Additionally, homeowners claim the locks enable them to keep their doors locked more often, given the fact that they are so easy to unlock. Their ease of use is also an advantage in emergency situations like fires that might require people to exit the building in a hurry. Traditional locks that have to be keyed may pose a significant risk in these scenarios.

It is relatively easy to fix slow locks. The problem mostly occurs when your locks accumulate grime and dirt particles over time. You can attempt a Do It Yourself method to fix this issue. Insert a cotton swab, or any other soft cleaning material into the lock to attract the dirt particles.

Always use graphite to lubricate all your slow locks. You can also use silicone spray in case graphite is unavailable or inefficient in your slow door lock.

Forcing a key into a door lock could cause even more serious damages to your lock, such as breaking the key inside the lock. If your door lock has lock seizures, you could try lubricating the lock with silicone spray or graphite. If this method does not work for your scenario, you should probably call a lock expert.

3. Stuck Bolt or dysfunctional Lock

Mechanical issues almost always cause stuck bolts and lock failures. If your lock has this problem, it is advisable to attempt finding a lock expert that can find the source of your lock problem. However, more often than not, it is not worth it trying to fix the issue.

Locks with stuck bolts cost almost the same to replace and to fix. Obviously, it is wise to replace it rather than struggle with fixing the faulty sliding door lock.

5. Key inserting problems

A number of factors can lead to you being unable to insert a key into your lock. However, you must make sure you are trying to use the right key because some keys may not be modelled to fit into your lock’s keyhole.

While it might seem straightforward to many people, solving this issue might require you to think outside the box. If the key that broke is a newly-cut key, there is a chance the key was poorly cut. It is for this reason that it is essential to find an experienced and reliable locksmith to make copies of your keys for you.

Another way of preventing the scenario is by using smart locks on your sliding glass doors. If the issue is not resolved, it is advisable to contact a qualified locksmith to get the issue resolved. Some manufacturers will even offer to make a new key for you free of charge.
