Best Mechanical Deadbolt Reviews

In this section, you’ll read about our favorite mechanical keyless deadbolts, from such industry leaders as Lockey USA, Code-A-Key, and TruePower.

Mechanical keyless deadbolts make our everyday life a little simpler and easier, by enabling us to get in and out of our homes without depending on the use of a regular key. Instead, they use a physical keypad where we can punch in our personal user code to gain entry or exit.

One of the reasons why many people prefer mechanical deadbolts is that they do not rely on electronics, which some people find to be less dependable due to reacting to weather, having glitches, or losing battery power. 

With mechanical deadbolts, its all hardware and it does its job.

Another benefit to many mechanical deadbolts is the fact that they’re often naturally bump-proof.  If you don’t know what this means, here is our article on bump proof locks to get you up to speed. 

The bottom line is that when there’s no keyhole, there’s no chance of lock-bumping and many mechanical keyless deadbolts don’t rely on keys whatsoever, so there’s that advantage as well.

That said, many people still prefer to have keyed access to their homes and many mechanical deadbolts provide that if you wish.

Some mechanical deadbolts have physical keypads on both sides of the lock, providing yet another layer of protection in case you want the option to lock the door from both sides. 

This prevents any situation where someone could break glass and reach inside to unlock your door from the inside.  With the double-sided models, that’s not going to happen.

However, with the single-sided deadbolts, you will find that there is a digital keypad on the outside where you input your code, and the inside just has a thumb-turn that you turn to lock or unlock the door that way. 

If there are no windows around your door, this would be sufficient to keep your home secure.

When made well, mechanical deadbolts overall are sturdy and no frills when it comes to ease of use. 

They are simple, durable, and look great with a number of styles and colors to choose from. Stay with us to find out more what makes these locks so special, how they differ from standard locks, and what the best models are.

Here is what we are going to cover today:

We’ll start by explaining the key differences between latches and deadbolts.

What’s the difference between a latch and a deadbolt?

The two most common types of entry door locks are single latches and deadbolt. The latch is a spring-loaded bolt which is found within the locking mechanism of the doorknob. The deadbolt, on the other hand, is located just above or below the doorknob.

Both of these locks are used for securing the door and protecting against potential intruders, but what are the differences between them? And which lock is better? Stay with us to find out!

Below is our explanation on how these locks work, how they differ, as well as what the advantages and disadvantage of each lock are.


Spring-loaded latches are the most common type of latch-base locking mechanisms. Spring latches generally fall into one of two categories – latchbolts or deadlatches.

Latchbolts – Latchbolts feature a spring-loaded bolt that is angled off at the top edge. As you close your door, the angled side of the bolt engages with the edge or the lip of the strike plate. The bolt itself retracts due to the pressure of contact with the strike plate.

When the bolt passes a certain point, it extends and locks into the strike plate due to the pressure being released from the spring, securing the door and keeping it closed. Latches are designed to retract and disengage when you turn the door handle to open the door.

Deadlatches– Deadlatches feature what is known as a guardbolt – a small cylindrical bolt that is positioned just beside the latchbolt. The guardbolt is designed to move together with the latchbolt up until the point when the latchbolt extends into the strike plate.

The guardbolt then remains in depressed position against the strike plate, preventing the potential intruders from “jimmying” or “shimming” the latchbolt. The positioning of the guardbolt doesn’t allow the latchbolt to be depressed by using a credit card or some other thin, flat tool.


Deadbolts are generally thicker and heavier than spring latches, and they are not angled or rounded at the end.

Deadbolts are usually made of steel, bronze or brass, and they extend deeper into the door frame than spring latches. A deadbolt can be engaged by using a key or turning a knob. Most expensive models can also be engaged by using an automated motor.

Deadbolts engage when the tumbler inside of the lock rotates to the specific position and the pins move into alignment,

One of the most noticeable differences between deadbolts and latches is that latch-based locks have doorknobs or door handles, while deadbolt locks don’t.

Next, let’s talk about money!

Are deadbolts expensive?

Many people decide not to install deadbolts because they tend to cost more than standard locks. However, any locksmith will tell you that deadbolts are actually relatively cheap considering the level of protection they provide for your home.

Depending on the model and class you want to buy, a deadbolt and installation will generally cost you anything from $100 to $250. The majority of homeowners who had installed deadbolts to their homes, though, reported paying less than $200 per lock.

David Helms, the owner of the highly-popular E&S Security and Locksmith from Carlotte, N.C., says that the installation of the deadbolt depends on several factors.

He explains that it costs $50 to 60$ for the trip, $40 to $50 for the deadbolt and $45 to drill and install the deadbolt on a wood door, or $50 to install it on a metal door. This means that a typical job costs $140 to $160.

Most costumers decide to buy deadbolts at large home improvement stores because they generally cost 50 dollars less than what hardware stores sell them for.

Most locksmiths charge $140 to $160 for the deadbolt, which includes the lock and the installation.

Although deadbolts are more expensive than the standard bolts, it is worth saying that you might be able to recoup some of the installation costs through your insurance payments. Many insurance agencies nowadays offer discounts for having deadbolts installed in your home.

Moving onto Code-A-Key all-weather double keypad lock…

Code-A-Key All-Weather Double Keypad Lock

all weather mechanical lockThis is a double keypad mechanical deadbolt that has an average of 4 stars on as it stands, with over 20 buyer reviews.  The unit operates by punching the right access code onto the keypad on both sides: outside and inside. So in order to grant entry or exit you’ll have to know the correct code. 

On the upside, this is a great double-sided lock that can work wonders for home security in the event that you have a window near your door. 

This way, break-ins can be prevented because robbers can’t reach through a broken window to unlock your door from the inside (hence bypassing the deadbolt). 

On the slight downside, you need to consider that with a deadbolt like this, in the event of an emergency, you lose precious seconds evacuating a location because you need to punch in the code.  Just something to consider for safety’s sake.

The two keypads work independently of one another, meaning you’ll have to set your code for each separately.  There is a “Quickcode” feature for quick changing of your codes as well.

This is a truly keyless lock, meaning no back-up keyhole like others, and it is also bump proof in that regard as well – a big plus!

This Code-A-Key All Weather lock is suitable for window pane doors, wrought iron gates, as well as front doors that need 2 way entry control.

Technical Specs

  • Dual Keypads for 2-way Security – Reliable All-Weather Mechanical Operation – No Batteries Needed
  • Eliminates “Reach Through” Security Risk in Window Doors & Gates – “Bump Key” Proof
  • Independant Keypad Programming – Set Operating Mode & Unlock Code Separately on Each Keypad
  • New “QuickCode” Design for Fast and Easy Code Changes

TruePower Anaconda All-Weather Deadbolt

anaconda deadbolt

This Anaconda mechanical lock from TruePower matches both right hand and left hand door types.

It is a deadbolt that offers 2 types of entry methods: by entering your private combination code onto the 13-digit alphanumeric keypad, or by using a physical key.

Your access code can include up to 10 digits for maximum security. Moreover, for additional safety, there are 2 standard keys that can always help in case you forget your code, or if you feel nostalgic for your regular keys, although you don’t really need them unless its “just in case”.

However, it should be noted here that the code is not sequential, which means you won’t have to punch the code in a specific order in order to gain access to your home or establishment. 

As we said previously, this non-sequential entry of your code could be seen as a security drawback, although, no one has ever reported a break-in for this particular reason, and, if anything, its actually more convenient for the homeowner than it is an advantage for a thief, would would take them a a good month to stand there punching away in order to find the 10-digit code you’ve come up with. 

It should be noted also that this is a single combo lock, where as some other locks let you program multiple combos.  For those looking for a multi-combo lock, this is not the one, but it does make everything simpler.

Technical Specs

  • All-weather operation – No batteries required – Easy to open door handle design
  • Replaces existing deadbolt on doors up to 1-7/8″ thick – Fits standard 2-1/8″ diameter cutout
  • Unlocks by push-button code or with standard keys (2 keys included)
  • User programmable code up to 10 digits / 13-digit alphanumeric keypad + CLEAR key
