Hi @Rocjo,
It can be frustrating, especially when standard methods like WD40 don’t seem to help.
First, after applying WD40, try gently winding the locks in both directions — in and then out — repetitively. This back-and-forth motion can sometimes help loosen any rust or gunk that’s causing the mechanism to seize. Be patient, as this can take a little time, but sometimes, this motion can get things moving again.
If that doesn’t work and the lock is still entirely stuck, it's possible that the internal mechanism is so rusted or corroded that it’s beyond repair. In such cases, replacing the lock might be the only viable option. I recently worked on some older locks that were similarly rusted and couldn't be unseized, no matter how much penetrating oil was used. Unfortunately, replacing the lock was the only solution.
When you go to replace the lock, make sure to choose a compatible model from Whitco, or consider alternative options that fit the existing mechanism. If you're unsure, a professional locksmith or the supplier might be able to recommend the best replacement lock for your needs.
It's always a good idea to inspect the locks regularly, as rust can build up over time. To prevent future issues, you might want to consider applying a silicone lubricant instead of WD40 for long-term maintenance. This can help protect the internal parts and reduce the risk of future seizing.
Please let me know if you have any questions.
