How to think about ranking doors
Ranking entry points is not about predicting what any one person will do. It is about asking two plain questions of each door: how easy is it to approach without being seen, and how much does the door and its hardware resist being forced or manipulated? A door that is hidden from the street and has light hardware sits near the top of the list. A door in full view of neighbors with solid hardware sits lower.
Many owners are surprised by their own ranking. The front door is where visitors arrive, so it gets a good lock and a light. The back of the house, where nobody sees, may have a hollow door with a knob lock that came with the house. Homes in Miami-Dade vary widely, from concrete block houses in Hialeah and Kendall to older Mediterranean homes in Coral Gables, townhouses, condos and waterfront properties. The right ranking depends on yours.
Use this page alongside the broader layers planning guide. The layers guide explains the big picture, and this page focuses on one layer in detail: the doors themselves.
The front door: visible, but not always strong
The front door benefits from visibility. It faces the street, it usually has a light nearby and neighbors tend to notice who comes and goes. That visibility is a real security layer. The weakness is that front doors are often chosen for appearance. Decorative glass, wide sidelights and ornate hardware can be handsome and still provide a modest level of resistance.
Check the door slab first. A solid-core wood, fiberglass or steel door resists force better than a hollow one. Then check the frame: look for cracks near the strike plate, gaps between the door and the jamb, and screws that have loosened. In South Florida, humidity and termites can quietly soften door frames, so press gently around the lock area and look for signs of rot or damage.
Then look at the hardware. A deadbolt with a solid throw, a reinforced strike plate and a lock that turns smoothly is a good base. If you own an older house and are not sure how many people have keys, rekeying is often the most useful step. See rekeying after moving in for what that involves.
Sliding glass and patio doors
Sliding glass doors are common in Miami-Dade, in houses, townhouses and condos. They open onto patios, pools and balconies, and they are often out of sight from the street. The factory latch on many sliders is light, and on older units the door can be lifted or shaken in its track in ways that defeat the latch even when it is engaged.
A good review looks at three things: the latch itself, the track and rollers, and the glass. A worn latch may not fully catch. A bent or dirty track lets the door rattle. Loose rollers let it ride up. A secondary lock, a security bar in the track or a pin through the frame adds resistance, and a technician can recommend what suits your model without changing how the door looks. Our page on sliding glass door locks goes into more detail, and patio door security upgrades covers the options.
Do not rely on a broom handle or a stick in the track as a permanent answer. It helps, but it is easily forgotten, and it does nothing if someone lifts or forces the door at the latch side. If your slider has been difficult to lock for months, that is itself a warning sign to have it looked at.
The garage entry door
The door between the garage and the house is the most neglected entry in many homes. It is often a hollow interior-grade door with a simple knob lock, on the assumption that the garage door is closed and the garage is secure. But garage doors are opened by remotes left in cars, forgotten in the open position or defeated by other means, and once a person is inside the garage they are out of view with plenty of time.
Treat the garage entry as an exterior door. It should have a solid slab, a deadbolt, a reinforced strike plate and a frame that can take force. Keep it locked even when you are at home, including when you are working in the garage. The same applies to the garage remote: do not leave one in a parked car, and do not leave the garage door open while you are away from it.
Our page on garage entry door locks explains what a technician typically checks. If your garage is attached and the entry door has been unchanged since the house was built, it is a good candidate for an upgrade.
Side doors, rear doors and service doors
Side and rear doors are quiet entries. They are used less, lit less and seen less, which is exactly why they rank high. Many homes have a laundry room door, a kitchen door to the yard or a side door near the driveway. These are often fitted with whatever basic lock was on hand at the time the house was built, and they may have been repainted so many times that the latch no longer lines up well with the strike.
The checklist is similar to the front door but with a stronger focus on frames and lighting. Is the door frame solid and the strike plate anchored with long screws? Is there light on that side of the house? Can a person approach the door without passing a window that looks out on a neighbor? If the door has glass in it, is the lock out of reach from the glass?
Gates should be included in this category. A side yard gate that does not latch properly, or that has a latch on the outside that anyone can lift, is the first barrier to the side and rear doors. See residential gate locks for how latches and locks are matched to gates.
Doors with glass in or beside them
Any door with a glass panel, sidelight or transom near the lock raises a specific question: can a person break the glass and reach the thumbturn or handle on the inside? This is common on French doors, on older entries with decorative panels and on many patio doors. It is not a reason to rip out beautiful doors, but it is a reason to think about what is within arm's reach.
Options include a double-cylinder deadbolt that requires a key on both sides, impact-rated or laminated glass, security film on the glass, or moving the lock further from the glass. Double-cylinder locks carry a safety tradeoff: in a fire or other emergency, a key must be found to leave. That is why you should read our comparison of deadbolt types before choosing one, and why some jurisdictions and buildings restrict them.
A technician can look at your specific door and tell you which approach fits. We do not describe how to defeat locks or glass, and nothing here is meant to instruct anyone in doing so. The goal is to help you decide what to ask for.
Balcony, upper-floor and condo doors
In a condo or apartment building, the unit door is your main entry, and the building handles the rest. The corridor, lobby, stairwells and exterior are outside your control. For the unit door, the useful checks are the deadbolt, the strike plate, the door closer and the peephole or viewer. A door that does not fully close on its own may not latch, and a latch that is not engaged does nothing.
Balcony doors matter more at lower floors and in buildings where balconies are close to neighboring structures, roofs or fire escapes. At higher floors the risk is lower, but a balcony slider that does not lock properly is still a weak point and a safety concern for children and pets. Fit a secondary lock where permitted.
Always check the association or landlord rules before changing hardware on a unit door. Many require approval, a key copy for the building or a specific finish. The condo door hardware rules page explains what to ask before anyone starts work.
A simple ranking worksheet
Walk around the home with a notepad. List each door, then score it from one to five on three questions. How hidden is it from the street and neighbors? How light is the door and frame? How old or worn is the lock? Add the three scores. The highest totals are your priorities.
Most homes end up with a similar pattern. The garage entry, the rear slider and one side door tend to rise to the top. The front door sits in the middle because it is visible even if its hardware is average. Interior doors and closets do not need to be ranked unless they hold valuables, medications or firearms, in which case a lockable cabinet or safe is a separate decision.
Share the worksheet when you call. It gives the technician a shorter route to understanding your home and makes the phone conversation more useful. If you have photos of each door and its lock, even better.
| Entry point | Common weakness | First thing to check |
|---|---|---|
| Front door | Decorative glass, soft frame | Strike plate screws and glass near the lock |
| Patio slider | Light latch, worn track | Does it catch fully and resist lifting |
| Garage entry | Hollow slab, basic knob lock | Slab type and deadbolt presence |
| Side or rear door | Poor lighting, old frame | Frame condition and lock alignment |
| Side gate | Latch reachable from outside | Whether a lock can be added |
| Condo unit door | Door does not self-close | Closer and latch engagement |
What a technician will look at when you call
When you ask for a review of your doors, the technician will usually start with what you tell them: the type of door, the type of lock, any problems and your worries. On site, they look at the slab, the frame, the strike plate, the latch and the cylinder. They check whether the lock turns smoothly, whether the bolt fully extends and whether the door closes without being pulled.
They may recommend repairs, such as a new strike plate with longer screws, or replacements, such as a new deadbolt. They may suggest rekeying if you are not sure who holds keys. They will explain the options and what each involves, and if the job is complicated, they will tell you it needs a visit and a written estimate through the phone conversation first. Quotes are given by phone, and a service call charge is explained before dispatch.
You can help by clearing the area around each door, having keys available and noting anything that has changed recently. If you are in a rented home or unit, have the landlord or manager's permission ready. For the order of events in a typical visit, see how a locksmith call works.
When to call rather than wait
Some door problems are inconvenient and can wait for a planned visit: a latch that is stiff, a cylinder that needs a squirt of the right lubricant, a handle that is slightly loose. Others are signals that the door is not doing its job. A deadbolt that does not fully throw, a frame that has split, a door that does not close on its own and a lock that turns without engaging are all in this category.
After a break-in attempt, a storm or any event that has struck the door, treat the entry as compromised until it has been checked. Even if the door appears intact, the frame may have cracked, the strike plate may have loosened or the bolt may be bent. Do not assume it will hold the next time. Check our page on lock repair after a break-in.
If you are unsure whether something is urgent, call and describe it. A short conversation can sort out whether it can wait. When you are ready to review your doors, call and we will talk through what you have and what would help.
Questions people ask
Which door in a house is the most likely to be a weak point?
It varies, but the garage entry door, the rear sliding door and quiet side doors are frequently weaker than the front door. They tend to have lighter hardware, less lighting and less visibility from the street. The best answer for your home comes from walking around and scoring each door on how hidden it is, how solid it is and how worn its lock is.
Should every exterior door have a deadbolt?
Most exterior hinged doors benefit from a deadbolt in addition to the handle lock, because a deadbolt provides a more solid bolt that is harder to force. Sliding doors use different hardware. Whether a double-cylinder deadbolt is appropriate depends on the door, glass nearby, and safety rules, so it is best discussed with a technician who can see the door.
Is my sliding door lock enough?
The factory latch on many sliding doors is light, and older units can often be lifted or shaken in the track. A secondary lock, a bar or a pin adds resistance. The track, rollers and latch condition all matter. If the door has become hard to lock or rattles in its frame, have it looked at rather than waiting.
Do I need to change locks on all doors at once?
Not necessarily. Many households start with the most exposed or most worn entry and work through the rest over time. After a move, a breakup or lost keys, rekeying all exterior doors at once is practical because it resets who holds keys. A phone conversation can help you decide the order and what can be combined into one visit.
What if I rent and cannot change my doors?
Check your lease and speak with the landlord or property manager. Many will approve lock changes or rekeying, and some prefer to arrange them. In the meantime, simple measures such as habits, lighting and a removable door bar for sliders are within most renters' control. Always get permission before work begins.
Can I send photos before calling?
Photos help you describe your doors, but quotes are given over the phone and complicated work may need an on-site look first. Take clear pictures of each door, the lock, the strike plate and any glass nearby, and have them to hand during the call so you can describe what you see.
Describe the situation by phone and we will tell you what the job involves. Quotes are given by phone. Jobs that cannot be quoted without seeing them need a technician on site, and the service call charge is explained on the phone before anyone is dispatched.
