If you lose your house keys, it can be a hassle to get into your home and then rekey or replace the locks. That's one reason some people are starting to go keyless.
Security professionals say it may be the easiest way to make sure you're never locked out again. Commercial businesses have used keyless door locks for years and now they're becoming popular with homeowners, too.
"It is a lot more convenient not to have to carry a key. It's more convenient to not have to rekey your locks if you've given out a key, and again, you're so much more likely to lock the door when you don't have to have your keys with you," says security professional Mary Tinder.
A basic keyless lock system is about four times more expensive than a traditional deadbolt. A push-button lock can be installed for around $200. Just punch in your pre-programmed code and you're in.
Angie Hicks, founder of Angie's List adds, "Many people like a keyless lock system because it allows them to do away with that spare key hidden under a flower pot outside. It really gives them peace of mind that their house is more secure."
"That's huge because people can watch you, where you get your key and, unfortunately, people get to depend on that hidden key under the mat. It's such a classic place, but I know some people who would do that," says Tinder.
Newer, more expensive systems use a digital keypad and wireless technology to open the door. Whenever a programmed key fob or smartphone gets in close proximity to the door, a signal is automatically sent to unlock.
Keyless systems are more secure than handing out a key. If there's no key, there's no way to make a copy. You simply change the code, to prevent the person from getting into your home, without permission.
If you go with a push-button system, experts recommend changing your pass code occasionally, to keep the buttons from wearing down, and preventing someone from guessing the code.
Most keyless locks run on AA or AAA batteries and also come with a key bypass just in case you forget the code or lose the fob or phone that triggers the lock.
