What to Check After a Break-In Attempt Damages the Lock

September 12, 2026

A break-in attempt can damage much more than the visible face of a lock. Even if the door still closes and the key still turns, the lock, strike plate, frame, hinges, or surrounding hardware may have been weakened.

After any attempted forced entry, the priority is to determine whether the door can still secure the property reliably. A careful inspection can help identify hidden damage before the lock fails completely or the same entry point becomes vulnerable again.

Start With the Lock Itself

Look closely at the exterior and interior sides of the lock.

Scratches, dents, looseness, bent components, or damage around the keyway can all suggest that someone tried to pry, strike, drill, or manipulate the lock.

Test the key carefully. If the cylinder feels loose, the key is suddenly harder to turn, or the lock no longer operates smoothly, internal damage may be present even if the lock still functions.

A damaged lock should not be assumed secure simply because it still opens and closes.

Check Whether the Deadbolt Fully Extends

A deadbolt should extend completely into the strike plate without excessive resistance.

After a forced-entry attempt, the bolt may become bent or the door may shift enough that the bolt no longer lines up correctly.

Try locking and unlocking the door while it is open and then again while it is closed.

If the deadbolt works smoothly with the door open but becomes difficult when the door is closed, the problem may involve door or frame alignment rather than the lock mechanism itself.

Inspect the Strike Plate

The strike plate is the metal plate mounted to the door frame where the latch or deadbolt enters.

During a break-in attempt, this area can absorb considerable force.

Look for:

Bent metal
Loose screws
Cracked wood
Enlarged screw holes
Splintering around the frame
Movement when pressure is applied

A lock can be strong while the surrounding frame is weak. If the strike plate has pulled away from the frame or the wood around it has cracked, the door may no longer provide the same level of resistance.

Look Closely at the Door Frame

The frame often shows evidence of force before the lock itself does.

Check for cracks, separation, splintering, or sections that appear to have shifted.

Even relatively small frame damage can affect how the lock engages.

A damaged frame can also cause the door to sag or sit differently in the opening, which may explain why a lock suddenly feels tight or fails to latch properly.

Check the Hinges

Do not focus only on the lock side of the door.

Inspect the hinges for bent hardware, loose screws, or movement. Strong force against a door can affect the entire assembly.

If the hinges have shifted, the door may no longer hang squarely in the frame.

That can create alignment problems and make a properly functioning lock appear defective.

Test Every Exterior Lock

If someone attempted to enter through one door, it is wise to check the rest of the property.

Inspect other exterior doors, garage entry doors, gates, and accessible windows for signs of tampering.

Look for scratches, pry marks, damaged hardware, or locks that suddenly feel different.

A broader review can help determine whether the attempted entry involved a single point or several areas.

Consider Rekeying or Replacing the Lock

If the lock was physically damaged, replacement may be necessary.

Rekeying may also be appropriate in some situations, particularly if keys are missing or there is any reason to believe an unauthorized person could have obtained one.

The right solution depends on the condition of the hardware.

A locksmith can determine whether the existing lock remains serviceable, whether it can be repaired, or whether replacement with new or higher-security hardware makes more sense.

Do Not Ignore “Minor” Damage

A lock that still works after an attempted break-in may seem good enough.

The problem is that weakened internal parts, damaged mounting points, or a compromised frame may not fail until the next time the door is forced or even during normal use.

Addressing small problems early can help prevent a future lockout or security failure.

Restore Security Before Returning to Normal

After a break-in attempt, the goal is not simply to make the door close again. The entire locking point should be evaluated to make sure the lock, strike plate, frame, and surrounding hardware are still working together properly.

Why Modern Car Keys Are More Complicated Than They Look

September 2, 2026

A car key may still look like a simple object you carry in your pocket, but modern vehicle keys often contain far more technology than the metal keys used on older vehicles. Depending on the make, model, and year, a key may include a transponder chip, remote functions, proximity technology, or programming that allows it to communicate electronically with the vehicle. That added security and convenience also means replacing or troubleshooting a modern key can be more complicated than simply cutting a matching piece of metal. Many Keys Contain a Transponder Chip A transponder key contains a small electronic chip that communicates with the vehicle’s immobilizer system. When the key is inserted into the ignition or brought into the required position, the vehicle looks for the correct electronic signal. If that signal is missing or incorrect, the engine may not start even if the physical key turns normally. This is why a newly cut key can sometimes unlock a door but still fail to start the vehicle. The mechanical portion may be correct, but the electronic portion still needs to be properly programmed.

Why Employee Turnover Should Trigger a Security Review

August 27, 2026

Employee turnover is a normal part of running a business, but every staffing change can create a security issue if keys, access credentials, or entry permissions are not reviewed. Even when an employee leaves on good terms, business owners may not know how many physical keys were copied, which doors those keys open, or whether digital access is still active. A routine security review after employee departures can help businesses maintain better control over who can enter the property and which areas they can access. Start With Physical Keys Traditional keys remain common in offices, warehouses, retail locations, restaurants, and other commercial properties. When an employee leaves , the first step is usually collecting any keys that were issued. That may include keys for exterior doors, offices, storage rooms, filing areas, equipment rooms, or other restricted spaces. The challenge is that returning the original key does not guarantee that another copy does not exist. If there is uncertainty about how many copies may be in circulation, rekeying can provide a practical solution. Rekeying changes the internal configuration of the lock so the previous key no longer works, while allowing the existing lock hardware to remain in place when appropriate.

How Weather Affects Exterior Locks in the Pacific Northwest

August 21, 2026

Exterior locks in the Pacific Northwest deal with conditions that can gradually affect how smoothly they work. Frequent rain, damp air, cooler temperatures, and seasonal temperature changes can all influence door hardware over time. In Kitsap County, where moisture is a regular part of the environment, lock maintenance can be especially important. King’s Mobile Lock has served Kitsap County since 1972 and provides residential, commercial, automotive, and safe locksmith services. Understanding how weather affects exterior locks can help property owners recognize small problems before they turn into lockouts or hardware failures. Moisture Can Affect Lock Components Exterior locks are exposed to rain, humidity, and condensation. Over time, moisture can contribute to corrosion on metal components, especially if the hardware is older, damaged, or has lost some of its protective finish. Corrosion may make a key harder to insert or turn and can interfere with the movement of internal lock parts. Moisture can also collect around the latch, strike plate, or door hardware. If a lock suddenly feels rough or stiff after long periods of wet weather, that change deserves attention.
