Window Lock Repair
in Auburn, WA

A broken window lock isn't just an inconvenience — it's a security gap. Auburn Lock & Car Keys repairs and replaces window locks, sash locks, sliding window latches, and casement crank mechanisms on residential windows across Auburn.

Window Locks Get Overlooked — Until They Fail

Window locks see less use than door locks but they wear out the same way. Springs weaken. Catches break. Plastic latches snap. Cranks strip out. And then on a hot summer night, you can't actually secure the window you want to crack open — or it won't close all the way when you do.

Window types we service for Auburn-area homes:

Window Types & Lock Styles We Repair

  • Double-hung windows — the classic up-and-down design. Sash locks, lifts, and sash balances all wear with use.
  • Sliding (horizontal) windows — latches, security bars, and lift locks for windows that slide left/right.
  • Casement windows — crank-out windows. Crank mechanisms strip, multipoint latches fail, and operators seize.
  • Awning windows — top-hinged crank-out windows. Similar mechanisms to casements.
  • Single-hung windows — bottom sash moves, top is fixed. Sash lock and balance issues.
  • Tilt-and-turn windows — European-style multipoint locking, found in some newer builds.
  • Vinyl, wood, aluminum, & fiberglass — all common Pacific Northwest window materials.

Common Window Lock Repairs

  • Replacing broken sash locks (the cam lock at the middle of double-hung windows)
  • Repairing or replacing casement crank operators and handles
  • Installing window security pins for windows that need to stay slightly open but secure
  • Replacing broken or seized sliding window latches
  • Adding aftermarket window locks for older windows with no factory lock
  • Replacing failed sash balances (the springs/cords that hold the window up)

Window Security Upgrades

Beyond simple repairs, we can also upgrade window security with pin locks, security bars, keyed window locks, sash stops, and ventilation locks that let windows open partially but not enough for entry. Especially valuable for ground-floor windows and any windows accessible from a porch roof or fence.

When You Need This Service

Common Reasons Auburn Homeowners Call Us

Sash Lock Broke

The cam lock on a double-hung window snapped off or won't engage. One of the most common window repairs we do.

Casement Won't Crank

Stripped crank, broken operator, or seized hinge. We have replacement operators for major brands.

Slider Latch Won't Catch

Sliding window doesn't lock anymore. Cheap plastic latches wear out — we replace with quality metal alternatives.

No Original Lock

Older windows without proper locks? We can add aftermarket sash locks and security pins for very little money.

Our Process

How Window Lock Repair Works

Window lock repairs are usually quick and inexpensive — most done in a single visit.

01

Identify the Window

Tell us the type and ideally the brand (Andersen, Pella, Milgard, etc.). A photo of the broken part helps us bring the right replacement.

02

Diagnose On-Site

We inspect the lock, the operator, and surrounding hardware. Sometimes it's a $15 part, sometimes a full unit replacement.

03

Repair or Replace

We carry common sash locks, latches, and crank handles in our service vans. For brand-specific parts we may order and return same-day.

04

Test & Secure

We cycle the lock or crank, verify smooth operation, and lubricate adjacent hardware while we're there.

FAQ

Window Lock Repair Questions

Simple sash lock replacements run $45 to $95 per window including parts. Casement crank operators with brand-specific parts run $95 to $200. Multi-window service calls are discounted per window. We give exact pricing once we know the brand and what's broken.
Usually yes. The crank handle, the operator (the gear box inside the frame), and the hinges all wear out over time. Most casement crank failures trace to the operator, which is a replaceable part we can install on-site for most major brands.
Yes. Older Auburn homes often have wood-frame double-hung windows with original 50+ year old sash locks. We can replace the lock cleanly without damaging the frame, or upgrade to a more secure modern style if you want.
Yes — we install aftermarket sash locks, pin locks, security bars, and keyed window locks on virtually any window type. Especially valuable for ground-floor windows that came without proper locks (more common than you'd think on older homes and inexpensive builds).
Yes — that's a sash balance issue, not a lock issue, but we handle both. The springs or cords that hold a double-hung window in the open position can fail with age. We replace sash balances on most window brands.
Absolutely — this is one of our most-requested window upgrades. Vent locks (or 'sash stops') let the window open 3 to 4 inches for airflow but physically prevent it from opening further. Great for bedrooms in summer.
