What’s the Most Secure Type of Lock for a Double Door?

July 3, 2020

What type of lock is best for double doors in Colorado? There are a variety of considerations you’ll need to take into account when making your decision.

First, it’s important to be aware of the kinds of locks you’ll find on the market and how they differ from each other. Here’s a quick overview of some of the most common options:

  • Door knob locks: There are a couple main kinds of door knob locks: spring latch locks and dead latch locks. Dead latch locks are generally considered by industry specialists to be the more secure option of the two, but they’ll still provide only minimal levels of security. Typically, these will only be used for interior doors.
  • Dead bolt locks: Dead bolt locks also come in two main types: single-cylinder and double-cylinder dead bolt locks. These provide a much higher level of security than door knob locks, and the double-cylinder locks will give you the better security between the two. They’re difficult to break open and frequently used for exterior doors or for doors that lead into sensitive rooms or facilities.
  • Security strike plates: These are additional locks that get added onto the door frame to provide an additional level of security beyond the standard lock you’re already using. The strike plate features a heavy-duty metal that gets attached to the door frame and secured to a wall stud, making it extremely difficult for anyone to force their way through.

The best double door lock option

Selecting the proper lock for the double doors in your Colorado home depends on a variety of factors, including the material of the door. If you have a solid wooden door, you’re going to want double-cylinder deadbolt locks. These are the kinds of doors most likely to be installed at the entrance to a home, and thus you’ll want them to be secured. Chain hooks and gate style locks should not be used as locks on a front door, as they do not offer sufficient security.

A double-cylinder deadbolt lock will be keyed in on both sides of the lock. This means you’ll need a key to unlock both at the inside and the outside.

If you have double doors at the front door, you might also consider using entrance handle sets, which feature locking mechanisms incorporating both single- and double-cylinder deadbolts. These mechanisms will also have a latch that operate separately from the deadbolt. The latch will usually be retractable, and have a thumb piece on the lever or knob that operates it. Double doors require an operating handle set and a dummy handle set that appears just like the other one but does not actually operate anything—it only exists for symmetry and aesthetics.
