that is happening today, it is much better to be safe than sorry.

Millions of homes and businesses are being broken into, as well as lockers and storage rooms. So if you want to keep your property safe, it is important to use a reliable lock.

The Combination Outdoor Lock is a weather-resistant and durable lock that uses a combination code to be unlocked; it is a safer and more user-friendly approach to padlocks.

The Combination Lock

A combination lock is a locking device that uses a sequence of numbers or symbols to open the Lock.

You can enter the sequence using a rotating dial that interacts with several discs or cams and the locking mechanism to unlock the Lock.

You get three- and four-digit combination locks, of which the four-digit ones are the safest and usually the best for outdoor use.

  • How to Do Combination Locks Work – Most Combination Locks have numbered dials connected to an internal locking device to lock the padlock. Turning the dials to the correct number sequence will disengage the locking mechanism. Some Combination Locks have three number sequences, while most outdoor models have four. You also get Combination locks that have a keyed unlocking mechanism as well.
  • Key Locks VS Combination Locks – Keyed Locks do not have dials and still offer a superior level of security compared to combination locks unless a thief has a key or tool to pry it open. Combination Locks are ideal as you cannot lose the keys and will remember a combination easily. However, combination Locks are not as well protected against shimming as keyed locks.

Outdoor Combination Locks

So, what is the difference between outdoor and indoor combination Locks?

Well, most Combination Locks for outdoor use can also be used indoors. However, indoor-only combination locks should not be used outdoors.

Outdoor combination locks are weatherproof; they consist of materials that will not rust or deteriorate in the sun and are much more durable, with heavy-duty cut-resistant materials for protection against burglars.

  • Materials – Stainless steel is the most common material used for combination locks especially for outdoor locks. However, aluminum may also be used.
  • Combination Lock Size – Larger Combination Locks are generally heavier and more secure as they provide greater resistance against sawing and breaking off.
  • Shackle Securing Mechanism – Most Shackles have a double lock with springs. However, some may have steel balls at the joints between the shackle and body for more security.
  • Shackle Length – You will need to ensure that the combination lock’s shackle is the right length for the Lock you want to use it for. Whether for a chain or other types of closures. You do get regular-length and extra-length shackle designs in combination locks.
  • Outdoor Use – Many Combination Locks are suitable for outdoor and indoor use. They are durable and weather-resistant materials that will not rust or deteriorate when used outdoors.
  • Key and Combination Option – Some combination outdoor locks likewise offer a key option you can use to unlock the combination lock.
