One way to keep your locks from sounding like they are struggling is to invest in some 1.5V rechargeable batteries. They have a different chemistry than regular rechargeable batteries, but put out 1.5V per battery instead of 1.2V. Like most rechargeables, they maintain the voltage until they die suddenly. I just set a reminder on my calendar to charge them once every two months. They also work well in security systems.
