Mul-T-Lock Cronus High Security Grade 2 Single Cylinder Dead-Bolt w/Thumb Turn 2-3/8 or 2-3/4 Adjustable Backset for Commercial and Residential Metal Or Wood Doors (Stainless Steel) - desertcart.com

Review: A Bargain Premium-class Deadbolt - If you're thinking $5-15 deadbolts are, at best, better than no deadbolt at all, you're correct. If you're not thinking that, you stand to be corrected. Your only online or local hardware/big-box store choice is a step up to the $35-40 price point. The Kwikset 980 is demonstrably bump and pick proof but armored just beyond slightly effective. (Since 2016, their Advanced Smartkey locks can no longer be opened with force tools.) The Schlage B60 is heavily armored but is easily bumped with a $5 key; their SC1 5-pin cylinder is pathetically obsolete. The next step up is to high-security deadbolts that run $150-200 for "light commercial" products. Real ones go for $300-400. Except for the lone wolf in the pack: The affordable Mul-T-Lock MD1 and MD2, the Cronus single and double cylinder. It's built like a tank and fitted with high security cylinders and keys having telescopic pin-within-pins, multiple shear lines and bitting. And that's just for starters. Sold here is the Junior with the five chamber 008J platform normally marketed as the 008 (was 006), known as the Classic. "Junior" is just the name for Mul-T-Lock's retail marketing program for several general purpose items from their 100's of otherwise specialized products. Among the Juniors are padlocks, plugs/cylinders, a lockset and the Cronus. The "not-Junior" products are fitted with the big-bucks ClassicPro (x86x), Interactive (206SP) or MT5+ (616B) platforms or even bigger-buck platforms. There is nothing junior about the Junior Cronus and its 008J. NOTE: The drawing and illustration images I've pulled from Mul-T-Lock docs shows two side cuts on the 006/008 key. The 008J key has a third side cut which runs through the area used in the more advanced platforms. One might presume this is to prevent locksmiths from buying blanks under the Junior program price points and cutting premium keys on the cheap. The images nonetheless present accurately the Classic lock/tumbler technology in the Junior Cronus. Concerning the bad guy standing at your home's door, you should Google "ansi grade 1 vs 2" to understand it's irrelevant in this discussion. Fully Grade 2, this Cronus is a good leap beyond any $15-40 marginally Grade 1 deadbolts you'll buy online or at the local hardware or big-box store. Your neighborhood store won't have Mul-T-Lock key blanks and cutting machines. See the Mul-T-Lock website for the local locksmiths, if any, where you live and you'll need to show your duplication authentication card. Don't throw it out with the packaging! Slsupply can provide more (now or later) than the three keys included with the Junior Cronus but not as Prime or Fulfilled by desertcart. As well, they filled my order for two locks and six keys, all keyed alike. Message them for ordering instructions. Mul-T-Lock's scale up product is their Grade 1 Hercular (HD1, HD2, HDC). If you can afford it (and you'd unlikely be here if you could), only some bragging rights is what you'll get for your cost effective and practical home owner needs vs the Cronus. I've combined a Cronus deadbolt with a Kwikset SmartKey lever on each of my outward opening steel security doors. Getting past this will require determined and appreciable destruction - a necessity when filing a breaking and entering claim with the insurance company.
Review: High quality lock. - High quality lock. Not difficult to install however if you're replacing an old dead bolt it's very possible that the hole cut in the door that the lock is mounted in is not in the proper position for this lock. Less expensive or old dead bolts are a little too close to door jam. That what happened to me. Still, this is a high quality item that I am keeping. I'll figure it out.

## Questions & Answers

**Q: Why is this (junior cronus) so much cheaper than the interactive+ cronus?**
A: Junior is one step below “high security”. It doesn’t provide drill resistance nor does it really prevent unauthorized key duplication. 
If you’re going for budget - Junior is better than any standard deadbolt. If you want good security I recommend to go one step up to Cronus Interactive+
Mul-T-Lock Interactive+ Cronus High Security Grade 2 Single Cylinder Dead-Bolt w/Thumb Turn 2-3/8 or 2-3/4 Adjustable Backset for Commercial And Residential Metal Or Wood Doors (Stainless Steel) https://www.amazon.com/dp/B07D7HSZDL/ref=cm_sw_r_cp_api_9elVBb3AHBHTR

**Q: Do you have this in a double cylinder version? Keyed on both sides**
A: This is one step up - the INTERACTIVE+ version:
MUL-T-LOCK Double Cylinder Cronus DEADBOLT Interactive+ (Stainless Steel) https://www.amazon.com/dp/B07HFKFFY2/ref=cm_sw_r_cp_api_glt_fabc_Y8ZX0GFQ2MABN7K51SK1

**Q: Where can i find a locksmith familiar with mul-t-lock in the greater wilmington nc area?  no luck with corporate in brooklyn.**
A: It’s a pretty simple lock to install you might have to drill a deeper opening in your door. 
As I’ve installed this lock myself with a cordless drill and wood drill bit...

**Q: Is the junior cronus really bump proof and pick proof? and is the key control really not secure? i ask because i have a very clever nut stalker**
A: I am not sure how 'bump proof' this lock is, but the key is unique (like the old Lexus car keys that are smooth on the outside and ridges cut on the inside).  Blank keys are not sold at Home Depot, so you would need to go to a specialized locksmith to buy a compatible blank to test if it is bump proof.

### ⭐⭐⭐⭐⭐ Better than most homeowner grade dead bolts
*by M***N on January 7, 2026*

Well built. Key has dimples in the side instead of teeth. I would say it’s more secure than homeowner grade locks. Key is big with a plastic head so it’s easier to find in the dark
