Mend A Sticky Lock
As crucial as locks are to safeguard houses and their residents, the majority of people don’t take them seriously or even consider their maintenance until they stop functioning as intended. It’s only then that they realize the importance of locks. A common issue is sticky locks although, there are plenty of quick fixes for it.
For starters, you can try by lathering a little graphite powder on the key. A second option would be rubbing the lead point of a pencil on the key’s outer surface. Squirting GT85 lubricating spray directly into the lock may help. If that doesn’t work, you can always call a locksmith.
