Over time, a door lock can become worn and may eventually need to be replaced with constant use. Often parts like the lock itself can jam and get stuck and you might wonder if it’s a job you can do yourself or need to bring in a pro to handle.
A visit from a locksmith can cost $50 – $100 per hour and that’s not including parts that you might require. So before you call one, you might want to try a few things on your own to see if you can take of things without paying for help.
There are a few potential causes for a door lock that won’t turn, such as a jammed or misaligned latch, a problem with the key, or an issue with the lock mechanism itself. Here are some steps you can try to fix the problem:
- Check the latch: Make sure the latch is properly aligned with the strike plate on the door frame. If it is not, gently adjust it until it lines up.
- Clean the key: If the key is dirty or corroded, it may not be able to turn in the lock. Clean the key with a small brush and some lubricant, such as WD-40.
- Lubricate the lock: Spray some lubricant, such as graphite powder or silicone spray, into the keyhole to help loosen any debris or rust that may be preventing the lock from turning.
- Check the lock mechanism: If the problem is with the lock mechanism itself, you may need to disassemble the lock and inspect it for any issues. If you are not comfortable doing this, it may be best to call a locksmith.
- Check the door alignment: Make sure the door is properly aligned in the frame. If it’s out of plumb, it will cause the lock to bind and not turn.
- Try another key: If you have another key to the lock, try it to see if it works. If it does, then the problem is with the original key and not the lock.
If the problem persists, it may be best to call a locksmith for further assistance at this point. It’s possible that the locking mechanism may need to be changed completely if it is not worth fixing and is simply beyond repair.
If you have to replace your lock
The lifespan of a door lock can vary depending on the type of lock, the quality of the lock, and how often it is used.
A high-quality, well-maintained mechanical lock can last for decades, while a cheaper, lower-quality lock may only last a few years.
A typical mechanical lock that is used regularly can last anywhere from 5-20 years.
Electronic locks can have a shorter lifespan, and may need to be replaced after a few years of use, due to the electronic components wearing out.
Proper maintenance of your lock can help to extend its lifespan. Lubricating the lock with graphite powder or silicone spray can help to keep the mechanism working smoothly, and keeping the lock clean can help to prevent rust and corrosion.
It’s also recommended to change the lock if you have lost your key or if you suspect that your lock has been tampered with.
In any case, it’s always a good idea to have a locksmith inspect your locks periodically to ensure that they are in good working condition.
