Most locksmiths recommend changing the lock on a door every seven years. If you haven't experienced any security issues, it's still a good idea to switch out your locks from time to time. You don't need to replace them every few months, unless that's how often you've had to in the past. If you're unsure if your locks need to be updated, consult a locksmith.
In some cases, the problem may be with the door or frame, and you can make adjustments to get the lock to fit. In other cases, you may need to switch to a higher-quality door knob or lever. If the bolt is stuck due to poor quality materials, no amount of lubricant or adjusting its position will fix it. Choose hardware that has been tested and has an A rating and the highest certification for durability.
A door lock is an important part of your door, and you want it to last. A quality lock can last for decades, so you should expect your padlock to last around seven years. Door locks last longer if they are properly maintained and installed correctly. When was the last time you changed the locks on your doors?.
