How Long Does It Take to Break Into a House? A Door-by-Door Breakdown

A common assumption about home security: a good deadbolt lock keeps burglars out. The lock is the last line of defense, so it must be the thing that matters.

Here’s the problem. Most residential doors can be kicked open in under 10 seconds regardless of the deadbolt. Not because the lock fails — because the door frame does. Understanding exactly how long each entry point takes to breach, and why, changes every decision you make about home security.

Why Entry Time Is the Number That Matters

Burglars are optimizing for one thing above all else: not getting caught. The longer they spend gaining entry, the higher the risk — noise, visibility, time for a neighbor to notice. Research from the International Association of Certified Home Inspectors confirms that burglars prefer easy targets and aim to be in and out as quickly as possible. Most break-ins happen in under 10 minutes total. The initial breach? Often under 60 seconds.

This means every second you add to entry time has compounding value. A door that takes 10 seconds to kick in versus one that takes 45 seconds isn’t just “harder to break” — it’s in a completely different risk category for an opportunistic burglar deciding whether to attempt it.

Entry Point #1: The Front Door

⏱ Standard: under 10 seconds

34% of all residential burglaries use the front door as the entry point — more than any other. Yet most homeowners assume a deadbolt makes this door secure. It doesn’t, unless the frame is reinforced.

Here’s the mechanical reality: a standard residential door frame is made of softwood trim approximately 1.5 inches thick. Your deadbolt bolt extends into that wood and is held by a strike plate attached with 3/4-inch to 1-inch screws. A single well-placed kick at the lock area generates enough force to split the wood trim, rip the strike plate out, and open the door — regardless of the lock grade. The FBI identifies door frame failure as the mechanism in approximately 70% of all forced entries.

Consumer Reports tested nearly two dozen residential door locks. Only 6 of those locks could resist repeated impacts with the hardware they came with. But when secured with a box strike and longer screws, every single model became highly resistant to kick-ins. The lock isn’t the variable. The frame attachment is.

Entry Point #2: The Back Door

⏱ Standard: under 10 seconds

Back doors account for 22% of residential burglaries and share the same frame vulnerability as front doors — with two compounding problems. First, back doors are typically less visible to neighbors and the street, giving a burglar more time to work without being noticed. Second, they’re frequently fitted with lower-quality locks and lighter doors than the main entrance.

Security professionals consistently note that secondary entrance doors often receive the minimum security investment — a basic knob lock or a cheaper deadbolt — while homeowners focus their budget on the front. A back door with a hollow-core construction and a Grade 3 deadbolt (rated to withstand only 2 kicks of 75 lbs) is meaningfully weaker than a solid front door even before frame strength is considered.

Back doors in less-visible locations — facing a fence, in a recessed patio, or behind hedges — warrant particular attention. The concealment that makes them pleasant for privacy makes them preferable targets for forced entry.

Entry Point #3: Ground Floor Windows

⏱ Unlocked: 5–15 seconds | Locked standard: 15–30 seconds | Glass break: 3–5 seconds

Windows account for 23% of all burglary entries, and the entry time breakdown reveals why they’re dangerous in multiple distinct ways depending on the scenario:

• Unlocked window: 5–15 seconds. Simply push up, climb through. No tools, no noise. This scenario is far more common than most people think — during warmer months, the rate of window entries increases sharply because windows are left open or unlatched.
• Standard latched window: 15–30 seconds. A standard window latch is designed to keep the window from sliding open accidentally, not to resist a deliberate attempt to force it. A screwdriver between the sash and frame typically defeats it quickly.
• Breaking the glass: 3–5 seconds to break; then 10–20 seconds to reach in and open, or climb through. Glass breaking is noisier and riskier for the burglar — most prefer the unlocked or forced latch approach — but standard single-pane glass offers essentially zero resistance.

The critical nuance: most windows are not equipped with actual locks, only latches. A latch prevents casual sliding. A lock resists deliberate force. These are not the same thing.

Entry Point #4: Sliding Glass Doors

⏱ Standard latch only: 10–20 seconds | With security bar: significantly harder

Sliding glass doors have two distinct vulnerabilities that make them among the weakest entry points in a typical home.

First vulnerability — the latch: The standard factory latch on a sliding door is easy to force with a screwdriver or jimmy tool. Unlike a deadbolt that extends into a reinforced strike, the sliding door latch engages a plastic or light-metal catch that offers minimal resistance to lateral force. Many can be defeated in one motion.

Second vulnerability — lifting off the track: Older sliding doors, and some newer models with worn track hardware, can be physically lifted out of their bottom track and swung inward or outward — bypassing the latch entirely. This requires no tools and takes 10–20 seconds once a burglar identifies the gap. Homeowners with older sliding doors rarely know this is possible until they test it themselves.

Entry Point #5: The Garage

⏱ Emergency release attack: 6 seconds | Via attached interior door: varies

The garage accounts for 9% of burglary entries, and there’s a specific attack method that’s widely known among security professionals but almost unknown to homeowners: the emergency release cord exploit.

Every garage door opener has a red emergency release cord that disconnects the door from the drive mechanism, allowing manual operation. This is an essential safety feature for power outages. It’s also exploitable. A burglar can slide a wire hook through the gap at the top of the garage door frame — typically a 1–2 inch gap that exists even in closed doors — catch the emergency release cord, and pull it. The garage door is now disconnected from the opener and can be manually lifted. This attack takes approximately 6 seconds with a pre-bent wire.

The second garage vulnerability: the door connecting the garage to the house interior. This door is typically treated with far less security than exterior doors — sometimes a basic knob lock or even just a latch — because homeowners assume the garage itself provides the outer security layer. When the garage is compromised, this interior door becomes the actual barrier to the living space, and it’s often the weakest door in the house.

The Priority Order: Where to Start

If you’re upgrading your home security based on this breakdown, here’s the order that delivers the most improvement per dollar:

1. Reinforced strike plates on front and back doors ($20–40 each). This addresses the most common entry point and the most common failure mechanism. The ROI on this upgrade is unmatched.
2. Window track locks or pins ($5–10 each). Cheap, fast to install, and converts window latches into actual locks. Do every ground-floor window.
3. Sliding door security bar ($15–25). Defeats the most common sliding door attack completely.
4. Garage emergency release defender ($2–10). Extremely cheap fix for a surprisingly common vulnerability.
5. Entry sensors on windows and secondary doors ($10–15 each). These don’t prevent entry but they cut response time — when entry is detected immediately, a burglar’s usable time inside drops from 8–12 minutes to under 2.

The Honest Summary

The entry time data points to the same conclusion from every angle: the lock is rarely the problem. The frame, the latch, the track, the cord — these are what fail first. Most of the high-impact fixes are cheap and fast. A reinforced strike plate costs $25 and 20 minutes. A window pin costs $5. A garage release defender costs $2.

The security industry sells complexity. The entry time data says the basics — done properly — are what actually close the gap. A $3,000 alarm system in a house with standard strike plates is a less secure house than one with $100 in hardware upgrades and no alarm at all. Do the hardware first.

Once the physical hardening is in place, detection layers — cameras, sensors, a monitored alarm — provide the remaining coverage.
