Beyond the Deadbolt: A Homeowner’s Guide to Door Reinforcement


Published Date: Oct 1, 2025

A strong lock is a great start, but true home security involves more than just the deadbolt. The door, frame, and hinges all play a part in keeping your home safe from forced entry. Effective door reinforcement strengthens these key areas, creating a much stronger barrier. If you’re wondering how to reinforce a door, thinking about the entire entryway as a system is the best approach. This guide from Sure Lock & Key will walk you through practical steps to make your door significantly more secure.

Start with a Solid Core Door and Door Armor


Start with a Solid Core Door and Door Armor
The type of door you have makes a big difference. Many homes have hollow-core doors, which are not very strong. Upgrading to a solid core door is one of the most effective changes you can make, as these doors are dense and much harder to break through. For an existing door, you can add door armor. This hardware includes steel plates that fortify the areas around your locks and hinges. A quality solid core door combined with door armor makes it much more difficult for someone to kick in or pry the door open.

How to Reinforce a Door Frame and Jamb


How to Reinforce a Door Frame and Jamb
A strong door is only as good as the frame holding it. During a forced entry, the door frame is often the first thing to break. To reinforce the door frame, focus on the jamb where the lock’s bolt enters. Installing a door jamb reinforcement strip — usually a long piece of steel — strengthens this vulnerable spot and helps distribute force more evenly. For even greater protection, reinforce the hinge side as well and consider upgrading the strike plate to a security strike plate designed for high-impact resistance. This type of hardware works with the jamb reinforcement strip to create a stronger, more secure lock area.

Upgrading Hardware: Security Hinges and Strike Plates


 Security Hinges and Strike Plates
Your door’s hardware is another critical component of its overall strength. Here is how to reinforce a door with a few key upgrades:

  • Install a security strike plate: Replace the standard plate with a security strike plate. These are made of heavy-duty metal and use long screws that anchor deep into the wall stud, providing a much stronger hold.
  • Add a heavy-duty deadbolt: Pair your reinforced strike plate with a heavy-duty deadbolt. A quality deadbolt is more resistant to being battered or pried open.
  • Upgrade to security hinges: Replace standard hinges with security hinges. These have features like non-removable pins that prevent the door from being lifted off its frame.
These upgrades are covered in more detail in our article on strategies for upgrading security doors.

For an all-in-one solution, consider a door reinforcement kit. These packages contain essential components — like jamb shields, hinge shields, and lock protectors — all designed to work together. Instead of buying each piece separately, a kit provides a complete system engineered to fortify every weak point. This is often the most cost-effective and straightforward approach for a major security upgrade. The main benefit is that all parts are matched for strength, creating a cohesive barrier that distributes the force of an impact across the entire door structure. It’s a convenient and highly effective way to ensure comprehensive door reinforcement without the guesswork, giving you professional-level security in one package.

What is a deadbolt

Today many people use deadbolt locks for their front doors. You might be curious why these locks are that popular. They are one of the best ways to enhance your home security. Deadbolts are really hard to pick and almost impossible to open with the help of a credit card or knife. These locks are made of solid materials, so they are resistant to various attacks. There are two types of deadbolt locks – single-cylinder and double-cylinder ones. The first type is quite common. It has a keyhole on the outside and a thumb turn on the inside. It’s extremely convenient, as, in case of an emergency, you won’t have to search for a key. The double-cylinder one requires a key on both sides. It is considered to be the most secure option. Sure Lock & Key knows everything about deadbolts and we want to share our knowledge with you.
