Do you live in a place that is snowy and icy for a good portion of the year? The best thing that you can do to prevent problems with your keypad is to invest in one with a touch screen or to use key fobs. Fobs and proximity cards only need to be close to the keypad to cause activation, there are no buttons to worry about becoming frozen. The only thing you must concern yourself with going this route is ice buildup on the touchscreen. Keep that clear and you will be good to go.
As far as your gates go, the best thing to do is keep snow and ice from falling onto them. Routine upkeep on them by scraping off any ice and shoveling or plowing away snow as soon as it starts to build up is the best thing to do. If you want to get really advanced, some gates actually contain heater in the gearbox that is triggered on only when the temperature dips low enough. Before winter even starts to spit its snow, have a tech come out and maintenance it to make sure it is in tip-top running condition for the change of season. The biggest takeaway, though, is that snow needs to be removed and the area needs to be kept clear.
If your keypad has a hood around it and ice is becoming a problem, you could get a larger hood or have yours altered to make it more efficient. This is the most inexpensive winter fix and there are many different styles to choose from. If you are finding yourself taking care of this last minute, you can find common materials to fashion a makeshift hood that can temporarily carry you through.
Regardless of what kind of access control keypad or gate you have, it is wise to reach out to the manufacturer and installer is you continue to have issues. They may have a better solution or may even send out a tech to check it out. And ultimately, don’t wait until the bad weather is here. Be proactive and come up with a solution first!
