Words from Senior Application Engineer Anthony Geato | Top of Page |

“The are multiple type of driveway gate locks available on the market today. The main two types of gate locks are solenoid locks and electromagnetic locks. Each type of gate lock has it advantages and disadvantages.
Before we discuss gate locks, I’d like to go over pin locks. These locks are made to lock your gate opener to the post or to your gate so that it helps prevent theft of your gate opener. These are simple devices that fit into the mounting locations on your gate opener, in place of the bolts that are provided in your gate opener kit.
Now let us talk about gate locking devices. The most popular type of gate locking device is the solenoid gate lock. All of these locks come with a control board and adequate an amount of wire needed to connect the gate lock to either the control board or to the master control board of your gate opener. These locks do not come with mounting hardware as each application will be unique to your gate.
We carry 3 brands of solenoid gate locks. The Estate Swing gate lock and Gate Crafters gate lock are essentially the same unit.
The GTO/PRO lock features a different type of locking tab when compared to the Estate Swing and Gate Crafters locks. The GTO/PRO locking tab has to slide back inside the unit, and this requires about 10 pounds of force to accomplish. One downside of this gate lock is that in heavy wind conditions the pin may become trapped behind the tab. Also if your gate opener has a soft stop feature, it needs to be disabled as there will not be enough force to latch the gate.
The Estate Swing and Gate Crafters lock feature a rolling type latch that takes minimal force to operate. The locking tab folds back into the unit and allow for easy locking and unlocking. In high wind conditions this lock will function the way it was intended, as the locking tab has a smooth back.
GTO/PRO also has a push to open/ open position gate lock. This is the exact same lock as the regular GTO/PRO gate lock, but it is made to either lock your gate in the open position or to be used as a push to open gate lock. To use this lock as a push to open gate lock, you will need to plan ahead with the installation however.
Gate Crafters also sells an electromagnetic gate lock. This gate lock is not compatible with solar gate opener because it is constantly drawing power. Also it the gate lock’s wire is cut, it will essentially turn this gate lock into a brick. This is due to the fact that this lock needs a constant source of electricity to function. This gate lock is ideal for high wind areas where you do not want to worry about your gate hanging up on your lock.
