Door lock repair service in Philadelphia: Fix it before it breaks

Lock repair vs lock replacement: What's the difference?
People call us asking “do I need a new lock?” Often the answer is no. Your lock can probably be repaired.
Lock repair means we fix what’s broken or worn on your existing lock. We replace worn pins, realign strikes, lubricate mechanisms, tighten loose hardware, adjust door alignment. Your lock stays in place, we just make it work properly again.
Lock replacement means removing your entire lock and installing a new one. This is necessary when the lock is severely damaged, broken beyond repair, or you’re upgrading security.
Repair costs less. Typically $100 to $200 versus $150 to $350 for replacement. If your lock can be repaired, that’s the smart move financially.
When we arrive, we diagnose honestly. If repair makes sense, we repair. If replacement is actually needed, we explain why and quote you fairly. We’re not trying to sell you a new lock if your current one can be fixed. For situations where replacement is necessary, check our lock replacement service.
Common lock problems we repair
Key is hard to turn or won’t turn
The most common complaint. You insert your key and it won’t turn. Or it turns but requires force. Usually caused by worn pins inside the cylinder, dried lubricant, or debris buildup.
This is very repairable. We clean the cylinder, replace worn pins if needed, lubricate properly, and your key turns smoothly again.
Lock is sticky or catches
Your lock works but feels sticky. It catches when you turn the key. You have to wiggle it. The mechanism isn’t smooth.
Usually fixable with cleaning, lubrication, and sometimes replacing worn internal springs or pins. We restore smooth operation without replacing the entire lock.
Bolt won’t extend or retract smoothly
You turn the lock but the deadbolt doesn’t move smoothly. It sticks, catches, or doesn’t fully extend or retract. Could be worn bolt mechanism, misaligned strike plate, or debris in the bolt channel.
We diagnose which component is causing the problem and repair or adjust accordingly. Often the strike plate just needs realignment as the door has settled over time.
Door won’t close or latch properly
Your door doesn’t close right. You have to lift it or push hard to get it to latch. The lock bolt doesn’t catch in the strike plate properly.
Very common in Philadelphia’s old rowhomes. Buildings settle over decades. Doors and frames shift slightly. The lock and strike plate get misaligned. We realign everything so your door closes smoothly and locks securely. No new lock needed.
Key gets stuck in lock
Your key goes in fine but gets stuck when you try to remove it. Or it’s hard to pull out. Usually worn cylinder pins gripping the key, or the key itself is worn and catching.
Often we need to address both the lock and the key. Replace worn pins in the cylinder, cut your fresh keys from code. Problem solved.
Lock feels loose or wobbly
The lock hardware wiggles. It doesn’t feel solid and secure. Mounting screws have loosened, the strike plate has shifted, or internal components are worn.
We tighten mounting hardware, replace stripped screws if needed, realign strike plates, and stabilize the lock mechanism. Your lock feels solid again.
Lock makes noise when turning
Grinding, clicking, or scraping sounds when you turn the key. Internal components are rubbing or worn. Dried lubricant or debris causing friction.
Usually repairable with thorough cleaning, proper lubrication, and replacing worn components that are creating the noise.
Smart lock isn’t working right
Your electronic deadbolt or smart lock is malfunctioning. Won’t connect to the phone, the keypad doesn’t respond, the motor makes noise but doesn’t work, or it’s just acting weird.
We diagnose smart lock problems: battery issues, wiring problems, sensor failures, motor failures, connectivity issues. Many are repairable without replacing the entire expensive smart lock unit.
Lock works but doesn’t feel secure
Your lock functions but doesn’t feel right. The bolt seems loose, the door has too much play when locked, or you just don’t feel secure.
We assess strike engagement, bolt condition, frame alignment, and overall security. We tighten, adjust, and reinforce to restore your confidence in your lock’s security.

When repair isn't enough: When you need replacement
We’d rather repair your lock and save you money. But honesty matters. Sometimes replacement is necessary:
Lock cylinder is cracked or broken: Physical damage to the cylinder body can’t be safely repaired. Structural integrity is compromised. Needs replacement.
Someone forced the lock in a break-in attempt: Even if the lock still sort of works, the internal mechanism has been stressed and damaged. Security is compromised. Replace it. For emergency situations after break-ins, see our emergency locksmith services.
Locks are old and parts don’t exist: Some really old locks, especially in century-old Philadelphia properties, can’t be repaired because replacement parts aren’t manufactured anymore. Time to upgrade.
Multiple internal failures: If several components are worn or broken simultaneously, the repair cost approaches replacement cost. At that point, better to replace with new quality hardware.
You want to upgrade security level: If your current lock is basic builder-grade and you want high-security cylinders or smart locks, repair won’t help. You need new hardware. Check our lock installation service for upgrades.
Severe corrosion or rust: Philly weather can destroy exterior locks over time. If corrosion is deep and structural, replacement is safer than attempting repair.
We assess honestly when we arrive. If repair is the smart choice, we repair. If replacement makes more sense, we explain why clearly and quote you fairly. You decide.

The door lock repair process: What to expect
We arrive and inspect thoroughly
When we get to your location, we inspect your lock, door, frame, strike plate, and keys. We ask about the problem: when it started, how it’s behaving, what symptoms you’re experiencing.
We test the lock operation. We assess all components to determine what’s causing the malfunction.
We diagnose the problem
Based on inspection and testing, we diagnose the issue. Worn pins, misaligned strike, dried lubricant, loose hardware, damaged components—whatever is causing the problem.
We explain what we found in plain language. We tell you what repair is needed and what it will cost. If replacement makes more sense, we explain why and quote that option too.
We perform the repair
With your approval, we repair your lock on site. Depending on what’s needed:
Replace worn components: Pins, springs, cylinders, bolts—whatever components are worn or broken.

Why repair often beats replacement
You save money
Repair costs significantly less than replacement in most cases. Same security, lower cost. Smart financial decision when repair is viable.
Less disruption
Repair is usually faster than replacement. We fix what’s wrong and you’re done. Replacement involves removing old hardware, possibly modifying doors, installing new locks, and rekeying. More time, more work.
Preserve quality hardware
If you have good quality locks that just need maintenance or minor repair, keep them. Quality locks properly maintained last decades. No need to replace perfectly good hardware.
Keep existing keys working
Repair means your existing keys keep working. No need to cut new keys, redistribute to family members, update spare locations. Everything stays the same, just works better.
Maintain aesthetic
Especially in historic properties, original hardware has character. Repairing vintage locks preserves that character. Replacement with modern hardware changes the look completely.
Don't make it worse: Why DIY lock repair usually fails
We see DIY attempts gone wrong constantly. Here’s what NOT to do:
Don’t use WD-40 in locks: Everyone’s first instinct. But WD-40 isn’t lock lubricant. It’s a solvent. It initially loosens things but then attracts dirt and gums up mechanisms worse over time. Use graphite powder or silicone-based lock lubricant only.
Don’t force stuck locks: Forcing damages internal pins and springs. What could have been a $100 repair becomes a $200 replacement because you broke components by forcing.
Don’t try to file keys yourself: You’ll ruin the key and possibly damage the lock pins. Keys need precision cutting. Rough filing doesn’t work.
Don’t over-tighten screws: Especially in old Philly rowhomes with original wood doors. Stripped screw holes are expensive to fix properly. Snug is enough.
Don’t spray random lubricants inside: Wrong products damage lock internals. Oils attract dirt. Wrong viscosity prevents proper operation. Use proper lock lubricant or nothing.
Don’t try to take locks apart without knowledge: Lock mechanisms are precision devices. Springs fly out. Pins scatter. Reassembly is difficult without experience. You’ll end up calling us anyway, but now we’re fixing your attempt plus the original problem.
Lock repair looks simple but requires proper tools, knowledge, and technique. Call us first. Repair is cheaper than fixing DIY damage.
Prevent expensive repairs: Lock maintenance tips
Most lock repairs are preventable with basic maintenance. Here’s how to keep your locks working:
Lubricate yearly: Use graphite powder or silicone-based lock lubricant once a year. Insert into the keyway, work the key in and out several times. Prevents wear and sticking.
Don’t force keys: If your lock is getting sticky or hard to turn, call for service before it fails completely. Early intervention prevents bigger problems.
Check alignment regularly: If your door is getting harder to close or the lock doesn’t catch smoothly, alignment is shifting. Address it before the lock gets damaged.
Clean your locks: Dirt and debris cause wear. Gentle cleaning with compressed air removes buildup. Don’t spray liquid cleaners inside.
Replace worn keys: Worn keys damage lock pins. Get new keys cut from code or factory cuts, not copied from already-worn keys. Fresh keys extend lock life.
Address door problems: If your door is warped, sagging, or damaged, fix the door. Don’t let a door problem destroy a good lock.
Annual inspection: Have locks inspected annually, especially on commercial properties with heavy use. Preventive maintenance is cheaper than emergency repairs.
We offer lock maintenance service to keep your locks working smoothly and prevent expensive failures.

Yes. We have training and equipment to diagnose and repair smart deadbolts, keypad systems, electronic strikes, and access control hardware. Both mechanical and electronic components.
