Why the forgotten doors matter
When people think of security they picture the front door, since it is the one they use and the one visitors see. But a front door faces the street, usually has a light and is visible to neighbors. The doors at the side and back of a house, and the one that leads from the garage to the kitchen or hallway, are often the opposite. They are tucked out of sight, they carry older or lighter hardware and they are routinely left unlocked because they feel inside the property.
The garage entry door is a clear example. The thinking goes that the garage door is closed, so the interior door can be left unlocked. But a garage door can fail, be left open, be opened with a lost remote or be bypassed in other ways, and then the door from the garage to the house is the only barrier left. If it is a hollow interior-style door with a thin latch, it protects very little.
This guide takes each of these openings in turn: the overhead garage door, the entry door from the garage, side doors and gates, and the habits that tie them together. Work through them one at a time and note what you find. Most of the improvements are small and practical.
The door from the garage into the house
This door deserves the same standard as an exterior door, since in practice it is one. Check that it is a solid door, either solid wood, steel or a similar strong material, and not a thin hollow door. Check that it has a deadbolt in addition to the handle latch, and that you actually use it. Many homes were built with only a knob lock on this door, and adding a deadbolt is a common and worthwhile upgrade.
Look at the frame and strike plate. A deadbolt is only as strong as the wood or metal it bolts into. If the strike plate is held with short screws into thin trim, it can fail under force, and longer screws that reach the framing behind improve it. Our page on door reinforcement and strike plates explains this in more detail, and the page on garage entry door locks describes typical hardware choices.
Consider the hinges as well. If the door opens outward into the garage, hinge pins may be on the outside where they can be reached, and a technician can fit security pins or choose a different arrangement. Do not try to alter the hinge side of a door in a way that affects how it closes unless you are confident, because a misaligned door will not latch.
Finally, look at the fit. A door that sags, rubs the frame or does not latch without a shove will not protect you however good the lock is. Humid conditions can swell doors and frames. If your door has begun to stick, have it looked at. A technician can adjust or repair it, and a lock that lines up with its strike will wear more evenly.
- Is the door solid, not hollow?
- Is there a deadbolt, and is it used every night?
- Are strike plate screws long enough to reach the framing?
- Do the hinges sit on the protected side or have security pins?
- Does the door close and latch without a shove?
The overhead garage door and its opener
The big door is often the largest opening in the house. Most people rely on the opener to keep it closed, and the opener's controls are the security. Remotes in cars are the main weakness: a remote left in an unlocked vehicle in the driveway is a way into the garage. Take remotes out of cars parked outside overnight, or keep the car locked and the remote out of sight. If you lose a remote, reset or reprogram the opener so that the missing one stops working.
Check whether your opener uses a fixed or a changing signal. Older models used a fixed signal that could be copied, while modern ones change the signal each time. If your opener is very old, consider asking a garage door professional about a newer model. Our site focuses on locks and keys, but this is a worthwhile question to raise with the installer.
Most openers have a release cord on the carriage that lets you open the door by hand when power is out. On some doors that cord can be reached from outside through a gap at the top. Ask a garage door professional whether yours can be shielded. Do not touch the springs, cables or brackets on a garage door. They hold stored tension and can cause serious injury. Leave all spring and cable work to a trained garage door technician.
Also check the manual lock on the door, if there is one. Many garage doors have a simple side lock or a bolt that can be engaged when you are away for an extended period. It will not be needed day to day, but when you travel it adds a measure of safety, as long as you disengage it before using the opener. Our page on home security before you travel covers this.
Side doors: lighting, visibility and hardware
Side doors and back doors are used for convenience: taking out the garbage, reaching the yard, bringing in groceries from the driveway. They often have an older lockset, a plain latch with no deadbolt and a flimsy storm or screen door in front. They are also the doors least likely to be seen by neighbors, since they sit between houses or behind landscaping.
Begin with visibility. Is the door lit at night? Is there a motion light covering it? Are shrubs, trellises or stored items blocking sight lines? Cutting back vegetation and adding a light often improve the situation more than any hardware change. Our page on cameras, lighting and locks together explains how these pieces fit.
Then look at the hardware. Fit a good deadbolt, check the strike plate and frame, and consider a door that is solid and well hung. If the door has glass in or near it, notice whether someone could break the glass and reach the lock from inside. If so, a keyed deadbolt on the inside, kept with a key stored nearby but not in the lock, can help. Be careful with this idea: in an emergency everyone in the house must be able to leave quickly, so keep the key easy to reach and make sure every household member knows where it is.
In Miami-Dade, side doors often face walls or fences that trap humidity, and hardware here wears faster. If a lock turns hard, sticks or feels gritty, do not force it. See salt air and humidity lock wear for what to look for.
Gates, fences and the path to the back yard
A side gate is the first barrier between the street and the back of the house. A gate that is open, unlatched or fitted with a weak latch invites people into the yard, where they can try the rear doors in private. A closed and locked gate does not make a yard impregnable, but it forces a person to climb or break something, which is more noticeable and harder to do quickly.
Check the gate latch and hinges. Latches rust and loosen in the humid climate, and gates can sag. A latch that lets a gate swing slightly open when closed is a poor barrier. A lockable gate latch or a simple padlock arrangement, kept locked when you are not using the yard, is often enough. Our page on residential gate locks goes into detail.
Think about what the gate hides. If there are bins, ladders or tools behind it, a thief may use them. Store ladders inside, and secure tools. If you have a pool, remember that pool gate rules exist for safety reasons, so any change to a pool barrier gate must keep it self-closing and self-latching as required. Do not replace those latches with something that stays open.
In a community with shared gates, the association manages them. Report problems such as latches that do not catch or gates that are propped open. Our page on gated community and guard gate locks explains the typical arrangement.
Sliding doors and patio entries as side entries
Many homes in the area have a sliding glass door facing the yard or the pool. It is a side entry in every sense that matters. Sliding doors have a simple latch that can often be lifted or forced, and the door may be lifted out of its track if it is not secured. Keep a bar or dowel in the track when the door is closed, and check that the latch catches fully.
Look at whether the door is impact rated or fitted with security glass, as many are in this region after storm-related building rules. If it is a plain glass door, consider a locksmith's advice on a secondary lock or a better latch. Our page on sliding glass door locks and patio door security upgrade explain the options.
Never leave a sliding door open on the chain or with the screen only. A screen door is not a barrier. If you want ventilation, use a ventilation lock that holds the door open a few inches, only when you are home and awake.
Daily habits that matter more than hardware
A good lock does nothing if it is not locked. The garage entry door is the classic example: people are home, the garage door is down and the interior door is left open because it is convenient. Make a habit of locking the garage entry door every night, and when you leave the house, even for a short time. Teach children and visitors the same habit.
Close the garage door whenever you are not actively using it. An open garage door with a car and tools inside is an invitation, and leaving it open while you are in the yard gives someone a chance to walk in unnoticed. If you struggle to remember, some openers can close automatically after a set time or can alert you when the door is open.
Do not leave valuables visible in cars in the driveway. Keep spare keys, garage remotes and anything that identifies the house out of vehicles. Keep ladders and tools inside. Review who has remotes and keys now and then. If you have lost track, a rekey of the entry doors and a reset of the opener resets everything. Our page on key control for families describes a simple way to keep track.
What to leave to professionals
Some of these improvements are simple for an owner, such as trimming shrubs, adding a light, changing the habit of locking up or storing a ladder. Others are better done by a trained person. Fitting a deadbolt into a door, aligning a strike plate, repairing a frame and fixing a door that has dropped all involve cutting or adjusting, and a mistake can leave the door less secure than before.
Garage door springs, cables and brackets belong to garage door technicians, who have the tools and training to handle the stored tension safely. Do not attempt to adjust or release them yourself. If your garage door is off its track, sticks or makes unusual noises, call a garage door professional. If the problem is the lock on the entry door or a side gate, that is where a locksmith comes in.
When you call a locksmith about these doors, describe what you have: the door material, whether there is a deadbolt, how it sticks or fails and whether the door faces the garage, the side yard or the back. Photographs help, and our page on photos that help a locksmith explains which angles are useful. For a simple lock job, the price is given on the phone. For a door that needs work on the frame or a number of doors at once, an on-site look comes first, and a service call charge is explained before dispatch.
A walk-around checklist for your property
Take twenty minutes, walk the outside of the house in daylight and again at dusk, and use the list below. Note what you find and tackle the biggest weak points first. Return to the list each season, since landscaping grows, hardware wears and habits slip.
If you find several problems, plan the work in a sensible order. Our guide on planning a multi-door lock project shows how to group the doors so a technician can address them in one visit. When you want to talk through the doors and gates on your property, call and describe what you see, and a dispatcher can explain how a visit would work.
- Check the garage entry door: solid, deadbolt, strike plate, fit.

- Check side and back doors for a deadbolt and a light.
- Check gate latches, hinges and what the gate hides.
- Check sliding doors for a track bar and a working latch.
- Cut back plants that block sight lines to doors and windows.
- Store ladders and tools inside, and take remotes out of parked cars.
Questions people ask
Does the door from my garage to the house need a deadbolt?
It should be treated like an exterior door. A solid door with a deadbolt, a firmly anchored strike plate and a good fit is a sensible standard. If the garage door fails or is opened with a lost remote, that interior door is the remaining barrier. Many older homes only have a knob lock there, which is worth upgrading.
Is it safe to leave the garage entry door unlocked when I am home?
It is a common habit, but it removes a barrier you may rely on if the garage door is open or its remote is missing. Locking it every night and whenever you leave takes a moment. If the key is a nuisance, consider hardware that is easy to use rather than leaving it unlocked.
Can I fix my garage door springs myself?
No. Springs, cables and brackets hold a lot of tension and can cause serious injury. Leave them to a trained garage door technician. A locksmith can help with the lock on the entry door, the side doors and gates, but not with the spring or cable system of an overhead door.
What should I do about a lost garage remote?
Treat it as a lost key. Reset or reprogram the opener so the missing remote stops working, following the manufacturer's instructions or asking a garage door professional. Do not leave remotes in cars parked outside overnight, and if you also lost house keys with it, consider rekeying the entry doors.
How can I make a side door safer without replacing it?
Improve the light and visibility first, then check the lock. A good deadbolt, longer strike plate screws and a firm frame help a lot. Remove anything that lets someone hide near the door, and make sure you lock it every night. A technician can inspect the door and tell you whether repair is enough.
Do pool gates have their own rules?
Yes. Barriers around pools are typically required to be self-closing and self-latching for safety, so any change to the latch must keep that function. Do not swap in a latch that stays open or can be propped. If a pool gate latch fails, have it repaired so it works as intended and keep children away until it does.
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.
