Are double keyed deadbolt locks illegal? In some locations, yes.
Double keyed deadbolt locks, often referred to as double cylinder locks, require a key to open from both the inside and outside. This design offers enhanced security, making it difficult for intruders to gain access even if they break a nearby window. Yet, these locks come with their share of concerns, notably safety during emergencies. If occupants can’t quickly locate the key, exit during fires or other urgent situations becomes challenging.
Many homeowners find the deadbolt lock with key on both sides beneficial for deterring break-ins, especially for doors with glass panels. Conversely, the double sided deadbolt with no key offers quick thumb-turn access on the inside but may compromise security. Some modern homes have incorporated the double key deadbolt smart lock, which fuses advanced technology with the principle of a double cylinder system. Retailers like Home Depot offer an array of double key deadbolt and double cylinder lock set options catering to diverse safety and aesthetic preferences.

Frequently Asked Questions (FAQs)
What Are Double Keyed Deadbolt Locks?
Double keyed deadbolt locks are security mechanisms that require a key to unlock from both the inside and outside of the door. Unlike traditional locks, where you might have a thumb turn on the inside, these locks demand a key on both ends. This design is particularly beneficial for doors with glass panels as even if the glass is broken, an intruder cannot simply reach in and turn the lock.
Do Double Keyed Deadbolt Locks Provide Better Security Against Breaking and Entering?
Double keyed deadbolt locks provide added security against breaking and entering by requiring a key to unlock the door from both the inside and outside. This makes it harder for intruders to bypass the lock using traditional ways to break a deadbolt lock, such as using a credit card or simple lock picking techniques.
Are Double Keyed Deadbolt Locks Illegal Everywhere?
No, double keyed deadbolt locks aren’t illegal everywhere. Their legality varies based on regional and local building codes. Some places permit them because of their enhanced security features, while others restrict or forbid their use due to safety concerns, especially during emergencies where rapid exit from the property might be vital.
Why Would Some Places Prohibit Double Keyed Deadbolts?
Safety during emergencies is a prime concern. Imagine there’s a fire in your home, and you need to make a quick exit, but you can’t find the key to unlock the door from the inside. Such scenarios have led certain regions to deem these locks as potential hazards, leading to regulations against their installation.
Can Double Keyed Deadbolts Be Used Alongside Other Locks?
Absolutely! Many homeowners choose to use double keyed deadbolt locks in conjunction with other lock types. For instance, a door might have a regular thumb-turn deadbolt and a double keyed deadbolt for added security. It provides flexibility – the regular lock can be used for everyday convenience, while the double keyed lock offers extra security when needed.
Are There Alternatives to Double Keyed Deadbolt Locks?
Yes, there are several alternatives that provide security without the potential safety risks. One popular option is the single cylinder deadbolt with reinforced plates, making it harder for intruders to break in. Moreover, modern smart locks come equipped with advanced security features that can be controlled remotely, marrying safety with convenience.
Do Insurance Companies Have a Preference for Lock Types?
Some insurance companies might offer discounts for homes with enhanced security features, including certain types of locks. While not all insurers differentiate between single and double keyed deadbolts, they do appreciate measures that reduce the risk of break-ins. It’s always a good idea to discuss with your insurance agent and understand their stance.
