Garage Door Locks Repair

A broken garage door lock creates an urgent security problem. It leaves you in one of two situations: your garage is stuck locked, trapping your car, or it’s stuck unlocked, leaving your home vulnerable. This is especially true for manual doors or if a manual lock interferes with an automatic opener.

At Alfonso Garage Door, we specialize in repairing and replacing all types of garage door locks, from traditional T-handles and key cylinders to slide latches. We provide fast, same-day service throughout the Bay Area to secure your home or get you back inside.

The Telltale Signs of a Broken Lock

Lock failures can be mechanical (rust, wear) or user-related (jamming). Here are the common symptoms.

Symptoms of a Lock Problem:

Key is Stuck or Broke Off

This is a common and frustrating problem. The key is stuck in the lock cylinder, or you’ve applied too much force to a stuck lock, and the key has snapped off.

Key Spins but Won't Lock or Unlock

You can insert the key, and it turns freely in the cylinder, but the locking mechanism never engages or disengages. This means the internal parts are broken or disconnected.

Handle or Latch is Rusted or Jammed

The T-handle on the outside is frozen with rust and will not turn. Or, the manual slide latch on the inside is rusted to its track and cannot be moved.

Can I Fix It Myself?

This is a tricky area. Some lubrication is safe, but most lock repairs are not.Yes! Keypad issues are among the safest and easiest for a homeowner to troubleshoot. Before you call, we highly recommend you try these steps.

Safe DIY Checks:

Lubrication: If a lock is just “sticky,” you can try a graphite-based lock lubricant. Do not use WD-40, as it attracts dust and gums up the lock.
CHECK FOR OPENER INTERFERENCE: This is the most important check. If your opener isn’t working, make 100% sure the manual slide latch or T-handle lock is disengaged before you try again.

Why You MUST Call a Professional

Key Broke Off: You will need a special tool to extract the key bit.
Lock is Jammed: Forcing it will damage the door panel.
If You Have an Opener: A professional will (and should) recommend disabling the manual lock to prevent it from ever damaging your opener.
Replacement: Replacing a lock cylinder or handle often requires drilling and precise alignment.

What to Do Right Now If Your Lock is Broken

Follow these steps in order:

Step 1: Stop. Do not force the key or handle. You can snap the key or bend the door panel.
Step 2: If you have an automatic opener, check that the manual lock is fully disengaged.
Step 3: If the lock is frozen, try a lock-specific de-icer or graphite lubricant.
Step 4: If you are locked out, do not break a window. It's safer and cheaper to call us.
Step 5: Call a professional. Contact Alfonso Garage Door at (408) 580-7949 for lockout or repair service.

How Long Does Lock Repair Take?

This is almost always a very fast, same-day repair.

Typical Repair Timeline:

Our technicians carry a stock of common lock assemblies and extraction tools to solve the problem on the first visit.

Preventing Future Lock Problems

Hinge failure is almost always preventable with one simple task: lubrication.

Common Causes of Failure:

Age & Rust: The lock is old and the internal parts have corroded.
Lack of Lubrication: The pins and tumblers are dry and create friction.
Opener Interference: The lock was engaged, and the opener was used, breaking the lock or the door.
Forced Key: Jamming the wrong key in or forcing a stiff lock.

A Seasonal Warning for Homeowners

Moisture and ice are the main culprits. Rain and humidity cause the lock’s internal pins to rust and seize. On freezing nights, any moisture inside the cylinder will freeze, jamming the lock completely. Homeowners then try to force the key, and it snaps off. If your lock is stiff, use a graphite lubricant or a de-icer, never force it.

Frequently Asked Questions

My garage opener hums but won't open. Is it the lock?

It is very likely the problem. Immediately stop using the opener. Go inside and check if your manual T-handle or slide latch is engaged. If it is, disengage it and try again.

Should I use my manual lock if I have an automatic opener?

NO. We strongly recommend you do not use the manual lock. The opener itself is the lock. Engaging the manual lock and then running the opener can destroy your opener or your door panels.

My key broke off in the lock. Can you fix it?

Yes. We have special tools to extract the broken part of the key. We can then either repair or replace the lock cylinder.

What kind of lubricant is safe for locks?

Use a graphite-based powder or a lock-specific spray. Do not use oil-based lubricants like WD-40, which will attract dust and gum up the lock pins.
