🔑 5 Common Lock Problems and How to Fix Them (Or When to Call a Locksmith in Ayer, MA)

Locks are something most people don’t think twice about—until they stop working. Whether it’s a stubborn deadbolt or a key that just won’t turn, common lock problems can be a serious headache, especially when you’re in a rush. At C and J Lock, we’ve seen it all. Here are five of the most common lock issues we help people with in Ayer, MA, and what you can do about them.

1. Key Won’t Turn in the Lock

This is one of the most common calls we get. You put your key in, but the lock won’t budge. Sometimes the key doesn’t even go all the way in.

Possible causes:

  • The key or lock is worn out

  • The lock cylinder is misaligned

  • Dirt or debris inside the lock

What you can try:

  • Wiggle the key gently—don’t force it

  • Use a PTFE-based lubricant like Super Lube or Tri-Flow (avoid graphite or WD-40)

  • Try a spare key if you have one

When to call a pro:
If the problem happens repeatedly or the key breaks off in the lock, it’s time to call in a locksmith. For homes and businesses in Ayer, we can often rekey or replace the lock on the spot.

2. Door Lock is Sticking or Hard to Turn

If your door lock works, but only after some struggling, you could be dealing with wear and tear or weather-related swelling—especially during New England’s humid summers or freezing winters.

What you can try:

  • Apply a PTFE-based lock lubricant

  • Check door alignment—sometimes tightening the hinges or adjusting the strike plate helps

When to call a locksmith:
If you’ve done some DIY and the issue persists, the internal mechanism might be damaged. At C and J Lock, we can diagnose and fix the issue before it becomes a full-blown lockout.

3. Key Broke Off in the Lock

This one always happens at the worst time—like right before work or while locking up at night.

What you can try:

  • If part of the key is sticking out, gently pull it out with needle-nose pliers

  • Don’t try to jam anything into the lock or use glue (yes, people try it!)

Why a locksmith is the safest bet:
We have the right tools to remove the broken key without damaging your lock. If needed, we can cut you a new key on the spot and inspect the lock to make sure it’s not about to break again.

4. The Lock Turns But Doesn’t Unlock

This usually means the tailpiece or cam inside the lock isn’t connecting properly.

What’s going on:

  • Something is broken internally

  • The lock has been rekeyed incorrectly

  • The lock is old and the parts are worn

Solution:
This isn’t usually a DIY fix. We can repair or replace the internal parts, or swap out the entire lock if it’s time for an upgrade.

5. Loose Doorknob or Deadbolt

If your doorknob or deadbolt feels wobbly, don’t ignore it—loose hardware can make your home easier to break into.

Quick fix:

  • Tighten the screws on the faceplate or knob (you may need to remove the cover plate first)

If that doesn’t work:
The lock may be coming apart inside or was improperly installed. We can repair it or recommend a better-fitting lock for your door.
