Inventor Aims to Stop Break-Ins

Bump keys make opening locked doors easy, and few products address the problem. The most common way of dealing with the risk is to change the lock to a 'high security' type that can cost $100 or more per lock. However, an inventor created a product that fits nearly every door, and stops bump keys cold for ~$15 called the "Lock Locker". Is this product a stroke of genius, or is potentially life threatening? We look deeper in this note.

Preventing the thumbturn on deadbolts from turning is really the only way to stop lock bumping or picking - but only when the locked room is occupied. Chair-under-doorknob is how I've always done it (especially with interconnecting hotel room doors; I never trust those weird one-sided knobs) - though I admit no red team testing has ever been done to quantify the efficacy of this method.

These guys have devices that do essentially the same thing and they all appear marketed heavily towards 'travelers' or others who find themselves sleeping or bathing in unfamiliar places:

Super Grip Lock - over the thumbturn strap

Add-A-Lock - linchpin style

Lock Jaw - slide-over form factor like the LockLocker

Of course, they all suffer the drawbacks you mention above by preventing the normal deadbolt locking mechanism from working.

Marty, I seriously bow down to your knowledge of these types of 'anti-bump' devices. An interesting list, for sure.

To all the frequent travelers in the group: Do you own/use a device like these?

No, instead I try not to book hotels in sketchy neighborhoods. Unless they have really good nightlife, in which case I'm not in my room anyway :)

Marty, nice list! I've embedded those videos in your original response to make it easier for people to view / compare.
