1. Lubrication

In most cases, a well-done lubrication job is all that is needed to fix a sliding door lock issue. This fix is not always permanent, but can get your sliding door open for further repairs or replacement. Note that the best door lock lubricants will not use an oil base. If you end up using standard WD-40 or other oily lubricants, the liquid residue will eventually attract dust and other debris, causing a clutter of dust to be built. If the lock is open and the door will not move, lubricate the track. Though if you are trying to fix a sliding door lock, apply the lubricant inside any keyways. 

If you are to decide to use a lubricant, be sure to apply it directly onto the parts of the lock that are not moving. If internal components are not accessible, apply lubricant into crevices that lead to internal components.


2. Door Fixes

Sometimes, the problem could be the door itself. This is quite common to occur for sliding door locks. Because the track is so long and the tolerances are so tight, any disruption to that surface is going to affect the door’s ability to open. If you wish to increase the security of your sliding glass door then the best option for you would be to block the tracks so that the door cannot open. This may also happen unintentionally and noticeably with the same type of debris accumulation that happens inside locks.
