An electronic lock service organization was receiving many call backs for malfunctions in electronic locks they installed. The repeated service calls for the same issue was going on endlessly. After usually 2-3 weeks they had to make repeat calls. Since they were mostly warranty calls, it was costing them a lot of money.
The problem was due to oxidation, arcing and weathering of the contact points. Finally they were directed to use DeoxIT® to clean the pins and in some severe areas, they would followup with DeoxIT® SHIELD to provide longer lasting protection. The result was a significant reduction in service calls. Instead of going back every 2-3 weeks, they would only need to go back to a few every 4-6 months. The rest were taken care off, once or so a year as general system maintenance.
