Picture this: you approach your Gardall fire safe, enter your combination, and nothing happens. The keypad is unresponsive. Your valuables are locked inside, and you’re locked out. For one Melbourne, Florida homeowner, this nightmare scenario almost became reality—but early warning signs led them to call a professional locksmith before complete failure occurred.
The Safe Was Fine. The Lock Wasn’t.
Gardall fire safes have protected American homes and businesses since 1950. This particular unit was a well-maintained floor model with solid steel construction, proper fire rating, and years of service still ahead. But the electronic lock—a Sargent & Greenleaf Pulsetronic 2000 series—was deteriorating. Key-En-Lock | Locksmith Services Brevard County FL was called in to perform a proactive safe lock replacement before the safe became completely inaccessible.
Understanding Keypad Corrosion in Electronic Safe Locks
Electronic safe locks depend on keypads to receive combination input and transmit it to internal circuits. This means the keypad gets touched every single time the safe opens—making it the component most vulnerable to environmental damage. Humidity, temperature fluctuations, moisture from hands, and cleaning products all contribute to gradual corrosion of keypad contacts and internal circuitry.
The S&G Pulsetronic 2000 is a respected, UL-listed lock with over 150 years of manufacturer reputation behind it. Yet even quality locks cannot prevent the inevitable wear of electronic components exposed to regular contact and environmental stress. When corrosion develops inside the keypad, it creates electrical resistance that causes intermittent failures: sometimes the lock responds, sometimes it doesn’t. This unpredictable pattern is a clear warning sign of impending complete failure.
Why Cleaning Won’t Save a Corroding Lock
Many safe owners hope surface cleaning might restore a failing keypad. While mild surface corrosion sometimes responds to cleaning, intermittent failures indicate corrosion has penetrated the keypad membrane and internal circuit board contacts. Once that happens, no amount of surface cleaning will restore reliable function. Any temporary improvement would be short-lived; the underlying material degradation continues, and failure will return within weeks or months.
The Solution: LaGard 700 Lock Upgrade
Key-En-Lock replaced the failing Pulsetronic 2000 with a LaGard 700—a modern, reliable electronic lock that restored the safe to full operational status. This proactive replacement prevented the customer from facing an emergency lockout situation and the costly drilling that would follow.
