How long do batteries typically last in electronic deadbolts? [solved]
I'm considering getting a Schlage Plymouth Keypad for our front-door but was curious how long the 9V battery typically lasts. The web site says "3 year battery life" but I'm... skeptical. =)
Has anyone used these types of locks before and if so, do the batteries need to be replaced often?

I've used something similar on my front door for about 4 years now (4xAA instead of a 9V) and it's great not having to carry keys everywhere. On average, I change the batteries about every 12-18 months. I guess it all depends on how often you use it and how worried you are about getting locked out. Personally I don't bother testing the batteries because mine beeps angrily when they start to get low.
I used one of these with 4xAA's in an apartment with 6 college students who themselves and friends were coming and doing all day long. It was an older model and lasted about 8 months on average, which seems like pretty good mileage. They are also good about warning you when the batteries are low.
Living without keys was great.
