The locks on your property keep your home and household safe. But over time daily use and exposure to the elements can wear away your security system. Leaving your home vulnerable to intruders and break ins. Luckily, locks don’t fail without warning. These are some signs that your locks need replacing.
10 signs your lock needs replacing:
- Difficulty turning the key
Fighting with the lock to open the door is indicative of internal lock issues. Debris and dirt can build up inside the lock, making it difficult to turn the key and open the door. It may also mean the internal pins or springs are wearing out, resulting in misalignment. If left unfixed you could be dealing with a seized lock, snapping key, or stuck locked out of your property.
- Stuck key
If your key’s getting stuck repeatedly, the lock’s mechanism is jammed. This often happens due to broken pins, rust, or debris that’s built up in or corroded the keyway. Replacing your lock quickly helps you avoid snapping your key inside it. This way, you won’t need to call a locksmith for key extraction.
- Loose door handle
Worn screws or internal components can result in a loose door handle or lock. A relaxed or loose handle makes it easier for intruders to tamper with the lock or force the door open. Tightening screws or worn parts with a screwdriver can help for now. But it’s important to see this as a sign to update your locks. Doing so can boost your home security.
- Sticky lock operation
Locks should work smoothly and seamlessly. Constant friction suggests internal wear, dirt or lack of lubrication. Living in a coastal or humid area can also lead to progressed corrosion of your locks as a result of the salty sea air. Cleaning and lubricating can help locks last longer. However, if you keep struggling with sticky locks, you might need to replace them.
- Misaligned deadbolt
When your deadbolt works well, it should sit flush and slide easily into the strike plate. If you’re having to wiggle or force the lock, the strike plate, deadbolt, door frame or hinges may have shifted. A locksmith can fix this by realigning the door and adjusting the lock for better function.
- Loud locks
Unusual noises when locking or unlocking the door can be a warning sign of failing locks. If you hear creaking or scraping sounds when you fasten your door, parts like springs or pins might be wearing out. Sometimes this can be fixed with lubrication to help the metal components along. But it’s best to call a locksmith if you want some extra assurance.
- Door not latching properly
Latch misalignment or lock damage can cause the deadbolt or latch to not engage fully. This leaves the door insecure even when locked. Tighten or shim the hinges, adjust the strike plate, and fix stripped screw holes. These steps can help your door latch properly if you don’t think a replacement is the right choice for now.
- Visible corrosion or rust
Locks on your front door, back door, outbuildings and gates are exposed to the elements. Therefore, they are susceptible to rust and corrosion. Rust weakens the metal components of the locks which can cause them to fail – putting your security at risk. For small patches of rust inside the lock you can spray oil into the keyway. For removable locks you can soak in white vinegar. But for severe rust, replacement is best.
- Age over 10-15 years
Even without obvious damage or warning signs, mechanical components degrade over time. When your lock is approaching a decade of service it’s time to consider a replacement. Being aware of the risks involved with an aging lock means you can avoid emergency lock-outs, snapping keys and failed security.
- Key breaks inside the lock
If your key has broken in the lock, you might not only need a new key but a lock replacement too. A cracked or weakened key indicates the lock’s internal components are deteriorating. A broken key is a tell-tale sign that your lock is jamming and not operating smoothly.
