What this means for locks and safes here
Enterprise homes built 2005-2015 commonly used polymer-faced exterior keypads (cost-down spec). After ~5 years in summer UV, polymer faces yellow, crack, and admit dust into the electronics. We replace dozens of these per month with metal-faced keypads (e.g. Schlage BE469ZP) that survive the climate. Garage-door keypads see even worse exposure and fail at ~3-year intervals.
