All Your Deadbolt Lock Questions Answered!

What To Look For When Choosing A High-Security Deadbolt Lock:

Because deadbolts have so many smart features to choose from, every model has a special set of characteristics, some of which will be relevant to home security, some to office spaces and some to institutions like universities or government premises.

If we break down what is essential for each space, it becomes easy to see the right direction in which to proceed.

Smart Home Devices

One of the most dreaded mistakes homeowners can make is losing their keys. The beauty of keyless entry locks deadbolts is that they eliminate this danger by offering pin code functions.

Choosing a deadbolt with a keypad greatly reduce the risk of being locked out of your house, and minimized the chance of intruder’s lock picking or “bumping” your lock(s) with a blank key and gaining access to your home.

If you are a forgetful person, this is a great feature to have.

Unlike the Kwikset Smartkey models that have to be rekeyed every time a new tenant moves onto the property, landlords can simply delete the previous access codes and create new ones, saving time, energy and money.

Another characteristic to look out for when choosing a deadbolt for home use is its ability to be controlled and monitored by a smartphone.

If you are sitting at work pondering whether or not you remembered to lock your door this morning, Z-wave devices let you check your deadbolt’s locked status, and lock it remotely from your smartphone should it not be locked for whatever reason.

Office Space Security

Offices and workspaces often require a number of employees to enter and exit accessways at least twice a day.

Providing each employee with their own key can cause major headaches when keys get lost or when employees leave the company.

Fortunately, smart locks such as the Schlage Connect Touchscreen BE469NX give employers the option of designating a unique code for each employee to use when entering.

This feature is invaluable for employers that want to keep track of their employees’ comings and goings, time of arrival and clock-out, absenteeism and more.

The ability to activate “privacy mode” and disable all pin codes except for the master code is very useful to safely secure the workspace after all employees have left for the night, preventing them from access after-hours.

Best Deadbolt Locks For Institutions

Thousand of students filter through the hallowed halls of tertiary education buildings every single day, each requiring access to a specific selection of computer rooms and lecture halls.

To prevent civilians sauntering in willy-nilly to make free use of the expensive and exclusive facilities, heads of campus security are fervently advised to install the best deadbolt locks possible.

Make sure that whatever brand and model you choose, it has exceptional battery life.

The Schlage Camelot Touchscreen deadlock has a feature that triggers an alarm should it detect any tampering or forced entry and uses Z-wave technology to communicate through the institution’s wife connection.

Are Deadbolt Locks Secure? How Do Improve The Security Of My Deadbolt Lock?

Deadbolts like the Schlage Z-Wave Connect Camelot Touchscreen Deadbolt are impeccably secure for protecting the home against intruders because of their exceptionally integrated technology and versatility.

This kind of smart lock is most secure when combined with traditional locks and extra door frame support. Ways to optimize your door security are as follows:

1. Install your deadbolt securely with 3-inch screws (minimum) to securely fix the strike to the doorframe to prevent someone from kicking it in. The deeper the screws go into the doorframe, the less likely the door is to be broken down.

2. Consider replacing any hollow or glass doors with solid wood or metal-plated wood. Even the best deadbolt locks are no match for intruders who use brute force on the wood of the door itself to gain access to your space.

3. Do not use a single cylinder deadbolt on door fixtures that are close to a window. Intruders could smash the window and unlock the deadbolt easily from the inside. Rather choose a double-cylinder deadbolt which requires a key to open both the door inside and outside.

4. Learn the ins and outs of your smart deadbolt software to optimize its usefulness. Investigate what features it offers and integrate your security needs with it. Spending money on a high-security smart lock is totally justified, but only if it is performing to its full potential.

5. A door jammer is a great way to add another level of security to your house or office. They are portable, strong to boot and can be brought with you on getaways to improve security in hotels, lodges, and the like.

Which Is Better, Single Or Double-Cylinder Deadbolt Locks?

The essential difference between single and double-cylinder deadbolts is that the former only accepts a key from the outside of the door, whilst the latter can be unlocked from within as well as from the outside.

As discussed above, any door close to a window should be fixed with a double-cylinder lock, so thieves cannot smash the window and turn the unlocked knob from the inside.

Although a double-cylinder lock is safer at face value, it also has its pitfalls. An emergency evacuation of the house can be slowed down if residents have to fumble for keys, while a single cylinder deadbolt only requires one swift turn of the knob.

It is a personal choice that must be thought through carefully with special attention given to the setup of the house.

Should I Buy An Electric Deadbolt Lock?

There are pros and cons to choosing an electric deadbolt. Keyless entry locks are almost always battery powered, usually fitted with AA or AAA batteries, although deadbolts that run off the house’s power supply are also available.

The obvious question is this: what happens to my electric deadbolt if the power cuts out?

If you are living in an area that hardly ever experiences electrical problems, it is perfectly safe and relatively convenient to use.

If the power should cut, the smart deadbolt will either switch to fail-safe mode, unlocking the mechanism, or fail-secure mode which locks the entryway shut until the power returns.

If your city has regular power-cuts, consider buying an analog deadbolt, or a battery-powered smart lock that doesn’t rely on grounded electricity.

Can Someone Pick A Deadbolt Lock?

All commercial locks must be scrutinized and tested heavily to gauge the effectiveness of their security measures.

Locks are evaluated by the American National Standards Institute or ANSI and are given a grade based on their resilience to tampering.

The general rule is that the higher the price on a security tool, the better quality it is and thus, the higher the level of protection it will provide.

We recommend going no lower than a Grade 1 on the ANSI scale.

The sad thing about the globalization brought about online is that it has become very easy to share illicit information.

Getting one’s hands on a lock picking kit can be surprisingly simple, and there are resources all over the internet explaining how to use it.

What is ground-breaking about deadbolts, is that unlike traditional locks, they are not spring-loaded, so cannot be picked in the traditional way.

There must be a key inserted into the cylinder for the bar to be released from the door jamb and allow access.

Deadbolts of lower quality are at risk of being picked using something a rudimentary as a bobby pin and some know-how, so always go for one of the best deadbolt locks on the market like the Schlage Camelot Touchscreen or the Yale Assure Keyless Touchscreen Deadbolt.

Although these deadbolts can be picked, they will take extremely long to do so, deterring intruders and placing them at high risk of exposure.

Luckily, both of these deadbolts are Z-wave devices and will alert you on your phone if a break-in is being attempted.

Schlage is back at it again with another deadbolt for the books. With an ANSI rating of Grade 2, it falls short of the accolades of its more technologically advanced successor, the Schlage Z-Wave Connect Camelot, but still has much to offer.

It has a non-touchscreen keypad, its buttons backlit and coated with a layer of silicon wear-and-tear protection for optimal resilience.

It also gives users the choice between using a key or entering a PIN code.

Aesthetically speaking, this deadbolt has a vintage feel and would be a great addition to the overall look of your door, if your decorative style is more traditional than modern.

The Antique Brass finish gives the metal an almost regal feel, making this affordable single-cylinder specimen look more expensive than it really is!
