Our Door Locking Mechanism Buying Guide

Homeowners have more options than ever when it comes to locks. You can choose digital locks that let you leave home without a key and deadbolts that can withstand up to 800 pounds of force. There are also sliding door locks you can install on outbuildings or interior rooms and plates that will keep your existing deadbolt in place, preventing children from unlocking doors while you aren’t looking.

The first question to consider is whether or not you need another door-locking mechanism — and if so, where? Even if your hometown is the very picture of small-town America, a lock can give you peace of mind. And if you own a home in a higher-trafficked area, such as a big city or even a suburb close to one, your safety might be a real concern that can be alleviated by a simple purchase.

You then need to decide where a better lock would come in handy and what your needs are (for example, which way does your door swing? Does the existing hardware present any problems for switching locks out?). You’ll also have to think about what kind of functions and footprint you want your locking mechanism to have and whether you need the lock to use the same key as other locks in your home. You may also want to consider what kind of style and finish you want.

If you rent, things can be a little more complicated. Your landlord should have installed at least a standard deadbolt before you moved in, but those deadbolts might leave something to be desired. Before you pull out the screwdriver or drill, check your lease. You may be prohibited from doing any work on your rental that can leave a mark, including installing locks. Whether your rental agreement permits it or not, though, running this project by your landlord is always a good idea — especially if it’s something that you’ll leave behind when you move out.

The most common type of exterior deadbolt has a single cylinder. This type only locks on one side, so when you aren’t home, you won’t have your deadbolt in place. Single-cylinder locks are often installed on apartment doors to provide the minimum extra security necessary to residents. They can work fine if you just want a little extra protection.

A double-cylinder deadbolt lock, however, gives you an extra layer of security by providing a lock outside as well as the inside. Simply insert the key and your home will be secured even when no one’s on the other side of the door to activate the lock. The downside of a double-cylinder lock, which requires the use of a key on both sides, is that it makes it harder to leave the home in a hurry or when you’re somehow incapacitated. In fact, you may have to check the legality of double-cylinder locks in your local area, as they may be prohibited by certain fire codes.

DWYM Fun Fact

Locks have been in use for at least 4,000 years, with the first known lock dating back to ancient Egypt. The wooden bolt-style lock was a precursor to what is known today as a pin tumbler lock, which uses various types of pins to ensure it doesn’t open without the right key.

It wasn’t until 1778 that locksmiths made a real effort to improve the lock’s security. That was the year Robert Barron patented the first double-acting tumbler lock. He was followed by Joseph Bramah, who patented a lock in 1784 that was considered (at the time) to be revolutionarily tamperproof.

Perhaps the most famous lock inventor today was Linus Yale, Jr., whose last name you may know from the Yale family of locks still in use today. Yale Sr. invented a pin-tumbler lock in 1848, while his son patented a cylinder pin-tumbler lock in 1861. A year later, he invented the combination lock still in use today.

The Door Locking Mechanism Tips and Advice

  • Locks are rated according to standards set by Builders Hardware Manufacturers Association. The top rating is BHMA A, with B being second and C being third. Locks are rated separately for security, durability and finish, with the certification affixed to the packaging of each lock using a label.
  • Shop for sturdy locks designed to withstand tampering of the hardware (via tools) as well as brute force.
  • Consider whether you need something tamperproof on the inside of the door. For example, do you need your lock to be childproof? If so, you could install a plate to lock your deadbolt into place. You could also place it higher so only adults can reach it.
  • If you already have a deadbolt, look at how it’s installed to determine whether or not it easy it might be to replace. You may want to choose a similar locking mechanism to ensure a proper fit.
  • The finish of the lock helps it look nice, but also impacts its durability. Brushed nickel over a stainless-steel base can ensure your lock gives you years of reliable use. It’s especially important to look for a rust-resistant option for outside door locks since they’ll be exposed to moisture year-round.
  • A keyless lock can be convenient since it eliminates the need to dig your keys out every time you return home. You will also be able to issue codes to visitors like service providers or family members. You can easily change the codes if you ever want to restrict access to someone who had it before.
