For decades, turning a key in a lock was the only way to gain access to a home. When the cost of wireless technology became more affordable for consumers, security companies and locksmiths started looking for ways to keep up with the high-tech crowd. As a result, it is now possible to open your front door without using a key. Here are six ways home entry systems have improved due to advances in technology.

Programmable Codes

In the past, you had to change your security code every time you parted ways with a housekeeper or maintenance worker. Entry management systems now allow you to program different codes for each person who needs access to your home. If your landscaper quits, simply delete his code. The landscaper won't be able to gain entry to your house, but you'll be able to continue using your personal code without any problems.

Smartphone Key Copying

Gone are the days of having to wait in line at the local hardware store to copy your keys. Now making a copy is as easy as downloading an app and taking a picture of the key with your smartphone. The app detects the geometrical features of the key and allows you to order duplicates. One word of caution: keep your keys in your bag or pocket so other people aren't able to copy them with this type of app.

Remote Entry Management

There's no need to juggle a bag of groceries, a screaming baby, and a heavy diaper bag while you attempt to unlock your door. High-tech entry systems allow you to gain entry to your home by tapping a button. Some systems work with key fobs, while others are connected to smartphone apps. There are apps available for both iOS and Android phones.

Defined Entry Periods

If you've never worked with a service provider before, you may be hesitant to give out a code that would grant access to your home. There's really no way to tell if the worker will use the code appropriately or try to gain unauthorized entry at a later date. Fortunately, today's entry systems allow you to set defined entry periods for each code. If you expect a repairman to be at your home between noon and three o'clock, create a new access code and limit his defined entry period to those three hours on the day of your appointment.

Integrated Security Functions

Many keyless entry systems now have integrated security functions. With the right system, you can delete access codes remotely and keep an eye on your home via smartphone. If you already have a home security system, ask the monitoring company if an upgrade is available. You may be able to replace your existing security panel with one that allows for remote access and wireless functionality.

Safety Features for Parents

If your kids get home from school before you get home from work, an advanced home entry system makes it easy to keep tabs on them. Some apps are able to alert you if someone knocks on the door while your kids are home alone. These apps will also let you know if someone opens the door or your child uses her code to unlock a door unexpectedly. With these safety features, you will be able to keep your kids safe even if you are unable to be with them.

High-tech entry systems are convenient, but there is always a chance they will fail due to a power outage, dead battery, or tech failure. If you install one of these systems, be sure to keep a set of keys on you at all times. You should also have the number for your local locksmith service stored in your cell phone in case you are ever locked out of your home and need a professional to come to the rescue.
