Treasure Coast Locksmith provides door reinforcement & strike plate services in Port St. Lucie, Stuart, Fort Pierce, Vero Beach, Jensen Beach, and across the Treasure Coast. Call (772) 758-1322 for mobile service. Door reinforcement is the cheapest meaningful residential security upgrade available. Upgrading the strike plate screws from 1-inch to 3-inch doubles pry attack resistance. Adding a wraparound reinforcement plate triples it.
Treasure Coast Locksmith installs for $65-$145 per lock.
Most Treasure Coast homes have a security gap that most homeowners never notice: the strike plate is held into the door jamb with 1-inch screws that barely bite the wood trim, while the jamb is hollow behind. A determined burglar with a pry bar can pull the entire strike and deadbolt assembly out of the door in under a minute, bypassing the lock completely.
The fix is simple and cheap. Replace the 1-inch screws with 3-inch framing screws that penetrate through the jamb into the king stud behind the wall. The whole wall becomes the anchor for your deadbolt instead of a few inches of wood trim.
This single upgrade typically doubles or triples the pry attack resistance of your front door for about $85 per lock.
Treasure Coast Locksmith offers door reinforcement packages ranging from basic screw upgrades to full wraparound reinforcement plates and hinge upgrades. It's one of the highest-leverage security investments available to residential owners.
What door reinforcement includes
- 3-inch strike plate screws - anchors into the framing stud, not just the jamb wood.
- Reinforced metal strike plate - thicker gauge steel, larger footprint.
- Wraparound reinforcement plate - distributes pry force across the door face.
- 3-inch hinge screws - same upgrade for the hinge side of the door.
- Latch guard installation - prevents attacks on the latch side of the door.
- Grade 1 strike compatible - works with all Grade 1 deadbolts.
- Fast 30-45 min install - entire package per lock.
- 2-3x attack resistance - measurable improvement, not marketing hype.
Why standard builder hardware fails
The gap between builder-grade strike plates and real security is larger than most homeowners realize.
Common strike plate failures
- Tradition home strike plate pulled out of the jamb with 15 seconds of pry pressure - standard 1-inch builder screws gave way.
- Jensen Beach home with an impact-rated door but standard builder strike plate - wasted protection because the strike was the weak point.
- Vero Beach homeowner discovered that the 'strike plate' was actually just a decorative metal piece behind a hollow jamb.
- Fort Pierce break-in where the deadbolt and strike came out as a single unit because neither was anchored into framing.
- Stuart home with a Grade 1 Schlage deadbolt but 1-inch factory screws - one minute of pry force defeated everything.
- Port St. Lucie homeowner thought he was secure because of the heavy deadbolt - didn't realize the weak link was the strike screws.
- Hurricane damage in Palm City where strike plate pulled loose under sustained wind pressure.
- Hutchinson Island home with corroded 3-year-old strike plate and screws falling out - full reinforcement replacement.
The physics of pry attack resistance
Pry attack resistance is the ability of a door to resist being forced open with a crowbar or similar tool. The pry attack works by applying lateral force to the edge of the door near the deadbolt, trying to bend or break the deadbolt, strike plate, or door frame until one of them gives way.
In a typical failure sequence, the weakest link is the strike plate screws. Factory 1-inch screws only penetrate into the 3/4-inch jamb wood trim. Under pry pressure, the screws pull through the wood or the wood itself splits, and the entire strike assembly comes loose.
This happens in 15-60 seconds under moderate force.
3-inch framing screws change the physics completely. They penetrate through the jamb wood and into the king stud behind the wall - typically 2x4 or 2x6 dimensional lumber that's far stronger than jamb trim. Now the pry force has to either break the steel screws themselves (very difficult) or break the framing lumber (even more difficult).
Attack resistance jumps from 15-60 seconds to 2-5 minutes, which is usually enough to send a burglar looking for an easier target.
Adding a wraparound reinforcement plate distributes the pry force across a larger area of the door face. Standard deadbolts concentrate all the force at a single point where the deadbolt penetrates the door; a wraparound plate spreads the force across a 6-inch-wide metal plate wrapped around the door edge. Combined with 3-inch strike screws, this provides 3x the attack resistance of factory hardware.

Door reinforcement tips
- Always upgrade strike plate screws to 3-inch when replacing any deadbolt. Small cost, huge security improvement.
- Wraparound reinforcement plates are especially effective on fiberglass and hollow-core doors where the door face is weak.
- Include the hinge side of the door in your reinforcement - pry attacks sometimes target the hinges.
- Check the strike plate screw length on your current doors with a screwdriver - if they're 1-inch, upgrade.
- Pair strike plate upgrades with Grade 1 deadbolts for maximum protection. Grade 3 deadbolt with reinforced strike is better than nothing but still below ideal.
- Document reinforcement upgrades in your home records - some insurance policies offer discounts for verified upgrades.

Door reinforcement FAQs
Common questions about door reinforcement and strike plate upgrades.
How much does door reinforcement cost?
Basic strike plate upgrade (new plate with 3-inch screws) runs $65 to $95 per lock. Intermediate package (strike plate plus hinge screw upgrade) runs $95 to $135. Full package (strike plate, hinges, wraparound plate) runs $145 to $245.
Can be added to any deadbolt installation for discounted bundled pricing.
How much does it actually improve security?
Measurable improvement - 2x to 3x pry attack resistance compared to factory hardware. Most pry attacks on standard hardware succeed in 15-60 seconds. With reinforced strike plates and 3-inch screws, successful pry attacks take 2-5 minutes, which is usually long enough to send burglars looking for easier targets.
Can you reinforce my existing deadbolt without replacing it?
Yes. The reinforcement work focuses on the strike plate and framing anchoring, not the deadbolt itself. You can keep your existing deadbolt and gain the security benefit.
If your deadbolt is Grade 3 we recommend upgrading to Grade 1 at the same visit for maximum improvement.
What is a wraparound reinforcement plate?
A metal plate that wraps around the door edge at the deadbolt level, distributing pry force across a wider area of the door face. Most effective on fiberglass and hollow-core doors where the door face is vulnerable to being pulled through by the deadbolt. Adds $55 to $95 over basic strike reinforcement.
Are 3-inch strike plate screws really necessary?
Yes. Factory 1-inch screws only penetrate the jamb trim, not the framing behind. Under pry pressure they pull out.
3-inch screws penetrate through the jamb and into the 2x4 or 2x6 king stud, making the whole wall the anchor. Very simple fix with significant security benefit.
How long does reinforcement installation take?
Basic strike plate upgrade with 3-inch screws: 15-25 minutes per door. Adding hinge screw upgrade: 10-15 additional minutes. Wraparound plate installation: 15-25 additional minutes.
Full reinforcement package per door: 45-75 minutes including testing and cleanup.
Can you reinforce an impact-rated hurricane door?
Yes. Impact-rated doors benefit from reinforcement just like standard doors. The pry attack resistance is separate from the impact rating.
We verify that the reinforcement hardware is compatible with the NOA-approved deadbolt so the door's hurricane rating is preserved.
Will reinforcement damage the door frame?
Minimally if done correctly. Upgrading from 1-inch to 3-inch screws uses the same holes plus one or two new pilot holes. Adding a wraparound plate requires drilling 4 small holes for mounting screws.
Both are standard installations with minimal cosmetic impact.
What's the difference between a latch guard and a wraparound plate?
A latch guard is a metal plate that wraps around the latch side of the door to protect the latch mechanism. A wraparound plate goes around the deadbolt/strike side. Both improve pry resistance on different parts of the door.
Full reinforcement usually includes both.
Can you reinforce hinges too?
Yes. Hinge reinforcement uses the same principle: replace the 1-inch factory hinge screws with 3-inch framing screws that anchor into the framing stud behind the hinge. Prevents pry attacks that target the hinge side of the door.
Adds $35 to $55 to the reinforcement package.
Are wraparound plates HOA-approved?
Most HOAs don't restrict interior-facing reinforcement hardware. The wraparound plate is mostly visible from the interior side. Some HOA requirements affect exterior-visible hardware but interior reinforcement is typically homeowner discretion.
We verify if your HOA has specific rules.
Should I reinforce all doors or just the front?
Prioritize the front door first since it's the most common attack point. After the front door, add reinforcement to the back door and side entries. Interior doors typically don't need reinforcement.
Garage entry doors are often overlooked and should be included in whole-house reinforcement packages.
