Home Security Door Checklist

How to use this checklist

Pick a dry, bright part of the day and walk the outside of your home with a notepad or your phone. Start at the front door and move clockwise, stopping at every door that leads in: the front entry, the back door, side doors, the garage entry door, sliding glass doors, French doors, balcony doors and the door from an attached shed or workshop if there is one. Treat each as a separate item, because each is a separate way in.

For each door, look at the same short list of parts: the door itself, the frame, the hinges, the lock set, the strike plate, any glass nearby, and the lighting and visibility around it. You are not hunting for dramatic faults. You are looking for the small things that quietly weaken a door: a loose screw, a worn strike, a gap, a corroded latch, a window you can reach through.

Do not take apart anything that is under tension or that you are unsure about. This guide is about inspection and simple tightening, not about disassembling locks. When something needs more than a screwdriver, note it down and ask a technician. Our security assessment service covers the same ground with a trained eye.

The door itself

Start with what the door is made of and how it behaves. Solid wood, solid-core, fibreglass and steel doors all resist force reasonably well when properly installed. Hollow-core interior-style doors on an exterior opening are a weakness, as are doors with large decorative panels that have cracked or delaminated. Look for splits near the lock, soft spots, water damage at the bottom edge and swelling that stops the door from closing flush.

Florida's humidity means wooden doors move with the seasons. A door that sticks in summer and rattles in winter may not be latching properly during part of the year. Close the door gently and watch the latch: it should catch cleanly without lifting, pushing or slamming. A door that needs a shoulder to close is a door that may not be fully locked when you think it is.

Check the edge of the door around the lock for cracks or earlier repair. A door that was kicked in once and patched can be much weaker than it looks. If you see fresh splintering or tool marks, treat it as a sign of attempted forced entry and read our page on signs of lock tampering.

• Solid or solid-core construction on every exterior door
• No splits, soft spots or swelling near the lock
• Door closes flush with a clean latch, no slamming needed
• No old kick damage or patched repairs around the lock
• Weatherstripping intact so the latch is not pushed out of line

Deadbolts and lock sets

Every exterior door should have a deadbolt as well as a handle latch. The handle latch alone is designed to keep the door closed, not to resist force. A deadbolt that throws a solid bolt into the frame is what gives the door real strength. Check that the bolt extends fully when locked and that it moves smoothly without sticking, grinding or needing to lift the door.

Check the lock is firmly attached to the door. A loose or wobbling lock set is easier to attack and often a sign that the screws or the internal parts are worn. Wiggle the handle and the deadbolt thumb-turn. If either moves in a way that is more than a hair, tighten the visible screws gently and ask a technician to look if it persists. Our page on a loose or wobbly door lock explains the usual causes.

Look at the cylinder. In coastal areas such as Boca Raton, Deerfield Beach and Pompano Beach, salt air corrodes brass and steel over time. A cylinder that is pitted, stiff or discolored may be on its way out. See our salt air lock care guide. If you are unsure which deadbolt is right, read how to choose a deadbolt.

Strike plates and the frame

The strike plate is the metal plate in the door frame where the latch and the deadbolt land. It is the most overlooked part of door security. A standard strike is often held by two short screws that go only into the thin door jamb. A hard kick can split the jamb and pop the plate out, even if the lock itself is perfect.

Look at the screws. If they are short and the plate is thin, a technician can replace them with longer screws that reach the structural framing behind the jamb and a reinforced plate. Our page on strike plate reinforcement explains the upgrade. It is one of the most cost-effective improvements for the effort involved.

Check the frame itself for cracks, rot and gaps. Termites and moisture can weaken wooden jambs, and a frame that looks sound from outside may be soft underneath. Press gently along the jamb near the strike. If it gives, the door is not as strong as it looks. For more on this, read our guide to door frame security.

Hinges

Hinges are a second weak point. On a door that opens outward, the hinge pins are exposed on the outside, and an attacker can remove them if they are not secured. Look at whether the pins can be lifted out. If your door swings out, ask a technician about security hinges or non-removable pins.

On an inward-opening door, the hinges are protected, but their screws still matter. Check that every hinge screw is tight and that the screws reach into the framing. Short screws in a weak jamb are the hinge-side version of the short strike screws. Replace stripped screws with longer ones where the wood allows.

Open and close the door slowly and watch the gap along the hinge side. If the door sags, scrapes the frame or leaves an uneven gap, the hinges may be loose or worn. A sagging door can also misalign the latch and deadbolt, which makes them harder to lock and easier to defeat.

Glass near the door

Glass beside or in the door is a common weakness. A sidelight, a decorative panel or a window within easy reach of the lock can let someone break the glass and reach in to turn the thumb-turn. Stand outside and measure with your arm. If you can reach the inside lock through any glass, a determined person can too.

The solution is usually not to remove the glass but to change how the lock works. A double-cylinder deadbolt that needs a key on both sides is a common answer, but it creates a fire-safety risk because you need the key to leave. Many jurisdictions restrict or discourage them, and our page on fire safety and door locks explains the trade-off. Safer alternatives include security film on the glass, a decorative grille, or moving the lock out of reach.

If you have impact-rated doors or windows, as many coastal Florida homes do, check that the hardware matches the rating. See our page on impact door hardware. A strong door with a weak lock set undoes the point of the strong door.

Sliding glass doors and French doors

Sliders are among the most common entry points in Florida homes, and the factory lock is often a simple hook latch. Check that the door slides smoothly and locks fully. Make sure the door cannot be lifted out of its track from outside. A secondary bar or pin in the track is a simple and useful addition. Our page on sliding glass door locks covers options.

French doors have two leaves, and the inactive leaf is held by flush bolts at the top and bottom. Check that the bolts extend fully and seat into solid holes. Loose or stripped bolts are a weak point. Also check the gap between the two doors, because a wide gap allows tools to reach the latch.

For both types, inspect the glass for cracks and check that the weatherstripping is intact. Worn seals let humidity in and can also let a tool slide in. Balcony doors on upper floors still count: a door that is hard to reach is not a door that is impossible to reach.

Garage entry doors and the garage itself

The door between your garage and your living space is an interior door that often gets treated like one. It should have the same deadbolt and strike quality as an exterior door, because a person who is inside your garage is already out of sight of the street. Check that it closes and latches reliably, that it is solid, and that you actually lock it.

Think about how the garage itself is secured. An automatic opener with a remote left in a parked car is an easy way in. Do not leave a remote or an access card in a car outside. Our page on garage entry door locks explains what a technician can fit.

Also check the side door of a detached garage or shed. Cheap hasps and padlocks are quick to defeat, and tools stored inside can help someone get into the house. Treat any outbuilding that holds ladders, cutters or tools as part of your security plan.

Putting your notes in priority order

Once you have walked the whole house, sort what you found. A simple three-column list is enough: fix now, fix soon, ask a professional. Things that leave a door unable to lock, such as a deadbolt that does not reach the strike or a latch that does not catch, belong in the first column. A door that cannot lock is not a door, and those items should not wait for a convenient weekend.

In the second column go the improvements that make a good door better: longer strike screws, a reinforced strike plate, a secondary pin in a slider track, a better light, a trimmed hedge. These are modest jobs that add real resistance. In the third column go anything involving a lock you do not want to take apart, frames that feel soft, glass within reach of a thumb-turn, or hardware you suspect is worn out.

A table can help you compare doors at a glance when you come to talk to a technician.

• Photograph each problem so you can describe it on the phone
• Note the make of any lock you can read on the face or edge
• Mark anything that has failed to lock even once

Lighting, visibility and habits

Good lighting is part of door security. Check that every entry has a light that works, that it is positioned so it lights the door and not just the ceiling, and that bulbs are replaced promptly. Motion-activated lights near side and rear doors are useful because they signal that someone is there. Trim shrubs that hide doors from the street, since concealment helps anyone trying to work unseen.

Habits matter as much as hardware. Lock the door every time, including when you are home and when you are only stepping out briefly. Do not hide a spare key outside, for the reasons explained in why hiding a spare key fails. Keep a record of who has keys, and change the lock when that list becomes uncertain.

Finally, write down what you found. Group the notes into fix now, fix soon and ask a professional. Then call and talk it through. A technician can describe the options for each door, explain how a quote works on the phone, and tell you when an on-site visit is needed. That plan, built door by door, is the real checklist.

Turning a walk-through into a short work order

Once you have walked every entry point, the notes in your hand are only useful if they can be handed to someone else. Rewrite them as a short list, one line per door, naming the door by where it sits, such as front entry, kitchen side door, or back slider. Under each line, write what you saw in plain words: bolt does not fully extend, frame is soft near the latch, handle sags when pushed. Skip guesses about causes. A technician would rather see the symptom and decide on the cause once the hardware is in front of them.

Take a few photos before the call, and keep them wide enough to show the whole door and close enough to show the hardware. A photo of the edge of the door with the bolt extended tells more than a paragraph of description. Note the approximate age of the home and whether any locks have been replaced since you moved in, because mixed brands on one property change how keying and parts are handled. If a door is shared with a neighbor, an association, or a landlord, write that down too, since permission may be needed before anything is changed.

When you call, read the list in the order of your own worry, then listen to how the work is proposed. The scope and any quote are explained before work begins, so use that moment to ask which items are repairs, which are upgrades, and which could wait. It is perfectly reasonable to do the weakest door first and schedule the rest later. Keep the list afterward and tick items off with dates, so the next review in a year starts from facts instead of memory. Take your time with this part, because a few minutes of attention now usually prevents a second visit later.
