We had a similar problem at our gated flying field, the members were routinely pushing the dial wheels up - which made it somewhat easier for a non-member to gain access. So, we all agreed to set the dials to 0-0-0-0 when the lock was locked or just opened with the code. Our field is 150 feet (approx. 50 M) away and when leaving the lock (to fly, of course), the open lock is set to 0-0-0-0, so this year's code is unknown to any passerby and stays that way. We've had difficulties with BMX and RV
