Several times a week, I see keyed entry locks on both sides of the deadbolt lock. Generally, I will see these in older properties or in rough neighborhoods where the home owner feels that they need this "added security". I will always make note of this condition to my clients and recommend that they get a licensed locksmith to re-key the lock and replace the interior lock with a thumb bolt. FYI keyed interior locks in new construction has been banned in most building jurisdictions.

Here's Why:

• I have several friends who are firefighters. They tell me horror stories of people who become disoriented or get in a "fight or flight" mode in a house fire. Being confused, the forget where the door key is located. Often firefighters find people dead from asphyxiation at one of the doors.
• The added security is no match for a person who wants to burglarize your property. If they want to get in, they will. Most door frames will not withstand the weight of a large person hurling themselves against the door. Not to mention a few well placed kicks.
• If the door has glass panels, bricks or patio furniture can allow some to gain entry rather easily.

Keep in mind that the main purpose of a doorway is a means in egress in the event of an emergency. Don't you or a loved one get caught dead at a doorway. Change keyed interior locks with thumb bolts. If you feel that you need more security, recommend checking with your local locksmith or home security representative for more information on how to make your home more secure.
