Common Issues

Problems We Solve

Real issues our customers face — and exactly how we fix them.

Outdated or Worn-Out Locks
Problem #1

Outdated or Worn-Out Locks

The Issue

Locks older than 7 years have degraded internal pins that can be defeated with bump keys or basic picking tools.

Our Solution

We replace aging hardware with modern Grade 1 or Grade 2 deadbolts that resist bumping, picking, and forced entry.

Unaccounted Spare Keys
Problem #2

Unaccounted Spare Keys

The Issue

Previous owners, ex-roommates, or past contractors may still have working keys to your home.

Our Solution

Full rekeying gives you exclusive key control — every existing key becomes useless, and only you get the new ones.

No Smart Lock or Keyless Entry
Problem #3

No Smart Lock or Keyless Entry

The Issue

Still fumbling with physical keys? No way to grant temporary access or see who entered your home.

Our Solution

We install and configure smart locks with app control, temporary codes for guests, and full entry logging.

Residential Locksmith Warning Signs

Old or Worn-Out Locks

Locks older than 7 years may have degraded internal pins, making them easy targets for bump keys.

Urgent

Spare Keys Unaccounted For

Previous owners, ex-roommates, or contractors may still have keys. Rekeying gives you exclusive control.

Urgent

Sliding Door Gaps

Sliding doors are the #1 residential break-in point. A secondary lock or security bar prevents forced entry.

Urgent

No Smart Lock or Keypad

Modern smart locks let you grant temporary access, see entry logs, and lock remotely. Affordable upgrade options available.

Urgent

Weak Window Locks

Standard window latches can be pried open in seconds. Pin locks and key locks add serious resistance.

Urgent

Single-Lock Entry Doors

A deadbolt combined with a door knob lock creates two-point security — exponentially harder to defeat.

Common Questions

Residential Locksmith FAQ

Should I rekey or replace my locks?

Rekeying is a precision procedure that alters the internal logic of your lock cylinder, rendering old keys useless while maintaining your existing hardware.. We recommend replacement only if your hardware is structurally compromised, mechanically fatigued, or if you require an upgrade to high-security or smart-locking platforms.

What are bump-proof or pick-resistant locks?

These locks have special pin configurations that defeat common lock-picking techniques. Brands like Medeco and Mul-T-Lock are excellent options. We recommend them for front doors and any entry visible from the street. {city} families choose us for dependable home security service.

What lock options are best for homes with small children?

We recommend locks with interior thumb-turns (no key needed to exit — critical for fire safety), child-proof deadbolt covers for curious toddlers, and smart locks with auto-lock features.. We can also install chain guards at adult height for additional interior security.

What grade of deadbolt should I use for my home?

We recommend Grade 1 or Grade 2 deadbolts for residential use. Grade 1 offers the highest security and is what we install on most homes. Grade 3 is builder-grade and adequate for interior doors only. Let us assess your needs. We bring professional-grade home security solutions to {city} residents.

Can you reinforce my door frame for better security?

Yes.. A quality deadbolt is only as strong as the frame holding it.. We install reinforcement kits with 3-inch screws that anchor into the wall stud, strike plate reinforcements, and door edge guards.. This dramatically increases kick-in resistance.

Should I have a deadbolt on my garage entry door?

Absolutely.. The door from your garage to your home is the most common break-in point.. Once inside the garage, burglars work hidden from view.. We recommend a high-quality deadbolt and solid-core door for this entry point.
