Deadbolt locks of vertical design are renowned for their reliability and unparalleled defense against illegitimate intrusions. Their unique formation, paired with a sturdy strike plate situated on the door frame, provides a significant barrier to potential forced entries. This layout greatly compounds the obstacles an aspiring burglar could encounter when trying to remove the door from its frame or initiate an unapproved entry.

Most smart locks available today, are designed for single-cylinder deadbolts. So if you’re renting an apartment with a Jimmy-proof door lock, your options are limited as you can’t start drilling holes in the door!

In this article, I discuss two ways you can cleanly retrofit your vertical deadbolt with a smart actuator, to give your door the smarts it needs.

I’ll also discuss some smart vertical deadbolt locks that you can use if you are replacing your existing lock and installing a new one.

Updated May 2023 to remove the Samsung SHS-D500 which seems to be discontinued.

A quick summary of your options here which I discuss in detail below. You can use an August Smart Lock with specialized adapter from Etsy or for a cheaper option, you can try the SwitchBot Lock which fits over the thumb turn. Both of these solutions are “smart” in the sense that they can be voice controlled and connected to home automation systems.

Best Jimmy-Proof Deadbolt Replacement Options

As I discussed below, I ruled out a lot of models for new installations as I wasn't convinced they were secure enough. That left the Gateman by Assa Abloy and the Samsung SHS-D500 model (which since I published this article is now out of stock so I removed from this list).

While these devices have some nice tech like biometrics and RFID, neither are “smart” in that they cannot be voice controlled by Alexa, Google Home, or Siri; nor can they be connected to smart home hubs. They are both standalone solutions, which is a pity.

Things to look out for when making a decision


When considering smart lock compatibility, look for products that integrate with existing setups, such as the August Wi-Fi Smart Lock (4th Generation) and the SwitchBot Wi-Fi Smart Lock. These locks are compatible with popular smart home hubs, enabling control via voice commands or apps.


Ease of installation and setup is vital for a Jimmy-proof vertical deadbolt smart lock. Both the August Wi-Fi Smart Lock (with the SturdyLock adapter) and the SwitchBot Wi-Fi Smart Lock offer straightforward installation and setup processes, fitting on existing deadbolts and requiring minimal hardware.

The Gateman option require more invasive installation which will take longer.


Security features and encryption are essential for smart locks. The August Wi-Fi Smart Lock utilizes biometric verification, door sense technology, and a keyhole-free design. 

It's crucial to choose locks with robust security mechanisms and encryption protocols to protect against unauthorized access and potential hackers.

Control Methods

Remote access and control capabilities are significant aspects of smart locks, allowing you to lock and unlock doors from anywhere using a smart device or voice control. The August Wi-Fi Smart Lock and SwitchBot Wi-Fi Smart Lock provide push notifications, access management, and voice control through popular assistants.

Power / Batteries

Lastly, consider battery life and power backup options when choosing a smart lock. The August Wi-Fi Smart Lock operates on batteries and should be replaced periodically. Some locks, like the Gateman G-Swipe, offer low-battery alarms and emergency power options to ensure continuous functionality.


What is a Jimmy Proof Deadbolt Lock?

A Jimmy Proof Deadbolt Lock is a unique type of lock designed to provide enhanced security for doors. 

It features a surface-mounted vertical bolt that slides into a sturdy strike plate, making it resistant to forced entry techniques like lock picking, prying, and “jimmying” with a crowbar or other tools.

Why is it called a Jimmy Proof lock?

The term “Jimmy Proof” originates from its ability to withstand attempts at “jimmying” the lock. 

In the world of locks and security, “jimmying” refers to the act of breaking or bypassing a lock using force or tools. 

This lock's name highlights its effectiveness in preventing such attempts.

How does a jimmy proof deadbolt work?

A Jimmy Proof Deadbolt works by having a vertical bolt that securely fastens into the strike plate mounted on the door frame. 

When the key is turned, the bolt slides up into the strike plate, providing a strong and secure connection. 

This vertical bolt design makes it difficult for intruders to pry the door open or force their way in, ensuring your home stays secure.

How I Tested

For this article on Jimmy Proof Vertical Deadbolt Smart Locks, I conducted extensive research on various smart locks for doors and ways to smarten up these types of locks. This research included reading various threads on Reddit, watching a number of relevant Youtube videos, and checking out the specifications and reviews of the main devices for sale for both retrofit and new installations.

I take my recommendations seriously and ruled out a number of Jimmy-proof smart locks from brands like Sonew, Xbroom, Dioche, and CfoPiryx where I wasn’t convinced they would be suitable for improving one's home security.
